Ubi-Finger: Gesture Input Device for Mobile Use

We propose a novel interface in mobile environment called “Ubi-Finger” that realizes sensuous operations for PDA and information appliances by gestures of fingers. Since gestures are usual methods of non-verbal communications and enables sensuous operations for users, many researches on them carried out especially in the field of Virtual Reality. However most of those existing gesture-input systems are either very expensive or large, and have not been used in mobile environment. In contrast, Ubi-Finger is a gesture-input device, which is simple, compact, and optimized for mobile use. We develop prototype systems, and evaluate how effective our approach works.
