3. 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 simultaneously One facing the user One facing the area of interest

4. Customer Needs

5. Project Specifications

6. Final Design

7. Bill Of Material

8. Design Summary

9. Mount Design Summary  Mount Design Used ABS Plastic for Casing Used Aluminum for mount Used GoPro parts for clip

10. PCB Design Summary  Designed with PCB Express  Two Boards used with 3 LEDs each  Powered off USB  1.1”x 1.6” each

11. IR Testing

12. Focus Testing

13. Camera Testing

14. Accuracy Test

15. Usability Testing o 15 SUBJECTS RUN FOUR RANDOMIZED CALIBRATION ROUTINE o THE SUBJECT FOLLOW A SINGLE DOT TO FIVE DIFFERENT LOCATIONS ON THE SCREEN o TWO DIFFERENT CALIBRATION VARIABLES - FAST OR SLOW AND WITH OR WITHOUT DIRECTION o FAST WITH DIRECTION WAS DETERMINED TO BE THE MOST ACCURATE ROUTINE

16. 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

17. 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

18. 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
