Embodiment
First embodiment: set forth in the present embodiment and only tiltedly sweep infrared tube touch-screen anon-normal that angle carries out sector scanning to the sector scanning method of scanning at one.
As shown in Figure 2, as an embodiment, the present embodiment first by the positive scan mode touch screen scanning that prior art provides, and obtains the position coordinates (step 1) of the logic touch point on touch-screen, does not certainly also get rid of user and performs this step by other means:
Touch-screen start after, start just to scan, as Fig. 3, shown in, the touch just scanned count no more than 1 time, continue just to scan, according to the fluorescent tube that touch objects is blocked, judge position, touch point, as Fig. 4.According to the fluorescent tube that touch objects is blocked, position, decision logic touch point, as Fig. 5.Its orbicular spot is true touch point, and dotted line is just scanning the light be blocked, and little square is the logical coordinates point (namely may there is the position of true touch point) obtained by just scanning the light that is blocked.
If touching counts more than one, then start tiltedly to sweep: as Fig. 6, determine that the prescan region (step 2) corresponding to angle is tiltedly being swept in this logic touch point according to the position coordinates of the logic touch point scanned and default angle of tiltedly sweeping; The union in the prescan region of each logic touch point is tiltedly swept the current of angle tiltedly sweep region (step 3) as this, as shown in Figure 7; Each logic touch point is tiltedly swept, according to the true touch point (step 4) of tiltedly sweeping in logic touch point described in result identification according to current region of tiltedly sweeping.
Second embodiment: the present embodiment sets forth multiple infrared tube touch-screen anon-normal of carrying out sector scanning when tiltedly sweeping angle to the sector scanning method of scanning.
Multiplely tiltedly sweep angle owing to existing, therefore, need to confirm that the preemphasis that each logic touch point is tiltedly swept corresponding to angle at each sweeps region during step 2 in execution first embodiment.Determine the union in the prescan region of each logic touch point when each tiltedly sweeps angle when performing step 3, and tiltedly sweep the current of angle tiltedly sweep region, as Fig. 8 to Figure 10 as this.Tiltedly swept by step 4 identify true touch point time respectively each tiltedly sweep angle under tiltedly sweep, when tiltedly sweeping after angle all scanned, according to each true touch point tiltedly swept in the scanning result comprehensive descision logic touch point of angle to all.
3rd embodiment: do further to optimize to the second embodiment in the present embodiment.Exist equally in the present embodiment and multiplely tiltedly sweep angle.Different from the second embodiment, as follows to the process of step 4 in execution step 2:
First determine that one of them is tiltedly swept the current of angle and tiltedly sweeps region, under this tiltedly sweeps angle, each logic touch point is tiltedly swept, wouldn't need to judge that other tiltedly sweep the sweep limit of angle, that then tiltedly sweeps angle according to this tiltedly sweeps result exclusive segment error-logic touch point; Using remaining logic touch point as determining next current foundation of tiltedly sweeping region of tiltedly sweeping angle, that is, the union of remaining each logic touch point after getting rid of tiltedly being swept the prescan region of angle at the next one is tiltedly swept the current of angle as the next one and is tiltedly swept region.Tiltedly sweep region remaining each logic touch point is tiltedly swept, according to tiltedly sweeping result debug logic touch point at this.Then using get rid of after logic touch point as the next current definition base tiltedly sweeping region tiltedly sweeping angle, until all angles of tiltedly sweeping all have scanned, or identified all true touch points.All by scanning result exclusive segment logic touch point after the scanning of i.e. each rake angle, to reduce the scanning area of next tilted direction.
The present embodiment is according to revising according to the oblique scanning first carried out or getting rid of logical coordinates point, and the area size of the tilted direction carried out after reduction scanning is not carry out by making the scanning of each tilted direction simultaneously, thus the scanning area of equipment reduces further, reaches better effect.
Embodiment 4, provide the sector scanning device of infrared tube touch-screen anon-normal to scanning in the present embodiment, the function of this device is corresponding with the scan method of the various embodiments described above.This device comprises: computing module, identification module and control module.As shown in figure 11, the logic diagram of the sector scanning device corresponding with the 3rd embodiment is shown.
Embodiment 5: provide infrared pair tube touch screen system in the present embodiment, except comprising the sector scanning device in embodiment 4, also comprise infrared tube, the control accepting control module scans.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within claims of the present invention.
