Problems solved by technology
Furthermore, in order to improve the interactivity of the infrared electronic whiteboard in use, it is required to support multi-touch input, and multi-touch input is often difficult to be properly compatible with the recognition processing system of the infrared electronic whiteboard, and the multi-touch function is often difficult to realize. At the same time, it is difficult to have both sampling speed and function, which makes the sensitivity of the whiteboard in a poor state

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0027] As shown in Figure 1 to Figure 5:
[0028] The processing method of multiple contacts of the infrared electronic whiteboard is to set the infrared tube and the bottom processor on the infrared electronic whiteboard, arrange the infrared tubes on the four sides of the infrared electronic whiteboard, one of the two opposite sides is the transmitting tube 1, the other side is the receiving tube 2, and the infrared tube The surface of the infrared electronic whiteboard is continuously scanned from the transmitting tube 1 to the receiving tube 2. Once an object 3 stays or slides over a certain coordinate point on the surface of the infrared electronic whiteboard, the output of the receiving tube in the X and Y directions of the coordinate point changes, and the underlyin...

The invention relates to an application of the infrared technique, in particular to a process method of an infrared electronic white board which can precisely realize multiple contacts. When multiple contacts are generated, objects stay or slide on two coordinate points on the surface of the infrared electronic white board, a substratum processor gains X and Y coordinates of the two coordinate points and compares respective areas which are occupied by the two objects, and the substratum compares the relative distances, and distinguishes the mode of current multiple contacts according to the compared values, and then sends command and erases the infrared electronic white board and writes on the infrared electronic white board. The invention can be applicable to various input situations of multiple contacts, improves interchangeability of the infrared electronic white board in the application, and enables the infrared electronic white board to support the input style of the multiple contacts, and simultaneously, a computer is used to share calculating pressure of the substratum processor, which stabilizes the input of multiple-contact styles and compatibility of the infrared electronic white board.
Description
technical field [0001] The invention relates to the application of infrared technology, in particular to a processing method for multiple touches of an infrared electronic whiteboard capable of accurately realizing multiple touches. Background technique [0002] Infrared electronic whiteboard adopts infrared technology. Infrared technology works by multiple pairs of infrared emitting and receiving tubes. A simple infrared detection method can be obtained by using infrared emitting tubes and infrared receiving tubes (referred to as infrared pairing tubes) of the same wavelength. Any object that blocks light can be used as a pen, as long as there is an object blocking the connection between the infrared pair tubes, the received signal will drop sharply. In the existing infrared electronic whiteboards, infrared tubes are densely distributed on the four sides of the electronic whiteboard. Among the two opposite sides, one side is a transmitting tube, and the other side is a rece...
