Abstract
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 recei…
