Abstract

A mobile phone apparatus is provided with an accelerometer for detecting an attitude and a display for displaying a moving object. Furthermore, a key locked state is set to the mobile phone apparatus for the purpose of preventing an operating error in the key. When an arbitrary key is operated in the key locked state, the moving object and a pocket object representing a predetermined area, etc. are displayed on the display. Then, when the moving object changes in position in correspondence with the change of the attitude of the mobile phone apparatus and is put into the pocket object, the key locked state is cancelled.

Claims

1. A mobile terminal capable of setting a locked state and having a detector to detect an attitude and a displayer to display a moving object on a screen, the mobile terminal comprising:

a setter which sets a predetermined area on said screen;

a changer which changes an on-screen position of said moving object on the basis of changes of the attitude detected by said detector, wherein the on-screen position of said moving object represents a center of gravity of the moving object;

a determiner which determines whether or not said on-screen position of said moving object and said predetermined area have a predetermined relationship; and

a canceller which cancels the locked state when said determiner determines that said on-screen position of said moving object and said predetermined area have said predetermined relationship.

2. A mobile terminal according to claim 1, wherein said determiner determines that said moving object and said predetermined area have said predetermined relationship when said on-screen position of said moving object enters said predetermined area.

3. A mobile terminal according to claim 2, wherein said setter includes a first setter which sets a first predetermined area and a second setter which sets a second predetermined area, and said determiner determines that said moving object and said predetermined area have said predetermined relationship when said on-screen position of said moving object enters said first predetermined area and said second predetermined area.

4. A mobile terminal according to claim 3, wherein said second setter sets said second predetermined area when said on-screen position of said moving object enters said first predetermined area.

5. A mobile terminal according to claim 1, wherein said determiner determines that said moving object and said predetermined area have said predetermined relationship when said moving object crosses said predetermined area.

6. A mobile terminal according to claim 1, further comprising:

a calculator which calculates a moving velocity of said moving object when said on-screen position of said moving object changes, wherein said determiner determines whether or not said moving object and said predetermined area have a predetermined relationship when the moving velocity calculated by said calculator is equal to or more than a predetermined value.

7. A mobile terminal according to claim 1, further comprising:

a recorder which records a moving path when said on-screen position of said moving object is changed by said changer, wherein said determiner determines that said on-screen position of said moving object and said predetermined area have said predetermined relationship when the moving path recorded by said recorder is included said predetermined area.

8. A locked state cancelling method of a mobile terminal capable of setting a locked state and having a detector to detect an attitude and a displayer to display a moving object on a screen, the method comprising:

setting a predetermined area on said screen;

changing an on-screen position of said moving object on the basis of changes of the attitude detected by said detector, wherein the on-screen position of said moving object represents a center of gravity of the moving object;

determining whether or not said on-screen position of said moving object and said predetermined area have a predetermined relationship; and

cancelling the locked state when said determiner determines that said on-screen position of said moving object and said predetermined area have said predetermined relationship.

9. A method of canceling a locked state of a mobile terminal, the method comprising using at least one hardware processor to:

if the mobile terminal is in a locked state, display a screen with an object and at least one predetermined area;

change an on-screen position of the object based on a change in an attitude of the mobile terminal, wherein the on-screen position of the object represents a center of gravity of the object;

determine whether the on-screen position of the object has a predetermined relationship with the at least one predetermined area; and

,

if the on-screen position of the object has the predetermined relationship with the at least one predetermined area, switch the mobile terminal to an unlocked state.

10. The method of claim 9, wherein the attitude comprises an angle of the mobile terminal.

11. The method of claim 9, further comprising using the at least one hardware processor to:

receive three-axis acceleration data from an accelerometer of the mobile terminal; and

calculate the attitude of the mobile terminal based on the three-axis acceleration data.

12. The method of claim 11, where calculating the attitude of the mobile terminal based on the three-axis acceleration data comprises applying an inverse trigonometric function to the three-axis acceleration data.

13. The method of claim 11, further comprising using the at least one hardware processor to:

upon display of the screen, temporarily store initial three-axis acceleration data from the accelerometer; and

correct the attitude of the mobile terminal based on the initial three-axis acceleration data.

14. The method of claim 13, wherein correcting the attitude comprises subtracting subsequently received three-axis acceleration data from the initial three-axis acceleration data.

15. The method of claim 9, wherein the object comprises a depiction of a ball, and wherein the at least one predetermined area comprises a depiction of a hole.

16. The method of claim 15, wherein the at least one predetermined area comprises a plurality of predetermined areas comprising a plurality of depictions of a hole in different regions of the screen.

17. The method of claim 9, wherein determining whether the on-screen position of the object has a predetermined relationship with the at least one predetermined area comprises determining whether the on-screen position of the object is within the at least one predetermined area.

18. The method of claim 9, wherein the at least one predetermined area comprises a plurality of predetermined areas, and wherein determining whether the on-screen position of the object has a predetermined relationship with the plurality of predetermined areas comprises determining whether the on-screen position of the object has entered one or more of the plurality of predetermined areas in a predetermined order.

19. The method of claim 18, further comprising receiving the predetermined order from a user.

20. The method of claim 9, wherein the predetermined relationship comprises a path, and wherein determining whether the on-screen position of the object has the predetermined relationship with the at least one predetermined area comprises:

storing a plurality of on-screen positions of the object; and

determining whether the plurality of on-screen positions represent the predetermined path.
