Contact operation determination apparatus, contact operation determination method, and program

A contact operation determination method comprising:

• setting a first area in a contact detection area;
• setting, in the contact detection area, a first area, and a second area that surrounds the first area so as to have a width greater than or equal to a predetermined distance from a contact starting point to a contact end point, the second area being used to discriminate between a tap operation and a flick operation;
• determining, when the contact end point is detected in the first or second area after the contact starting point has been detected in the second area, that the flick operation has been performed;
• and
• determining, when the contact end point is detected within an area of the predetermined distance from the contact starting point after the contact end point has been detected in the first area, that the tap operation has been performed.

A program for causing a computer to perform a contact operation determination method comprising:

• setting a first area in a contact detection area;
• setting, in the contact detection area, a first area, and a second area that surrounds the first area so as to have a width greater than or equal to a predetermined distance from a contact starting point to a contact end point, the second area being used to discriminate between a tap operation and a flick operation;
• determining, when the contact end point is detected in the first or second area after the contact starting point has been detected in the second area, that the flick operation has been performed;
• and
• determining, when the contact end point is detected within an area of the predetermined distance from the contact starting point after the contact end point has been detected in the first area, that the tap operation has been performed.
