Description
Technical field
The present invention relates to the bearing calibration of a kind of screen touch electronic device and touch trajectory, particularly a kind ofly calculate the screen touch electronic device of check point position and the bearing calibration of touch trajectory.
Background technology
The main flow of current electronic apparatus, such as smart mobile phone or flat computer etc., all give up traditional keyboard mouse device and change the interface of the input and output using contact panel as standard, with the microminiaturization trend in response to electronic installation.By contact panel, electronic apparatus provides user by the touching of finger on contact panel or slides and perform 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, and the resolution requirement therefore for touch trajectory is also more and more high, otherwise erroneous judgement or the touch trajectory depicted just easily occur not as expected.
Due to common people manipulate on contact panel perform time, often because of centre-of gravity shift or contact area variation, cause touch points position to make a variation and make execution track present non-level and smooth situation, therefore the general equal touch points position that can not directly use detected by contact panel, but linearization process can be carried out to touch points position further.The track that current touch-control tradesman utilizes interpolation method to carry out smoothing user to draw on contact panel for the correction of touch trajectory more.
Please refer to Fig. 1 and Fig. 2, be respectively prior art schematic diagram (), (two).When finger slides on the contact panel 101 of screen touch electronic device 10, contact panel 101 can detect that touch points position 250(comprises A1 ~ A12), now, the processor of screen touch electronic device 10 can carry out linearization process to touch points position 250 and obtain simulation points position 260(A1 ' ~ A12 ').Wherein, A1 ' is A1; A2 ' is calculated with A2 interpolation by A1 ' and obtains; A3 ' is calculated with A3 interpolation by A2 ' and obtains; A4 ' is calculated with A4 interpolation by A3 ' and obtains; The rest may be inferred.
But linearization process causes the problem of time lag also, also namely point complete operation and the touch points position A12 that leaves contact panel 101 place instantly can produce drop with last the calculated simulation points position of linearization process.A kind of mode of existing calculating simulation point position 260, when touching thing stops calculating once leaving contact panel immediately, now, simulation points position may only be calculated to A4 ' just loud, high-pitched sound so stop, the track causing simulation points position 260 to form with touch really track do not meet or difference excessive.Especially, when pointing translational speed and being faster, difference will be more obvious.The touch trajectory that this species diversity causes the erroneous judgement of touch control operation or order to depict most probably is not as expected.
The another kind of practice of prior art is for first to deposit in buffer by touch points position 250, processor obtains touch points position 250 again and processes from buffer, although can calculate all touch points positions 250 and obtain simulation points position 250 thus, the reaction time of touch control operation can be caused elongated and 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 calculating simulation point position, touch points position detected.When processor detects that touch points leaves contact panel, the coordinate (X of touch points position when correction module leaves contact panel according to the touch points that contact panel detects
