See With Your Tongue
Yes, this is possible. An international team of neuropsychologists has improved a device named "Tongue Display Unit" (TDU) pioneered at the University of Wisconsin in Madison. The device consists of a grid of 144 gold-plated electrodes set in the mouth and able to activate the cerebral cortex, the area of brain normally used for vision, of blind people. In their experiments, blind people were able to "see letters with their tongue."
This system has the potential to replace the Braille alphabet and to vastly improve the quality of life of blind persons. More details, pictures and references are available in this overview.
