Abstract

Typing keyboard is a very common activity, but is difficult for the people with hand tremor. Because hand tremor featured with involuntary hand shaking affects precise hand movements and finger control, and most of keyboards have small keys and close key arrangement, tremor hands usually fail to type the desired key of keyboard. In this paper, we proposed a typing assisted system to support hand tremor sufferers correctly typing with the ordinary physical keyboard under the condition of hand tremor movements. The system includes the novel technologies of finger stabilization and virtual key remapping, which contribute to estimate user's wanted key from finger involuntary shaking and to make sure the key correctly input in the case of finger actually touching the wrong key of keyboard. The experiment results showed that tremor hand typing with the proposed system can significantly reduce the input error rate and the time wasted on correcting error input, comparing with tremor hand typing keyboard directly.
