Outline of Final Research Achievements

We are developing a portable handwriting input device for people of less computer skills. Three microphones of the proposed device catch the frictional sound generated by writing motion of a finger on a palm and the device detects fingertip position continuously from the differences of sound arrival times. We have analyzed the characteristics of frictional sound and devised the separation method from back ground noises. We have also discussed the fast algorithm to calculate sound source position and grouping of sound sources by using their position changes and frequency distributions. After testing by a preliminary experimental equipment and prototype devices repeatedly, we finally made a wearable device and confirmed the device can detect finger motion to some extent.
