Description
Technical field
The present invention relates to the bearing calibration of a kind of screen touch electronic device and touch trajectory, but the particularly screen touch electronic device of a kind of calculation correction point position and the bearing calibration of touch trajectory.
Background technology
The present main flow of electronic apparatus, such as smart mobile phone or flat computer etc. all given up traditional keyboard mouse device and changed with the interface of contact panel as the input and output of standard, with the microminiaturization trend in response to electronic installation.By contact panel, electronic apparatus provides the user by pointing the touching on contact panel or sliding and carry out touch control operation.
And making rapid progress along with touch-control and hardware technology, touch control operation is more and more hommization also, many touch control operation modes are also more and more fine and smooth, therefore also more and more high for the resolution requirement of touch trajectory, otherwise the touch trajectory that just easily occurs to judge by accident or depict is not as expection.
Control on contact panel due to common people when carrying out, tend to because of centre-of gravity shift or contact area variation, cause touch points position variation to make the execution track present non-level and smooth situation, therefore generally all can directly not use the detected touch points of contact panel position, but can be further to the touch points position carrying out linearization process.The present touch-control tradesman contact panel of track utilize interpolation method to come the smoothing user to draw on to(for) the correction of touch trajectory more.
Please refer to Fig. 1 and Fig. 2, be respectively prior art schematic diagram (), (two).When sliding on the contact panel 101 of finger at screen touch electronic device 10, contact panel 101 can detect touch points position 250(and comprise A1 ~ A12), at this moment, the processor of screen touch electronic device 10 can carry out linearization process and obtain simulation points position 260(A1 ' ~ A12 ' touch points position 250).Wherein, A1 ' is A1; A2 ' is calculated and gets with the A2 interpolation by A1 '; A3 ' is calculated and gets with the A3 interpolation by A2 '; A4 ' is calculated and gets with the A4 interpolation by A3 '; The rest may be inferred.
But linearization process causes the problem of time lag also, also namely point complete operation and leave contact panel 101 instantly the touch points position A12 at place can produce drop with the last simulation points position that calculates of linearization process.The mode of a kind of existing calculating simulation points position 260, when the touching thing stops calculating once leaving contact panel immediately, at this moment, the simulation points position may only be calculated to A4 ' just loud, high-pitched sound so stop, the track that causes simulation points position 260 to consist of do not meet with real touching track or difference excessive.Especially heal when fast when the finger translational speed, difference will heal obviously.This species diversity causes the erroneous judgement of touch control operation or the touch trajectory that order is depicted not as expection most probably.
The another kind of practice of prior art is for first depositing in touch points position 250 in buffer, processor obtains touch points position 250 again and processes from buffer, although can calculate and obtain simulation points position 250 all touch points position 250 thus, the reaction time that can cause touch control operation be elongated and the touch control operation generation time is postponed.
Summary of the invention
In view of this, the invention provides a kind of screen touch electronic device, comprise contact panel, processor and correction module.Wherein, processor detects at least one touch points position every an interval time, and processor is again according to the touching calculation of points simulation points position that detects.When processor detects touch points and leaves contact panel, the coordinate (X of the touch points position the when touch points that correction module detects according to contact panel is left contact panel
1, Y
1) and the coordinate (X of processor calculated at last simulation points position
2, Y
2) calculate a plurality of check points positions, in order to proofread and correct the error between simulation points position and touch points position, screen touch electronic device is by simulation points position and check point position execution touch control operation.
The present invention also provides a kind of bearing calibration of touch trajectory, is applicable to have contact panel, the screen touch electronic device of processor and correction module.The bearing calibration of described touch trajectory comprises: processor detects at least one touch points position every an interval time, and processor is again according to the touching calculation of points simulation points position that detects; When processor detects the touching thing when leaving contact panel, the coordinate (X of the touch points position when correction module touch points detected according to processor left contact panel
