A Device to Help Blind People Draw

Still in the concept stage, the Touch Color is a device that would allow visually impaired people to create two-dimensional art:
This innovative device comprises a Rainbow Picker in a form of a scroll wheel, which contains Braille dots that allows blind people to select a color from 24 available. After selecting a color, this device differentiates the colors by generating varied temperatures through LED bulbs. Then the user can paint on a thermal art board by using their fingers and the thermal-color display technology keeps the track of the lines and colors the blind artist is using.
