Device for processing optical control information

Abstract

The embodiment of the invention discloses a device for processing optical control information, which comprises an optical display (104), a common laser pen (102) and an information processor (103), wherein the information processor (103) recognizes light spots emitted by the laser pen (102), performs corresponding processing according to the recognition result and finally transmits the processing result to other devices such as the optical display and the like. By using the device and a method of the invention, a user can realize the remote control of information input, convenient writing and information control by only using the common laser pen.

Description

technical field [0001] The invention relates to an optical control information processor, in particular to a laser spot control information processing device. Background technique [0002] When everyday people use keyboards and mice to operate computers, people are limited in front of the table, which makes people's range of activities narrow! And the single input method of keyboard+mouse limits people's ability to manipulate information. [0003] People are dreaming of realizing humanized information technology, so that people can freely communicate with the information world. People can not only see the colorful world of information, but also "touch" it, "write" it as they like, and manipulate it freely. The prior art usually makes a lot of efforts in the following aspects to achieve this goal: [0004] 1. Wireless keyboard, wireless mouse. Wireless keyboards and wireless mice using short-distance wireless communication technology have expanded the range of activities ...

Problems solved by technology

The disadvantage is that the touch screen cannot be made very large, because the larger it is, the lower the resolution, the bulkier, the higher the price, and the more troublesome it is to operate, the easier it is to damage

[0007] The second is wireless positioning touch screen: there are two main types. The first type is wireless positioning touch screen based on infrared and ultrasound. The basic principle is to place infrared or ultrasonic signal detection arrays around the display screen to detect infrared or ultrasonic signals emitted by the controller. The disadvantage is that people still need to touch the screen when writing, and their writing control range and activity range are limited; the second type is a wireless positioning touch screen based on infrared laser technology, which generally uses optical imaging. Add a filter in front of the camera lens to filter out light other than infrared, and then analyze the imaging image to extract the position of the laser point

However, as mentioned earlier, the current way people control information is mainly keyboard+mouse, which is in a single form, and it is difficult to achieve universal access by using touch screen technology.
