Abstract
A system and method for a touch display system. The a touch display system includes: a flat touch display assembly including a matrix of flat Braille pixels, wherein each flat Braille pixel is operable to be placed in one of two states. A heating source is selectively connected to each flat Braille pixel. A cooling source selectively connected to each flat Braille pixel. The flat Braille pixels are configured to represent images to touch by selective heating and cooling thereof. In one embodiment, the above described display can be used in combination with software that automatically converts text to Braille which is displayed using the flat touch display assembly.
Claims13
A touch display system comprising:
- a flat touch display assembly comprising a matrix of flat Braille pixels, wherein each flat Braille pixel is operable to be placed in one of two states while remaining flat in both states, the states including a first state in which the flat pixel has a first temperature and a second state in which the flat pixel has a second temperature lower than the first temperature;
- a heating source selectively connected to each flat Braille pixel to render the pixel into the first state;
- and
- a cooling source selectively connected to each flat Braille pixel to render the pixel into the second state.
A method comprising:
- heating a first plurality of flat Braille pixels in a flat tactile display to heat a flat Braille pixel without rendering the Braille pixel non-flat;
- and
- cooling a second plurality of flat Braille pixels in said flat tactile display;
- wherein
- said heating and said cooling forms a smooth tactile image to touch.
