RemoteHand: A Wireless Myoelectric Interface

Abstract

Abstract. While myoeletric signals (MES) have long been employed for actuating hand prostheses, their potential as novel input for the interaction with computer systems has received little attention up until now. In this contribution, we present RemoteHand, a system that fosters remote device control through the transmission of myoelectric data over WLAN. This allows to manipulate objects through the user's muscle activity regardless of their physical location. In our setup, a mechanical hand is controlled through electromyographic (EMG) sensors placed over the user's forearm muscles. This approach is compared to a conventional remote device control exercised by a tablet touchpad. The results of our user study show that wireless interaction through myoelectric signals is a valid approach. Study participants achieved interaction speeds equal to those of a standard input method. Users especially value myoelectric input with regard to novelty and stimulation.

Gesture Sensing Using Retransmitted Wireless Communication Signals Based on Doppler Radar Technology

“…This transmitted signal is reflected from the hand and then received by the TX antenna as an echo signal when a gesture is made. This echo signal is coupled to the RF port of the branch-line coupler, as specified by (3).…”

Evaluation of User-Prosthesis-Interfaces for sEMG-Based Multifunctional Prosthetic Hands

“…This work focuses on a methodology to evaluate how different UPIs for transradial upper-limb prostheses influence the user's workload and how user-friendly they are. It is known that several studies have been conducted to evaluate specific prosthetic devices with unimpaired subjects only [19][20][21][22]. The evaluation is subjective, and some assumptions are made regarding the limb-impaired that may not always be accurate.…”
