Embodiment Construction

[0008] The present invention is a two-point touch bluetooth interactive system, based on infrared positioning detection technology and bluetooth technology, adopts camera, infrared operation pen, combined with projector, bluetooth, computer to realize a new, simple and effective human-computer interaction mode. When the present invention is designed, the main technical indicators include the usable range (m) of the r system, the recognition rate (%) of the r user operation, the response speed (ms) of the r system, the smoothness of the infrared pen operation, and the accuracy of the computer control. Spend. Specifically for the intensity and operation mode of the infrared pen light source, design and verify various interactive methods, and carry out relevant transformations for the inherent shortcomings of traditional electronic whiteboards, improve system stability, intelligence, and system application expansion. Improve the accuracy of user operation recognition, and seek a ...

Abstract

The invention provides a two-point touch Bluetooth interaction system. On the basis of infrared positioning detection technology and Bluetooth technology, when a user operates a screen with an infrared pen, a pen point position is firstly captured by an infrared camera and is then transmitted to a computer via Bluetooth after the pen point position is subjected to coordinate processing; a photography instrument and an infrared operation pen are adopted to be combined with a projector, the Bluetooth and the computer to realize a novel, simple and effective man-machine interaction mode; a coordinate is further converted into a pixel value on a display by software on the computer; and functions of a background service system are invoked to control the computer to realize man-machine interaction. A two-point touch function can be realized, two-point touch is realized by judging track change between two points by the system, an application range is expanded, and interactivity is enhanced. The operating platform of the two-point touch Bluetooth interaction system is free from material restriction, and can be any one plane which is required by the user without requirements on materials.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a two-point touch bluetooth interactive system. Background technique [0002] Traditional blackboard teaching is often unable to meet the requirements of modern students. With the further deepening of teaching reforms, the interaction in the classroom is becoming more and more popular among students, and simple slide shows cannot mobilize the enthusiasm of students. In this case, an interactive system that can adapt to such a large-screen projection needs to be developed urgently. Business meetings also require the interaction and participation of participants. Simple operations on computers are not only cumbersome, but sometimes even ambiguous. [0003] An electronic whiteboard is disclosed in the patent CN 101387930A, a plurality of infrared receivers are distributed along the edge of the panel, wherein each infrared receiver corresponds to an infrared emitter, and the ele...
