Presents a novel perspective on the mobile search problem using low-cost, incidental information. Demonstrates how other people's queries can provide users with insights into the locations they encounter.
Presents two studies (one static, one mobile) investigating the use of tactile feedback for enhancing touch-screen buttons. Improves performance and reduces workload, even when users are mobile.
This work contributes a comparison of a model of two-thumb text entry with empirical data, modifies it to account for observed behavior, and validates the revised model.
The technique we propose improves the user performance for pointing tasks on mobile phones when no pointing device is available. It favors the development of new mobile applications (eg. 3D)
