Description
Technical field
The present invention relates to a kind of indicator device and trajectory smoothing method, particularly relate to a kind of trajectory smoothing method that has the indicator device of smooth trajectory function and be applicable to indicator device.
Background technology
In various computer peripheral equipments, the mouse person of being to use is one of the computer peripheral equipment of normal use, be mainly used to the computer input unit as a kind of form, be specially adapted to the application on the visual pattern, therefore mouse has become indispensable input tool at present.At present more common mouse is divided into two kinds of idler wheel mouse and optical mouse.Idler wheel mouse uses the physical construction of the roller microcontroller chip of arranging in pairs or groups again to handle displacement signal.The cmos image sensor that the optical mouse utilization has an optical guidance function replaces the physical construction of roller, and the microcontroller chip of arranging in pairs or groups is handled displacement signal.When mouse moves, the displacement of its time per unit can export computing machine in regular turn to, because the displacement of mouse is the result that the image sensor through the physical construction of idler wheel mouse or optical mouse quantizes, but not actual continuous path, therefore, even the track that mouse moves does not all have vertical line segment, might make that in through the process that quantizes vertical line segment occurs, it is former because angle too small can't detect, and the both direction of two-dimensional coordinate has error or the like when quantizing.
Trajectory diagram when Fig. 1 moves for conventional mouse.Conventional mouse directly as output valve, exports the displacement input value of institute's sensing to computing machine in regular turn.As shown in Figure 1, I is a starting point, and each displacement input value is the displacement with respect to last position, is input value P in regular turn
11(1,0), input value P
12(0,2), input value P
13(2,0), input value P
14(1,0), input value P
15(0,3), input value P
16(5,0) and input value P
17(0,5).When these input values by directly as output valve, and when exporting on the computer screen in regular turn, the track that shows on the screen just as shown in Figure 1, for zigzag and have the lines of right angle, many places turnover, this is not gratifying output result.
Summary of the invention
In view of this, purpose of the present invention just is to provide a kind of indicator device, in order to carry out the smooth trajectory function, comprising: the track treatment circuit, receive digitized displacement, and add up program to produce the displacement accumulated value in order to execution; Wherein,, then export described displacement accumulated value,, and carry out replacement process with the described displacement accumulated value of resetting in order to the pointer on the level and smooth mobile display device to treating apparatus when described displacement accumulated value satisfies when pre-conditioned.
The present invention more provides a kind of trajectory smoothing method, is applicable to indicator device, comprises the following steps: to provide the track treatment circuit, receives digitized displacement, carries out the program that adds up to produce the displacement accumulated value; Judge whether described displacement accumulated value satisfies pre-conditioned; And described pre-conditioned as if satisfying, then export described displacement accumulated value to treating apparatus, in order to the pointer on the level and smooth mobile display device, and carry out replacement process with the described displacement accumulated value of resetting.
