User is divided into two intervals, district at the touch area of touch screen by the touch area-limit that this is preset
Between one: touch area more than zero and less than or equal to preset touch area-limit；Interval two: touch area
More than the touch area-limit preset.
S13, this touch area more than preset touch area-limit time, locking touch screen on this touch sit
Mark corresponding data and wipe the data of locking.
In this step, i.e. when user's touch area on the touchscreen is interval two, touch screen is locked
Go up data corresponding to this touch coordinate and wipe the data of locking.
S14, this touch area less than or equal to preset touch area-limit time, according to user at touch screen
On touch track corresponding to touch coordinate carry out data input.
In this step, i.e. when user's touch area on the touchscreen in interval for the moment, will be according to user
The touch track that current touch coordinate on the touchscreen is corresponding carries out data input.Such as, user is touching
Touching the touch track on screen can be word, numeral, symbol, figure etc..Such as, user is at touch screen
When upper touch track is thicker, then the track inputted is thicker；User's touch track on the touchscreen compares
Time thin, then the track inputted is thinner.As, the word write out with thick finger is the biggest, thin finger because of
The thinnest for the little word write out of area.
Further, in step s 11, this touch area is user initial touch position on the touchscreen
Touch area.
When user performs touch action on the touchscreen, as user by finger pressing touch screen time, from
It is a complete touch operation that family finger starts touch touch screen to leave touch screen to finger.It is common,
User touch operation that the touch operation of touch screen is all a coherent movement (as write on the touchscreen,

Data input is carried out or in same complete touch operation according to user's touch track on the touchscreen
Perform data that on corresponding locking touch screen, this touch coordinate is corresponding and wipe the data of locking.Such as,
If the touch area of the initial touch position that the user obtained in step s 11 is on the touchscreen is less than or equal to
The touch area-limit preset, then carry out data input (example according to user's touch track on the touchscreen
As, write operation), no matter user's touch area in this coherent touch is the most always less than or equal to pre-
If touch area-limit, be all identified as user's touch operation on the touchscreen touching according to user
Touch track on screen carries out data input；Such as the user that obtains in step s 11 on the touchscreen initial
The area that touches of touch location is more than the touch area-limit preset, then this touch coordinate on locking touch screen
Corresponding data also wipe the data of locking, no matter user this coherent touch in touch area whether
Always more than the touch area-limit preset, all user's touch operation on the touchscreen is identified as locking
Data that on touch screen, this touch coordinate is corresponding also wipe the data (such as: erasing operation) of locking.Use
Said method, can avoid in the once complete coherent touch operation of user, repeatedly at erasing and book
Switch between writing, carry out wiping this touch operation particularly with palm, because the feature of palm erasing,
User is to be difficult to keep whole palm to keep contact in whole erase process, i.e. can not ensure hands always
The palm touches area always more than the touch area-limit preset with touch screen；Use said method, so that it may
With the touch area of the initial touch position obtained at the beginning (as palm put do not move on the touchscreen time
The touch area obtained) more than the touch area-limit preset time, user's operation on the touchscreen is known
