Operation control apparatus, operation control method, and computer program
First Claim
1. An operation control apparatus comprising:
- a detection unit configured to detect contact of an operation tool with a display surface of a display unit;
a contact determination unit configured to determine a contact state of the operation tool with the display surface based at least in part on the detection result by the detection unit;
a contact area recognition unit configured to recognize, when the contact determination unit determines that the operation tool is in contact with the display surface, a contact area on which the operation tool contacts the display surface; and
an operation determination unit configured to determine, from a plurality of operation processing that are associated with an act of the operation tool in contact with the display surface, an operation processing to be executed, based at least in part on a size of the contact area recognized by the contact area recognition unit, the operation determination unit being configured to determine to execute scroll processing for scrolling a screen displayed on the display unit if the size of the contact area is less than a size threshold value and to determine to execute cursor movement processing for moving a cursor indicating a display position on the display unit if the size of the contact area is greater than the size threshold value.

Abstract
An operation control apparatus is provided which includes a detection unit for detecting contact of an operation tool with a display surface of a display unit, a contact determination unit for determining a contact state of the operation tool with the display surface based on the detection result by the detection unit, a contact area recognition unit for recognizing, in the case where it is determined by the contact determination unit that the operation tool is in contact with the display surface, a contact area where the operation tool is in contact with the display surface, and an operation determination unit for determining, from a plurality of operation processing associated with an act of the operation tool in contact with the display surface, an operation processing to be executed, based on a size of the contact area recognized by the contact area recognition unit.

6. An operation control method, comprising acts of:
-
detecting contact of an operation tool with a display surface of a display unit; determining a contact state of the operation tool with the display surface based at least in part on the detection result; recognizing, when the operation tool is in contact with the display surface, a contact area on which the operation tool contacts the display surface; and determining, from a plurality of operation processing that are associated with an act of the operation tool in contact with the display surface, an operation processing to be executed, based at least in part on a size of the recognized contact area, the determining comprising determining to execute scroll processing for scrolling a screen displayed on the display unit if the size of the contact area is less than a size threshold value and determining to execute cursor movement processing for moving a cursor indicating a display position on the display unit if the size of the contact area is greater than the size threshold value.

7. At least one storage device having encoded thereon instructions which, when executed by a computer, perform a method for causing the computer to function as an operation control apparatus, the method comprising acts of:
-
determining, based at least in part on a detection result by a detection unit for detecting contact of an operation tool with a display surface of a display unit, a contact state of the operation tool with the display surface; recognizing, when the operation tool is in contact with the display surface, a contact area on which the operation tool contacts the display surface; and determining, from a plurality of operation processing that are associated with an act of the operation tool in contact with the display surface, an operation processing to be executed, based at least in part on a size of the recognized contact area, the determining comprising determining to execute scroll processing for scrolling a screen displayed on the display unit if the size of the contact area is less than a size threshold value and determining to execute cursor movement processing for moving a cursor indicating a display position on the display unit if the size of the contact area is greater than the size threshold value.
