Embodiment Construction

[0036] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0037] The specific implementation method of the present invention is as follows: the hardware in the air mouse control system includes an air mouse and an air mouse controller. The air mouse is held by the user and can move freely. The air mouse controller is fixed in the middle of the upper frame of the display screen, and the position cannot be moved casually. There is no cable connection between the air mouse and the air mouse controller, and the communication and positioning between them all use infrared rays with a wavelength between 850nm and 950nm. Only one air mouse controller is needed, that is, it can form a one-to-one air mouse system with one air mouse, and can form a one-to-many air mouse system with multiple air mice. The one-to-one system can only provide the coordinates and button information of one air mouse, which is suitab...

Abstract

The invention discloses an air mouse. The air mouse comprises a shell and an operation control unit arranged in the shell, and the operation control unit is connected with an infrared communication receiver for the mouse, an infrared positioning receiver, silicon photocells, an infrared emitter for the mouse and battery. An air mouse control system comprises a one-to-one control system and a one-to-many control system. A control method includes firstly, emitting periodical infrared pulse signals, enabling every air mouse to receive the infrared pulse signals at the same time, computing coordinate values, sequentially emitting infrared polling signals to every air mouse after every air mouse is processed to request that every air mouse sends coordinates and key state data thereof, using a microcontroller to start to monitor the infrared communication receiver, and receiving the coordinates and the key state data sent by every air mouse; using the microcontroller to summarize all the coordinates and the key state data after every air mouse is polled, and sending summarized data to a computer mainframe through a USB communication protocol. The air mouse is low in cost, high in precision, easy to use, more precise in positioning and suitably applied to various environments.

Description

technical field [0001] The invention belongs to the technical field of computer control, and in particular relates to an air mouse, its control system and an infrared positioning method which realizes the control function through infrared direction finding and infrared coding communication. Background technique [0002] The air mouse is an input device that operates the screen cursor like a traditional mouse, but it does not need to be placed on any flat surface, and can be used directly by shaking it in the air. Freedom and convenience are its characteristics. For example, it can be used as a briefing pen in the office field, so that people who make PPT presentations no longer need to sit on the conference table and fiddle with the computer, and can use remote control to realize functions such as mouse operation and page turning; entertainment at home It can be used in the living room with a TV or HTPC, and it becomes a "tool for lazy people". [0003] According to the nov...
