Abstract

A method for unlocking a touch screen is applicable to an electronic device having a touch screen. The method includes displaying a main object on the touch screen upon the touch screen being locked; displaying a plurality of secondary objects in an arrangement on the touch screen upon a physical object touching the main object; highlighting the main object or one of the secondary objects when the touching has lasted for a first period; de-highlighting the highlighted and highlighting the main object or another of the secondary objects on the touch screen, when the touching has lasted for a second period longer than the first period; and upon the physical object leaving the touch screen when the main object or a secondary object is highlighted, unlocking the touch screen. And then a step of activating an application corresponding to the highlighted object may be performed.

Claims

1. A method for unlocking a touch screen, applicable to an electronic device that has a touch screen, the method comprising the steps of:

displaying a main object on the touch screen, upon the touch screen being locked;

displaying a plurality of secondary objects in an arrangement on the touch screen upon a physical object touching a position on the touch screen corresponding to the main object;

highlighting the main object or at least one of the secondary objects on the touch screen when the physical object'"'"'s touch on the position has lasted for a first period;

de-highlighting the main object or said at least one of the secondary objects on the touch screen and highlighting the main object or another of the secondary objects on the touch screen, when the physical object'"'"'s touch on the position has lasted for a second period, wherein the second period is longer than the first period; and

upon the physical object leaving the position on the touch screen when a secondary object of the secondary objects is highlighted, unlocking the touch screen and activating an application corresponding to the secondary object.

2. The unlocking method according to claim 1 further comprising a step of the electronic device performing a configuring program to determine the arrangement of the secondary objects on the touch screen.

3. The unlocking method according to claim 2 further comprising a step of the electronic device performing the configuring program to determine the arrangement of the secondary objects on the touch screen, according to the number of times the application has been activated.

4. The unlocking method according to claim 1 further comprising a step of the electronic device performing a configuring program to determine a sequence in which the secondary objects are highlighted on the touch screen.

5. The unlocking method according to claim 4 further comprising a step of the electronic device performing the configuring program to determine the sequence in which the secondary objects are highlighted on the touch screen, according to the number of times the application has been activated.

6. The unlocking method according to claim 1 further comprising a step of the electronic device performing a calculating program to calculate the number of times the application has been activated.

7. The unlocking method according to claim 1 further comprising a step of the electronic device performing a calculating program to calculate the number of times the application has been activated upon the touch screen being unlocked.

8. The unlocking method according to claim 1 further comprising a step of upon the physical object leaving the position on the touch screen when the main object is highlighted, unlocking the touch screen.

9. The unlocking method according to claim 1 further comprising a step of upon the physical object leaving the position on the touch screen when the main object is highlighted, unlocking the touch screen and displaying a function menu of the electronic device on the touch screen.

10. The unlocking method according to claim 1, wherein in the step of displaying a plurality of secondary objects in an arrangement, the secondary objects move away from the position of the main object in order to form the arrangement on the touch screen.

11. A method for unlocking a touch screen, applicable to an electronic device that has a touch screen, the method comprising the steps of:

displaying a main object on the touch screen, upon the touch screen being locked;

displaying a plurality of secondary objects in an arrangement on the touch screen upon a physical object touching a position on the touch screen corresponding to the main object;

highlighting the main object or at least one of the secondary objects on the touch screen when the physical object'"'"'s touch on the position has lasted for a first period;

de-highlighting the main object or said at least one of the secondary objects on the touch screen and highlighting the main object or another of the secondary objects on the touch screen, when the physical object'"'"'s touch on the position has lasted for a second period, wherein the second period is longer than the first period; and

upon the physical object leaving the position on the touch screen-when the main object or a secondary object of the secondary objects is highlighted, unlocking the touch screen.
