Ideas For Visually Impaired: The Metro Dot
A bracelet type transportation card in Braille, The Metro Dot, is a fresh solution, that has been worked out for the visually impaired people. The device can easily receive subway information and inform the user about the needed station or the number of stations left by touch. Being sent to the subway’s receiver antenna, the electronic signals are caught by the bracelet and are sent to the surface to make a Braille pattern on the silicon rubber surface.
