Abstract: An air mouse system is described. The air mouse is configured to periodically transmit RF signals in order to trigger a plurality of ultrasonic transmitters arranged on a television. The ultrasonic transmitters transmit ultrasonic signals when being triggered by the RF signals from the RF trigger. An ultrasonic receiver receives the ultrasonic signals. A processor calculates a location of the air mouse with respect to the ultrasonic transmitters based on time differences of the ultrasonic signals transmitted by the ultrasonic transmitters arriving at the ultrasonic receiver. A series of locations of the air mouse forms a motion trail of the air mouse and the air mouse transmits the motion trail to the television wirelessly. The motion trail is projected as a cursor trail on the television screen by the television, to control the cursor on the television screen by virtue of the motion of the air mouse.

Abstract translation: 描述了空中鼠标系统。 空中鼠标被配置为周期性地发送RF信号以便触发布置在电视机上的多个超声波发射器。 当由RF触发器的RF信号触发时，超声波发射器发射超声波信号。 超声波接收器接收超声波信号。 处理器基于到达超声波接收器的超声波发射机发送的超声波信号的时间差，计算空中鼠标相对于超声波发射器的位置。 空中鼠标的一系列位置形成空中鼠标的运动轨迹，空中鼠标将运动轨迹无线地传送到电视机。 运动轨迹由电视机在电视屏幕上投影为光标轨迹，借助于空中鼠标的运动来控制电视屏幕上的光标。
