Claim:
1. A haptic feedback method, the method comprising: obtaining information on an impulse amount range of collisions from an application stored in a memory; matching the impulse amount range and a strength range of haptic patterns; providing a user with an image of the application that is updated based on a collision event; obtaining information on the collision event; generating a haptic pattern based on the information on the collision event; and generating vibration based on the haptic pattern, wherein the collision event is caused by a collision between a first object and a second object in the image, and wherein generating the haptic pattern includes: determining a maximum strength of the haptic pattern within the strength range corresponding to an impulse amount of the collision within the impulse amount range; if the collision between the first object and the second object is a collision between hard bodies, generating a rectangular haptic pattern; and if the collision between the first object and the second object is a collision between soft bodies or a collision between a hard body and a soft body, generating a triangular haptic pattern.
