Real time sign language interpreter

Sign Language is a medium for communication for many disabled people. The sign language recognition has many applications including gesture controlled activities like human computer interaction, gesture controlled home appliances and other electronic devices and many applications that uses gesture as the trigger input. The most important application is it provides a communication aid for deaf and dumb people. The system for sign language recognition for deaf and dumb people is implemented in ARM CORTEX A8 processor board using convex hull algorithm and template matching algorithm. Image is obtained using webcam. This hand sign image is converted to text so as to develop a communication between normal and deaf and dumb people. Open CV is the software tool that provides the support with image processing techniques. The system converts sign language to text for deaf and dumb people to communicate with normal people. Moreover the system is used to control devices like Robot, Car Audio Systems, home appliances etc.
