A development of the feedback method which the texture of the grasped object to the artificial hand user.

Abstract

In recent years, the number of artificial hand users has increased, while the user do not feel the touch like healthy person using their hand. There are many types of artificial hands which are operated by EMG. Most of them are used some EMG signals that are measured form user's forearm. Because muscles in forearm dominate hand and finger motions, we can estimate various hand motions using these signals. The mechanism that can display power according to each hand motions to the user is experimentally developed. In this paper, we propose the method that can display texture of the object touched by a user of the artificial hand by using the vibration in a speaker.
