NFC Heroes - Observing NFC Adoption through a Mobile Trading Card Game
- 2012
-
In: Research in the LARGE. ; , s. 19-22
-
Conference paper (peer-reviewed)abstract
- Near-field Communication (NFC) technology finally starts to proliferate on modern smartphones, enabling researchers to conduct researchin the real world. The research question for this work is to learn about the distribution of NFC tags in the wild. As there is, for good and for bad, no central registry or database of NFC tags, we propose a game-based approach to capture the adoption of NFC solutions and technologies.We first report on the development process an NFC-based game. We then present the game logic and implementation, share our experiences from two release cycles on Googles Play Store and finally report on initial results and lessons learned during the whole process.

Update Behavior in App Markets and Security Implications : A Case Study in Google Play
- 2012
-
In: Research in the LARGE. ; , s. 3-6
-
Conference paper (peer-reviewed)abstract
- Digital market places (e.g. Apple App Store, Google Play) have become the dominant platforms for the distribution of software for mobile phones. Thereby, developers can reach millions of users. However, neither of these market places today has mechanisms in place to enforce security critical updates of distributed apps. This paper investigates this problem by gaining insights on the correlation between published updates and actual installations of those. Our findings show that almost half of all users would use a vulnerable app version even 7 days after the fix has been published. We discuss our results and give initial recommendations to app developers.

Research in the large 3.0 : App stores, wide distribution, and big data in MobileHCI research
- 2012
-
In: 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
-
Conference paper (peer-reviewed)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.

BikeSimWS : Workshop on Simulators, Scenarios, and Test Standard for Bicycle Research
- 2023
-
In: Proceedings of MUM 2023 - The 22nd International Conference on Mobile and Ubiquitous Multimedia. - : Association for Computing Machinery (ACM). ; , s. 546-549
-
Conference paper (peer-reviewed)abstract
- Research on cyclists"safety and comfort is a growing topic. Existing works address support systems with novel interaction concepts such as augmented reality but also the design and evaluation of high-fidelity bicycle simulators. Since the field is still in its exploratory phase, there have been few attempts to systematically provide guidance for conducting experiments. For example, there is no consensus on the choice of representative driving scenarios, the proper choice of different bicycle simulators, and measurement standards to systematically compare the results of different studies. With this workshop, we want the community to gather and discuss a roadmap for the future of HCI bicycle research so that these issues can be overcome.

Development and Evaluation of a Motion-Based VR Bicycle Simulator
- 2022
-
In: Proceedings of the ACM on Human-Computer Interaction. - : Association for Computing Machinery (ACM). - 2573-0142. ; 6:MHCI, s. 1-19
-
Journal article (peer-reviewed)abstract
- Bicycle simulators are becoming an increasingly used research tool. However, due to the complex cycling dynamics, these simulators have issues of simulator sickness and perceived realism. A potential method to address these issues could be providing a motion-based tilting function. Some bicycle simulators with tilt functionality have already been presented but still lack a systematic evaluation. In this work, we present a motion-based bicycle simulator without centrifugal force simulation and the results from a user study that compared different tilt modes. N=31 participants completed a study in virtual reality with a strong and a weak tilt mode, as well as a baseline condition without movement. We discovered that weak tilting could significantly improve the cycling realism without decreasing cycling performance and simulator sickness. Furthermore, our research suggests that there is a sweet spot for a tilting function, which facilitates a balance between presence/immersion and simulator sickness
