Recently, researchers investigating human machine interfaces (HMI) have been trying to create easier to use interfaces by taking advantage of the communication and manipulation skills natural to human beings. HMIs with a direct sensing feature can be developed for a wide range of applications. However, because of the inherent limitation posed by input devices such as the mouse, keyboard and touch-sensitive panels, it is not possible to utilize the abundant forms of natural human expressions. In this paper, an effective non-contact technique for the measurement of the human hand motion with application to HMI has been reported. We propose a method for detecting the motion f a subject's hand with respect to a given measurement electrode by measuring the current generated due to the change in the capacitance between a subject's hand and the measurement electrode. This method effectively describes the behavior of the waveform of the induced current.
