Embodiment Construction

[0035] see figure 1 As shown, the optical touch positioning system 100 of the present invention is used to identify the position of a touch point on a touch surface 10 to perform corresponding display or action. A preferred embodiment mainly includes an optical touch locator 2 and an electronic device 3 . The optical touch locator 2 can be arranged in the pen shaft to form an optical touch pen 4, which is used to obtain such as figure 2 A partial image on a touch surface 10 is shown. A plurality of positioning points P arranged in a matrix are printed on the touch surface 10, and these positioning points P define a plurality of touch areas T, for example figure 1 100x50 (=5000) touch areas T are shown. A plurality or at least one information point I is printed in each touch area T, wherein OID code or other optical codes can be used to imply a predetermined corner of the touch area T, such as the position information of the upper left positioning point. And the position i...

Abstract

The present invention provides an optical touch locator method, system and optical touch locator, which are applied to an optical touch locator. The method enables the optical touch locator to obtain a partial image of a touch surface, in which the partial image It includes a plurality of positioning points and information points, and the positioning points define multiple touch areas, each touch area includes at least one information point, and the information points imply the position of the positioning point at a predetermined corner of the touch area For position information, the optical touch locator determines which touch area a central point of the partial image is located in, and interprets the information point in the touch area to obtain the position information of the positioning point in the predetermined corner.

Description

technical field [0001] The present invention relates to a touch identification method, in particular to an optical touch positioning method related to optical coding technology. Background technique [0002] Optical Identification (OID) technology can hide digital information in a printed matter through ink printing, and read the hidden digital information in the printed matter through the optical and image processing technology of an optical identification pen. For example, the existing point reading pen sold on the market can point and read the transparent OID code printed under a pattern with OID technology on the page of a book, and compare the read OID code, and the point reading pen will issue a corresponding voice or music for teaching or entertainment purposes. In addition, there is no application of the OID technology in the field of touch positioning. Contents of the invention [0003] Therefore, the purpose of the present invention is to provide an optical tou...
