Touch panel type operation device, touch panel operation method, and computer program

The touch panel operation device according to 4, wherein:

• the touch coordinate is acquired when the touch-on is detected;
• and
• the controller:
• when the touch-on has been detected, determines whether the acquired touch coordinate is located in the predetermined area in the display area;
• and
• if acquired touch coordinate is located in the predetermined area, executes a predetermined function corresponding to the predetermined area.

A touch panel operation method comprising:

• displaying selectable objects;
• providing a touch panel that is located on a display area of the display device and is configured to accept a touch operation of a user;
• and
• detecting a touch-on, the touch-on being a transition from state at which the touch panel detects the user not touching the touch panel to a state at which the touch panel detects the user touching the touch panel;
• detecting a touch-off, the touch off being a transition from the state at which the touch panel detects the user touching the touch panel to the state at which the touch panel detects the user not touching the touch panel;
• setting a touch-off determination time;
• determining that the touch-off has occurred if the state at which the touch panel detects the user not touching the touch panel has continued for the set touch-off determination time or more after the touch-off was detected;
• when the user is touching the touch panel, acquiring a touch coordinate that is a coordinate of a point on the touch panel that the user has touched;
• selecting a selectable object corresponding to the acquired touch coordinate;
• scroll-displaying on the display device the selected selectable object, based on a displacement of the acquired touch coordinate;
• determining whether the touch coordinate was acquired and displaced just before the touch-off was detected;
• and
• if the touch coordinate was acquired and displaced just before the touch-off was detected, setting the touch-off determination time to be longer than if the touch coordinate was acquired and not displaced just before the touch-off was detected.

A non-transitory computer-readable storage medium storing a computer-executable program for touch panel operation, the program comprising:

• instructions for displaying selectable objects;
• instructions for providing a touch panel that is located on a display area of the display device and is configured to accept a touch operation of a user;
• and
• instructions for detecting a touch-on, the touch-on being a transition from state at which the touch panel detects the user not touching the touch panel to a state at which the touch panel detects the user touching the touch panel;
• instructions for detecting a touch-off, the touch off being a transition from the state at which the touch panel detects the user touching the touch panel to the state at which the touch panel detects the user not touching the touch panel;
• instructions for setting a touch-off determination time;
• instructions for determining that the touch-off has occurred if the state at which the touch panel detects the user not touching the touch panel has continued for the set touch-off determination time or more after the touch-off was detected;
• instructions for, when the user is touching the touch panel, acquiring a touch coordinate that is a coordinate of a point on the touch panel that the user has touched;
• instructions for selecting a selectable object corresponding to the acquired touch coordinate;
• instructions for scroll-displaying on the display device the selected selectable object, based on a displacement of the acquired touch coordinate;
• instructions for determining whether the touch coordinate was acquired and displaced just before the touch-off was detected;
• and
• instructions for, if the touch coordinate was acquired and displaced just before the touch-off was detected, setting the touch-off determination time to be longer than if the touch coordinate was acquired and not displaced just before the touch-off was detected.
