Harvard Headset Wins Global Prize for Concussion Checks
Three Harvard University students have won the global medical prize in the 2026 James Dyson Award for a low-cost headset designed to screen athletes for possible concussions on the sideline.
Rumble Rims, created by Cleo Pontone, Radhika Saran and Sophia DeVito, uses infrared eye-tracking to look for signs of neurological impairment shortly after a possible head injury. The team will receive $40,000 to accelerate development of the technology, according to the James Dyson Award announcement.
The award, announced on 4 November, puts a student invention for everyday school sport at the centre of a global design competition. The competition drew 2,294 entries from 28 countries and regions this year, its highest total yet, according to coverage of the winners.
A gap on the sideline
Concussions are notoriously difficult to spot in the moment. Symptoms vary from person to person and can take up to 72 hours to appear, which means a player who looks fine immediately after a collision may still be injured.
At the same time, the objective tests that do exist are often expensive and clinic-based, putting them out of reach for most school and grassroots teams. Coaches and parents are therefore left to rely on subjective sideline checks, such as asking an athlete how they feel or watching for obvious signs of distress.
The Harvard team set out to close that gap. Their aim was not to replace a doctor, but to give the adults at the side of the pitch a more objective signal in the minutes when a decision about whether a player should continue has to be made.
That challenge matters well beyond elite sport, and it is familiar in college sport, where fixtures come thick and fast and medical cover varies. A figure cited in coverage of the earlier United States prize put sports-related concussions at 15.1 per cent of United States high school students, roughly 2.5 million young people, in a single year.
How Rumble Rims works
Rumble Rims combines a portable infrared headset, a coach-facing display and a recovery dashboard. Side-mounted infrared cameras, working with 45-degree dichroic mirrors, watch how an athlete’s eyes follow, fixate and move during a short test.
The athlete completes an eye-movement task in infrared light that they cannot see. A mobile display then turns those measurements into real-time guidance on whether the player should come off and see a doctor. A recovery dashboard logs repeat tests over the following days, helping adults track changes rather than relying on a single snapshot.
Coverage of the global win describes the test as lasting two to three minutes. Earlier material about the United States national prize had described a screening in about 60 seconds, a difference that appears to reflect how the test has been described at different stages of development rather than a change in its purpose.
The team is careful about what the device is not. Rumble Rims is intended as a screening tool, not a diagnostic device, and return-to-play decisions remain under the direction of a qualified healthcare professional. That distinction is central to the design: the headset flags possible impairment for medical assessment, it does not clear an athlete to return.
From a national prize to a global win
Rumble Rims first won the United States national prize in the James Dyson Award on 16 September, carrying a $6,500 award. It then advanced to the international shortlist before being selected by Sir James Dyson as the global medical winner.
The other global prize, for sustainability, went to Sentinel, a building-damage sensor by Aldrei Ong, a structural engineer and graduate of De La Salle University in the Philippines. Each global winner receives a prize worth £30,000, according to international coverage, equivalent to the $40,000 figure given in the United States release.
The inventors argue that medical innovation often reaches well-funded programmes first and ordinary schools later. A low-cost, portable system could reverse that order, bringing screening to a school field rather than only to a hospital. The same access question runs through debates about artificial intelligence in schools, where powerful tools are often adopted unevenly.
What happens next
The team says its next steps are a more refined prototype, testing with coaches and medical advisers, and eventually formal medical device validation. Pilots with schools are also planned, so the headset can be tested in the noisy, hurried conditions of a real match day rather than only in a laboratory.
Those steps matter because a screening tool must be reliable under pressure and honest about its limits, which is why the inventors stress medical supervision at every stage. If it succeeds, the most important result will be a quiet change on sidelines everywhere: a coach with better information, a player taken off sooner, and a medical assessment that happens before further harm.
Education Times reported that the team will use the $40,000 to accelerate development and testing of the technology.
