Abstract

The information processing apparatus identifies whether a state of a pointer which is close to the display screen is in a hover state or in a touch state. According to the duration pointed by the pointer which is in the hover state, the information processing apparatus sets the priority to each item. When the state of the pointer changes from the hover state to the touch state, the information processing apparatus specifies the item touched by the pointer from the plurality of items according to the touch position and the priority.

Claims

1. An information processing apparatus, comprising:

a display control unit configured to display a plurality of items on a display screen;

an identifying unit configured to identify a state of a pointer which is close to the display screen, whether the pointer is in a hover state or in a touch state;

a determining unit configured to determine priority of each of the plurality of items displayed on the display screen according to a duration pointed by the pointer which is in the hover state to the display screen; and

a specifying unit configured to specify the item touched by the pointer from the plurality of items displayed on the display screen using the priority determined by the determining unit in a case where the state of the pointer identified by the identifying unit is changed from the hover state to the touch state.

2. The information processing apparatus according to claim 1, wherein each of the plurality of items corresponds to processing which is executable in the information processing apparatus, further comprising:

an execution unit configured to execute processing which corresponds to the item specified by the specifying unit.

3. The information processing apparatus according to claim 1, further comprising:

a position detection unit configured to detect, in a case where the pointer is close to the display screen on which the plurality of items are displayed, a position pointed by the pointer; and

wherein the determining unit is further configured to set the priority to the item displayed at the position detected by the position detection unit or the item displayed at a position at which correction value is added to the position detected by the position detection unit.

4. The information processing apparatus according to claim 1, wherein:

the determining unit is further configured to set higher priority to each of the plurality of items having a longer duration pointed by the pointer which is in the hover state; and

the specifying unit is further configured to specify the item selected from the plurality of items according to a position at which the pointer touched the display screen and the priority.

5. The information processing apparatus according to claim 1,

wherein the determining unit is further configured to set the priority to an object according to the duration pointed by the pointer and a history of the object selected in past.

6. The information processing apparatus according to claim 1,

further comprising a display control unit configured such that a display mode of the item having the priority set by the determination unit differs from the display mode of the item prior to setting the priority.

7. The information processing apparatus according to claim 1,

wherein the determination unit is configured to clear the priority after a lapse of a predetermined time after setting the priority.

8. The information processing apparatus according to claim 1,

wherein the determination unit is further configured to clear the priority if the position pointed by the pointer moves more than a predetermined distance from a display position of the item having the priority initially set.

9. The information processing apparatus according to claim 1, further comprising a touch area detection unit configured to detect a touch area at which the pointer touched the display screen,

wherein the specifying unit is further configured to specify the item according to a size of the display area of the item included in the touch area detected by the touch area detection unit and the priority.

10. The information processing apparatus according to claim 9,

wherein the specifying unit is further configured to select, in a case where the display area of the item having the priority set is not included in the touch area, if one or more display areas of the item to which no priority is set are included in the touch area, the object according to the size of the display area of the item to which no priority is set included in the touch area.

11. The information processing apparatus according to claim 10,

wherein the specifying unit is further configured to select the item according to the priority in a case where the display area of the item is not included in the touch area.

12. The information processing apparatus according to claim 1,

wherein the hover state is a state in which the pointer is within a predetermined distance from the display screen and the pointer does not touch the display screen.

13. An input method executed by an information processing apparatus having a display screen on which a plurality of items are displayed, comprising:

identifying a state of a pointer which is close to the display screen, whether it is in a hover state or in a touch state;

determining priority of each of the plurality of items displayed on the display screen according to duration pointed by the pointer which is in the hover state to the display screen;

specifying the item touched by the pointer from the plurality of items displayed on the display screen based on the priority in a case where the state of the pointer is changed from the hover state to the touch state.

14. A computer readable recording medium containing computer program for causing a computer comprising a display screen on which a plurality of items are displayed to function as:

an identifying unit configured to identify a state of a pointer which is close to the display screen, whether it is in a hover state or in a touch state;

a determining unit configured to determine priority of each of the plurality of items displayed on the display screen according to duration pointed by the pointer which is in the hover state to the display screen; and

a specifying unit configured to specify the item touched by the pointer from the plurality of items displayed on the display screen based on the priority determined by the determining unit in a case where the state of the pointer identified by the identifying unit is changed from the hover state to the touch state.
