Abstract

Provided are a pointing apparatus capable of providing haptic feedback, and a haptic interaction system and method using the same. The pointing apparatus includes a wireless communication unit, a controller, and a haptic stimulator. The wireless communication unit receives an event including haptic output information through wireless communication with the outside. The controller generates a control signal for reproducing a haptic pattern corresponding to the haptic output information. The haptic stimulator reproduces the haptic pattern by means of the control signal. Thus, it is possible to increase the performance and usability of a user interface of a user terminal including a touch screen.

Claims

2. The pointing apparatus of claim 1, further comprising:

a battery serving as a power supply unit; and

a charge terminal charging the battery.

3. The pointing apparatus of claim 1, further comprising:

a sound output unit reproducing a sound effect corresponding to the haptic pattern.

4. The pointing apparatus of claim 1, further comprising:

a microphone and a speaker providing a sound input/output function for a voice call or a voice command.

5. The pointing apparatus of claim 3, wherein the controller controls the sound output unit to output an alarm or alarm sound.

6. The pointing apparatus of claim 1, wherein the event is generated in response to an operation of the pointing apparatus on a touch screen.

7. The pointing apparatus of claim 1, wherein the haptic stimulator comprises at least one of:

a rotary vibrator generating a vibration by means of a first mass that is rotated by the control signal; and

a linear vibrator generating an impact and a vibration by means of a second mass that linearly moves upward and downward by a magnetic field corresponding to the control signal.

8. The pointing apparatus of claim 7, wherein the first mass is eccentrically attached to a rotation axis of the rotary vibrator to generate the vibration through eccentric rotational motion.

9. The pointing apparatus of claim 7, wherein when a target on a touch screen is selected or released, the controller generates one of an impact of the second mass on the top side, a sequential impact of the second mass on the top side and the bottom side, and a sequential impact of the second mass on the bottom side and the top side.

10. The pointing apparatus of claim 7, wherein when a target on a touch screen is selected or released, the controller generates a vibration of the first mass or the second mass.

11. The pointing apparatus of claim 7, wherein the controller increases the input cycle of the control signal in proportion to the moving speed of a pointer.

12. The pointing apparatus of claim 7, wherein the controller increases the vibration intensity of the rotary vibrator in proportion to the moving speed of a pointer.

13. The pointing apparatus of claim 7, wherein when a pointer moves by the unit of a movement distance, the controller generates a short vibration of the rotary vibrator or a sequential impact of the linear vibrator on the bottom side and the top side.

14. The pointing apparatus of claim 7, wherein the controller gradually increases the intensity of a vibration while the size of a window is maximized.

15. The pointing apparatus of claim 7, wherein the controller gradually reduces the intensity of a vibration while the size of a window is minimized.

16. The pointing apparatus of claim 7, wherein the controller increases the intensity of a vibration in proportion to the deviation distance of a pointer from a predetermined region.

17. The pointing apparatus of claim 7, wherein when a window on a touch screen is closed, the controller generates one of a gradually weakening vibration, a short vibration, and a sequential impact of the linear vibrator on the bottom side and the top side for a predetermined time.

18. The pointing apparatus of claim 7, wherein when a new pop-up menu is generated on a touch screen, the controller generates one of a short vibration, and a sequential impact of the linear vibrator on the bottom side and the top side for a predetermined time.

19. The pointing apparatus of claim 7, wherein when the number of objects selected by the pointing apparatus is varied on a touch screen, the controller generates a sequential impact of the second mass on the top side and the bottom side.

20. The pointing apparatus of claim 19, wherein the objects selected by the pointing apparatus on the touch screen is selected from the group consisting of a character in a document, an icon, a folder and a file which is selectable one or more.

21. The pointing apparatus of claim 7, wherein when the pointing apparatus is disposed on a button having a predetermined purpose, the controller generates a repetitive impact of the second mass on the top side or the bottom side.

22. The pointing apparatus of claim 21, wherein the controller collides the second mass against only one of the top side and the bottom side, and gradually moves the second mass so that it cannot collide with the opposite side when it moves to the opposite side.

23. The pointing apparatus of claim 7, wherein when the size or angle of a figure are varied on a touch screen as much as a reference unit value by the pointing apparatus, the controller generates a sequential impact of the second mass on the top side and the bottom side.
