Abstract

The invention discloses an air mouse low in power consumption. The air mouse comprises a data collecting unit, a wireless emission unit and a control unit. In a working state, the data collecting unit collects spatial gesture data of the air mouse in real time and transmits the data to the control unit. The control unit receives the spatial gesture data from the data collecting unit in real time ad converts the data into corresponding cursor moving information, and the cursor moving information is emitted through the wireless emission unit. Meanwhile, the control unit compares the spatial gesture data which are received in real time with a preset threshold value, and if within preset time period, all the spatial gesture data received by the control unit are smaller than the preset threshold value, the control unit controls the data collecting unit and the wireless emission unit to be disconnected from a power source, and the control unit enters a dormant state from the working state. Standby currents of the air mouse can be greatly reduced, and using time of batteries is prolonged.

Description

technical field [0001] The invention relates to an input device for a computer, in particular to an air mouse with low power consumption. Background technique [0002] An air mouse is an input device for a computer. It can operate the screen cursor like a traditional mouse, but it does not need to be placed on any plane, but can be used directly by shaking or moving in the air. The air mouse needs battery power, but because it is a handheld device, the size and capacity of the battery are often limited when designing. Power management is critical in order to allow users to avoid frequent battery replacements or recharging. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a low-power air mouse, which transmits the space attitude data of the space mouse collected by the data acquisition unit to the control unit for comparison and judgment. All space attitude data received by the control uni...
