Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Embodiment 1
Seeing also Fig. 1, is the first embodiment of the invention touch screen unlocking method, comprising:
S101, when touch screen lock regularly, if detect the user in the clicking operation of touch-screen, then according to the current contact position of clicking touch screen unlocking is set and pulls the district.
Particularly, when the touch screen lock timing, terminal detects the user when the click event of touch-screen, determines the corresponding current contact of this click event position, being the center of circle with the current contact position, is that border circular areas that radius forms is set to release and pulls the district with the predeterminable range.When touch-screen slip release, the position that the user points initial touching touch-screen can be set to the current contact position.
Predeterminable range can also can should be appreciated that the terminal of the embodiment of the invention comprises: mobile phone, panel computer etc. by the manufacturer terminal setting by the user according to self use habit setting.
S102, according to the current contact position of clicking the touch screen unlocking target area is set;
Particularly, according to the current contact position that the user clicks screen is carried out subregion, form at least two described release target areas, the function that terminal is built-in is associated with described two described release target areas respectively at least, so that open corresponding function during the release touch-screen.
The built-in function of the terminal that is associated with the release target area can be by the user according to the use habit setting, and the function that frequency of utilization is high is associated with the release target area, avoids elder generation to touch screen unlocking, enters the built-in function of terminal by clicking repeatedly again.
Seeing also Fig. 5, is embodiment of the invention touch-screen subregion synoptic diagram, can touch-screen be divided into 9 zones according to nine palace lattice principles, is respectively nine districts, first district to the, and AE and CG are the diagonal line of touch-screen, and BF and HD are respectively two center lines of touch-screen.
If the current contact position of clicking is positioned at first district or the 3rd district or SECTOR-SEVEN or the 9th district, with any one among two diagonal line AE passing touch-screen and the CG be the separatrix, touch-screen is divided into release pulls and distinguish and the release target area.
If the current contact position of clicking is positioned at second district or the 5th district or Section Eight, is the separatrix with center line BF and the HD that passes second district, the 5th district, Section Eight, touch-screen is divided into release pulls district and release target area.
If the current contact position of clicking is positioned at the 4th district or the 6th district, is the separatrix with center line BF and the HD that passes the 4th district, the 5th district, Section Eight, touch-screen is divided into release pulls district and release target area.
If the current contact position of clicking is positioned at the point of crossing in the point of crossing of the point of crossing in first district, second district, the 4th district, the 5th district or point of crossing that the current contact position is positioned at second district, the 3rd district, the 5th district, the 6th district or the 4th district, the 5th district, SECTOR-SEVEN, Section Eight or the 5th district, the 6th district, Section Eight, the 9th district, with any one among two diagonal line AE passing touch-screen and the CG be the separatrix, touch-screen is divided into release pulls district and release target area.
Certainly, touch-screen is divided into release pulls the district and the partitioned mode of release target area is not limited to upper type, manufacturer terminal or user can reach use habit according to actual needs, with the touch-screen subregion.
S103, when detect with described pull the district move to described release target area, the release touch-screen is to open the corresponding function in described release target area.
Particularly, with the touch screen zone at final contact position place, as selected release target area, when detecting the described district that pulls is moved to described selected release target area, the release touch-screen is to open the described selected corresponding function in release target area.
When touch-screen slip release, the position that the user points final stop can be set to final contact position, with the touch screen zone at final contact position place, as selected release target area.
For example, if final contact position is in the zone, lower left of diagonal line AE, then should the zone as selected release target area, accordingly, the zone, upper right side of diagonal line AE pulls the district as selected release, when terminal detect with release pull the district move to selected release target area, the release touch-screen is finished the release of touch-screen to open the selected corresponding function in release target area.
Perhaps, to slide into the touch screen zone at the place, path of final contact position from the current contact position, as selected release target area, move to selected release target area when detecting with pulling the district, the release touch-screen is to open the selected corresponding function in release target area.
For example, the touch screen zone that the current contact position slides into the place, path of final contact position is the left field of center line BF, then should the zone as selected release target area, release is pulled the district move to selected release target area when terminal detects, the release touch-screen is finished the release of touch-screen to open the selected corresponding function in release target area.
The touch screen unlocking method of the embodiment of the invention and device, can be by the clicking operation at touch-screen, release target area and release are set flexibly pull the district, expanded the usable range that release target area and release pull the district, can effectively reduce the difficulty of touch screen unlocking, be convenient to have the user of vision disorder or point inflexible user's use, promote the user and experience.
