Math judgment mode during concrete estimation is: works as f ' (x (1)) * f ' (x (k)) >=0, wherein, f ' representative function is asked
Lead, determine function and be incremented by all the time or decreasing function, then obtain pressing position not estimating in described pressure buttons response region
Meter result；Work as f ' (x (1)) * f ' (x (k)) < 0, determining function is first to be incremented by rear decreasing function, then obtain pressing position in institute
State the estimated result of pressure buttons response region.
Further, in the embodiment of the present invention, if the pressing position estimating, in described pressure buttons response region, is known
Other module 330 determines that this pressing position corresponding pressing threshold value is the standard pressing threshold value setting；If the pressing position estimating
Not in described pressure buttons response region, then identification module 330 determines that this pressing position corresponding pressing threshold value is the setting
One pressing threshold value；Wherein, the first pressing threshold value is more than standard pressing threshold value, more precisely, the first pressing threshold value is far longer than
Standard presses threshold value, thus ensureing can reduce false touch as far as possible while user's pressing response sensitivity.
In summary, the embodiment of the present invention, according to the pressure value distribution situation in pressure buttons response region, can to
The pressing position at family is estimated, and adjusts the pressing response lag of pressure buttons it is ensured that pressing according to different pressing positions
