A virtual reality platform is presented for teaching simple shapes and alphabetic letters to blind students. By using this technology the teacher could be able to present special letters and shapes on a virtual plate. A virtual plate displays shapes and letters that the blind user can “feel” using a haptic robot that display force from the computer to him/her. This method has been tested in a blind school and the result presented in a paper. Results showed that the virtual environment is a useful educational tool for blind students in case of money and time. As the results showed a blind student with a an average IQ can learn the letter or shape by up to 15 times of repetition and after that he/she can write or draw the shape or letter on the paper.
