The mobile terminal comprises a terminal with a touch screen, such as a smart phone, a tablet personal computer and the like, when a user touches a key control on the touch screen, the operation corresponding to the key control is not immediately executed, but the touch point of the user after touching the key control is detected, and when the trace formed by the touch point is detected to be a backtracking trace, the operation corresponding to the key control is executed, so that the user can be prevented from mistakenly touching. For example, a sending key of the mail is set as a key control, when the user clicks the sending key, the mail is not sent immediately, and the operation of sending the mail is executed after the backtracking track is detected, so that the loss caused by mistaken touch to the user can be avoided, and the user experience is improved.
Fig. 1 is a flowchart of a preferred embodiment of a method for processing a touch of a control of a mobile terminal according to the present invention, and as shown in fig. 1, the method for processing a touch of a control of a mobile terminal according to the present invention includes the following steps:
step S100, when detecting that a key control preset in the mobile terminal is touched, acquiring a touch point on a touch screen of the mobile terminal and a touch track formed by the touch point.
Specifically, the key control of the mobile terminal can be set by the user, or can be set during production of the mobile terminal, for example, sending keys of APPs such as mails, short messages, QQ, WeChat and the like can be set as the key control, when the sending key is detected to be touched by the user, sending operation is not executed first, after the sending key is touched, a touch point where the user touches the touch screen of the mobile terminal and a track formed by the touch point are detected, when the touch track meets a preset condition, sending operation is executed, otherwise, mistaken touch is judged, and sending operation is not executed.
Step S200, judging whether the distance between all touch points before the touch point separated from the last touch point by the preset point is smaller than the distance threshold value, if so, the current touch track is the backtrack track.
In a further embodiment, the step S200 specifically includes:
setting touch point points on current touch trackIs other than P0P1P2…PN-1PN，PKIs P0And PN-MK and M are natural numbers greater than 1, and N is greater than M, calculating PKAnd PNThe formula of the distance between is:
wherein, XPKIs a touch point PKAbscissa of (a), YPKIs a touch point PKOrdinate of (3), XPNIs a touch point PNAbscissa of (a), YPNIs a touch point PNOn the ordinate of, if PKAnd PNIf the distance between the touch trajectory and the touch trajectory is smaller than the distance threshold, the current touch trajectory is a backtracking trajectory.
In particular, P is to sayN-MAnd the last touch point PNAt a distance of M touch points, at PN-MAmong the previous touch points, i.e. P0And PN-MIn any touch point, only one touch point and PNThe distance between the touch points is smaller than the distance threshold value, and the current touch track can be judged to be a backtracking track. The M value is set to prevent P from being caused by jitter during touchNAnd PN-M、…、PN-1These touch point contacts form a backtracking trajectory trigger touch active, preferably, M is 10.
In a further embodiment, the step S200 may further include:
and after the Mth touch point is detected, judging whether the current touch track forms a backtracking track or not every time one touch point is detected.
Specifically, in order to make the determination process faster, the determination may be performed after the number of touch points reaches M, and after the number of touch points reaches M, it is determined whether a backtracking track is formed in the current touch track once every time one touch point is detected. Why is the touch point not judged within M? Touch point P because the touch points are within MNIs less than M, thenWill not have PN-MThis point cannot be determined.
And step S300, if the current touch track is a backtracking track, executing operation corresponding to the key control.
In a further embodiment, after the step S300, the method further includes:
if the current touch track is the backtracking track, the distance threshold value is modified to be 101% of the current distance threshold value;
if the current touch trajectory is not the backtracking trajectory, the distance threshold is modified to 99% of the current distance threshold.
Specifically, a distance threshold is set as D, whether a backtracking track is formed by each touch operation on the key control is determined, if a backtracking track is formed, the current value of D is modified to D × 99%, that is, the modified distance threshold D 'is D × 99%, for example, if the current value of D is 100, D' is 99 when determining whether a backtracking track is formed next time after modification, that is, when determining that a backtracking track is formed, it is determined that the current value of D is too large, and P is too largeKAnd PNThe distance between the two is easily smaller than D, and then the value of D needs to be reduced; if no backtracking track is formed, the current value D is modified to D101%, that is, the modified distance threshold value D 'is D101%, for example, if the current value D is 100, then D' is 101 when determining whether a backtracking track is formed next time after modification, that is, when determining that a backtracking track is not formed, it means that the current value D is too small, P is too small, and P is not formedKAnd PNThe distance between the two is difficult to be smaller than D, and the value of D is adjusted to be larger.
In a further embodiment, after the step S300, the method further includes:
if the current touch track is a backtracking track, P is calculated respectively0P1P2…PN-MThese points and PNIf the distance threshold is not ranked at the top 10%, the distance threshold is modified to be 101% of the current distance threshold and/or the current value of M is modified to be M + 1.
Specifically, after each judgment, D and M are adjusted according to the judgment condition, so that the difficulty in the next operation can be increased, and the false touch can be better avoided, because the difficulty that the trace formed by the next touch is judged to be the backtracking trace is increased by the method after the current value of D is modified to D × 99% and/or the current value of M is modified to M +1, and if the current trace is judged to be the backtracking trace easily, the current judgment method loses the original purpose of preventing the false touch.
In a further embodiment, the touch point P0And the coordinate point of the key control is taken as the coordinate point of the key control.
Specifically, the touch point P0Is the first point on the touch trajectory, touch point P0Touch point detection is triggered on the key control, i.e., when the key control is pressed.
In a further embodiment, the distance threshold is 50 pixels.
Specifically, the distance threshold D is 50 pixels, and the touch screen coordinates of the mobile terminal can be in one-to-one correspondence with the pixel points, that is, a pixel point coordinate system is adopted, so that P is calculatedKAnd PNIs also the distance between PKAnd PNIf the pixel point with the phase difference is found, P can be obtainedKAnd PNThe pixel points with the difference are compared with a distance threshold value D.
In a further embodiment, a key control needs to be set on the mobile terminal in advance. The key control comprises an APP sending key such as a mail, a short message, a QQ and a WeChat. The specific key control comprises which keys can be set by a user according to needs, and can also be preset by a mobile terminal manufacturer.
