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
Eventually it will be possible to train people to read braille by first training them in the use of the thermal screen.
