A natural hand gesture system for people with brachial plexus injuries

Abstract

This paper focuses on a design case study of a natural hand gesture system for users with intact motion control of the metacarpophalangeal joint and thumb basal joint of the hand after brachial plexus injuries. The lexicon of hand gestures had eight entries and was demonstrated to be natural and ergonomic with the limited hand motions. A cooperative multi-cue system was proposed for the key hand posture recognition of the proposed hand gestures. We utilized the designed system into a remote smart car control and electric wheelchair control. Experimental a results demonstrated the robustness and potential feasibility of the system in human-computer interaction for the proposed users.
