Rapid Ocular Sideline Concussion testing System

This project involves a head-mounted eye-set for automated ocular-based concussion testing on the sideline. Parts are ordered, and prototype assembly is in progress. The design includes an Android tablet, TFT display, camera, RasPi with OpenCV, and WiFi module. The diagnosis process involves administering tests via TFT display, recording eye movements, and analyzing data on a tablet interface. The system is activated by a trainer via an app interface, with tests such as Dilation Test, Depth Test, and Tracking Test conducted.
