Study of Gesture Input Interface for Smart Device by Wrist Movement

Abstract

In this research, we proposed a new input method which improved the problem of conventional character input method in smart devices. In this system only the acceleration sensor of smart devices has been utilized. Also, it has a simple and distinctive wrist movement input method. We proposed four types of input operations which are divided depending on whether the operation speed is fast or slow. The average discrimination rate was 90% in case of fast and 70% in case of slow.
