The user interface of the personal computer has evolved from a text-based command line to a graphical interface with keyboard and mouse inputs. Undoubtedly, human-computer interaction will continue to evolve towards more natural forms of input. Popular culture has long viewed computer vision along with recognition of the user in front it and recognition of his/her visual gestures as one of the future ways we will interact with our computers. Vision has the potential of carrying a wealth of information in a non-intrusive manner and at a low cost; therefore it constitutes a very attractive sensing modality for developing Intelligent Schemes for Human Computer Interaction. With an aim to learn about computer systems that analyze images automatically, determining what the computer sees or recognizes, we have proposed a model, which not only recognizes the face of the user who is sitting in front of the system but also recognizes his/her facial expressions and hand gestures, thus providing new interfaces for users in Human Computer Interaction.
