USING TACTILE FEEDBACK TO PROVIDE SPATIAL AWARENESS
First Claim
1. A method, comprising:
- receiving a tactile feedback map based on an image, wherein the tactile feedback map stores a spatial location of at least one object in the image and at least one tactile sensation associated with the object;
receiving a position of user contact on a touch screen;
identifying a tactile sensation by correlating the position of the user contact to a location within the tactile feedback map; and
generating a first electrical signal corresponding to the tactile sensation on at least one electrode associated with the touch screen.

Abstract
An image capturing device may be combined with a touch screen to generate a tactile map of an environment. The image capturing device captures an image of the environment which is then processed and used to correlate a point of user contact on a touch screen to a particular tactile sensation. The touch screen may then generate an electric signal (i.e., tactile feedback) corresponding to the tactile sensation which is felt by a user contacting the touch screen. By using the electrical signal as tactile feedback (e.g., electrovibration), the user may determine relative spatial locations of the objects in the environment, the objects'"'"' physical characteristics, the distance from the objects to the image capturing device, and the like.
