Tactile Graphing Calculator for the Blind

  • Called the Touch-Graph, the device uses a motor that physically pushes individuals pins to the surface, which create a tactile image.

  • One of the InvenTeam members was inspired to create the invention from a pin-screen toy.

  • The InvenTeam hopes to make the device portable and develop it further, so the visually impaired can use it without assistance.
