Harvard students build headset to screen for concussions in about 60 seconds

Three Harvard students have developed a low-cost infrared headset called Rumble Rims that can screen athletes for potential concussions in around 60 seconds. The invention, which came in first place at the 2026 US James Dyson Award, integrates a portable infrared headset, a coach-facing mobile display, and a recovery dashboard. Rumble Rims uses infrared cameras and hot mirrors to capture eye-tracking data during a short oculomotor task, providing real-time guidance to coaches on whether an athlete should be removed from play or referred for medical evaluation.

Though the device is not a diagnostic tool, it fills a gap in current sideline assessments that rely on subjective symptom checklists and balance tests. The students consulted with coaches, athletes, and medical professionals during design to ensure the headset's effectiveness in real-world situations. Recognized with a $6,500 prize, Rumble Rims aims to become a widely accessible tool for school and community sports programs, with further validation needed before broader adoption.
