Description
[affiliated technical field]
The present invention relates to a kind of method of track identification, particularly to method by identification dynamic trajectory control cursor, operating window.
[background technology]
Along with the continuous development of computer hardware technology, people use the mode of mouse that change has also taken place on computers.When particularly playing computer game, more people begin to use rocking bar, bearing circle, and the high precision mouse is played games.On market, occurred at present a kind of be used for computer game can come analog mouse to control the product that screen mouse moves with sensor by reflection spot.This product is a kind of feedback assembly that positions according to feedback point.But, the light around when using this existing product, will reducing as much as possible, because this existing product can be gathered feedback light from device and user's background behind, faint light will bring the inaccurate trouble in location.Simultaneously, because existing product mainly is moving at the analog mouse cursor of game design, therefore, the user can not simulate the action of clicking the mouse function key by this product, when cursor moved to the appointed place, the user still need wait the operation of finishing next step by the hot key on mouse, game paddle or the keyboard.Like this, will make and also need to cooperate the peripheral hardware together could complete operation when the user uses this product.
In addition, be in the patent documentation of CN1357862A at the Chinese patent publication number, disclosed a kind of cursor vision point choosing method and device of form.This device includes an Image intake device and a computer, links up by interface and this Image intake device; This method includes the pupil of obtaining the user information that relatively moves, and dynamically adjusts the relative position relation between the form of this cursor and computer.It is that technical scheme can allow the computer user need not rolling mouse can at random operate cursor to move the inconvenience that can avoid hand to operate back and forth between mouse and keyboard that this patent documentation discloses.But the technical scheme that this patent documentation disclosed is to move positioning cursor according to user's pupil.When operating, catch moving of eye pupil, like this, certainly will will limit the activity of user's eyes, cause the fatigue of user's eyes, bring the inconvenience in the use by image-pickup device.Similarly, the technical scheme that this patent documentation disclosed is also just controlled moving of cursor, and can not finish other function operations.
[summary of the invention]
The object of the present invention is to provide a kind of method of discerning, operating cursor, form by the dynamic trajectory that obtains external light source, it has easy to use, comfortable advantage.
Another object of the present invention provides a kind of method of discerning, operating cursor, form by the dynamic trajectory that obtains external light source, and it has, and processing speed is fast, operation cursor and the sensitiveer advantage of form.The present invention also aims to solve and to have controlled the problem that cursor moved and can't further realize function key operation in the existing product.
Concrete technical scheme of the present invention is as follows:
A kind of method by identification dynamic trajectory control cursor, operating window provides the light source and the image acquisition unit that produce dynamic trajectory, may further comprise the steps:
