- Energy and design of energy-feedback are becoming increasingly important in the mobile HCI community. Our application area concerns electric vehicles. We thus depart from home and workplace appliances and address range and energy anxiety caused by short driving distance capabilities and long charging times in mobile settings. While some research has been done on energy management of mobile devices, less has been done on mobility devices like electric vehicles. We explore this topic by letting conventional fuel car drivers reflect on their current driving habits through an exploration tool that we developed. Our results demonstrate three dimensions related to energy availability to consider for design of energy dependent mobility devices and provide explanations on how these dimensions could be utilize in our design through energy visualizations. With this we contributed not only by demonstrating aspects of energy availability and mobility, but also through opening up for new interesting possibilities and inquires in our and possibly other domains.

Research in the large 3.0 : App stores, wide distribution, and big data in MobileHCI research
- 2012
-
Ingår i: MobileHCI'12 - Companion Proceedings of the 14th International Conference on Human Computer Interaction with Mobile Devices and Services. - New York, NY, USA : ACM. - 9781450311052 ; , s. 241-243

Konferensbidrag (refereegranskat)abstract
- Mobile HCI studies are often conducted in a highly controlled environment and with a small convenient sample. The findings cannot always be generalized to the behaviour of real users in real contexts. In contrast, researchers recently started to use apps and other wide distribution channels as an apparatus for mobile HCI research. Publishing apps in mobile application stores and public APIs for mobile services enable researchers to study large samples in their ̀natural habitat'. This workshop continues the successful Research in the Large workshop series held at UbiComp 2010 and 2011. Relevant topics include the design of large-scale studies, reaching target users, dealing with new types of evaluation data, and heterogeneous usage contexts. We seek ways to systematically collect, analyse and make sense of large datasets, potentially in real-time. The goal of this workshop is to provide a forum for researchers and developers from academia and industry to exchange experiences, insights and strategies for wide distribution of user studies towards large-scale mobile HCI research.

A Real-World Study of an Audio-Tactile Tourist Guide
- 2012
-
Ingår i: Proceedings of the 14th international conference on Human-computer interaction with mobile devices and services. - New York, NY, USA : ACM. - 9781450311052 ; , s. 335-344

Konferensbidrag (refereegranskat)abstract
- This paper reports on the in-context evaluation of an audio-tactile interactive tourist guide - one test was done in a medieval city center, and the other was done at an archaeological site. The activity theory framework was used as a perspective to guide design, field-study and analysis. The evaluation shows that the guide allows users to experience an augmented reality, while keeping the environment in focus (in contrast with the common key-hole like experience that on-screen augmented reality generates). The evaluation also confirms the usefulness of extending the vibrational feedback to convey also distance information as well as directional information.

But I Don’t Trust My Friends : Ecofriends - An Application for Reflective Grocery Shopping
- 2012
-
Ingår i: MobileHCI '12 Proceedings of the 2012 ACM annual conference on Human Computer Interaction With Mobile Devices and Services. - New York : ACM Digital Library. - 9781450311052 ; , s. 143-146

Konferensbidrag (refereegranskat)abstract
- The Ecofriends application was designed to encourage people to reflect on their everyday grocery shopping from social and ecological perspectives. Ecofriends portrays the seasonality of various grocery products as being socially constructed, emphasizing subjective dimensions of what it means for a product to be in season, rather than attempting to communicate it as an established fact. It provides the user with unexpected information (news, weather, blog posts and tweets) about the place where the product was grown, and visualises how the product’s popularity shifts throughout the year, among the user’s friends, among chefs and other food experts, and the general public. Key findings from users’ first encounters with the system are presented. In particular, we discuss aspects of trust, information fragments as catalysts, and how several of the participants were challenged by the system’s portrayal of season.
