Visualization of hand gestures for pervasive computing environments

Abstract

Visualization method is proposed as an additional feature for accelerometer-based gesture control. The motivation for visualization of gesture control is justified and the challenges related to visualization are presented. The gesture control is based on Hidden Markov Models. This paper describes basic concepts of the gesture visualization and studies how well the developed visualization method can animate hand movement performed during the gesture control. The results indicate that visualization clearly provides information about the performed gesture, and it could be utilized in providing essential feedback and guidance to the user in future gesture control applications.
