    Designing and evaluating a digital tool to support online search of Swedish food recipes: facilitating the search process for the users2017Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Searching for food recipes online is a common task for many people in an increasingly digitalised society. Sweden has, as many countries, local recipes, seasonal products, cultural dinners and measurement and weight standards that can differ from other coun- tries. However general searches for Swedish recipes at common search engines can pose several difficulties. For example that users can’t filter the search results by recipes and that there can be difficulties with ambiguous semantic evaluations of the users’ search queries. Aspects considered in this thesis are also how the user search process could be facilitated by using recipe labels and graphical visualisations of the information. The ambition of this thesis is investigate how online recipe search can be made more effi- cient for people looking for Swedish recipes in Swedish.

    An initial user survey with a questionnaire was conducted to understand the po- tential requirements for the development of a tool to support online search of Swedish recipes. More specifically, the survey inquired about users’ current search experience and tried to identify useful search criteria. The results showed that 82.4% of the par- ticipants prefer to search for recipes online via a search engine, compared with other alternatives such as searching at specific recipe sites. The main difficulty the partici- pants experienced with that search approach was that many of the search results were not recipes but other types of search results. Most participants preferred to see more in- formative recipe items in the search results list. However at the same time, some recipe labels that were present were not actually noticed by most participants. The survey also investigated further what information that could be more appropriate to show about the recipes. Based on the outcomes from the survey study, a prototype application was then developed that targets for Swedish recipe search. The purpose of the prototype is to im- plement the search criteria identified from the survey and to provide enhancements. By developing this prototype, the search criteria could be tested by users on the prototype. A second user survey with a questionnaire was then conducted, evaluating the usabil- ity of the prototype. The prototype shows to offer improvements in filtering the search results to only show Swedish recipes, presenting more relevant recipe information and also improvements in visualising the information in the recipes in the search result list.

    Sustainable food systems with ICT?2016Ingår i: 4th International Conference on ICT for Sustainability (ICT4S 2016), Atlantis Press , 2016, Vol. 46, s. 194-201Konferensbidrag (Refereegranskat)
    Abstract [en]

    The food system is burdened by many and severe negative environmental and social impacts. Two of the reasons for the impacts are the increasing scale and globalisation of the food system. ICT has been put forward as a means to enhance sustainability in society, yet the potential for food systems is underexplored. In this paper we review ICT solutions for improved sustainability of food systems, which are used in practice or are discussed as potential solutions. The aim is to identify ICT solutions that can potentially enhance sustainability in the food system. We review mostly scientific literature. The ICT solutions are categorized according to four main purposes of the approach, to 1) efficiency through monitoring and assessment of environmental impact, 2) enhance transparency and traceability in the food system, 3) creating network between actors in the food chains, 4)influence and change food practices. We conclude that there is no coherent research field covering ICT in food systems. The papers reviewed are scattered over several disciplines and scientific journals. We also conclude that there is a predominance of research on monitoring of food production and ransparency and traceability in the food chain. More research is needed that take on holistic approaches and include several parts of the food system.Furthermore, we would also like to see more research onwhat sustainable food systems could be like and how ICT couldsupport and perhaps sometimes hinder such developments.

    Supporting video conference communication using a vision-based human facial synthesis approach2015Ingår i: Proceedings of IEEE SAI Intelligent Systems Conference (IntelliSys), 2015, London: IEEE conference proceedings, 2015, s. 807-812Konferensbidrag (Refereegranskat)
    Abstract [en]

    Facial expressions plays an important role in human communication. In many cases where anonymity is a high priority, the identity of a person needs to be hidden or replaced by another one. Recent advancements in facial expression analysis technology have been used in order to duplicate facial human expressions with an avatar. However, a 3D avatar does not convey the same feeling as a real human face does. This paper documents an exploratory study investigating how vision-based facial analysis can be used to match someones facial expressions and head movements with pre-recorded video segments of another person. As a result of these efforts the identity of that person can be replaced with another person in real-time for videoconference supported communication. The proposed technical solutions have been implemented to support real-t

    An Open Architecture Approach for the Design and Development of Web and Mobile Software2014Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The rapid evolution of web and mobile technologies as well as open standards are important ingredients for developing open software applications. HTML5, affordable electronics, and connectivity costs are some of the trends that drive the web towards an open platform and lead to an increased use of distributed applications. Proprietary software technologies have been extensively deployed throughout multiple platforms, including desktop, web, and mobile systems. Such systems are closed in many cases. Thus, it is rather difficult to expand existing and create additional features for them. Web and mobile software development is fragmented with the existence of multiple browsers and mobile operating systems, that comply differently with web standards. The evolution of web and mobile technologies, coupled with the changes in the deployment environments in which they operate, has resulted in complex requirements that are challenging to satisfy. Additionally, the largest part of the development lifecycle is related to the need to constantly change/modify these software systems within a short-time period. The fact that these systems evolve over time makes it difficult to meet the changing requirements.

    In this thesis, we offer a novel open architecture approach in the area of web and mobile software design and development when dealing with heterogeneous device environments, together with constantly evolving and dynamic requirements. This approach is grounded on our experiences gained during the last four years of project work regarding the development of a web and mobile software system to support mobile inquiry learning. This case served as a testbed for experimentation with heterogeneous device environments. After five development iterations, our software solution is considered robust, flexible, and expandable as a platform. Among others, this was validated with being tested with more than 500 users. The open architecture approach is also grounded on a literature survey of state of the art projects and definitions related to this concept. The outcomes of this thesis show that an open architecture approach is characterized by flexibility, customizability, and extensibility, which are instantiated into a set of properties. The importance of stressing these three characteristics and their properties in the open architecture approach is based on the identified needs of using open source components, using open data standards, and reducing development time. The research efforts in this thesis resulted in a refined definition of an open architecture approach as well as the initial and refined models that are contextualized within the field of web and mobile software. 

    For validation of the research, the Goal Question Metric (GQM) approach is adapted and extended with a layer of Tasks/Activities. The data is collected from the project work mentioned above and three follow-up cases. The results show that the benefits of an open architecture approach can be reflected in terms of: achievement of the software system’s long-term goals; reduced development time; and increased satisfaction of the users. These benefits refer to the possibility to easily adapt emerging technologies and address dynamic changes and requirements. The contributions of this thesis are threefold: (1) for researchers, our open architecture approach could be used to analyze a system from a top down perspective; (2) for developers, it could be used as an approach to identify and address the needs for building an open evolvable system from a bottom up perspective; (3) for domain experts in the technology enhanced learning field, it could be used as a sustainability approach through which to integrate new tools and address complex requirements when designing new educational activities.

    Towards Open Architecture System2013Ingår i: 9th Joint Meeting of the European Software Engineering Conference and the ACM SIGSOFT Symposium on the Foundations of Software Engineering (ESEC/FSE 2013), ACM Press, 2013, s. 731-734Konferensbidrag (Refereegranskat)
    Abstract [en]

    The use of diverse standards while developing web and mobile technologies brings new challenges when it comes to flexibility, interoperability, customizability and extensibility of the software systems. In addition, such systems in most of the cases are closed, thus make the development and customization process for system designers, developers and end-users a challenging effort. All these developments require further research attention. This work addresses these challenges from open system architecture perspective. The proposed approach is based on practical development efforts, and theoretical research including state of the art projects and definitions related to open architectures that we surveyed. The initial results indicate that a combination of service-oriented approaches with open source components and open standard data formats pave the way towards an open, extensible architecture. The core contribution of this research will be (a) an open architecture model and (b) the developed system itself based on the model, and (c) the benefits of applying open architecture approaches throughout the development processes.

    From Architectural Requirements towards an Open Architecture for Web and Mobile Societal Applications2014Ingår i: Proceedings of the 1st International Workshop on Inclusive Web Programming - Programming on the Web with Open Data for Societal Applications, ACM Publications, 2014, s. 20-23Konferensbidrag (Refereegranskat)
    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 Properties2014Ingår i: 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, s. 476-485Konferensbidrag (Refereegranskat)
    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 System2014Ingår i: Educational Technology & Society, ISSN 1176-3647, E-ISSN 1436-4522, Vol. 17, nr 2, s. 43-57Artikel i tidskrift (Refereegranskat)
    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.

    Design for Sustainability = Runtime Adaptation U Evolution2015Ingår i: Proceedings of the 2015 European Conference on Software Architecture Workshops, ACM Press, 2015, s. 1-7, artikel-id 62Konferensbidrag (Refereegranskat)
    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.

    3D Gesture-Based Interaction for Immersive Experience in Mobile VR2016Ingår i: 2016 23rd International Conference on Pattern Recognition (ICPR)Cancún Center, Cancún, México, December 4-8, 2016, Cancun: IEEE Press, 2016, , s. 6s. 2122-2127Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we introduce a novel solution for real-time 3D hand gesture analysis using the embedded 2D camera of a mobile device. The presented framework is based on forming a large database of hand gestures including the ground truth information of hand poses and details of finger joints in 3D. For a query frame captured by the mobile device's camera in real time, the gesture analysis system finds the best match from the database. Once the best match is found, the corresponding ground truth information will be used for interaction in the designed interface. The presented framework performs an extremely efficient gesture analysis (more than 30 fps) in flexible lighting condition and complex background with dynamic movement of the mobile device. The introduced work is implemented in Android and tested in Gear VR headset.

    A unified framework for real-time streaming and processing of IoT data2017Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The emergence of the Internet of Things (IoT) is introducing a new era to the realm of computing and technology. The proliferation of sensors and actuators that are embedded in things enables these devices to understand the environments and respond accordingly more than ever before. Additionally, it opens the space to unlimited possibilities for building applications that turn this sensation into big benefits, and within various domains. From smart cities to smart transportation and smart environment and the list is quite long. However, this revolutionary spread of IoT devices and technologies rises big challenges. One major challenge is the diversity in IoT vendors that results in data heterogeneity. This research tackles this problem by developing a data management tool that normalizes IoT data. Another important challenge is the lack of practical IoT technology with low cost and low maintenance. That has often limited large-scale deployments and mainstream adoption. This work utilizes open-source data analytics in one unified IoT framework in order to address this challenge. What is more, billions of connected things are generating unprecedented amounts of data from which intelligence must be derived in real-time. This unified framework processes real-time streams of data from IoT. A questionnaire that involved participants with background knowledge in IoT was conducted in order to collect feedback about the proposed framework. The aspects of the framework were presented to the participants in a form of demonstration video describing the work that has been done. Finally, using the participants’ feedback, the contribution of the developed framework to the IoT was discussed and presented.

    Blinded by data: The risks of the implicit focus on data in ICT for Sustainability2014Ingår i: ICT4S, Atlantis Press , 2014, s. 148-154Konferensbidrag (Refereegranskat)
    Abstract [en]

    Sustainability is a normative concept, building on ideas such as justice, equity and responsibility, and based on human culture and society. Computers, internet, and the technologies that are central in our network society embed also normative values and are part of a cultural context. But the work looking at computer technologies and sustainability has been mostly oriented towards either calculating the impact of technology or using technology as a tool for solving practical problems. ICT is seen as a neutral system to be used or study, while the more normative aspects are mostly overlooked. This paper explores some of the problems arising from these overlooked normative values, such as focusing only on quantifiable problems while forgetting other aspects that may be as important but not easy to put in numbers, or trusting too much in numbers while hiding assumption and model choices. This paper suggests that more critical reflection on these questions is needed in the research area, as well as developing more connections with existing research on these topics in more traditional disciplines.

    Energy Weight: Tangible Interface for Increasing Energy Literacy2017Ingår i: 2017 Fifth IFIP Conference on Sustainable Internet and ICT for Sustainability (SustainIT 2017), IEEE, 2017, s. 97-99Konferensbidrag (Refereegranskat)
    Abstract [en]

    Increasing energy literacy has been identified as an important topic in order to help people understand their energy use and thereby enabling them to reduce their energy use. We have developed a tangible interface for helping people learn about energy by using wooden blocks as representation of several common cases of energy use. These are then placed on a digital scale connected to a computer which visualizes how many solar panels are required to power these.

    Eco-feedback Visualization for Closing the Gap of Organic Food Consumption2016Ingår i: Proceedings of the  NordiCHI '16: The 9th Nordic Conference on Human-Computer Interaction : Game Changing Design, Association for Computing Machinery (ACM), 2016, artikel-id 75Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents the results of EcoPanel, an eco-feedback visualization created in collaboration with a Swedish food retailer. The visualization uses automatic data gathering to provide consumers with detailed information and long-term trends about their organic food consumption. The results from a five months test with 65 users show an increase in organic purchases compared to the control group, especially for the users who overestimated their percentage of organic food before the test. From the results we point out the possibilities of using visualization as a way of creating insight on behaviors such as food consumption, that are difficult to grasp from individual actions. This insight can be a way of closing the gap between attitudes and actual behavior, helping users that are already aware and willing to change, to perform more sustainable.

    A Web-based Reference Architecture for Mobile Learning: Its Quality Aspects and Evaluation2017Ingår i: 2017 IEEE INTERNATIONAL CONFERENCE ON SOFTWARE ARCHITECTURE WORKSHOPS (ICSAW), IEEE, 2017, s. 232-237Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper discusses the development process and evaluation of a reference software architecture within the field of mobile learning. The architecture implements the workflow of preparation - activity - analysis & reflection of (data collection) activities supported by mobile applications. A number of challenges, like portability, flexibility, or expandability are important to address in mobile learning. To overcome the mentioned challenges in this field, we are proposing a web-based architecture that is supposed to serve as a foundation for the development of software solutions in the field of mobile learning. We discuss scenario descriptions needed for the evaluation and present three implementations in this field that serve as candidate architectures. With the support of those candidates, the reference architecture is proposed. Important system quality attributes are identified and then applied for an evaluation of the architecture using the SAAM method. We conclude by discussing that the proposed architecture does not only fit the field of mobile learning but can also be adapted to a general solution regarding the workflow of: preparation - activity - analysis & reflection of mobile (data collection) applications.

    The (still) unused potential of mobile HTML5 in educational settings2016Ingår i: Proceedings of the 24th International Conference on Computers in Education, Nov. 28-Dec 2, 2016, Bombay, India, Mumbai, India: Asia-Pacific Society for Computers in Education, 2016, s. 392-397Konferensbidrag (Refereegranskat)
    Abstract [en]

    The wide availability of mobile devices like smartphones and tablets among students as well as the included positioning technologies, high definition cameras and other sensors, together with continuous Internet access bring many new opportunities for developing mobile applications supporting learning activities. However, there is an immense fragmentation of operating systems for mobile devices. HTML5 is a promising approach to tackle this challenge. Mobile web applications run within browsers and nowadays, most mobile devices possess a browser that interprets HTML5. Nevertheless, the educational domain seems to ignore this potential and relies on the development of native applications. In this paper, we analyze the opportunities, advantages and drawbacks of developing mobile applications supporting learning activities with HTML5 compared with developing them natively. To illustrate our ideas, we present a couple of showcases that already rely on HTML5, which allow us to further review the development opportunities for mobile HTML5 applications in general, as well as specifically in educational settings.

    Towards a web-based framework to support end-user programming of mobile learning activities2014Ingår i: 2014 IEEE 14th International Conference on Advanced Learning Technologies (ICALT), IEEE Press, 2014, s. 204-208Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper describes the design and development stages of a web-based framework, aiming to support the creation of mobile applications within the context of mobile learning. The suggested approach offers the opportunity to deploy and execute these applications on mobile devices. This web-based solution additionally offers the possibility to visualize the data collected by the mobile applications in a web- browser. Despite previous research efforts carried out in this domain, few of the projects have addressed these processes from a purely web-based perspective. Currently, a prototype of an authoring tool for creating mobile data collection applications is already implemented. In order to integrate and validate this solution in everyday educational settings, we are collaborating with a network of high schools. On the basis of workshops with teachers we will carry out, refinements and requirements for further enhancements will be collected and will be used to guide our coming efforts.

    mLearn4web: A web-based framework to design and deploy cross-platform mobile applications2014Ingår i: Proceedings of the 13th International Conference on Mobile and Ubiquitous Multimedia, New York: ACM Press, 2014, s. 252-255Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents a web-based framework that allows the creation and deployment of mobile learning activities. We present an authoring tool that allows not-technically skilled persons to design mobile learning tasks and deploy them as a web-based mobile application. Since the presented approach is based exclusively on web-technologies, the deployed mobile application can be executed via a mobile browser and therefore is platform independent. Despite previous research efforts carried out in this domain, few of the projects have addressed this course of actions from a purely web-based perspective. Through the latest development of web technologies, mobile applications have access to internal sensors like camera, microphone and GPS and therefore allow data collection within web-applications. In order to validate whether the proposed framework can be applied in educational settings, we conducted a pilot study with experienced teachers and present the results of these efforts in this paper.

    A web-based framework to design and deploy mobile learning activities: Evaluating its usability, learnability and acceptance2015Ingår i: 2015 IEEE 15th International Conference on Advanced Learning Technologies (ICALT), IEEE Press, 2015, s. 88-92Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper discusses the efforts carried out related to the design and development of a web-based framework that allows designing, deploying and executing mobile data collecting applications. Furthermore, it also allows analyzing and presenting the data that is generated during the mentioned process. The fact that the framework is completely web-based provides a platform independent execution of the mobile application on any mobile device with a web-browser. As a result that the whole life-cycle of creating, executing and discussing a mobile learning activity is implemented in pure web-based manner separates this work from similar efforts. In the course of this work, the current state of development of two of the components, the authoring tool and the mobile application is presented. This framework was introduced to teachers in an activity to follow up an initial study. On the basis of a workshop with teachers, we performed an explorative study regarding the technology acceptance and usability of two components of the proposed framework. The results are discussed and analyzed in this paper.

    Toward an Adaptive and Adaptable Architecture to Support Ubiquitous Learning Activities2016Ingår i: Mobile, Ubiquitous, and Pervasive Learning: Fundaments, Applications, and Trends / [ed] Alejandro Peña-Ayala, Springer, 2016, s. 193-222Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    The continuous evolution of learning technologies combined with the changes within ubiquitous learning environments in which they operate result in dynamic and complex requirements that are challenging to meet. The fact that these systems evolve over time makes it difficult to adapt to the constant changing requirements. Existing approaches in the field of Technology Enhanced Learning (TEL) are generally not addressing those issues and they fail to adapt to those dynamic situations. In this chapter, we investigate the notion of an adaptive and adaptable architecture as a possible solution to address these challenges. We conduct a literature survey upon the state of the art and state of practice in this area. The outcomes of those efforts result in an initial model of a Domain-specific architecture to tackle the issues of adaptability and adaptiveness. To illustrate these ideas, we provide a number of scenarios where this architecture can be applied or is already applied. Our proposed approach serves as a foundation for addressing future ubiquitous learning applications where new technologies constantly emerge and new requirements evolve.
