Video Oculography

2021 Senior Design


Video Oculography (VOG) Goggles are a form of ocular movement imaging and are used in a clinical test to diagnose disorders of the vestibular system. The current VOG system used by our customer, Dr. Mamikoglu, has shortcomings that we want to address with a new design. The current VOG system comes with many wires and cords that are cumbersome to set up and make it hard for a patient to move around freely during the medical exam. Our customer also wants a device that is accessible to non-ENT’s, ER staff and even at-home patients during telehealth appointments. Lastly, the current system has only one eye camera (as opposed to two) which limits the diagnostic applications and slows down the exam. This project primarily focuses on making a better version of the VOG system that solves the current problems our customer has.

Problem Statement

The primary goal of this project is to design a Video Oculography system (VOG) that is cordless to allow free movement of both patient and physician during a VOG exam. Furthermore, the system shall be user-friendly (both in the computer software and in the goggle system hardware), relatively inexpensive, and it shall contain two cameras as opposed to one.

Customer Feedback

Our customer has been very satisfied with our overall progress and sees many possible future applications for our device. He envisions our goggles to become a staple not only in an ENT’s office, but also in the ER, and even at home for telehealth applications.

Our customer has expressed particular appreciation for the wirelessness, the number of cameras on our device, and the possibilities for continuous improvement given our rather modular design.

What’s Next?

We want to make the setup of our device more user friendly and ideally improve upon the user interface on the software end to make it more accessible. We are considering adding other sensors and software to our existing prototype to improve the diagnostic power of the VOG Goggles.
