This paper aims at developing a communication device suitable for people with Deaf-Blindness, as well as visual impairment or hearing loss. Our approach focuses on designing a low cost, portable and standalone communicating device that converts Braille to Text, for people suffering from Deaf-Blindness. Here two modes of communication can be implemented i.e. short distance communication (Face to Face) and long distance communication. For short distance communication, Braille keypad is used as an input and an LCD display as an output respectively. For long distance communication, the GSM module is interfaced to send the message to a remote receiver. In order to reduce the cost, the braille keyboard is replaced with push buttons with same functionalities. A vibration band is introduced to notify the user whenever the message is sent.
