I designed a computer vision-based toothbrush and feature tracker, including a trackable toothbrush prototype, while working at the Intelligent Assistive Technology and Systems Lab (IATSL) under the supervision of Dr. Alex Mihailidis. Our goal was to aid in toothbrushing tasks for elderly people and people with demetia using unobtrusive, webcam-based methods. In future, the system will infer a person's actions, providing guiding prompts if needed. This project is part of COACH, one of the first clinically tested supportive environments to use artificial intelligence techniques.
Infrared Toothbrush: Wrapping made out of infrared tape
Infrared Difference Tracking: I tried comparing difference images
Bi-Color Tracking: Then I switched to a color approach
Face and Feature Tracking: Then I tracked face, eyes and mouth
Final Toothbrush Prototype: Designed for Bi-Color Tracking
