Background
- This research was conducted by Tommy Powers and Cameron Fleming in the Spring Semester and Fall Semester of 2012 at Washington University in Saint Louis. It was part of the Undergraduate Research Program in the Preston M. Green Department of Electrical and Systems Engineering. This project was overseen by Dr. Arye Nehorai, Ed Richter, and Phani Chavali.
Project Overview
- The goal of this pupil tracking project is to provide a method of communication using eye movement for people with Amyotrophic Lateral Sclerosis (ALS) who are unable to control voluntary muscle movement in their limbs. The project will be developed in two main phases:
- Develop an algorithm to track the movement of the pupils.
- Develop hardware in order to capture the movement of the eyes so that it may then be processed.
Our work focused on the first task in order to construct a robust pupil finding algorithm. We tried a variety of ways to track the pupils and in this report we focus on the most robust of these.
Eye Tracking Steps
- The eye tracking algorithm uses the following detailed steps:
- Eye Region Extraction
- Homomorphic Filtering
- Eye Tracking
- Kalman Filtering
