Title:
TACTILE AND VISUAL FEEDBACK SYNCHRONIZATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/168621
Kind Code:
A9
Abstract:
Provided in the present disclosure are a tactile and visual feedback synchronization method and device, which are used for controlling tactile feedback and visual feedback that accompany a touch-control operation of a user to stay synchronous, so as to reduce the delay of the visual feedback, thereby avoiding the visual experience of lagging. The method comprises: acquiring tangential velocities of touch points during rotation, wherein the touch points are generated by means of a user executing a rotation touch operation within the coverage range of a virtual knob displayed on a touch-control screen, and the touch operation is accompanied by tactile feedback; and according to the tangential velocities, controlling response labels displayed on the touch-control screen to move in sequence, so as to make the tactile feedback stay synchronized with visual feedback produced by the movement of the response labels, wherein the step length of each instance of movement of each response label corresponds to a preset unit angle, and the number of times each response label is moved is determined according to the number of preset unit angles included in a rotation angle of the virtual knob.
