Method and system for realizing double-touch communication mode on electronic white board

Abstract

The invention relates to an electronic white board communication scheme, and discloses a method and a system for realizing a double-touch communication mode on an electronic white board. The problemsthat the electronic white board in the traditional technology has single function and touch operation cannot be realized on a projector directly by using the touch function of the electronic white board are solved. The system comprises the electronic white board, the projector and an external computer; a touch signal acquisition module, a touch signal processing module and a UART signal level conversion circuit is arranged in the electronic white board; the touch signal acquisition module converts the acquired touch signal into touch point data and transmits the touch point data to the signalprocessing module; the touch signal processing module converts the touch point data into a corresponding data format according to the current work state fed back by the projector and transmits to theprojector or the external computer; the UART signal level conversion circuit used for converting the level of the communication signal between the electronic white board and the projector; and after the projector or the external computer receives the data transmitted by the electronic white board, the data are converted into actual touch operation.

Description

technical field [0001] The invention relates to an electronic whiteboard communication scheme, in particular to a method and system for realizing a double-touch communication mode on an electronic whiteboard. Background technique [0002] At present, electronic whiteboards are more and more widely used in teaching and conferences. Users can easily operate computers on the electronic whiteboard by using the touch function of the electronic whiteboard. However, the functions of this type of electronic whiteboard are relatively simple, and users cannot use the touch function of the electronic whiteboard to directly perform touch operations on the projector. In other words, after the ordinary electronic whiteboard is separated from the computer, the electronic whiteboard will have no effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a method and system for realizing a dual-touch communication mode on an electr...
