We built an acoustical telepresence robot named TeleHead, which has a user-like dummy head and whose movement is synchronized with the user's head movement in real time. An accurate-shape user-like dummy head improves sound localization accuracy, but making an accurate-shape user-like dummy head for all users is not realistic. There have been many efforts to simplify dummy heads without head movement...
By using conventional MEMS processes, we have successfully developed a high accuracy and easily controllable deformable mirror with simple structure. Furthermore, we have obtained a reflective film of low stress which was a challenge.
