Abstract

An apparatus, method and computer program product cooperate to prepare frame information that causes a frame to be displayed on a display unit at an operation target position that is an offset of a predetermined distance on said display from an operation detection position. The frame information is then sent to the display unit for displaying the frame. A recognition unit detects the operation detection position in response to a contact made with the display. The display may be a touch panel or a proximity detection display, and the frame has a shape with an interior portion, a border portion and an exterior portion.

Claims

1. A display controller, comprising:

an interface configured to send frame information that causes a display unit to display a frame; and

a controller that is connected to said interface and sends said frame information to said display so said frame is positioned on said display at an operation target position that is offset by a predetermined distance on said display from an operation detection position.

2. The display controller of claim 1, further comprising:

a recognition unit that detects said operation detection position in response to a contact made with the display at said operation detection position.

3. The display controller of claim 1, further comprising:

a recognition unit that detects said operation detection position based on proximity of a selection device to said display unit without directly contacting the display unit.

4. The display controller of claim 1, further comprising

a recognition unit that detects an abstracted touch event.

5. The display controller of claim 1, further comprising:

a computer readable storage device that stores at least a part of said frame information as cursor definition data that defines a shape and a size of said frame.

6. The display controller of claim 5, wherein:

said computer readable storage device also stores an initial value and a current value of the offset.

7. The display controller of claim 6, wherein:

said frame has a border in a ring shape, wherein said ring shape being at least one of a continuous ring shape and a ring shape with gaps.

8. The display controller of claim 6, wherein:

said frame has a border in a box shape.

9. The display controller of claim 1, further comprising:

a recognition unit that detects a touch event, wherein

said controller sends the frame information to the display in response to said touch event.

10. The display controller of claim 9, wherein

the frame remains displayed after a conclusion of the touch event.

11. The display controller of claim 9, wherein

said recognition unit detects when the touch event includes moving a contact point along a surface of said display unit, and

said controller causes the frame to move along with the contact point on the display unit while maintaining the offset at the predetermined distance.

12. The display controller of claim 11, wherein

said controller maintains said offset in response to the contact point being dragged side-to-side on the display unit.

13. The display controller of claim 9, wherein

said recognition unit recognizes a second touch event that follows the touch event, and

said controller moves the frame at a rate that varies according to a gap between the operation detection position and the operation target position at a start of frame movement.

14. The display controller of claim 9, wherein

said recognition unit recognizes a second touch event that comes after the touch event, and

said controller moves the frame at a rate that is a function of a gap relative to a threshold.

15. The display controller of claim 14, wherein

said recognition unit recognizes a second touch event that comes after the touch event, and

said controller moves the frame on the display unit at a rate that is different for respective contact points at

an interior of said frame,

on said frame, and

an exterior of said frame.

16. The display controller of claim 9, wherein

said recognition unit successively recognizes a second touch event, and a third touch event that both follow the touch event, and

in response to the third touch event, said controller moves the frame over or around a contact position of the third touch event regardless of the offset.

17. The display controller of claim 16, wherein

said third touch event being one of a multi-tap, a change in pressure, and a flick.

18. The display controller of claim 1, wherein:

said controller locks a display position about a displayed object.

19. A display control method, comprising:

preparing at a display controller frame information that causes a frame to be displayed on a display unit at an operation target position that is offset at a predetermined distance on said display unit from an operation detection position; and

sending said frame information to the display unit that displays the frame.

20. A computer readable storage device having computer readable instructions that when executed by a computer processor cause the computer processor to perform a method comprising:

preparing at a display controller frame information that causes a frame to be displayed on a display unit at an operation target position that is offset at a predetermined distance on said display unit from an operation detection position; and

sending said frame information to the display unit that displays the frame.
