Human Computer Interface for Physically Impaired

Human Computer Interface (HCI) is a trend-in technology. HCI refers to means of communication between a user and a computer via various input/output devices. Working in this field, we've developed a system to produce an answer to the limb disabled individuals to navigate the computers. Different algorithms are enforced in this paper, to estimate the gaze of the user to acknowledge the reference key. Due to the recent advancements within the field of Computer Vision and Object detection and tracking, computers are currently ready to understand the world with a perspective corresponding to humans. The head involuntarily follows the field of vision, i.e., you progress your head wherever your eyes are centred. Exploiting this biological feature of the autonomous and involuntary movement of the head, any of the facial expressions (eyes, nose, jaw, etc.) is sufficient to confirm what the user desires to concentrate on, and also the mouse indicator would be stirred consequently. The system, once enforced and fine-tuned consistent with the user, would alter a swish navigation of the mouse indicator across the viewport of the screen, altogether eliminating the requirement of the mouse.
