Description
Technical field
The present invention relates to a kind of method for compensating signal, and be particularly related to a kind of compensation method of touching signals.
Background technology
Along with scientific and technological development, the mankind also grow with each passing day to the dependence of electronic installation.Electronic installation on the market at present, many is to utilize Touch Screen (touch panel) or Trackpad (touch pad) to operate.And touch control screen uses because current operating system also can be arranged in pairs or groups, make touch control screen to become one of trend of future development.
Because current touch control screen is on the market increasing, the software that simultaneously meets touch control operation interface also increases rapidly, from the control signal that touch control screen transmitted out, for operating system, all thinks the signal of mouse.This is because touch control screen can, in the time receiving touch-control, change touching signals into corresponding mouse signal.
But in this process, the mouse signal that the continuity of the mouse signal being produced by touching signals can produce than real mouse comes poorly.Also therefore using when touch control screen, the smooth degree of control interface just can be affected.
Summary of the invention
The invention provides a kind of compensation method of touching signals, improve and utilize touching signals to control the smooth degree of vernier.
The present invention proposes a kind of compensation method of touching signals.In the time receiving touching signals, detect the coordinate position of touching signals corresponding to display unit every one period of set time.Judge current coordinate position and last time whether coordinate position was identical.At this, coordinate position is current detected coordinate position at present, and last time coordinate position was front once detected coordinate position.If coordinate position was with last time coordinate position was identical at present, executive signal compensating movement.Signal compensation action comprises offset value calculation, and compensates current coordinate position with offset.
In one embodiment of this invention, above-mentioned judging that current coordinate position is with after step that last time whether coordinate position was identical, if coordinate position was with last time coordinate position was not identical at present, calculate current coordinate position and the displacement between coordinate position last time.And, record this displacement.In addition, last time coordinate position was updated to current coordinate position, with through after the set time, re-executed and detected the step of touching signals corresponding to the coordinate position of display unit.
In one embodiment of this invention, in the step of above-mentioned offset value calculation, can carry out offset value calculation according to above-mentioned displacement.
In one embodiment of this invention, above-mentioned after compensating the step of current coordinate position with offset, a compensation number of times also can add up.And, if coordinate position was with last time coordinate position was identical at present, before the step of executive signal compensating movement, can first detects compensation number of times and whether be greater than a count value.If compensation number of times is not greater than this count value, square executive signal compensating movement; On the other hand, if compensation number of times is greater than this count value, stop executive signal compensating movement.
Based on above-mentioned, can there is executive signal compensating movement when discontinuous at touching signals in the present invention, make the manipulation of touching signals closer to mouse signal, will be more smooth and easy in the use.
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing to be described in detail below.

Embodiment
Generally speaking, when touching signals occurs when discontinuous, may cause the coordinate position of vernier can rest on same point always.But in fact user's finger is to be likely under mobile state always.In order to allow the operation fluency of touching signals can more approach mouse signal, the present invention proposes a kind of compensation method of touching signals, and with in the time that touching signals is discontinuous, executive signal compensating movement, uses the operation fluency that promotes touching signals.
Generally speaking, for example, in the time that touch control unit (Trackpad or Touch Screen) receives touching signals, namely user is by depressing touch control unit, and touching signals will be converted into corresponding coordinate position.In the time that system receives touching signals, when namely user's touch-control is to touch control unit, system just can be sent mouse and press (Mouse down) signal.Afterwards, system starts touching signals to compensate, until user stops pressing touch control unit.In the time that user stops pressing touch control unit, system can be sent mouse and discharge the signal of (Mouse up), touching signals is compensated stopping.
Fig. 1 is the process flow diagram of the compensation method of the touching signals that illustrates according to one embodiment of the invention.Please refer to Fig. 1, in step S105, in the time receiving touching signals, detect the coordinate position of touching signals corresponding to display unit every one period of set time.In the present embodiment, can utilize a timer (timer) during through one period of set time, to obtain the coordinate position that touching signals is corresponding every.
Then,, in step S110, judge current coordinate position and last time whether coordinate position was identical.At this, coordinate position is current detected coordinate position at present, and last time coordinate position was front once detected coordinate position.
If coordinate position was with last time coordinate position was identical at present, expression touching signals may be lost and cause touching signals discontinuous.Now, as shown in step S115, executive signal compensating movement.Signal compensation action comprises offset value calculation, and compensates current coordinate position with offset.And if at present coordinate position was when last time coordinate position was not identical, expression touching signals is not lost, therefore without executive signal compensating movement.
Below illustrate for another embodiment again.Fig. 2 is the process flow diagram of the compensation method of the touching signals that illustrates according to another embodiment of the present invention.In step S205, detect the coordinate position of touching signals corresponding to display unit.Then,, in step S210, judge whether current coordinate position equals last time coordinate position.
If coordinate position is not equal to last time coordinate position at present, expression touching signals is not lost.Now, as shown in step S215, calculate current coordinate position and the displacement between coordinate position (offset) last time.For example, deduct last time coordinate position with current coordinate position.And, in step S220, record displacement.In addition, in step S225, last time coordinate position was updated to current coordinate position.Meanwhile, compensation number of times is made zero.Afterwards, through after the set time, re-execute step S205.
On the other hand, if coordinate position equals last time coordinate position at present, as shown in step S230, detect compensation number of times and whether be greater than count value.If compensation number of times is greater than count value, that is to say that coordinate position continues to exceed the regular hour at same point, now can judge that coordinate position no longer continues mobile, and then no longer carry out signal compensation action.
And if compensation number of times is while being not yet greater than count value, executive signal compensating movement, as shown in step S235, offset value calculation.Afterwards, in step S240, compensate current coordinate position with offset.For example, can carry out offset value calculation (with reference to step S220) according to recorded displacement.General in the situation that, because the translational speed of finger does not have very violent difference, and the discontinuous time of touching signals can't be oversize, under such environment, can, in the time that generation touching signals is discontinuous, utilize previous displacement to compensate.In addition, also can set a susceptibility, and carry out offset value calculation according to susceptibility.Or, can design an algorithm and carry out offset value calculation.
For instance, suppose that the coordinate position A detecting is for the first time (Xa, Ya), the coordinate position B detecting is for the second time (Xb, Yb), and the coordinate position c detecting is for the third time (Xc, Yc).And false coordinate position A is not equal to coordinate position B, and coordinate position B equals coordinate position C.In the time coordinate position B being detected, because coordinate position A is not equal to coordinate position B, therefore just can record the displacement of coordinate position A and coordinate position B, for example (Xb-Xa, Yb-Ya).And in the time coordinate position C being detected, because coordinate position C equals coordinate position B, represent now to produce touching signals discontinuous, therefore just coordinate position C is added to displacement compensates.For example, Xc=Xc+ (Xb-Xa), Yc=Yc+ (Yb-Ya).
Above-mentioned after compensating current coordinate position with offset, as shown in step S245, will compensate number of times cumulative.This is in order to judge whether coordinate position continues to exceed the regular hour at same point, to use and judge whether user stops pressing touch control unit.In addition, in the time that user again touch-control produces touching signals to touch control unit, related data (for example displacement, compensation number of times and offset) can be made zero, use and recalculate offset.
In sum, the present invention judged with last time whether coordinate position is identical whether touching signals is lost by more current coordinate position.If judge touching signals loss, executive signal compensating movement.And, judge by the number of compensation number of times whether user stops the mobile touch control unit that continues to press really.Accordingly, can improve the smooth degree that utilizes touching signals to control vernier.
Although the present invention with embodiment openly as above; so it is not in order to limit the present invention, those skilled in the art, without departing from the spirit and scope of the present invention; when doing a little change and retouching, therefore protection scope of the present invention is when being as the criterion depending on the appended claims person of defining.
