Manipulation with fingers in a 3-D physical space

Abstract

Recently, input devices in a three dimensional physical space become popular. However these devices get used only with easy interaction and do not get used for complex interaction yet. In this study, proposes a character recognition technique drawn in a three dimensional physical space considering wearable computing environments. The input device that we developed is worn to a finger. The sensor used the acceleration sensor. The recognition rate is verified through the experiment. As a result of doing various experiments, the recognition rate was 65%. © 2009 Springer Berlin Heidelberg.
