Abstract: As an assorted nation with numerous religion tongues, India has attempted to embrace an official, institutionalized gesture based communication. Where as in Indo-Pakistani communication through signing, is viewed as the prevalent sort utilized in South Asia. Many who are deaf or hard of hearing rely on sign language, to communicate. However the estimation of sign language are very unsophisticated and definitions of what counts as proficiency that varies depends on many factors. There are many existing systems which use shape parameters like orientation, palm centroid ,data gloves with 5 accelerometer sensors , and optical markers which reflect infrared light to recognise hand gestures of sign language. Background subtraction techniques used in these systems are K-means clustering ,boundary counters, Eigen backgrounds using Eigen values and wireless technology and bluetooth for connecting software for transmitting recognised hand gesture signals. They are not cost effective but, the accuracy is not met to the need. Whereas, In our proposed system we concentrate mainly to convert hand gestures to text using contour tracing technique to recognise hand gestures using normal webcam. The semantics are classified by support vector machine with trained datasets. The recognised hand gestures are displayed as text. Our main objective is to resolve the problem of facing interviewer for vocally impaired individuals. This helps them to build their confidence and eradicate their inferiority complex compared to other methods.
