A Virtual Technology Aiding for Hand-Impaired Persons

Tremors are one of most common movement disorder symptoms, featured with the involuntary shaking of individual' body parts. They often occur hands and seriously reduce their functions. So that individuals with hand tremors difficultly perform much daily interactions with hands, for instance using tools for eating, touching computer/devices. Traditional approaches that helping trembling hands include "medical approaches", "mechanical approaches", "functional electric stimulation (FES) approaches", and "active approaches", but exist some limitations including body burden, muscle fatigues, and non-application of ordinary device. A way different from traditional approaches-virtual approach is introduced, which allows individuals with completely free trembling hands to preciously interact with ordinary devices meanwhile is no harm and no fatigue to user's hands. This paper reiterates over the scalability of the technology and discusses all hand impaired aided technologies.
