Touch Color Helps Blind People to Draw

The Touch Color concept has been specially designed to make blind people able to draw and admire colorful digital pictures. 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.

  1. Nice idea but I think the creator needs to study the practicalities of using Braille.

    It's usually read with the first finger, and no, you can't easily substitute the thumb [similar to asking someone to write with their non-dominant hand] especially when the Braille is sideways as in the picture of the scroll wheel being held. Any dots that they managed to discern with the thumb would make absolutely no sense.

    In addition, they have the shorthand letters wrong, instead of R for red, they have a V, and instead of O for orange, they have S.

    If the way the scroll wheel was changed to be used flat, with the hand over the top [like a computer mouse] and the Braille properly aligned to be felt the right way under the index finger [and had correctly labelled colours] this might work. Perhaps.
