First Claim
Patent Images
1. A haptic device comprising:
- a display configured to display an image;
a haptic output device configured to output a haptic effect, the haptic effect configured to simulate a texture of the image or a contour of the image in three dimensions;
a processor coupled to the display and the haptic output device; and
a memory device including instructions executable by the processor to cause the processor to;
detect a movement in one or more directions across a surface of the display;
determine a plurality of haptic-effect maps corresponding to the image, each haptic-effect map of the plurality of haptic-effect maps specifying an intensity of the haptic effect at different locations of the display and being associated with a different direction of movement across the surface; and
select a haptic-effect map from among the plurality of haptic-effect maps as a function of a direction of the movement across the surface of the display; and
modulate the intensity of the haptic effect based on the selected haptic-effect map and the direction of the movement across the surface of the display.

Abstract
A haptic device includes a display configured to display an image, a haptic output device configured to generate a haptic effect to a user when the user interacts with the display, and a processor configured to receive information related to the image displayed on the display. The processor is also configured to create a friction based haptic effect map associated with the image displayed on the display, and generate a signal to the haptic output device to output the haptic effect when the user interacts with the display when the image is displayed on the display, the haptic effect being configured to simulate a feel of the image in three dimensions.

7. A method comprising:
-
receiving information associated with an image displayed on a display; detecting a movement in one or more directions across a surface of the display; determine a plurality of haptic-effect maps corresponding to the image, each haptic-effect map of the plurality of haptic-effect maps specifying an intensity of a haptic effect at different locations of the display and being associated with a different direction of movement across the surface; selecting a haptic-effect map from among the plurality of haptic-effect maps as a function of a direction of the movement across the surface of the display; outputting the haptic effect via a haptic output device, the haptic effect being configured to simulate a texture of the image or a contour of the image in three dimensions; and modulating the intensity of the haptic effect based at least in part on the selected haptic-effect map and the direction of the movement across the surface of the display. - View Dependent Claims (8, 9)
