2. Status Update Our Project consists of a head-mounted eye-set that provides automated ocular-based concussion testing and diagnosis for sideline use. o Project Status  In communication with several experts, planned meetings and phone calls to gather concussion-based research and contacts General idea endorsement by Dr. Vincent Miele, with suggested addition of integrated balance testing  Proposal submitted to NFL-UA-GE Head Health Challenge II o Parts Status  Prototype parts ordered on February 8th, most acquired this morning 2

5. Risks and Mitigation RisksMitigation Plan Direct access to concussed patients for testing might not be available Extensive testing with un-concussed subjects; UPMC contacts may help Eye-set design may be uncomfortable, unbalanced, or clunky Design a compact housing for RasPi and sensors, possibly with counter balance Camera focus may lack sharpness and clarity to perform eye analysis on a wide variety of eye types Alternative lenses may need to be acquired; image and video processing algorithms may account for possible blurs Plan APlan BPlan C Android App works smoothly; ergonomic eye-set performs accurate tests; individualized player diagnoses Individualized player diagnoses give way to more general tests; the eye-set and App are still well packaged and easy-to-use Less refined eye-set performs accurate, general tests that are reliably sent to an easy-to-use App interface 5
