Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0076] First, let me introduce the working principle of the multi-light touch control device:

[0077] The user controls different light sources to emit light points with different optical characteristics to the display screen; the multi-light point touch device records a unique identity for each light point according to the different optical characteristics of each light point; the multi-light point touch device It can recognize different light points on the display screen, as well as their characteristics of movement, on-off and so on; by corresponding the movement and on-off characteristics of light points to the cursor movement and click events of the information system, the multi-light point touch device can control each The dot ...

Abstract

The embodiment of the invention discloses a multi-spot touch control device based on an optical principle, and particularly a multi-spot touch control device using laser light spots. The device comprises a first optical controller (101) and a second optical controller (102), an information processor (103) and an optical monitor (104). A user controls the different optical controllers (101, 102) to emit a first emit light spot (105) and a second emit light spot (106) having different optical characteristics to an optical display screen (104); a multi-light spot touch device can identify different light spots on the optical display screen (104), and the characteristics such as movement and blinking of the light spots; and the device realizes that a plurality of light spots are input as multi-spot touch control by corresponding the characteristics of the movement and the blinking of the plurality of light spots to a plurality of cursor movement and clicking events. The device and the method can enable the user to conveniently achieve multi-spot touch in a large range, and all the light beams can be penetrated and mutually have no any interference to show excellent control speed and fluency.

Description

technical field [0001] The invention relates to a multi-light point touch control device, in particular to a device for multi-point touch control using laser light points. Background technique [0002] A traditional multi-touch screen consists of a detection component and a touch screen controller installed in front of the display screen. The touch sensors adopted include electromagnetic induction, resistive pressure and so on. When a finger or a special touch pen touches the touch screen installed on the front of the display, the touched position is detected by the touch screen controller and sent to the host through the interface (such as RS-232 serial port, USB, etc.). [0003] This solution is not convenient for multi-touch: [0004] For small touch screens, use your finger or stylus to tap on the screen surface. Since the touch controllers (touch pen holder or fingers) cannot penetrate each other, when two touch points are close, the touch pens (or fingers) will bloc...
