Abstract

Provided is a three-dimensional (3D) pointing input apparatus which controls a display apparatus. The 3D pointing input apparatus senses a change according to a movement of the 3D pointing input apparatus upon entering a scroll function mode, and maintains a scrolling speed of a screen of the display apparatus at a threshold speed when a movement range of a virtual scroll cursor of the display apparatus, which moves corresponding to the sensed change, is out of a first area. The 3D pointing input apparatus and method may permit a user to effectively and accurately use a scroll function.

Claims

1. A three-dimensional (3D) pointing input apparatus which controls a display apparatus, the 3D pointing input apparatus comprising:

a sensor unit which senses a change according to a movement of the 3D pointing input apparatus; and

a control unit which maintains a scrolling speed of a screen of the display apparatus at a threshold speed when a movement range of a virtual scroll cursor of the display apparatus, which moves corresponding to the sensed change, is out of a first area.

2. The 3D pointing input apparatus of claim 1, wherein the control unit restricts a movement range of a scroll cursor on the screen to be within the first area when the virtual scroll cursor is placed out of the first area.

3. The 3D pointing input apparatus of claim 1, wherein the control unit controls a scrolling speed of the screen according to the sensed change of the 3D pointing input apparatus when the virtual scroll cursor is placed within the first area.

4. The 3D pointing input apparatus of claim 1, wherein the control unit stops the scroll cursor from moving for a predetermined period of time upon entering a scroll function mode.

5. The 3D pointing input apparatus of claim 1, wherein the control unit restricts a movement range of a scroll cursor on the screen to be within a second area when the virtual scroll cursor is placed out of the first area.

6. An input method of a three-dimensional (3D) pointing input apparatus which controls a display apparatus, the input method comprising:

sensing a change according to a movement of the 3D pointing input apparatus upon entering a scroll function mode; and

maintaining a scrolling speed of a screen of the display apparatus at a threshold speed when a movement range of the virtual scroll cursor of the display apparatus, which moves according to the sensed change, is out of a first area.

7. The input method of claim 6, wherein in the maintaining of the scrolling speed of the screen, a movement range of a scroll cursor on the screen is restricted to be within the first area when the virtual scroll cursor is placed out of the first area.

8. The input method of claim 6, further comprising:

varying the movement of a scroll cursor on the screen according the sensed change of the 3D pointing input apparatus when the movement range of the virtual scroll cursor is within the first area.

9. The input method of claim 6, further comprising:

stopping movement of a scroll cursor on the screen for a predetermined period of time upon entering the scroll function mode.
