Typing on the keyboard is one of the commonest activities today, but it is difficult for the people with hand tremor. Because hand tremor featured with the involuntary hand shaking affects precise finger control and hand movements, moreover, most of keyboards have small keys and close arrangement, tremor hands usually fail to precisely type the desired key of the keyboard. In this research, we are first to propose a novel system, which can help hand tremor sufferers correctly type the ordinary physical keyboard without suppressing hand tremor. The proposed system is consisted of two web cameras and a projector, and is assembled around keyboard to provide typing assist. It is designed to recognize one finger typing activities, based on the special characteristics of hand tremor. Two cameras, respectively set at the top and besides of keyboard, track the real fingertip x, y, z positions in image plane. The fingertip positions are real-time virtually stabilized by two low-pass filter (kalman filter and Hysteresis filter) filtering out involuntary tremor component to help system estimate the key that user is desired to type. The estimated keys are visualized by the projector projecting the key projection on the keyboard to present the estimated result for user confirmation. While finger is willing to touch the keyboard, the system will virtually remap all physical keys on the keyboard by the estimated key to make sure correctly input the desired key, no matter what key is actually typed. The previous experiment results have verified that tremor hands typing keyboard with our system can significantly reduce the input error rate, nearly as same as the error input rate of no tremor hand directly typing the keyboard.
