Effect of aesthetics on audio-enhanced graphical buttons

Presented at the 11th International Conference on Auditory Display (ICAD2005)In this paper, two different auditory feedback schemes related to graphical buttons are compared to each other and to a visual- only condition. The results show that aesthetically pleasing auditory design is clearly preferred among the users, and can lead to performance benefits over not only a design with no auditory enhancements, but also a design with aesthetically less pleasing auditory enhancements

Extending the Touchscreen Pattern Lock Mechanism with Duplicated and Temporal Codes

We investigate improvements to authentication on mobile touchscreen phones and present a novel extension to the widely used touchscreen pattern lock mechanism. Our solution allows including nodes in the grid multiple times, which enhances the resilience to smudge and other forms of attack. For example, for a smudge pattern covering 7 nodes, our approach increases the amount of possible lock patterns by a factor of 15 times. Our concept was implemented and evaluated in a laboratory user test (n = 36). The test participants found the usability of the proposed concept to be equal to that of the baseline pattern lock mechanism but considered it more secure. Our solution is fully backwards-compatible with the current baseline pattern lock mechanism, hence enabling easy adoption whilst providing higher security at a comparable level of usability

HCI Outdoors:Understanding Human-Computer Interaction in Outdoor Recreation

HCI in outdoor recreation is a growing research area. While papers investigating systems in specific domains, such as biking, climbing, or skiing, are beginning to appear, the broader community is just beginning to form. The community still seems to lack a cohesive agenda for advancing our understanding of this application domain. The goal of this workshop is to bring together individuals interested in HCI outdoors to review past work, build a unifying research agenda, share ongoing work, encourage collaboration, and make plans for future meetings. The workshop will result in a report containing a research agenda, extensive annotated bibliography, an article about this topic and plans for unifying the community at future meeting

NatureCHI 2017 – The 2nd Workshop on Unobtrusive User Experiences with Technology in Nature

Being in nature is typically regarded to be calming, relaxing and purifying. When in nature, people often seek to be mobile through physical activity such as hiking. But also, nature provides an opportunity for meditative, mindful or inspiring experiences remote from urban everyday life. Mobile Technologies such as sports tracking technologies, electronic tourist guides, mobile phone integrated cameras and omnipresent social media access, have potential to both enhance and disrupt a user’s interaction with and experience of nature. This MobileHCI workshop follows on from the first successful NatureCHI workshop by focusing on the challenges associated with the design of mobile technologies that support unobtrusive interaction in nature

in Conjunction with the 3rd International Conference on Pervasive Computing (Pervasive 2005)

of 13 interesting papers which were reviewed by at least 2 PC members to help the authors to improve their papers for the camera ready version. We would like to thank the authors for their contributions and the organizers of PERVASIVE 2005 for hosting PERMID 2005. Furthermore we would like to thank the Media Informatics Group at the University of Munich and the IST Project Simplicity funded by the EU for their support to publish this workshop record in a printed form. We look forward to the workshop providing a rich environment for academia and industry to foster active collaboration in the development of pervasive mobile interaction devices
