    • A finger pointing apparatus is disclosed. In one aspect the finger pointing apparatus includes at least one pressure sensor fixed on a hand for triggering a corresponding electromagnetic wave transmitter to transmit electromagnetic wave when pressure is produced by a finger contacting an external object. In another aspect, the finger pointing apparatus includes at least one electromagnetic wave transmitter connected with a corresponding pressure sensor and fixed on the hand for transmitting electromagnetic wave to all electromagnetic wave receivers when pressure is detected by the pressure sensor. In one aspect, the finger pointing apparatus includes at least two electromagnetic wave receivers arranged at fixed positions with respect to each other for receiving electromagnetic wave from the at least one electromagnetic wave transmitter and transmitting received electromagnetic wave to a microprocessor. In another aspect, the finger pointing apparatus includes a microprocessor for receiving electromagnetic wave from the electromagnetic wave receivers, calculating coordinate values of a position pressed by the finger from electromagnetic wave from different electromagnetic wave receivers and outputting the coordinate values.
    • 公开了一种手指指向装置。 在一个方面,手指指向装置包括固定在手上的至少一个压力传感器,用于当由手指接触外部物体产生压力时触发相应的电磁波发射器传输电磁波。 另一方面,手指指示装置包括至少一个与对应的压力传感器连接的电磁波发射器,并固定在手上,用于当由压力传感器检测到压力时将电磁波传输到所有的电磁波接收器。 一方面,手指指示装置包括布置在彼此固定位置的至少两个电磁波接收器,用于接收来自至少一个电磁波发射器的电磁波,并将接收的电磁波发射到微处理器。 在另一方面,手指指示装置包括微处理器,用于从电磁波接收器接收电磁波,计算由手指按下的来自不同电磁波接收器的电磁波的位置的坐标值并输出坐标值。
