Project Description Gaze-Tracking used as a teaching tool
for photography Allows for the greatest level of mobility Design a portable gaze-tracker that
used two cameras simultaneouslyOne facing the userOne facing the area of interest

Design Summary
Mount Design Summary Mount Design
Used ABS Plastic for CasingUsed Aluminum for mountUsed GoPro parts for clip
PCB Design Summary Designed with PCB Express Two Boards used with 3 LEDs each Powered off USB 1.1”x 1.6” each
IR Testing
Focus Testing
Camera Testing
Accuracy Test
Usability Testing o 15 SUBJECTS RUN FOUR RANDOMIZED CALIBRATION
ROUTINE o THE SUBJECT FOLLOW A SINGLE DOT TO FIVE DIFFERENT
LOCATIONS ON THE SCREENo TWO DIFFERENT CALIBRATION VARIABLES - FAST OR
SLOW AND WITH OR WITHOUT DIRECTION o FAST WITH DIRECTION WAS DETERMINED TO BE THE
MOST ACCURATE ROUTINE
Current State of Project Hardware completed
Camera filter removed and reassembled
IR LEDs and PCBs integrated Case and Mount
manufactured and assembled Software completed
User Interface Calibration Debug Image Gaze Tracking (with poor accuracy)
Software in Progress• Gaze Tracking Reliability
• Pupil Detection • Eye Region Detection
• Overall Program Reliability
Conclusions/ Results Many Customer needs were met, but
gaze tracking should be more robust We learned a lot
Gaze tracking is a very tough problem, especially on a tablet
Learned importance of communication
Suggestions for Future Work Further work on making our system
more accurate and dynamic Screen to adjust algorithm parameters
Open source, portable library for gaze tracking
Use more Computer Engineers for future iterations
