    InWaterSense: An Intelligent Wireless Sensor Network for Monitoring Surface Water Quality to a River in Kosovo2018In: International Journal of Agricultural and Environmental Information Systems, ISSN 1947-3192, Vol. 9, no 1, p. 39-61Article in journal (Refereed)
    Abstract [en]

    A shift in water monitoring approach from traditional grab sampling to novel wireless sensors is gaining in popularity not only among researchers but also in the market. These latest technologies readily enable numerous advantageous monitoring arrangements like remote, continuous, real-time, and spatially-dense and broad in coverage measurements, and identification of long-term trends of parameters of interest. Thus, a WSN system is implemented in a river in Kosovo as part of the InWaterSense project to monitor its water quality parameters. It is one of the first state of the art technology demonstration systems of its kind in the domain of water monitoring in developing countries like Kosovo. Water quality datasets are transmitted at pre-programmed intervals from sensing stations deployed in the river to the server at university via the GPRS network. Data is then made available through a portal to different target groups (policy-makers, water experts, and citizens). Moreover, the InWaterSense system behaves intelligently like staying in line with water quality regulatory standards.

    A Machine Learning Driven IoT Solution for Noise Classification in Smart Cities2018In: Machine Learning Driven Technologies and Architectures for Intelligent Internet of Things (ML-IoT), August 28, 2018, Prague, Czech Republic, Euromicro , 2018, p. 1-6Conference paper (Refereed)
    Abstract [en]

    We present a machine learning based method for noise classification using a low-power and inexpensive IoT unit. We use Mel-frequency cepstral coefficients for audio feature extraction and supervised classification algorithms (that is, support vector machine and k-nearest neighbors) for noise classification. We evaluate our approach experimentally with a dataset of about 3000 sound samples grouped in eight sound classes (such as, car horn, jackhammer, or street music). We explore the parameter space of support vector machine and k-nearest neighbors algorithms to estimate the optimal parameter values for classification of sound samples in the dataset under study. We achieve a noise classification accuracy in the range 85% -- 100%. Training and testing of our k-nearest neighbors (k = 1) implementation on Raspberry Pi Zero W is less than a second for a dataset with features of more than 3000 sound samples.

    IoT-based Urban Noise Identification Using Machine Learning: Performance of SVM, KNN, Bagging, and Random Forest2019In: Proceedings of the International Conference on Omni-Layer Intelligent Systems (COINS '19), New York: ACM Publications, 2019, p. 62-67Conference paper (Refereed)
    Abstract [en]

    Noise is any undesired environmental sound. A sound at the same dB level may be perceived as annoying noise or as pleasant music. Therefore, it is necessary to go beyond the state-of-the-art approaches that measure only the dB level and also identify the type of noise. In this paper, we present a machine learning based method for urban noise identification using an inexpensive IoT unit. We use Mel-frequency cepstral coefficients for audio feature extraction and supervised classification algorithms (that is, support vector machine, k-nearest neighbors, bootstrap aggregation, and random forest) for noise classification. We evaluate our approach experimentally with a data-set of about 3000 sound samples grouped in eight sound classes (such as car horn, jackhammer, or street music). We explore the parameter space of the four algorithms to estimate the optimal parameter values for classification of sound samples in the data-set under study. We achieve a noise classification accuracy in the range 88% - 94%.

    Cross-Platform Mobile Development: Challenges and Opportunities2013In: ICT Innovations 2013: ICT Innovations and Education / [ed] Vladimir Trajkovik and Misev Anastas, Springer, 2013, 1, p. 219-229Chapter in book (Refereed)
    Abstract [en]

    Mobile devices and mobile computing have made tremendous advances and become ubiquitous in the last few years. As a result, the landscape has become seriously fragmented which brings lots of challenges for the mobile development process. Whilst native approach of mobile development still is the predominant way to develop for a particular mobile platform, recently there is shifting towards cross-platform mobile development as well. In this paper, we have performed a survey of the literature to see the trends in cross-platform mobile development over the last few years. With the result of the survey, we argue that the web-based approach and in particular,hybrid approach, of mobile development serves the best for cross-platform development. The results of this work indicate that even though cross platform tools are not fully matured they show great potential. Thus we consider that cross-platform development offers great opportunities for rapid development of high-fidelity prototypes of the mobile application.

    Association Rule Mining with Context Ontologies: An Application to Mobile Sensing of Water Quality2016In: Metadata and Semantics Research: 10th International Conference, MTSR 2016, Göttingen, Germany, November 22-25, 2016, Proceedings / [ed] Garoufallou, E., Subirats Coll, I., Stellato, A., Greenberg, J, Cham: Springer, 2016, p. 67-78Conference paper (Refereed)
    Abstract [en]

    Internet of Things (IoT) applications by means of wireless sensor networks (WSN) produce large amounts of raw data. These data might formally be defined by following a semantic IoT model that covers data, meta-data, as well as their relations, or might simply be stored in a database without any formal specification. In both cases, using association rules as a data mining technique may result into inferring interesting relations between data and/or metadata. In this paper we argue that the context has not been used extensively for added value to the mining process. Therefore, we propose a different approach when it comes to association rule mining by enriching it with a context-aware ontology. The approach is demonstrated by hand of an application to WSNs for water quality monitoring. Initially, new ontology, its concepts and relationships are introduced to model water quality monitoring through mobile sensors. Consequently, the ontology is populated with quality data generated by sensors, and enriched afterwards with context. Finally, the evaluation results of our approach of including context ontology in the mining process are promising: new association rules have been derived, providing thus new knowledge not inferable when applying association rule mining simply over raw data.

    A design study investigating augmented reality and photograph annotation in a digitalized grossing workstation2017In: Journal of Pathology Informatics, ISSN 2229-5089, E-ISSN 2153-3539, Vol. 8, article id 31Article in journal (Refereed)
    Abstract [en]

    Context: Within digital pathology, digitalization of the grossing procedure has been relatively underexplored in comparison to digitalization of pathology slides. Aims: Our investigation focuses on the interaction design of an augmented reality gross pathology workstation and refining the interface so that information and visualizations are easily recorded and displayed in a thoughtful view. Settings and Design: The work in this project occurred in two phases: the first phase focused on implementation of an augmented reality grossing workstation prototype while the second phase focused on the implementation of an incremental prototype in parallel with a deeper design study. Subjects and Methods: Our research institute focused on an experimental and “designerly” approach to create a digital gross pathology prototype as opposed to focusing on developing a system for immediate clinical deployment. Statistical Analysis Used: Evaluation has not been limited to user tests and interviews, but rather key insights were uncovered through design methods such as “rapid ethnography” and “conversation with materials”. Results: We developed an augmented reality enhanced digital grossing station prototype to assist pathology technicians in capturing data during examination. The prototype uses a magnetically tracked scalpel to annotate planned cuts and dimensions onto photographs taken of the work surface. This article focuses on the use of qualitative design methods to evaluate and refine the prototype. Our aims were to build on the strengths of the prototype's technology, improve the ergonomics of the digital/physical workstation by considering numerous alternative design directions, and to consider the effects of digitalization on personnel and the pathology diagnostics information flow from a wider perspective. A proposed interface design allows the pathology technician to place images in relation to its orientation, annotate directly on the image, and create linked information. Conclusions: The augmented reality magnetically tracked scalpel reduces tool switching though limitations in today's augmented reality technology fall short of creating an ideal immersive workflow by requiring the use of a monitor. While this technology catches up, we recommend focusing efforts on enabling the easy creation of layered, complex reports, linking, and viewing information across systems. Reflecting upon our results, we argue for digitalization to focus not only on how to record increasing amounts of data but also how these data can be accessed in a more thoughtful way that draws upon the expertise and creativity of pathology professionals using the systems.

    Integrating MOOCs in Regular Higher Education: Challenges and Opportunities from a Scandinavian Perspective2018In: Learning and Collaboration Technologies: Design, Development and Technological Innovation. LCT 2018 / [ed] Panayiotis Zaphiris and Andri Ioannou, Springer, 2018, Vol. 10924, p. 193-204Conference paper (Refereed)
    Abstract [en]

    MOOCs are increasingly being considered by universities as an integral part of their curriculum. Nevertheless, there are several challenges that to some extent slow this process, where the most important one is the accreditation challenges and financing. These challenges are particularly important in the context of universities in Scandinavian countries where education is mostly free. In order to gain more insights on the status of proliferation of MOOCs in Scandinavian universities and understand any specific challenges, we conducted a study by analyzing two sources of data: research publications and university websites. Further on, these data have been analyzed using a framework that differentiates and categorizes MOOCs in terms of accreditation and scalability. As a result of this analysis, we have identified the remaining challenges as well as a number of opportunities regarding the full integration of MOOCs in the educational system of the Scandinavian Higher Education Institutions.

    Exploring the Impact of Social Learning Networks in M-Learning: a Case Study in a University Environment2017In: Learning and Collaboration Technologies Novel Learning Ecosystems: 4th International Conference, LCT 2017, Held as Part of HCI International 2017, Vancouver, BC, Canada, July 9-14, 2017, Proceedings, Part I / [ed] Panayiotis Zaphiris, Andri Ioannou, Vancouver: Springer, 2017, p. 189-198Conference paper (Refereed)
    Abstract [en]

    The high penetration of Internet, advances in mobile computing and the rise of smartphone usage has largely enhanced the use of social media in education. Moreover, nowadays social learning network (SLN) platforms have become an important educational technology component in higher education. Despite the fact that SLN are becoming ubiquitous in the higher education, there is relatively not much empirical work done investigating their purposefulness when integrated into the learning activities. This paper aims at exploring the impact of SLN in mobile assisted learning and to provide empirical evidence as to what extent SLN and mobile learning (M-learning) can improve the learning experiences. For this purpose, a quantitative experimental approach is used, and two survey questionnaires were conducted. The data is collected from 120 participants. In this study, we focus our intention on Edmodo and Kahoot platforms, which represent social media based tools that aid and support collaboration, knowledge sharing and group activities among students. Computer science students of the Tetovo University (TU) used these tools throughout one semester. From this study, there is significant evidence that students are very interested to use this SLN in a M-learning setting, indicating that SLN can be one of the promising pedagogical technologies that could contribute effectively to learning process.

    Rethinking the conventional learning paradigm towards MOOC based flipped classroom learning2017In: 16th International Conference on Information Technology Based Higher Education and Training (ITHET), 10-12 June, 2017, Ohrid, Macedonia, IEEE, 2017, article id 8067791Conference paper (Refereed)
    Abstract [en]

    The recent proliferation of Massive Open Online Courses (MOOCs) has initiated a plethora of research endeavors revolving around new pedagogical methods in higher education. Integrating MOOCs in blended learning can be beneficial in different ways for both learners and instructors. In this position paper, we aim to provide a brief and comprehensive review about the challenges that higher education institutions in Macedonia and Kosovo face while coping with the new trends of flexible or blended learning. Moreover, after describing some real cases of MOOC based flipped classroom learning, we also provide some recommendations in order to enhance and enrich learning experience by employing innovative pedagogies.

    Use of a Smart TV as a Platform for Social Engagement for Senior Citizens2015In: 7th ICT innovations Conference 2015: Web proceedings / [ed] Suzana Loshkovska, Saso Koceski, Skopje, Macedonia: Association for Information and Communication Technologies , 2015, p. 96-105Conference paper (Refereed)
    Abstract [en]

    The number of studies investigating computer use or other technologies used by senior citizens has progressively increased in the last twenty years. The interest stems from a diverse range of research disciplines including human computer interaction, education, and many others. Senior citizens generally have a positive attitude towards technology, and they are willing to use the product if they need it. Positive attitudes are also more likely to be expressed towards devices used every day at home, such as the television, microwave etc. Even if those devices are now typically digital, senior citizens are familiar and comfortable with them. These characteristics drive us to offer a solution by rethinking the use of some existing technologies and making them more affordable and accessible to older people. It is offered on a TV, something that senior citizens are familiar and comfortable with and which most of them have it at home. On this research we report our experience on developing a prototype service using smart TV application specifically tailored for the senior citizens needs and requirements. Based on the findings, we can conclude that there was great acceptance from senior citizens for the support of daily living and the ability to control their daily activities provided by this service.

    Augmenting requirements gathering for people with special needs using IoT: A position paper2016In: CHASE '16: Proceedings of the 9th International Workshop on Cooperative and Human Aspects of Software Engineering, ACM Press, 2016, p. 48-51Conference paper (Refereed)
    Abstract [en]

    Requirements gathering are an important aspect of application development, especially when users are people with special needs. Traditionally, this process is being conducted using conventional methods, such as interviews, workshops and questionnaires. These approaches, however, are unable to grasp the full context when collecting data from the communities of people with special needs, mainly because of the difficult access to participants and incomprehensiveness of the data gathered. To mitigate such issues, in this position paper, we argue that existing traditional methods could be complemented by means of Internet of Things. The immense amount of data gathered from various devices interconnected could help generate meaningful data that will complement the usually insufficient amount collected using traditional methods. This new approach is, however, associated with challenges that are discussed along with a possible scenario on how data complementing from traditional and the indirect method could be done.

    Accessibility Requirements for Blind and Visually Impaired in a Regional Context: An Exploratory Study2014In: 2014 IEEE 2nd International Workshop on Usability and Accessibility focused Requirements Engineering (UsARE) / [ed] Shah Rukh Humayoun, Norbert Seyff, Nauman A. Qureshi, Anna Perini, Achim Ebert, David Callele, and Simone D. J. Barbosa, IEEE Press, 2014, p. 13-16Conference paper (Refereed)
    Abstract [en]

    At the time when we are debating the Internet as a human right, an access to basic online information is a challenge for blind and visually impaired community. Steps taken for their digital inclusion, such as, the Web Content Accessibility Guidelines (WCAG) are often insufficient. In this paper we present initial requirements gathered during three workshops organized with various stakeholders coming from three different countries. Initial results suggest that the context of use and the cultural dimension play a crucial role in making digital content accessible for this community. Additionally, a one-solution-fits-all model is inadequate without considering levels of visual impairment when providing customized web and mobile experience. Finally, we lay out challenges that with comprehensive requirements gathering in the future, could address various problems that blind and visually impaired face.

    Abstract [en]

    Access to web content continues to be a challenge for the visually impaired, as the needs of such community are very diverse. The access is further hindered by the fact that designers continue to build websites non-compliant with Web Content Accessibility Guidelines (WCAG). To better understand the needs of the visually impaired community, three workshops were organized with various stakeholders coming from three different countries. The results from the workshops suggest that one-solution-fits-all model is inadequate without considering the levels of visual impairment when providing customized web experience. A set of requirements devised from the workshops guided the process of building a middleware prototype. Using eight adaptation techniques, the prototype provides the required user experience based on users level of visual impairment. Preliminary evaluation of the middleware suggests that several adaptation techniques perform better with non-WCAG compliant websites compared to those being compliant.

    Systems integration challenges for supporting cross context collaborative pedagogical scenarios2012In: Collaboration and Technology: 18th International Conference, CRIWG 2012 Raesfeld, Germany, September 16-19, 2012 Proceedings, Raesfeld: Springer, 2012, Vol. 7493, p. 184-191Conference paper (Refereed)
    Abstract [en]

    This paper discusses the potential and challenges of integrating collaborative and mobile technologies in order to support a wide variety of learning activities across contexts. We present and illustrate two examples of such integrations aiming to expand the functionalities of an existing CSCL environment by introducing mobile technologies. Our goal is to enable the design and enactment of pedagogical scenarios that include asynchronous learning, outdoor collaborative activities and tasks performed in class using personal response systems. These examples are used to identify and analyze different challenges related to software systems integration issues. The outcome of these efforts is a proposed cross context systems integration model that can serve as the basis for future work that leads towards the integration of additional mobile applications designed and implemented to support novel collaborative learning scenarios.

    Integrating Collaborative and Mobile Technologies for Fostering Learning about Negotiation Styles2012In: Proceedings of the 20th international conference on computers in education ICCE 2012, Asia-Pacific Society for Computers in Education, 2012, p. 403-407Conference paper (Refereed)
    Abstract [en]

    The aim of this research is to develop a hands-on spatial geometry learning system to facilitate students’ geometry learning. The system is developed with Duval’s four critical elements of geometry apprehension including perceptual apprehension, sequential apprehension, operational apprehension and discursive apprehension. The system supports senior high school students in the process of spatial geometry problem-solving, allowing them to hands-on manipulate spatial geometry graphics and develop their visualization and mental imagery. In total, 58 participants from different classes were recruited. The experimental group used the hands-on learning system, whereas the control group followed the traditional paper-based approach. The study investigates the effects of the hands-on geometry learning system on students’ perceptual apprehension, sequential apprehension, operational apprehension, overall spatial geometry scores and learning attitude. The results revealed more learning attitude, and higher perceptual apprehension, sequential apprehension, operational apprehension in the experimental group.

    Exploring the multiple dimensions of context: Implications for the design and development of innovative technology-enhanced learning environments2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Technology evolution throughout history has initiated many changes in different aspects of human activities. Learning, as one of the most representative human activities has also been subject to these changes. Nowadays, the use of information and communication technologies has considerably changed the way people learn and collaborate. These changes have been accompanied by new approaches to support learning using a wide range of mobile devices, software applications and different communication platforms. In these technology rich landscapes, the notion of context emerges as a crucial component to be considered for the design and technical implementation of technology-enhanced learning environments. The main research question investigated in this thesis relates to the use of different context instantiations for the design and development of innovative technology-enhanced learning environments.This thesis is a collection of eight papers that describe the results of the research efforts conducted in four different experimental cases during a period of four years. These experiments have been designed and developed as part of two research projects. The theoretical foundations that guided this research were based on the view of context and interaction from a learning theory, human-computer-interaction perspective, as well as dimensional data modelling techniques. Different methodological approaches, (such as action-oriented, design-based research and case study) have been used while investigating the main research question. The main contribution that this thesis offers to the research community is a conceptual context model accompanied by a dimensional data model that can be used as a design tool for embedding learning activities in context. In the four trials that encompass my empirical work, the conceptual model proposed in the thesis guided the design and technical development of the different novel technology-enhanced learning activities. The outcomes of these efforts provided various insights regarding the use of different context instantiations that have implications for the design and development of these environments. This thesis advocates that computational context attributes should be used as metadata descriptors that would potentially promote personalization and interoperability of digital learning content. Content personalization offers opportunities for personalized learning that increases learners’ engagement and eventually could lead to better learning results. Furthermore, the research and industrial community could use the context model developed in this thesis as a guiding tool to promote the creation of new ways to personalize services and technologies.

    Bridging the Gap between Academia and Industry: Lessons Learned from a Graduate IT Professional Development Program2017In: Abstract Book: 2nd Annual International Conference on Engineering Education & Teaching, 5-8 June 2017, Athens, Greece / [ed] Gregory T. Papanikos, Athens, 2017, p. 27-27Conference paper (Other academic)
    Abstract [en]

    The rapid advances of technologies, constantly brings new demands for new skills and expertise of the professionals in IT industry. There is a constant need for people that have in-depth understanding and know how to develop the new innovative services using these new technologies. In these settings, the real challenge is how to find the right persons with the right education in an industry where the in-thing yesterday may be out-of-date tomorrow? To add to this challenge, universities are still “increasingly stove-piped in highly specialized disciplinary fields” (Hurlburt et al., 2010) as well as there is a lack of flexibility for the professionals to have their competences developed. All this points out the great challenges that universities are facing for alignment between academic development within degree curricula and the requirements that industry demands for their specific needs (Falcone et al. 2014). In this research effort we report our experiences from an ongoing Graduate Professional Development Program where we address these challenges through a co-creation process with IT industry based on open innovation. Through this model we bring together research expertise, academic experience and experts from industry in a collaborative process for developing courses to suit the current needs of IT professionals. As an outcome of this process, the course content is tailor-made, as well as everything else in connection, such as: bite-size modules, adjustable pace, open and online educational resources, as well as a flipped classroom approach to teaching. As a result, we have developed and provided so far five courses that have been very well accepted by the IT professional. Thus, in this paper we aim to provide some insights on approaches for facilitating continuous competence development plans for IT professionals within regular university educational offer.

    IoTutor: How Cognitive Computing Can Be Applied to Internet of Things Education2019Conference paper (Refereed)
    Abstract [en]

    We present IoTutor that is a cognitive computing solution for education of students in the IoT domain. We implement the IoTutor as a platform-independent web-based application that is able to interact with users via text or speech using natural language. We train the IoTutor with selected scientific publications relevant to the IoT education. To investigate users' experience with the IoTutor, we ask a group of students taking an IoT master level course at the Linnaeus University to use the IoTutor for a period of two weeks. We ask students to express their opinions with respect to the attractiveness, perspicuity, efficiency, stimulation, and novelty of the IoTutor. The evaluation results show a trend that students express an overall positive attitude towards the IoTutor with majority of the aspects rated higher than the neutral value.

    Collaboration in Context as a Framework for Designing Innovative Mobile Learning Activities2008In: Innovative Mobile Learning: Techniques and Technologies, Information Science Reference, IGI Global, Hershey , 2008, p. 172-196Chapter in book (Other academic)
    Abstract [en]

    In this chapter we describe our continuing efforts related to the design, implementation and evaluation of innovative educational activities supported by ubiquitous computing in the AMULETS (Advanced Mobile and Ubiquitous Learning Environments for Teachers and Students) project. We argue that the design of innovative mobile learning activities should be guided by collaborative learning scenarios in context supported by mobile and ubiquitous technologies in authentic settings. To support this claim, we propose a conceptual framework of collaboration in context that can be used when designing novel mobile learning scenarios. This framework provides the designer with opportunities to tackle the challenges of designing for innovative mobile learning activities. To illustrate our ideas, we present the results of three trials we have conducted with children and adult students since the spring 2006. These mobile learning activities have been designed and implemented using our proposed framework. Working together with the teachers and students gave us the opportunity to design learning activities at authentic locations using meaningful content that has relevance for the school curriculum. The outcome of our efforts suggests that outdoors learning experiences supported by ubiquitous technologies should be combined with learning activities in the classroom to provide learners with meaningful activities.

    Using contextual metadata for enhanced reusability of mobile media objects2009In: Sharing Experiences with Social Mobile Media: Proceedings of the International Workshop in conjunction with MobileHCI 2009, 2009, p. 72-79Conference paper (Refereed)
    Abstract [en]

    Mobile phones are becoming “sensor packed devices”. With this the possibilities for acquiring context has widened. As a result of this, new computing paradigms are emerging. Moreover, mobile phones enable anyone in their possession to be a potential creator of mobile media objects. All this is having impact in the way human activities are performed and has changed the “social mobile media” landscape. The emerging mobile media objects are usually created in an unanticipated way. The challenge in these settings is the interoperability and reusability of these emerging mobile media objects. Since there is no formal control over the creation of these mobile media objects, we consider that use of contextual metadata will be beneficial for addressing the issue of reusability. Inspired from our dimensional model of context we introduce a conceptual scheme for enhancing the reusability of mobile media objects. This scheme is based upon open standards technologies such as XML, XMLSchema, RDF and RDF Schema. To illustrate the usefulness of depicting emerging mobile media objects with contextual metadata, we introduce an experimental scenario in the learning domain.

    A Linked Data Approach for Enriching Emerging Learning Objects with Contextual Metadata2009In: Future Learning Landscapes: Towards the Convergence of Pervasive and Contextual computing, Global Social Media and Semantic Web in Technology Enhanced Learning, 2009Conference paper (Refereed)
    Abstract [en]

    The latest evolution of mobile technologies has increased the possibility for users to generate digital content at any location and time. In this paper, we present our thoughts related to the ability to enhance digital content that emerges when mobile devices are used to support different learning activities. We believe that these emerging learning objects should be enriched with contextual characteristics in a machine interoperable and interpretable manner in order to preserve the meaning, or semantics, of those features. There a number of approaches to tackle this problem but we have chosen to focus on Linked Data as it seems to be a promising solution for enriching these kinds of emerging learning objects with contextual metadata.

    Teaching Distributed Agile Development to Software Professionals: A Flexible Approach2015In: Proceedings of the 2015 European Conference on Software Architecture Workshops (ECSA 2015) / [ed] Matthias Galster, ACM Press, 2015, p. 31-Conference paper (Refereed)
    Abstract [en]

    Software development today is based on a set of Agile approaches in the mindset of Lean. These emphasize the need for team collaboration and communication, rapid feedback and continuous learning. This creates the need for software intensive companies to educate their developers to these ways of working in a manner that allows fast adoption of the acquired skills also in professional capacity. As Agile emphasizes learning, teaching agile development can rely on modern, learner-centric approaches such as situated learning and the idea of a flipped classroom. In this paper we present and reflect upon a case study of two courses of teaching distributed agile development for software professionals based on modern learning theories engaging the learners directly in practice.

    From Architectural Requirements towards an Open Architecture for Web and Mobile Societal Applications2014In: Proceedings of the 1st International Workshop on Inclusive Web Programming - Programming on the Web with Open Data for Societal Applications, ACM/IEEE , 2014, p. 20-23Conference paper (Refereed)
    Abstract [en]

    This paper reflects on our experiences during the last four years regarding the development of a web & mobile application for sustainable environment. After five development cycles our software application has become robust, flexible, and expandable platform. Inspired from this and the needs identified during this process we report our research towards identifying novel architectural approaches that nourish open data and emerging web standards for developing open societal applications. The efforts resulted in an open architecture approach that relies on a set of key characteristics - flexibility, evolvability, customizability, and extensibility. Stressing these characteristics refers to the identified needs of using open standards and reducing development time. The results show that an open architecture approach provides the key ingredients in terms of system integration and data interoperability as well as the ability of the software to grow in terms of new services, devices, and subsystems attached to it, primarily due to the use of open source components and open data standards.

    Towards an Open Architecture Model for Web and Mobile Software: Characteristics and Validity Properties2014In: 2014 IEEE 38th Annual Computer Software and Applications Conference (COMPSAC) / [ed] Chang, CK; Gao, Y; Hurson, A; Matskin, M; McMillin, B; Okabe, Y; Seceleanu, C; Yoshida, K, IEEE Press, 2014, p. 476-485Conference paper (Refereed)
    Abstract [en]

    Proprietary software solutions are extensively deployed through multiple platforms including desktop, web and mobile devices. Such systems are in many cases closed, thus making it difficult for software developers to expand and create additional features to these systems. Recent research in the field of web and mobile technologies indicates that open systems are more successful than those based on proprietary technologies. In this paper, we investigate and analyze existing research related to the notion of open architectures. We conducted a literature survey of the state of the art projects and definitions related to this concept. Our efforts have resulted in a refined definition of the term followed by a conceptual model of an open architecture contextualized within the field of web and mobile software. The model primarily relies on four key characteristics, namely flexibility, evolvability, customizability and extensibility. Furthermore, we present a validation plan based on the GQM approach that further instantiates these characteristics into a set of properties that can serve as metrics.

    Mobile Inquiry Learning in Sweden: Development Insights on Interoperability, Extensibility and Sustainability of the LETS GO Software System2014In: Educational Technology & Society, ISSN 1176-3647, E-ISSN 1436-4522, Vol. 17, no 2, p. 43-57Article in journal (Refereed)
    Abstract [en]

    This paper presents the overall lifecycle and evolution of a software system we have developed in relation to the Learning Ecology through Science with Global Outcomes (LETS GO) research project. One of the aims of the project is to support “open inquiry learning” using mobile science collaboratories that provide open software tools and resources, and participation frameworks for learner project collaboration, mobile data and media capture, publishing, analysis, and reflection. The primary focus of this paper is to report on our technical development, insights and knowledge gained during the past four years. Technical implementations and the prototypes developed in this project have been tested across several educational trials conduced in Sweden and abroad with more than 400 learners. Insights and knowledge gained from these activities verify that learners´ requirements were adequately addressed while satisfying their needs. The outcomes and results of our efforts provided us with a better understanding with regard to which software engineering processes and approaches can be used to address and support the complex requirements that emerge in novel mobile learning scenarios. Thus, the results discussed in this paper provide deeper insights into the importance of properly addressing issues related to interoperability and extensibility in order to develop software solutions to support mobile learning that are sustainable and endurable over time.

    An Interactive Web-based Visualization Tool in Action: User Testing and Usability Aspects2011In: Proceedings 11th IEEE International Conference on Computer and Information Technology, IEEE, 2011, p. 403-408Conference paper (Refereed)
    Abstract [en]

    In this paper, we present our efforts in relation to the evaluation of an interactive web-based visualization tool developed for supporting environmental sciences learning. The tool enables the visualization of different types of geo-tagged content and sensor data collected using mobile devices. It also utilizes APIs that provide multiple visual representations of the data set. These representations allow users to actively interact with graphs, maps, images, and data tables. In order to test the usability, novelty and interactivity of our web-based visualization tool, we have conducted a study involving university students in the field of teaching environmental sciences. The results and analysis of the user testing indicate that the tool’s usability and performance were satisfactory. Outcomes from the user testing have resulted in a number of concrete suggestions for further enhancement and improvements of our visualization tool in relation to application functionality, navigation and interaction.

    Architectural Concepts: Evolution of a Software System across Design and Implementation Stages in Dynamically Changing Environments2012In: Proceedings - International Computer Software and Applications Conference, IEEE, 2012, p. 144-151Conference paper (Refereed)
    Abstract [en]

    This paper presents the design, implementation and the overall lifecycle of a software system that includes mobile and web components and that evolved having the following aspects in mind: (1) System Requirements and Architectural Design, (2) System Implementation and Deployment, and (3) System Assessment and Usability Testing. During the three years of development efforts three software prototypes were implemented utilizing service-oriented approaches. These efforts have been tested with more than 200 users during this period. The outcomes of these activities led to the design and implementation of a system architecture that relies on service- oriented approaches and open standards. Moreover, extensive prototyping with incremental development stages helped to find the balance between the design and implementation of the system while reflecting to rapid changes of software and web- based technologies. Finally, user testing for assessment and testing of the software system were employed in order to cope with the dynamic user requirements. The main outcomes of the efforts described in this paper are presented and summarized in the form of Architectural Concepts that pave the way towards an open, extensible architecture.

    Abstract [en]

    Mobile devices combined with sensor technologies provide new possibilitiesfor embedding inquiry-based science learning activities in authenticsettings. These technologies rely on various standards for data exchange whatmakes the development of interoperable mobile and sensor-based applications achallenging task. In this paper, we present our technical efforts related to how toleverage data interoperability using open standards. To validate the potentialbenefits of this approach, we developed a prototype implementation and conducteda trial with high school students in the field of environmental science.The initial results indicate the potential benefits of using open standards for dataexchange in order to support the integration of various technological resourcesand applications.

    Utilizing Gesture Based Interaction for Supporting Collaborative Explorations of Visualizations in TEL2012In: Proceedings 2012 17th IEEE International Conference on Wireless, Mobile and Ubiquitous Technology in Education, WMUTE 2012, IEEE, 2012, p. 177-181Conference paper (Refereed)
    Abstract [en]

    In this paper, we present our efforts related to the implementation of the prototype that utilizes gesture based interaction for supporting collaborative explorations of visualizations in technology-enhanced learning activities. The prototype enables the visualization of different types of geo-tagged content and sensor data collected using mobile devices. In order to test the novelty and interactivity of our prototype we conducted a user testing study involving university students. The results of this study indicate that participants experienced this prototype as easy to use, with an acceptable overall level of satisfaction. Outcomes from this study show that gesture based interaction become useful when it comes to collaborative explorations of visualizations for supporting learning activities.

    Integrating Mobile, Web and Sensory Technologies to Support Inquiry-Based Science Learning2010In: IEEE WMUTE (International Conference on Wireless, Mobile and Ubiquitous Technologies in Education), IEEE Press, 2010, p. 65-72Conference paper (Refereed)
    Abstract [en]

    Recent advances in mobile, wireless, and sensor technologies provide new possibilities for supporting learning activities that can be spatially distributed and incorporate different physical and environmental sensory data. In this paper, we present our technical efforts in relation to the design and implementation of mobile and web applications that integrate sensory data used to support inquiry-based science learning. In order to test the validity of our solution and its functionality and novelty, we conducted a prototype experiment with high school students in the field of environmental sciences. The initial outcomes presented in this paper point towards the potential benefits of using sensor and mobile technologies with real-time geo-positioned data and visualizations, which may increase students’ engagement, enabling them to conduct scientific inquiries and analyses in new ways.

    Design for Sustainability = Runtime Adaptation U Evolution2015In: Proceedings of the 2015 European Conference on Software Architecture Workshops, ACM Press, 2015, p. 62-Conference paper (Refereed)
    Abstract [en]

    Continuous change changes everything; it introduces various uncertainties, which may harm the sustainability of software systems. We argue that integrating runtime adaptation and evolution is crucial for the sustainability of software systems. Realising this integration calls for a radical change in the way software is developed and operated. Our position is that we need to Design for Sustainability. To that end, we present: (i) the AdEpS model (Adaptation and Evolution processes for Sustainability) to handle and mitigate uncertainties by means of integrating runtime adaptation and evolution, and (ii) a set of engineering principles to design software systems that facilitate the application of the AdEpS model to build sustainable software.

    Context Thinking2008In: Proceedings of 31th Information Systems Research Seminar in Scandinavia, 2008, p. 15-Conference paper (Refereed)
    Abstract [en]

    The advancement of technology has had impact on almost all the aspects of human activities. Learning as one representative of these activities is going through changes as a result. For example, the use of mobile technologies and devices in the learning domain has lead to a magnitude of research, resulting in the field of mobile learning. Context plays a crucial role in any learning activity, and it is impossible to separate the participants, the technology, the activities and its focus, from the environment where it takes place. The focal point have been mostly on the technical side but as in all real-world situations, they exist in an inherently complex setting where social as well as personal implications comes to play an important part in order to reach sustainability. We believe that the lack of sustainability is a result of a barely existing holistic view of the educational situation and claim this complexity can be addressed with an extended view of context thinking. To accomplish this, we suggest a combination of hard and soft approaches, as practitioners need to become competent in context thinking from both perspectives.
