Abstract

Blind people face tremendous challenges daily in accessing information while on the move or for matter in communicating with world around them. In order to achieve this challenging task we, in this paper propose a novel cell phone which is designed for blind and is used for managing incoming and outgoing calls, sending and receiving SMS, detect obstacles while on move and indicate the location coordinates of the blind. The call can be made by pressing a key on the Braille keypad which is assigned with a specific contact number in the phone book. The messages are typed into Braille keypad and are processed by microcontroller which converts the Braille letters to English alphabets using the look up table then this SMS is sent via GSM. The voice playback unit provides an audio version of the received SMS. When an emergency switch is pressed the location of the blind is provided via GPS and the GSM will forward this information to the pre fed mobile number stored in the phone book. When the object is detected near to the blind the ultrasonic sensor sends signal to voice playback unit.
