Title:
METHOD FOR GENERATING VIBROTACTILE TRAVELING WAVE FOR ENABLING VIBROTACTILE TRAVELING WAVE BY SEQUENTIALLY ACTUATING PLURALITY OF ACTUATORS WHILE CHANGING FREQUENCIES ACCORDING TO VELOCITY OF VIRTUAL OBJECT, WHEREIN DETECTED LOCATION OF VIBROTACTILE STIMULATION CHANGES CONTINUOUSLY
Document Type and Number:
WIPO Patent Application WO/2013/073912
Kind Code:
A1
Abstract:
According to a method of the present invention, an electronic device comprising at least two actuators detects a vibrotactile traveling wave event, which occurs due to shifting of a touch signal or shifting of a graphic object, determines therefrom location shift information of the virtual object, divides a movement track of the virtual object into at least three, and outputs a vibrotactile traveling signal with respect to each of the track portions by means of different actuators, wherein different driving voltages are applied to each of the actuators at a center portion of the track on which the virtual object moves and thereby generating an area in which the location of vibrotactile stimulation that is detected changes continuously, thereby providing a variety of haptic effects that change velocity, acceleration, and direction, among others, in accordance with the movement of the vibrotactile traveling wave event.
