Wireless remote control system and its wireless remote controller

Abstract

The invention provides a wireless remote control device, comprising an action sensor, a moving signal processor and a wireless transmission unit, wherein, the action sensor is used for inducting moving action of the wireless remote control device to generate an inductive signal corresponding to the moving action; and the moving signal processor is used for converting the inductive signal into a moving signal which controls a mouse pointer to move, and transmitting the received moving signal to a computer through the wireless transmission unit to control the motion of the mouse pointer of the computer. The wireless remote control device and a wireless remote control system can control the moving of the mouse pointer of the computer through the action sensor inducing actions of a user, such as waving arms and other body languages, thereby realizing the aim of the indication. Moreover, the wireless remote control device adopts a wireless communication mode to transmit a control signal to the computer, so the user can randomly move within the range of a platform while lecturing; therefore, the wireless remote control device not only can be used conveniently, but also can match the body languages of the lecturer to allow the lecture more vivid. The invention also provides the corresponding wireless remote control system.

Description

technical field [0001] The invention relates to a wireless remote control system and a wireless remote control device thereof, in particular to a wireless remote control system capable of interacting with a computer and a wireless remote control device thereof. Background technique [0002] With the development of computer and projection technology, multimedia teaching and lectures are widely used in work and life. Multimedia teaching and speech refers to the use of multimedia computers to comprehensively process and control symbols, text, sound, video and other media information, to organically combine various elements of multimedia according to the requirements of teaching or speech, and to display them through screen or projector projection. , and at the same time add the cooperation of sound as needed, as well as the human-computer interaction between the user and the computer, to complete the teaching or speech. [0003] Such as figure 1 As shown, it is a schematic di...

Problems solved by technology

However, there is no interaction between the laser pointer 20 and the computer 30. When the user 40 needs to perform computer operations, he has to go back to the computer 30 or need others to perform computer operations such as turning pages up and down for him, which is not conducive to the user 40's speech.
