Apparatus and method of providing fingertip haptics of visual information using electro-active polymer for image display device
First Claim
1. An apparatus providing fingertip haptics of visual information using electro-active polymer for an image display device, the apparatus comprising:
- a sensing unit which outputs a detecting signal by detecting a user'"'"'s finger contacting a touch panel;
a pattern generating unit which generates a pattern signal of haptic information from the visual information based on the detecting signal; and
a control unit which moves the electro-active polymer based on the detecting signal from the sensing unit and deforms the electro-active polymer based on the pattern signal from the pattern generating unit.
