    Using Mobile Augmented Reality to Facilitate Public Engagement2017Ingår i: Extended Papers of the International Symposium on Digital Humanities (DH 2016) / [ed] Koraljka Golub, Marcelo Milrad, CEUR-WS , 2017, Vol. 2021, s. 99-109Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents our initial efforts towards the development of a framework for facilitating public engagement through the use of mobile Augmented Reality (mAR), that fall under the overall project title "Augmented Reality for Public Engagement" (PEAR). We present the concept, implementation, and discuss the results from the deployment of a mobile phone app (PEAR 4 VXO). The mobile app was used for a user study in conjunction with a campaign carried out by Växjö municipality (Sweden) while exploring how to get citizens more engaged in urban planning actions and decisions. These particular activities took place during spring 2016.One of the salient features of our approach is that it combines novel ways of using mAR together with social media, online databases, and sensors, to support public engagement. In addition, the data collection process and audience engagement were tested in a follow-up limited deployment.The analysis and outcomes of our initial results validate the overall concept and indicate the potential usefulness of the app as a tool, but also highlight the need for an active campaign from the part of the stakeholders.Our future efforts will focus on addressing some of the problems and challenges that we have identified during the different phases of this user study.

    Change your Perspective: Exploration of a 3D Network created with Open Data in an Immersive Virtual Reality Environment using a Head-mounted Display and Vision-based Motion Controls2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Year after year, technologies are evolving in an incredible rapid pace, becoming faster, more complex, more accurate and more immersive. Looking back just a decade, especially interaction technologies have made a major leap. Just two years ago in 2013, after being researched for quite some time, the hype around virtual reality (VR) arouse renewed enthusiasm, finally reaching mainstream attention as the so called head-mounted displays (HMD), devices worn on the head  to grant a visual peek into the virtual world, gain more and more acceptance with the end-user. Currently, humans interact with computers in a very counter-intuitive two dimensional way. The ability to experience digital content in the humans most natural manner, by simply looking around and perceiving information from their surroundings, has the potential to be a major game changer in how we perceive and eventually interact with digital information. However, this confronts designers and developers with new challenges of how to apply these exciting technologies, supporting interaction mechanisms to naturally explore digital information in the virtual world, ultimately overcoming real world boundaries. Within the virtual world, the only limit is our imagination.

    This thesis investigates an approach of how to naturally interact and explore information based on open data within an immersive virtual reality environment using a head-mounted display and vision-based motion controls. For this purpose, an immersive VR application visualizing information as a network of European capital cities has been implemented, offering interaction through gesture input. The application lays a major focus on the exploration of the generated network and the consumption of the displayed information. While the conducted user interaction study with eleven participants investigated their acceptance of the developed prototype, estimating their workload and examining their explorative behaviour, the additional dialog with five experts in the form of explorative discussions provided further feedback towards the prototype’s design and concept. The results indicate the participants’ enthusiasm and excitement towards the novelty and intuitiveness of exploring information in a less traditional way than before, while challenging them with the applied interface and interaction design in a positive manner. The design and concept were also accepted through the experts, valuing the idea and implementation. They provided constructive feedback towards the visualization of the information as well as emphasising and encouraging to be even bolder, making more usage of the available 3D environment. Finally, the thesis discusses these findings and proposes recommendations for future work.

    Change Your Perspective: Exploration of a 3D Network Created from Open Data in an Immersive Virtual Reality Environment2016Ingår i: ACHI 2016: The Ninth International Conference on Advances in Computer-Human Interactions / [ed] Alma Leora Culén, Leslie Miller, Irini Giannopulu, Birgit Gersbeck-Schierholz, International Academy, Research and Industry Association (IARIA), 2016, s. 403-410Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper investigates an approach of how to naturally interact and explore information (based on open data) within an immersive virtual reality environment (VRE) using a head-mounted display and vision-based motion controls. We present the results of a user interaction study that investigated the acceptance of the developed prototype, estimated the workload as well as examined the participants' behavior. Additional discussions with experts provided further feedback towards the prototype's overall design and concept. The results indicate that the participants were enthusiastic regarding the novelty and intuitiveness of exploring information in a VRE, as well as were challenged (in a positive manner) with the applied interface and interaction design. The presented concept and design were well received by the experts, who valued the idea and implementation and encouraged to be even bolder, making more use of the available 3D environment.
