METHOD FOR USING THE GPU TO CREATE HAPTIC FRICTION MAPS

摘要

A haptics rendering system comprises: a display device having a display screen and one or more haptic feedback mechanisms associated with at least one tactile output peripheral; and a graphics processing unit (GPU) communicatively coupled to the display device. The GPU: receives one or more portions of display image software code for a three dimensional display image; generates a three dimensional (3D) visual output of the display image for display on the display device; and concurrently generates one or more specific friction maps to provide haptic feedback of depth and/or texture associated with specific portions of the display image that comprise at least one portion having at least one of a different depth and a different texture than other portions of the display image. The GPU renders the display image and the friction map from a same set of 3D commands within the display image software code.

1. An information handling system comprising:
a processor capable of executing software code; a display device having a display screen; one or more haptic feedback mechanisms associated with at least one tactile response peripheral and which generate one or more sensations associated with a display image; and a graphics processing unit (GPU) communicatively coupled to the processor and to the display device and which:
receives one or more portions of the software code corresponding to the display image;generates one of a two dimensional (2D) and a three dimensional (3D) visual output of the display image for display on the display device, wherein the three dimensional visual output contains a height, a width and a depth dimension relative to a 2D plane; andconcurrently generates one or more specific friction maps to provide haptic feedback associated with specific portions of the display image that comprise at least one portion having at least one of a different depth and a different texture than other portions of the display image.
