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 possible concussions in about 60 seconds. The device, named the 2026 US winner of the James Dyson Award, utilizes infrared cameras and hot mirrors to capture eye-tracking data during a short oculomotor task. The data is then translated into simple, real-time guidance for coaches to make faster and clearer decisions about whether an athlete should be removed from play and referred for medical evaluation.

Rumble Rims aims to bridge the gap between current sideline assessments, which often rely on subjective judgment, and more expensive clinical eye-tracking systems that are not designed for quick use on a busy field or in a school gym.
