Three-dimensional space-based pointer positioning system and method for demonstration screen

Abstract

The invention provides a demonstration screen pointer positioning system based on three-dimensional space. The demonstration screen pointer positioning system based on the three-dimensional space comprises a sensor module, a processor module and an upper computer. The sensor module comprises a three-axis acceleration sensor, a three-axis gyroscope and a three-axis electronic compass, and is used for gathering acceleration information, angular speed information and geomagnetism component information of a pointer at a certain position in the X-axis, Y-axis and Z-axis perpendicular directions. The processor module is connected with the sensor module through an IIC bus and used for sending instruments to the sensor module and sending gathered information obtained by the sensor module to the upper computer. The upper computer is used for receiving data transmitted by the processor module and processing the data so as to determine direction vectors of the pointer and carry out positioning on the pointer. According to the demonstration screen pointer positioning system based on the three-dimensional space, the size of the system and circuit design difficulty are reduced, and high-precision positioning of the pointer of a large-scale demonstration screen is conveniently carried out. The invention further provides a demonstration screen pointer positioning method based on the three-dimensional space.

Description

technical field [0001] The invention relates to the field of computers, in particular to a three-dimensional space-based demonstration screen pointer positioning system and method. Background technique [0002] Nowadays, people often use a laser pointer to demonstrate when making speeches or group discussions, or use a mouse to locate and operate the pointer; however, when using a laser pointer, the electronic pen function of the presentation software cannot be used, nor It is impossible to perform operations such as page turning; in addition, if a big screen is required for speech or discussion on a large occasion, since the mouse needs a flat working platform, people have to be moved by the mouse when doing large-scale speeches and discussions. bondage. [0003] Based on this, there is indeed a need for improvement in the prior art. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a three-dimensional space-b...
