Hotaka Watarai, Kiyoshi Hoshino (Univ. of Tsukuba)
Abstract (in Japanese) (See Japanese page) 
(in English) We propose a virtual keyboard without installing anything on your hands, make a character input by user’s gesture. We narrow down keys can be entered using the position of the center of gravity of the hand. We detect a typing operation using fingertip positional change in rectangular frame set to each finger. Combination of these, we construct virtual keyboard that can input keys even if hands move in image. We experimented with this system. As a result, skilled person can enter keys high percentage of correct and stable input time. We confirmed non-expert gets used to this system in short time, input time and percentage of correct is improved.
