Abstract

When a touch panel is operated and erroneous processing has been performed, the probability of the same operation error next time is reduced. For this purpose, when a touch to the touch panel is detected, one of respective items in a menu, which the touch position belongs to is determined. Then processing regarding the determined item is performed. At this time, when a designation input indicating that the selection of the item corresponding to the executed processing was not intended by the operator has been made, to narrow a decision area to decide selection of the item, information indicating the decision area is updated.

Claims

1. An electronic device having a display device, and a touch panel, provided in front of a display screen of the display device, to detect an operator'"'"'s touch position, comprising:

a storage unit to hold decision area information indicating a decision area to decide selection of an item as a selection subject to be displayed on said display screen;

a display control unit to control said display device to display respective items;

a control unit to, when a touch to said touch panel is detected, determine a selected item by referring to said storage unit and determining a decision area which the touch position belongs to, and perform processing corresponding to the determined selected item,

wherein said control unit has;

a determination unit to, when the processing corresponding to said selected item is started, determine whether or not a designation input indicating that selection of the processing-started item was not intended by the operator has been made; and

an update unit to, when said determination unit determines that said designation input has been made, update corresponding decision area information in said storage unit so as to narrow said decision area of an item corresponding to the started processing.

2. The electronic device according to claim 1, wherein said update unit updates said decision area information corresponding to said decision area such that said touch position is outside a border of the decision area of said processing-started item.

3. The electronic device according to claim 2, wherein said update unit updates the decision area information of the respective decision areas such that said touch position is positioned in the border between the decision area of said processing-started item and the decision area of an item adjacent to said selected item.

4. The electronic device according to claim 1, wherein when said determination unit determines that said designation input has been made, said started processing is aborted.

5. The electronic device according to claim 1, wherein said determination unit displays a key to designate processing of an item not intended by the operator on a screen showing progress of the started processing, and determines whether or not the key has been touched.

6. The electronic device according to claim 1, wherein said determination unit determines whether or not a hardware key designating processing of an item not intended by the operator has been operated.

7. The electronic device according to claim 1, wherein said determination unit displays a key to abort processing on a screen indicating the progress of the started processing, and determines whether or not touch operation with respect to said key has been detected a predetermined number of times.

8. A control method for an electronic device having a display device, and a touch panel, provided in front of a display screen of the display device, to detect an operator'"'"'s touch position, and a storage unit to hold decision area information indicating a decision area to decide selection of an item as a selection subject to be displayed on said display screen, comprising:

a display control step of controlling said display device to display respective items; and

a control step of, when a touch to said touch panel is detected, determining a selected item by referring to said storage unit and determining a decision area which the touch position belongs to, and performing processing corresponding to the determined selected item,

wherein said control step has;

a determination step of, when the processing corresponding to said selected item is started, determining whether or not a designation input indicating that selection of the processing-started item was not intended by the operator has been made; and

an updating step of, when it is determined at said determination step that said designation input has been made, updating corresponding decision area information in said storage unit so as to narrow said decision area of an item corresponding to the started processing.

9. A non-transitory computer-readable storage medium holding a program to be read and executed by a computer, and to cause said computer to execute the respective steps of the method in claim 8.

10. An information processing apparatus having a touch panel comprising:

a specifying unit to specify a selected item by recognizing touch operation by a user;

a first determination unit to determine whether or not the user has made cancel operation after said touch operation;

a second determination unit to, when said first determination unit determines that said cancel operation has been made, determine that said touch operation was an erroneous operation;

an update unit to, when said second determination unit determines that said touch operation was an erroneous operation, update a touch decision area corresponding to said selected item.

11. The information processing apparatus according to claim 10, wherein said second determination unit makes determination based on a period between time related to said touch operation and time related to said cancel operation.

12. The information processing apparatus according to claim 10, wherein said second determination unit makes a determination based on a display size of said selected item.

13. The information processing apparatus according to claim 10, wherein said second determination unit makes a determination based on a period between time related to said touch operation and time related to said cancel operation, and a display size of said selected item.

14. The information processing apparatus according to claim 10, wherein said update unit updates said touch decision area so as to narrow the touch decision area corresponding to said selected item.

15. The information processing apparatus according to claim 10, wherein said update unit updates said touch decision area not to include the touch position of said touch operation.

16. The information processing apparatus according to claim 10, wherein said second determination unit obtains a probability that said touch operation was an erroneous operation,

and wherein said update unit updates said touch decision area based on the probability of erroneous operation.

17. The information processing apparatus according to claim 16, wherein said update unit updates said touch decision area so as to reduce the touch decision area when said probability of erroneous operation is high to be narrower than the touch decision area when said probability of erroneous operation is low.

18. A control method for an information processing apparatus having a touch panel, comprising:

a specifying step of specifying a selected item by recognizing touch operation by a user;

a first determination step of determining whether or not the user has made cancel operation after said touch operation;

a second determination step of, when it is determined in said first determination step that said cancel operation has been made, determining that said touch operation was an erroneous operation; and

an update step of, when it is determined that said touch operation was an erroneous operation, updating a touch decision area corresponding to said selected item.

19. A non-transitory computer-readable storage medium holding a program to be read and executed by a computer, and to cause said computer to execute the respective steps of the method in claim 18.
