Abstract
A tactile display may comprise an array of pins that may be raised in height relative to one another to represent contours of objects in a graphic image or picture when touched. Various physical attributes may be given to individual pins to represent color or brightness. For example, pins may be heated or cooled to represent cool or warm colors in the original image. Pins may also be vibrated or otherwise enhanced to represent color or brightness information in the original image.
