Space mouse system

Abstract

The present invention relates to a space mouse system. The space mouse system comprises a hand-held transmission system and a receiving system. The hand-held transmission system comprises keys, a radio signal transmitter, an ultrasonic signal transmitter, a triaxial gyroscope, a triaxial accelerometer, a triaxial electronic compass, and a transmission control unit. Output signals of the keys, the triaxial gyroscope, the triaxial accelerometer, and the triaxial electronic compass are input into the transmission control unit and the transmission control unit controls the radio signal transmitter and the ultrasonic signal transmitter. The receiving system comprises a radio signal receiver, a receiving control unit, an output interface, and at least three fixed ultrasonic signal receivers. According to the present invention, the space mouse system combines three-dimensional space information and orientation information, so that an obtained cursor position is located in the junction of the indicator pointed direction and the screen.

Description

technical field [0001] The present invention relates to a mouse, especially a space mouse. Background technique [0002] At present, as large-screen devices are more and more closely connected with the Internet, people begin to choose to use large screens to watch movies, browse the web, play games, communicate and demonstrate, etc. However, how to realize human-computer interaction in a larger indoor space has become the biggest problem, because the traditional mouse, whether it is a wired mouse or a wireless mouse, must move on a plane to realize the control of the cursor. It is very inconvenient to control the big screen. [0003] In indoor teaching and display, laser pointers are usually used to indicate the content on the large screen. At the same time, there are buttons on the laser pointer that can control page turning, which play a great role in PPT presentations, allowing users to leave the desk and have more Large event space. However, the brightness of the ligh...

Problems solved by technology

But at present, both the reflective ranging method and the one-way ranging method have the problem of long response time, and the attenuation of ultrasonic waves in the air is relatively large, which is greatly affected by air temperature and humidity.
