Braille is a method of producing text by means of raised dots that can be read by touch  A recent development in technology will allow flat computer screens to be made of a material that can be heated in patterns that replicate the patterns used in braille
Since the thermal device will utilize the same symbol system as braille, it follows that anyone who is accustomed to reading braille can easily adapt to the use of this electronic system
People with the tactile ability to discriminate symbols in braille have an ability to discriminate similar patterns on a flat heated surface.
