In conjunction with shown in Fig. 1 and Fig. 2, described handheld terminal prevents the method for maloperation from including:
S11: the pre-recorded handheld terminal the first gravity sensing data when the first mode of operation, the second gravity sensing data when the second mode of operation;
The handheld terminal 20 of the embodiment of the present invention includes but not limited to that smart mobile phone, portable communication appts, PDA (PersonalDigitalAssistant, personal digital assistant or panel computer), wearable device etc. have touch-control and show the electronic equipment with call function.
The present embodiment can obtain the second gravity sensing data when the first gravity sensing data during the first mode of operation and the second mode of operation by the built-in gravity sensor 22 of handheld terminal 20 or accelerometer. Wherein, the first gravity sensing data and the second gravity sensing data are respectively included in the handheld terminal 20 acceleration of gravity direction on X-axis, Y-axis and Z axis and handheld terminal 20 weight component on three axles in space three-dimensional rectangular coordinate system when the first mode of operation and the second mode of operation. In order to be different from prior art, the embodiment of the present invention for the first mode of operation be talking state, the second mode of operation is described for pull-down state columns state.
In practical application scene, when handheld terminal 20 is in talking state and pull-down state columns state, the heeling condition of handheld terminal 20 and incline direction and be different from the angle of horizontal direction, therefore under two states, the gravity sensing data of handheld terminal 20 are different.
S12: the current gravity sensing data of the gravity sensor record handheld terminal of unlatching;
In the use procedure of handheld terminal 20, gravity sensor 22 detection of unlatching obtains the current gravity sensing data of handheld terminal 20 under current operation status. In like manner, current gravity sensing data include the handheld terminal 20 acceleration of gravity direction on X-axis, Y-axis and Z axis and weight component on three axles in space three-dimensional rectangular coordinate system under current operation status.
S13: by current gravity sensing data compared with the first gravity sensing data and the second gravity sensing data, to judge the current operation status of handheld terminal;
S14: current operation status is the first mode of operation if judging, then the induction channels activation threshold value of handheld terminal is set to first threshold;

For practical application scene of more fitting, the present embodiment judges that current operation status is the process of the first mode of operation or the second mode of operation and is: if the difference of current gravity sensing data and the first gravity sensing data is less than or equal to the first preset variable thresholding, then judge that current operation status is as the first mode of operation; If the difference of current gravity sensing data and the second gravity sensing data is less than or equal to the second preset variable thresholding, then judge that current operation status is as the second mode of operation.
The component value (such as the value of acceleration of gravity direction and weight component) on X-axis, Y-axis and Z axis is included in view of gravity sensing data, therefore the first preset variable thresholding and the second preset variable thresholding also should include the component value on X-axis, Y-axis and Z axis, above-mentioned judge process particularly as follows:

When user needs pull-down state hurdle to call address list in communication process, user face or ear and touch screen 21 disengage, and now touch screen 21 becomes bright screen.
Judging that handheld terminal 20 is in the second mode of operation, such as, when handheld terminal 20 is switched to pull-down state columns state by talking state, owing to finger slides on touch screen 21, touch screen 21 is bigger with the real contact area of finger, induction channels activation threshold value when therefore the induction channels activation threshold value of touch screen 21 is set more than talking state, namely Second Threshold is more than first threshold, the now trigger sensitivity step-down of touch screen 21, user finger contacts bigger area without making touch screen 21 blank screen with touch screen 21.In actual scene, handheld terminal 20 horizontally or diagonally can be 45 ° and still ensures that to contact with finger and reach Second Threshold by β.
It is compared to prior art, the present embodiment judges the current operation status of handheld terminal 20 according to the current gravity sensing data that gravity sensor 22 obtains, and the induction channels activation threshold value of touch screen 21 is set accordingly, namely the gravity sensor 22 by carrying realizes the function of P-sensor, the touch-control sensitivity of touch screen 21 can be adjusted flexibly, show it is thus possible to carry out screen according to service condition accurately, it is not necessary to set up extra induction installation, reduce product cost.
