Abstract

There is provided an information processing apparatus including a position detecting unit detecting a contact position at which an input object has touched a touch panel, an area detecting unit detecting a contact area between the touch panel and the input object, and a selecting unit selecting any one of a plurality of objects based on the contact position and the contact area.

Claims

1. An information processing apparatus comprising:

a position detecting unit detecting a contact position at which an input object has touched a touch panel;

an area detecting unit detecting a contact area between the touch panel and the input object; and

a selecting unit selecting any one of a plurality of objects based on the contact position and the contact area.

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

a pressure detecting unit detecting pressure applied by the input object onto the touch panel, and

wherein the selecting unit selects any one of the plurality of objects further based on the pressure.

3. The information processing apparatus according to claim 2,

wherein the selecting unit corrects the contact area using the pressure and selects any one of the plurality of objects based on the contact position and the corrected contact area.

4. The information processing apparatus according to claim 3,

wherein the selecting unit corrects the contact area in a manner that the contact area decreases with increase in the pressure.

5. The information processing apparatus according to claim 1,

wherein the selecting unit selects any one of the plurality of objects further based on a contact history at a time when the input object contacted the touch panel.

6. The information processing apparatus according to claim 5,

wherein the contact history includes a history of the contact position previously detected by the position detecting unit.

7. The information processing apparatus according to claim 6,

wherein the selecting unit corrects the contact position detected by the position detecting unit based on the history of the contact position and selects any one of the plurality of objects based on the contact area and the corrected contact position.

8. The information processing apparatus according to claim 5,

wherein the contact history includes a history of the contact area previously detected by the area detecting unit.

9. The information processing apparatus according to claim 8,

wherein the selecting unit corrects the contact area detected by the area detecting unit based on the history of the contact area and selects any one of the plurality of objects based on the contact position and the corrected contact area.

10. The information processing apparatus according to claim 8,

wherein the selecting unit corrects a threshold associated with each of the plurality of objects based on the history of the contact area and selects any one of the plurality of objects based on the contact position, the contact area, and the corrected threshold.

11. The information processing apparatus according to claim 5,

wherein the contact history includes a history of the pressure previously detected by the pressure detecting unit.

12. The information processing apparatus according to claim 11,

wherein the selecting unit corrects the contact area detected by the area detecting unit based on the history of the pressure and selects any one of the plurality of objects based on the contact position and the corrected contact area.

13. The information processing apparatus according to claim 11,

wherein the selecting unit corrects a threshold associated with each of the plurality of objects based on the history of the pressure and selects any one of the plurality of objects based on the contact position, the contact area, and the corrected threshold.

14. The information processing apparatus according to claim 1,

wherein each of the plurality of objects is associated with a parameter different from a neighboring object, and

the selecting unit selects any one of the plurality of objects based on the parameter associated with each of the plurality of objects, the contact position, and the contact area.

15. An information processing method comprising:

detecting a contact position at which an input object has touched a touch panel;

detecting a contact area between the touch panel and the input object; and

selecting any one of a plurality of objects based on the contact position and the contact area.

16. A program for causing a computer to function as an information processing apparatus, the information processing apparatus including

a position detecting unit detecting a contact position at which an input object has touched a touch panel,

an area detecting unit detecting a contact area between the touch panel and the input object, and

a selecting unit selecting any one of a plurality of objects based on the contact position and the contact area.
