Introduction<\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Problem Statement<\/h2>\n\n\n\n

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.<\/p>\n\n\n\n
