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.
