CHI Day 4. Remote CHIBelow are a few additional papers that have relevance to topics of interest that I was not able to see "live."
Exploring User Motivations for Eyes-free Interaction on Mobile Devices - Yi et al.
The authors conducted an exploratory study with four focus groups on eyes-free solutions, and suggest a classification of motivations for eyes-free interaction under four categories (environmental, social, device features, and personal).
Evaluating the Benefits of Real-time Feedback in Mobile Augmented Reality with Hand-held Devices - Luo et al. Modern smartphones make it possible to use AR, by using the phone as an augmented "window on the world." This has obvious advantages for overlaying annotations and information on top of the real world, but raises new challenges for the usability of AR in this context: small screen, occlusion, operation “through a lens”. The authors present a user study of Augmented Reality (AR) in a mobile device, and showed that the optimal system includes AR and real-time feedback (visual). Haptic feedback would be an interesting extension because it does not present the same occlusion problems.
PocketNavigator: Studying Tactile Navigation Systems In-Situ - Pielot et al. The authors report on a large-scale in-situ study of tactile feedback for pedestrian navigation systems, based on usage data collected from a freely available Android navigation app that generates pulse-based tactile feedback during navigation tasks. The authors show that tactile feedback is successfully adopted in one third of all trips and has positive effects on the user’s level of distraction.
Using Shear as a Supplemental Two-Dimensional Input Channel for Rich Touchscreen Interaction - Harrison and Hudson. The authors demonstrate the value of adding shear force as an additional input to augment touchscreen interactions. They created a test device that had a sliding screen and build demonstrations showing the interaction design space opened up by the additional degrees of freedom.
Funneling and Saltation Effects for Tactile Interaction with Virtual Objects - Lee et al. The authors explore the use of funneling and saltation effects for perceiving tactile sensation from a virtual object in an augmented reality setting. Experimental results show solid evidence for phantom sensations from virtual objects with funneling, but mixed results for saltation.
