Initial value is that the touch pressure of a certain location point input in 0.4N corresponding regions is that (0.5N is detected 0.5N for pressure sensor
The value arrived), then can by 0.5N difference (- 0.2) Ns corresponding with the initial pressure value 0.4 (i.e. pressure calibration value 0.2N with it is initial
Pressure value 0.4N difference) difference be output valves of the 0.7N as the pressure sensor.So as to realize to the pressure sensor
Calibration, by the way that more than 0.2N initial pressure value is pulled down into pressure calibration value 0.2, and for pressure calibration value below 0.2
Without processing, this allows for mobile phone pressure consistency and is protected pressure value.

Determining unit 123 filters out initial pressure value of the pressure value higher than pressure calibration value 0.2N as target pressure value, i.e. 0.4N,
0.3N, and record by pressure calibration unit 124 the pressure calibration value 0.2N and the target pressure value difference, that is, be followed successively by-
0.2N, -0.1N so that packing pressure sensor can be calibrated according to the touch pressure that the difference inputs to user, not high
In pressure calibration value 0.2N initial pressure value 0.1N, 0.2N then without processing.For example, if user is in the initial value
The touch pressure of a certain location point input in 0.4N corresponding regions is 0.5N (0.5N is the value that pressure sensor detects),
Then can be by the 0.5N corresponding with the initial pressure value 0.4 difference (- 0.2) N (i.e. pressure calibration value 0.2N and initial pressure value
0.4N difference) difference be output valves of the 0.7N as the pressure sensor.So as to realize the calibration to the pressure sensor, lead to
Cross and more than 0.2N initial pressure value is pulled down to pressure calibration value 0.2, and for pressure value of the pressure calibration value below 0.2 not
Handled, this allows for mobile phone pressure consistency and is protected.
In embodiments of the present invention, touching for the terminal device can be obtained by being arranged at the pressure sensor of terminal device
Touch the initial pressure value of multiple location points on screen, and according to default pressure calibration value acquire the pressure calibration value with it is each
Initial pressure value in initial pressure value higher than the pressure calibration value is the difference of target pressure value, so as to according to the difference
The touch pressure inputted to the user of subsequent detection is calibrated, it is achieved thereby that the calibration to pressure sensor so that calibration
Pressure sensor afterwards can accurate measurement obtain the touch pressure that user's touch operation actually enters, improve pressure measxurement
Accuracy, and enhance Consumer's Experience.
