CVMD — Cognitive Variability Measurement Device

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.
