Embodiment Construction

[0027] Please refer to FIG. 1 , which is a schematic diagram of a pointing device based on sensing acceleration of the present invention. As shown in Fig. 1, the pointing device 2 based on the sensing acceleration of the present invention will send displacement information to the computing device 1 with the wireless communication component 10, and at least the moving direction and moving distance included in the displacement information can reach the remote computing device 1. the goal of.

[0028] In order to provide and transmit the displacement information, the pointing device 2 of the present invention includes a transceiver unit 21 , a sensing unit 23 , and a processing unit 25 . The processing unit 25 may include a programmable microprocessor integrated circuit, such as an 8051 chip. The bus between the sensing unit 23 and the processing unit 25 can be I 2 C (pronounced as: Isquare C) online interface (Inter-IC, I2C) or analog / digital conversion (ADC) interface, and th...

Abstract

The invention relates to a pointing device based on acceleration sensing, which can operate computer devices or household appliances by means of the displacement information transmitted by the pointing device. The pointing device comprises a transceiver unit, a sensing unit and a processing unit; when acquiring a piece of displacement information sensed by the sensing unit, the processing unit will conduct multiple adjustment over the displacement information, and then send the displacement information to a calculating device through the transceiver unit, finally relevant operations will be carried out. The displacement information is generated by a sensing unit built in the pointing device; the sensing unit detects the motion of the pointing device, changes the relevant axial resistance values, then calculates a new displacement point, and transmits the displacement information by radio. The invention has the advantages of facilitating the operations for users.

Description

technical field [0001] The present invention relates to a pointing device based on sensing acceleration, in particular to a pointing device that senses acceleration by piezoelectric effect. Background technique [0002] For example, computing devices such as computer devices or smart home appliances such as televisions, refrigerators, set-top boxes, washing machines, and air conditioners need to be controlled, especially when these computing devices provide a more complex graphical operation interface (GUI). It requires sophisticated control devices to achieve operational requirements. [0003] At present, control peripheral devices can be roughly divided into mechanical and optical types, such as: mouse, optical trackball, keyboard, wireless mouse, radio optical trackball, radio keyboard, infrared computer remote control, etc. Among them, pointing devices such as mice are most widely used because they are cheap, intuitive and flexible (moving up is equivalent to requiring ...
