Sameer

A low-cost Arduino device — ELEGOO UNO R3, Sanwa arcade buttons, LEDs — that measures cognitive performance in real time to test whether wearable readiness scores actually predict behavioural impairment. Wearables hand you a readiness number that nobody has validated against real cognitive performance; this builds that ground truth. Sameer pivoted from this hardware to a software version, then a coaching dashboard, before the pose-and-wearables tennis prototype he demoed at the end — which chases the same readiness-to-performance link.

A prototype to answer whether a bad performance comes from fatigue or technique. It pairs physiological data — readiness, sleep and HRV — with pose data extracted from his own match video using Google MediaPipe and custom Python, measuring signals such as peak racket-hand speed. The N-of-one findings showed a strong correlation between high readiness and higher swing speed, connecting physiological readiness with tennis technique in a way existing tools do not.
