Background technology
When daily people used keyboard, mouse to come the operational computations machine, the people was limited in face of the desk, made that people's scope of activities is narrow and small! And this single input mode of keyboard+mouse has limited the control ability of people to information.
People realize the infotech of hommization in dream, let exchanging with information world that the people can freely comply with one's wishes.Make the people not only can see prismy information world, can also " touch " it, can arbitrary wish go according to oneself " writing " it, freely control it.Prior art has been made a lot of effort usually aspect following, be used to achieve this end:
1. Wireless Keyboard, wireless mouse.Use Wireless Keyboard, the wireless mouse of short-distance wireless communication technology, the scope of activities when having enlarged people's operating computer to a certain extent.But keyboard volume is bigger, carries, inconvenient operation, and mouse must be attached to an object surfaces when using, and still makes keyboard and mouse can only be sitting in the desk front and operates.And utilize mouse to write, draw very inconvenient.
2. touch screen technology.This technology has realized the computation of visual pattern, lets people break away from the restriction of keyboard and mouse to a certain extent.Cooperate the identification software of specialty, touch-screen can also be realized handwriting input.Touch-screen has developed into the multiple spot touch screen by the single-point touch screen at present.According to its physics form of expression, can be divided into two types:
The one, touch-screen in kind: form by detection part that is installed in the indicator screen front and touch screen controller.When finger or other object touch when being installed in the touch-screen of display front end, the position that is touched is detected by touch screen controller, and delivers to main frame through interface (like RS-232 serial port, USB etc.).That the touch sensible of this scheme has is induction, resistance pressure-sensitive etc.Shortcoming is that touch-screen can not be done very greatly, because its big more resolution is low more, heavy, price is high, and just trouble, the damage more easily more that operate.And this kind scheme is also inconvenient for multiple point touching: must paste screen surface and carry out owing to touch, the screen front number of standing is limited so, and the point that can hold simultaneously above the screen is limited, can block mutually during use, disturb.
The 2nd, wireless positioning type touch screen: mainly contain two types; The first kind is based on infrared, ultrasonic wireless location touch-screen; Its ultimate principle is to place infrared around the display screen or the ultrasonic signal detection array is used for surveying the infrared or ultrasound information that controller sends; Thereby realize the location, still need touch screen when its shortcoming is the person writing, it is all limited that it writes range of control, scope of activities; Second type of wireless location touch-screen that is based on the infrared laser technology; Be the method that adopts optical imagery as the one of which, before camera lens, add and put an optical filter, filter earlier except the light outside infrared; Then image is analyzed, extracted the position of laser point.
For the touch-screen of wireless positioning type, because remote control guides the reference mark very sensitive, the little by little slight vibration of controller will cause the shake of remote controlled point on screen, when user's this phenomenon than remote-controlled operation the time particularly evident! Particularly when the user when using controller to carry out remote keying operation (for example mouse double-click, click etc.), the shake of remote controlled point on screen directly causes dragging in the clicking operation! This makes the operation at that point of user expectation to accomplish.
As shown in fig. 1: for the touch-screen of wireless positioning type, when the user when using controller to carry out the remote keying operation, as shown in Figure 1, the user carries out the mouse-click operation to (101) file.Because remote control guides the reference mark very sensitive, the little by little slight vibration of controller will cause the jitter phenomenon of remote controlled point on screen, thereby becomes (102) with (101) file drags.This phenomenon especially severe during particularly than remote-controlled operation.This makes the operation at that point of user expectation to accomplish.
