摘要:
A two-dimensional position detection unit takes the procedure so that two ultrasonic speakers attached to both end portions of a wrist outputs an ultrasonic wave while five ultrasonic microphones attached to fingertips detect it. The two-dimensional position detection unit measures time difference from output to detection of the ultrasonic wave. Then, the two-dimensional position detection unit calculates a two-dimensional position of each fingertip attached with the ultrasonic microphones based on the time difference. Further, an action detecting unit detects an occurrence of a predetermined change in acceleration outputted by the acceleration sensors attached to each fingertip and having sensitivity in the direction vertical to a palm of a hand (x-y plane). Then, the action detecting unit recognizes an action of hitting a keyboard.

二维位置检测单元采用这样的过程,使得附接到手腕的两个端部的两个超声波扬声器输出超声波,同时附接到指尖的五个超声麦克风检测它。 二维位置检测单元测量从输出到检测超声波的时间差。 然后,二维位置检测单元基于时差计算安装有超声麦克风的每个指尖的二维位置。 此外,动作检测单元检测由附接到每个指尖的加速度传感器输出的加速度的预定变化的发生,并且在垂直于手掌(x-y平面)的方向上具有灵敏度。 然后,动作检测部识别敲击键盘的动作。
