Back propagation Neural Network Proposed Algorithm to learn deaf a Computer Commands by Hand Gestures

Sign language Plays important role in activating the relation between people and computers ,through the activation of the concept of hand movements and provide easier way for people with disabilities (deaf) to express what they want and replace it with their hands.This paper give the overview of proposed backpropagation neural network algorithm to construct a method to identify some of computer tools through hand sign (gesture).
