Abstract

An information processing apparatus includes a display unit; a touch panel configured to detect a touch position at which a touch operation is performed on the display unit; a function setting module configured to set at least one area of a first area functioning as a touch screen and a second area functioning as a precision touch pad with respect to a touch panel area where the touch panel is formed; and a polling rate setting module configured to raise a polling rate in an area where the second area is set in the touch panel area when the second area is set for the touch panel area.

First claim

The invention claimed is:

1. An information processing apparatus comprising:
a display unit;
a touch panel that detects a touch position at which a touch operation is performed on the display unit;
a function setting module that sets at least one area of a first area functioning as a touch screen and a second area functioning as a precision touch pad with respect to a touch panel area where the touch panel is formed; and
a polling rate setting module that raises a polling rate in an area where the second area is set in the touch panel area when the second area is set for the touch panel area;
a sensor device that determines a posture of the apparatus;
a posture detecting module that detects a posture of the apparatus based on posture information related to the posture of the apparatus acquired by the sensor device;
a mode determining module that determines a mode in which the apparatus is used based on the detected posture, wherein the determined mode is a book mode or a clamshell mode;
a display processing module that displays a virtual precision touch pad, which is the precision touch pad as a virtual pad, at a position in the touch panel area according to the determined mode,
wherein, when the mode determining module determines a book mode, the display processing module displays a virtual precision touch pad at a preset position in the touch panel area, wherein the preset position is based on information acquired by the sensor device as a position corresponding to a thumb of a user; and
a touch operation determining module that determines whether the touch operation is an operation on which a process should be performed based on a magnitude relationship of contact information with respect to a threshold, the contact information being information related to contact between an operation medium and the touch panel that is acquired when the touch operation by the operation medium is performed.

2. The information processing apparatus according to claim 1 , wherein the polling rate setting module raises the polling rate in the area where the second area is set in the touch panel area up to at least 125 Hz.

3. The information processing apparatus according to claim 1 , wherein the polling rate setting module restores the polling rate in the area where the second area is set in the touch panel area when setting of the second area is canceled.

4. The information processing apparatus according to claim 1 , further comprising:
a threshold setting module that changes the threshold in the area where the second area is set in the touch panel area to a value different from the threshold in another area in the touch panel area when the second area is set for the touch panel area.

5. The information processing apparatus according to claim 4 , wherein the threshold setting module restores the threshold in the area where the second area is set in the touch panel area when setting of the second area is canceled.

6. A control method for an information processing apparatus comprising a display unit and a touch panel that detects a touch position at which a touch operation is performed on the display unit, the control method comprising:
setting, by a function setting module, at least one area of a first area functioning as a touch screen and a second area functioning as a precision touch pad with respect to a touch panel area where the touch panel is formed;
raising, by a polling rate setting module, a polling rate in an area where the second area is set in the touch panel area when the second area is set for the touch panel area;
determining, by a sensor device, a posture of the apparatus;
detecting, by a posture detecting module, a posture of the apparatus based on posture information related to the posture of the apparatus acquired by the sensor device;
determining, by a mode determining module, a mode in which the apparatus is used based on the detected posture, wherein the determined mode is a book mode or a clamshell mode;
displaying, by a display processing module, a virtual precision touch pad, which is the precision touch pad as a virtual pad, at a position in the touch panel area according to the determined mode,
wherein, when the mode determining module determines a book mode, the display processing module displays a virtual precision touch pad at a preset position in the touch panel area, wherein the preset position is based on information acquired by the sensor device as a position corresponding to a thumb of a user; and
determining, by a touch operation determining module, whether the touch operation is an operation on which a process should be performed based on a magnitude relationship of contact information with respect to a threshold, the contact information being information related to contact between an operation medium and the touch panel that is acquired when the touch operation by the operation medium is performed.

7. An information processing apparatus comprising:
a display unit;
a touch panel that detects a touch position at which a touch operation is performed on the display unit;
a function setting module that sets at least one area of a first area functioning as a touch screen and a second area functioning as a precision touch pad with respect to a touch panel area where the touch panel is formed; and
a polling rate setting module that raises a polling rate in an area where the second area is set in the touch panel area when the second area is set for the touch panel area;
a sensor device that determines a posture of the apparatus;
a posture detecting module that detects a posture of the apparatus based on posture information related to the posture of the apparatus acquired by the sensor device;
a mode determining module that determines a mode in which the apparatus is used based on the detected posture, wherein the determined mode is a book mode or a clamshell mode;
a display processing module that displays a virtual precision touch pad, which is the precision touch pad as a virtual pad, at a position in the touch panel area according to the determined mode,
wherein, when the mode determining module determines a clamshell mode, the display processing module displays a virtual precision touch pad at a preset position in the touch panel area, wherein the preset position is based on information acquired by the sensor device as corresponding to a position, toward the user, that facilitates performing a touch operation; and
a touch operation determining module that determines whether the touch operation is an operation on which a process should be performed based on a magnitude relationship of contact information with respect to a threshold, the contact information being information related to contact between an operation medium and the touch panel that is acquired when the touch operation by the operation medium is performed.

8. The information processing apparatus according to claim 7 , wherein the polling rate setting module raises the polling rate in the area where the second area is set in the touch panel area up to at least 125 Hz.

9. The information processing apparatus according to claim 7 , wherein the polling rate setting module restores the polling rate in the area where the second area is set in the touch panel area when setting of the second area is canceled.

10. The information processing apparatus according to claim 7 , further comprising:
a threshold setting module that changes the threshold in the area where the second area is set in the touch panel area to a value different from the threshold in another area in the touch panel area when the second area is set for the touch panel area.

11. The information processing apparatus according to claim 1
