GazePointer: A real time Mouse Pointer Control implementation based on Eye

Gaze Tracking

Introduction:The field of Human-Computer Interaction (HCI) has witnessed a tremendous growth in the past decade. The advent of tablet PCs and cell phones allowing touch-based control has been hailed warmly. The researchers in this field have also explored the potential of 'eye-gaze' as a possible means of interaction. Some commercial solutions have already been launched, but they are as yet expensive and offer limited usability. This project strives to develop a low cost real time system for eye-gaze based human-computer interaction.

Objectives:Developing an algorithm that will acquire, process and analyze video frames and extract the following:

o Faceo Head Postureo Eyes

Detecting center of Iris (Pupil).Designing an algorithm to detect point of gaze (PoG) from both eyes.Developing a simple calibration method to increase accuracy.Developing a Graphical User Interface (GUI) to show results and conclusions.
