The sign language is an important method of communication for deaf and dumb people. As sign language is a well-structured paradigm, each gesture has a meaning assigned to it. Gestures or the Sign language is the combination of orientations, movement of the hands, arms or body and facial expressions. The communication of deaf and dumb people is not easily predicted by the common people. In order to overcome the barrier in communication an advanced system is required. A Security assistive system is proposed, comprising of a Tri-axial accelerometer sensor through which the gestures are recognized and correspondingly for each gesture the threshold value and particular voice output is obtained. Vibration sensor continuously senses the state of a person and it sends the message to the end user when it is vibrated.The developed system aids the deaf and dumb people to communicate with the normal people without the requirement of an interpreter. It helps the deaf and dumb people to act independently at the emergency conditions and also lowers the communication barrier.
