Abstract

A haptic feedback method includes providing a user with an image that is updated based on a collision event, generating collision data including a type of the collision event and an impulse amount, generating a haptic pattern based on the collision data, and generating a vibration based on the haptic pattern.

Claims

1. A haptic feedback method, the method comprising:

providing a user with an image that is updated based on a collision event;

generating collision data including a type of the collision event and an impulse amount;

generating a haptic pattern based on the collision data; and

generating vibration based on the haptic pattern.

2. The method of claim 1, further comprising:

receiving an input from the user,

wherein the collision event is generated based on the user input.

3. The method of claim 2, further comprising:

generating an event based on the user input; and

determining whether the generated event corresponds to a collision event.

4. The method of claim 1, wherein a form of the haptic pattern is determined based on the type of the collision event, and the haptic pattern has a maximum strength associated with the impulse amount.

5. The method of claim 1, wherein a form of the haptic pattern is determined based on the type of the collision event, and the haptic pattern has a duration time associated with the impulse amount.

6. The method of claim 1, wherein the impulse amount corresponds to one of a depth of collision, a collision time, a force of collision, a torque of collision, a variance in momentum of a collision target, a distance that the collision target or an elastic object is pulled, a distance that the collision target or the elastic object is pressed, a mass of the collision target, a collision velocity, a direction of a movement of the collision target, a distance of a movement of the collision target, a collision angle, a stiffness of the collision target, and a pressure applied on the collision target.

7. The method of claim 1, wherein the haptic pattern is formed of a rising part in which a strength is gradually increased, a flat part in which the strength is constant, and a falling part in which the strength is gradually decreased.

8. The method of claim 1, wherein the type of the collision event corresponds to one of a collision between hard bodies, a collision between a hard body and a soft body, a collision between a hard body and a soft body on a hard body, and a transformation of an elastic body.

9. A non-transitory machine-readable storage medium storing a program causing a processor to execute a haptic feedback method, the method comprising;

providing a user with an image that is updated based on a collision event;

generating collision data including a type of the collision event and an impulse amount;

generating a haptic pattern based on the collision data; and

generating vibration based on the haptic pattern.

10. A haptic feedback apparatus, the apparatus comprising:

a display unit which provides a user with an image that is updated based on a collision event;

a controller which generates collision data including a type of the collision event and an impulse amount, and which generates a haptic pattern based on the collision data; and

an actuator which generates vibration based on the haptic pattern.

11. The apparatus of claim 10, further comprising:

a sensor unit which detects an input of the user,

wherein the collision event is generated based on the user input.

12. The apparatus of claim 11, wherein the controller

generates an event based on the user input, and

determines whether the generated event corresponds to a collision event.

13. The apparatus of claim 10, wherein a form of the haptic pattern is determined based on the type of the collision event, and the haptic pattern has a maximum strength associated with the impulse amount.

14. The apparatus of claim 10, wherein a form of the haptic pattern is determined based on the type of the collision event, and the haptic pattern has a duration time associated with the impulse amount.

15. The apparatus of claim 10, wherein the impulse amount corresponds to one of a depth of collision, a collision time, a force of collision, a torque of collision, a variance in momentum of a collision target, a distance that the collision target or an elastic object is pulled, a distance that the collision target or the elastic object is pressed, a mass of the collision target, a collision velocity, a direction of movement of the collision target, a distance of a movement of the collision target, a collision angle, a stiffness of the collision target, and a pressure applied on the collision target.

16. The apparatus of claim 10, wherein the haptic pattern is formed of a rising part in which a strength is gradually increased, a flat part in which the strength is constant, and a falling part in which the strength is gradually decreased.

17. The apparatus of claim 10, wherein the type of the collision event corresponds to one of a collision between hard bodies, a collision between a hard body and a soft body, a collision between a hard body and a soft body on a hard body, and a transformation of an elastic body.
