[Code Project]TrackEye : Real-Time Tracking Of Human Eyes Using a Webcam

Introduction

Eyes are the most important features of the human face. So effective usage of eye movements as a communication technique in user-to-computer interfaces can find place in various application areas.

Eye tracking and the information provided by the eye features have the potential to become an interesting way of communicating with a computer in a human-computer interaction (HCI) system. So with this motivation, designing a real-time eye feature tracking software is the aim of this project.

The purpose of the project is to implement a real-time eye-feature tracker with the following capabilities:

• RealTime face tracking with scale and rotation invariance
• Tracking the eye areas individually
• Tracking eye features
• Eye gaze direction finding
• Remote controlling using eye movements
