Embodiment Construction

[0019] In order to further illustrate the technical means adopted by the present invention and the achieved effects, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] see figure 1 , is a schematic structural view of the stylus of the present invention. The stylus of the present invention includes a pen holder 101, a reflector 102, a camera 103, a pen head 104 and a communication device 105, the pen holder 101, the reflector 102, the camera 103 and the pen head 104 are connected in sequence, and the communication The device 105 is connected to the camera 103. After the pen head 104 establishes a touch connection with the display or touch screen, the camera 103 obtains the position information of the system cursor on the display or touch screen through the reflector 102. After establishing a communication connection with the operating system, the commu...

Abstract

The invention discloses a stylus. The stylus comprises a pen rod, a reflective mirror, a camera, a pen point and a communication device, wherein the pen rod, the reflective mirror, the camera and the pen point are connected sequentially; the communication device is connected to the camera; the camera obtains position information of a system cursor on a display or a touch screen through the reflective mirror; the communication device sends the obtained position information of the system cursor to an operating system; and the operating system adjusts the position of the system cursor to a position of a touch point. In addition, the invention also discloses a touch point identification method. The stylus can be used to match with a common display to realize touch operations, so that replacement of a display device or hardware modification of the display is unnecessary. In addition, the stylus also can match with conventional touch screens in any size and any type; as the touch device is unnecessary to mount on the display, the size of the display is reduced correspondingly, and no cost is added along with the increase of the size of the display.

Description

technical field [0001] The invention relates to the technical field of touch pens, in particular to a touch pen and a touch point recognition method. Background technique [0002] The current mainstream touch devices have the following forms: infrared touch, the infrared touch screen uses the infrared matrix densely distributed in the X and Y directions to detect and locate the user's touch; optical touch, using two Line-scan cameras on the adjacent corners of the display, the camera detects the movement of any object close to the surface according to the interception of the infrared light source; capacitive touch, the capacitive touch screen is a layer of transparent special metal conductive substance on the glass surface, through Measuring frequency changes can determine the touch position to obtain information; resistive touch, resistive touch screen is basically a structure of film and glass, the adjacent side of the film and glass is coated with nano-indium tin metal ox...
