ELECTRONIC DEVICE AND METHOD FOR PROVIDING TACTILE STIMULATION

摘要

A method for providing tactile stimulation is applied in an electronic device. The electronic device includes a touch-sensitive screen and a tactile stimulation multilayer connected to the touch-sensitive screen. The tactile stimulation multilayer includes a number of electrodes. The method includes follow steps: detecting at least one touch point on the touch-sensitive screen; determining position information of each touch point and an occurrence time of touching each touch point; determining electrodes each corresponding to the position information of one touch point and energizing the determined electrodes; extracting a number of successively detected touch points and determining whether a slide operation is exerted on the touch-sensitive screen; calculating an anticipated trajectory of the slide operation if a slide operation is exerted on the touch-sensitive screen; and determining a number of electrodes each corresponding to position information of one touch point forming the anticipated trajectory and energizing the determined electrodes.
