Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's acquired every other implementation without creative efforts
Example, shall fall within the protection scope of the present invention.
First embodiment
It is the flow chart provided in an embodiment of the present invention for touching initial position recognition methods referring to Fig. 1, Fig. 1, such as Fig. 1 institute
Show, method includes the following steps:
Step 101, when detecting user when touch screen be in the first scan frequency input touch slide, described in switching
First scan frequency of touch screen is to the second scan frequency, wherein first scan frequency is less than the second scan frequency.
When carrying out touch slide on the touch screen of mobile terminal, the touch control component of mobile terminal can detecte user
Finger signal, and obtain after finger touches corresponding each touch point and report corresponding report point.However, based on examining for power consumption is reduced
Consider, after in user, operation touch-screen does not reach threshold time, such as 1 second, touch control component can enter low-power consumption mode.Into low function
After consumption mode, scan frequency can be reduced, i.e., is scanned according to the first scan frequency of lower frequency to obtain touch point.It is touching
When touching screen in the first scan frequency, when detecting that user, can be by touch screen when touch screen inputs and touches slide
First scan frequency switches to the second scan frequency, wherein the first scan frequency is less than the second scan frequency.
In the step, the touch slide that above-mentioned user inputs in touch screen can be mobile terminal in bright screen state
When, touch slide that user inputs on the touchscreen；It is also possible to have the mobile terminal of gesture function to shield standby shape in breath
When state, touch slide that user inputs on the touchscreen.
Step 102 detects first report point coordinate value for touching slide and the with second scan frequency
Two report point coordinate values.
Since mobile terminal is when receiving the touch of user on the touchscreen, touch control component needs never to receive touch
Low-power consumption mode switch to operating mode, i.e., touch control component needs to switch to the second scan frequency from the first scan frequency, after
And report report point data.Although the process of above-mentioned switching is very fast, always need to expend some times, for the touch of user's input
For slide, it is easy to which the actual initial touch coordinate of finger can be lagged behind by causing the coordinate of first report point.And with
The sliding speed of user on the touchscreen is faster, and the distance that first report point coordinate lags behind the practical initial touch coordinate of finger is got over
Greatly.It is to be understood that user is inputted on the touchscreen when touching slide, mobile terminal can not often identify that finger touches
Beginning position.
As Figure 1-1, point S1, S2 are the actual sliding trace of finger, and wherein S1 is that finger touches starting point；Point S1',
S2' is the track that mobile terminal is shown, wherein S1' is first report point, and S2' is second report point.Finger touches starting point S1
There are relatively large deviation between first report point S1', this deviation is exactly by low-power consumption mode by touch control component to reporting report to count
Caused by the time expended during.And finger sliding speed is bigger, deviation is bigger, and point S1' range points S1 is remoter.
In the step, after mobile terminal switches the scan frequency to the second scan frequency of touch screen, it can be swept with second
Frequency is retouched to detect the first report point coordinate value and second report point coordinate value that touch slide, with first report point coordinate
For value, first report, which puts coordinate value, can be the coordinate value that first report puts present position on the touchscreen, it can be understood as,
First report point coordinate value may include x-axis coordinate value and y-axis coordinate value.As shown in Figs. 1-2, first report point coordinate value can be with
For S1'(x1, y1), second report point coordinate value can be S2'(x2, y2)。
Step 103, according to first report point coordinate value, second report point coordinate value and preset calibration be
Number calculates the corresponding starting report point coordinate value of the initial touch coordinate for touching slide.
In the step, mobile terminal can be according to the first report point coordinate value S1'(x detected in step 1021, y1),
Two report point coordinate value S2'(x2, y2) and pre-set calibration factor a, calculate received touch sliding behaviour in step 101
The corresponding starting report point coordinate value S0 (x of the initial touch coordinate of work0, y0)。
In the embodiment of the present invention, above-mentioned mobile terminal can be any equipment with touch screen, such as: mobile phone, plate
Computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant
(personal digital assistant, abbreviation PDA), mobile Internet access electronic equipment (Mobile Internet Device,
