Abstract
A method for unlocking a touch screen of an electronic device includes the following steps. First, touch signals are generated in response to manual touch operations on the touch screen. Second, a shape is identified according to the touch signals. Third, the touch screen is unlocked if the identified shape is substantially the same as a predefined shape, wherein the predefined shape is a shape of two fingertips simultaneously sliding in a direction from up to down on the touch screen. An electronic device equipped for unlocking a touch screen thereof is also provided.
Claims6
A method for unlocking a touch screen of an electronic device having a storage unit, the storage unit having a predefined shape stored therein, the predefined shape being a shape of two fingertips simultaneously sliding in a direction from up to down on the touch screen, the method comprising:
- generating input signals in response to slide operations applied on the touch screen;
- identifying a shape according to the input signals;
- comparing the identified shape with the predefined shape and determining whether the identified shape is substantially the same as the predefined shape;
- and
- unlocking the touch screen when the identified shape is substantially the same as the predefined shape.
An electronic device, comprising:
- a storage unit having a predefined shape stored therein, the predefined shape being a shape of two fingertips simultaneously sliding in a direction from up to down on the touch screen;
- a touch screen, configured for generating input signals in response to slide operations applied thereon;
- a shape identification module, configured for identifying a shape according to the input signals;
- a comparison module, configured for comparing the identified shape with the predefined shape stored in the storage unit, and for determining whether the identified shape is substantially the same as the predefined shape;
- and
- an unlocking module, configured for unlocking the touch screen when the identified shape is substantially the same as the predefined shape.
