Rumble Rims Review: Can This Affordable Concussion-Detection Headset Make Youth Sports Safer?

Rumble Rims is an innovative sports-safety technology designed to address one of the biggest challenges in youth athletics: identifying possible concussions quickly enough to prevent athletes from returning to play while potentially injured.

Developed by three Harvard University graduate students, Rumble Rims uses infrared cameras and eye-tracking technology to provide coaches with additional neurological information following a suspected head injury. Rather than relying exclusively on an athlete's description of symptoms or a coach's visual observations, the system measures how the athlete's eyes move while completing a short screening exercise.

The idea is particularly interesting because concussion assessment technology has traditionally been associated with hospitals, specialist medical facilities, and expensive testing equipment. Rumble Rims aims to bring some of those capabilities closer to the playing field, making them more accessible to schools, youth sports organizations, and community athletic programs.

The project received international recognition after winning the Global Medical category of the 2026 James Dyson Award.

But is Rumble Rims ready to become an essential piece of sports equipment? How does its technology work, what makes it different from traditional concussion assessments, and what limitations should potential users understand?

Here is a comprehensive review of the technology, its features, potential benefits, pricing ambitions, and development prospects.

Rumble Rims: Product Overview

Rumble Rims is a sideline concussion-screening system built around a wearable headset, a coach-facing mobile display, and a recovery-tracking dashboard.

Its primary purpose is to help identify signs of possible neurological disruption after an athlete experiences a collision or head impact.

The system focuses on eye movements because certain neurological injuries can affect the way the eyes track moving objects, maintain fixation, and coordinate their movements.

Unlike conventional sideline assessments that may depend heavily on subjective observations, Rumble Rims aims to collect measurable information that coaches and medical professionals can use when deciding what should happen next.

The project was created by Radhika Saran, Sophia DeVito, and Cleo Pontone, who wanted to make objective concussion-screening technology more accessible to youth sports programs.

It is important to understand that Rumble Rims is currently a prototype, not a fully commercialized or clinically validated concussion diagnostic product. Its developers are still working toward further testing and real-world deployment.

How Does Rumble Rims Work?

The most interesting aspect of Rumble Rims is its use of infrared eye-tracking technology.

The headset is designed to observe an athlete's eye movements while the athlete follows a visual target displayed on a separate screen.

Here is how the process works.

1. The athlete wears the headset

When a player experiences a collision or suspected head injury, a coach or athletic trainer can remove the athlete from the game and initiate a screening session.

The athlete wears the Rumble Rims headset, which contains two infrared cameras positioned on either side.

The headset is designed to maintain a consistent relationship between the cameras and the athlete's eyes, helping reduce problems associated with relative head movement during testing.

2. Infrared cameras monitor eye movements

The headset uses infrared illumination and optical mirrors to capture eye movement patterns.

Its hot mirrors, positioned at approximately 45-degree angles, reflect infrared light toward the cameras while allowing visible light to pass through.

This arrangement is important because it allows the cameras to observe the eyes without completely obstructing the athlete's view.

During the test, the athlete follows a moving target on a smartphone or tablet positioned approximately an arm's length away.

3. The software evaluates neurological indicators

The system examines several aspects of eye movement, including:

• Smooth pursuit: How effectively the eyes follow a moving object.
• Fixation: How well the athlete maintains focus on a stationary target.
• Eye movement speed: How quickly the eyes respond to visual instructions.
• Tracking stability: Whether the eyes follow the target consistently.
• Oculomotor coordination: How effectively the eyes coordinate their movements.

These measurements may reveal abnormalities associated with neurological disruption.

The software then translates the collected information into a format that is easier for coaches to understand.

4. Coaches receive screening information

Once testing is completed, the system presents the results through a separate mobile interface.

The developers have described a dashboard that combines individual measurements into an overall risk indication.

The reported concept includes green, yellow, and red risk levels, helping communicate whether further medical evaluation may be necessary.

However, these indicators should not be interpreted as a medical diagnosis or automatic clearance to resume sporting activities.

5. Recovery can be monitored over time

Another interesting feature is the recovery dashboard.

Rather than limiting the technology to the moment immediately following an injury, Rumble Rims is designed to support repeated assessments.

This could allow athletes, families, coaches, and healthcare professionals to review changes in eye-tracking measurements throughout recovery.

Such information may be useful when considered alongside professional medical assessments and other clinical findings.

Key Features That Make Rumble Rims Interesting

1. Affordable concussion-screening technology

Affordability is arguably one of Rumble Rims' biggest selling points.

The developers say they built the current prototype for less than $350. This is significantly less expensive than some sophisticated clinical eye-tracking systems, which can cost tens of thousands of dollars.

According to the team's interview with the James Dyson Award, comparable specialist equipment can cost approximately $25,000 or more, while the team's broader project materials have referenced systems costing around $53,000.

For schools with limited sports-medicine budgets, a lower-cost screening system could make a meaningful difference.

However, the under-$350 figure represents the prototype's development cost, not a confirmed retail price. Manufacturing, software, maintenance, support, certification, and distribution could increase the eventual purchase price.

2. Quick sideline assessments

Speed matters when an athlete sustains a possible head injury.

Traditional concussion assessments can involve symptom questions, balance exercises, memory checks, and neurological examinations. These procedures may require trained personnel and additional time.

Rumble Rims aims to simplify one part of this process by providing a short eye-tracking assessment.

The developers describe testing sessions lasting approximately two to three minutes, while some early descriptions of the project refer to a test taking around 60 seconds.

Either way, the intention is to provide additional information without requiring athletes to travel to a specialist facility simply to undergo an initial screening.

A quick test could be particularly useful during school competitions, youth football matches, rugby games, and other sporting events where medical resources may be limited.

3. Objective information instead of guesswork

One of the most important problems Rumble Rims attempts to address is the subjective nature of some sideline concussion checks.

For example, a coach might ask an injured player to follow a finger with their eyes. Although this can provide useful observations, the results may depend on the examiner's judgment and the athlete's cooperation.

Athletes may also underreport symptoms because they want to remain in the game.

Rumble Rims attempts to introduce measurable eye-tracking information into this process.

Instead of depending exclusively on whether a player says they feel fine, the technology could provide another source of evidence that something might be wrong.

This does not make the device infallible, but it could help reduce reliance on guesswork.

4. Recovery monitoring

Many concussion-related technologies concentrate on identifying a possible injury. Rumble Rims also proposes a way to monitor athletes after the initial incident.

Its recovery dashboard is designed to store repeated assessment results and make it easier to observe changes over time.

This could be valuable when an athlete is recovering from a concussion because recovery is not always a straightforward process.

For instance, an athlete might report feeling better while certain neurological symptoms remain.

Repeated eye-tracking assessments could provide additional information for healthcare professionals evaluating recovery.

However, improvement in an eye-tracking score alone should never be treated as proof that an athlete has recovered completely.

5. Designed for schools and community sports

The product's intended audience is another important consideration.

Many advanced medical technologies are expensive and require specialist operators. This makes them difficult to deploy across schools and smaller sporting organizations.

Rumble Rims takes a different approach by designing the equipment around the sideline environment.

Its headset, mobile display, and recovery dashboard are intended to work together as a relatively portable system.

If the developers successfully complete testing and commercialization, the technology could potentially serve:

• High school football programs.
• College sports departments.
• Youth soccer academies.
• Rugby clubs.
• Community athletic organizations.
• Sports medicine departments.
• School athletic trainers.

Its affordability-focused design could make it especially attractive to organizations that cannot justify purchasing expensive clinical equipment.

Performance and Practical Usability

The concept behind Rumble Rims is promising, but its real-world performance will ultimately determine whether it becomes a valuable sports-safety product.

There are several important areas worth examining.

Eye-tracking accuracy

The technology depends on capturing eye movements accurately enough to identify patterns associated with possible neurological disruption.

The use of two infrared cameras and specially positioned optical mirrors is a thoughtful engineering approach.

However, a working prototype does not automatically demonstrate clinical accuracy.

The developers still need to establish how consistently the device performs across different athletes, age groups, lighting conditions, and testing environments.

It will also be important to determine how frequently the system produces false-positive or false-negative results.

A false positive could unnecessarily alarm an athlete or coach, while a false negative could create a dangerous sense of reassurance.

Ease of operation

Rumble Rims is designed to simplify sideline screening.

The athlete wears the headset, follows a target on a screen, and receives a result through the coach-facing interface.

This workflow appears more practical than transporting expensive specialist equipment to every sporting event.

Nevertheless, its usability needs to be assessed under actual match conditions.

Coaches may have to operate the equipment in noisy environments, under pressure, and with athletes who are distressed or uncomfortable.

The developers will need to ensure that the headset can be fitted quickly and that the instructions are easy to understand.

Comfort and fit

Because the headset is worn directly on the athlete's head, comfort is an important consideration.

The device must accommodate different head sizes without shifting excessively during testing.

It should also be comfortable enough for athletes who have just experienced a collision.

The development team has identified comfort and hardware refinement as areas for further work.

Software and reporting

The mobile interface is potentially just as important as the physical headset.

Coaches do not necessarily need complicated neurological measurements presented as raw technical data.

They need understandable information that helps them recognize when an athlete should be removed from play and referred for medical assessment.

The proposed risk-level presentation could make the software accessible to non-specialists.

However, the interface must avoid presenting a screening result as a definitive medical decision.

Rumble Rims vs. Traditional Concussion Screening

How does Rumble Rims compare with the methods currently used to assess athletes after a suspected concussion?

Assessment method	Main approach	Key limitation
Traditional sideline observation	Symptoms and visible behavior	Can be subjective
Follow-the-finger test	Visual tracking	Limited information on its own
Clinical concussion assessment	Medical history, symptoms, neurological examination and other tests	Requires appropriate clinical expertise
Rumble Rims	Infrared eye-tracking measurements	Still requires clinical validation

The main advantage of Rumble Rims is its attempt to introduce objective eye-movement measurements into the initial sideline assessment.

However, it would be misleading to suggest that it replaces a complete clinical concussion assessment. It is better understood as a proposed additional screening tool.

What about customer reviews?

At the time of writing, I could not establish a meaningful collection of independent customer reviews, verified purchases, or long-term user experiences. This is understandable because Rumble Rims remains a development-stage prototype.

Consequently, its current reputation is based primarily on design recognition, media coverage, and the developers' descriptions rather than established consumer feedback.

Pricing and Availability: How Much Does Rumble Rims Cost?

Affordability is central to the Rumble Rims project.

According to the developers, the current prototype was built for less than $350. This is an ambitious target considering that some specialist eye-tracking concussion assessment systems can cost approximately $25,000 or more.

However, there is an important distinction between prototype development costs and the eventual retail price.

A commercial product would need to account for:

• Manufacturing and assembly.
• Software development and updates.
• Hardware replacement and maintenance.
• Customer support.
• Medical-device regulatory requirements.
• Clinical validation and testing.

The development team is currently working toward a more advanced prototype, further accuracy testing, and potential pilot programs with schools and youth sports organizations.

There is no confirmed consumer retail price or general purchasing availability at present.

Is Rumble Rims Safe and Reliable Enough for Return-to-Play Decisions?

This is perhaps the most important question surrounding the invention.

Concussions are serious injuries, and returning to sporting activities too early can expose athletes to further harm.

Rumble Rims is intended to help identify possible neurological abnormalities following an impact. However, it should not be used as a standalone method for deciding whether an athlete can safely resume playing.

A normal-looking eye-tracking result does not necessarily rule out a concussion.

Similarly, an athlete who reports no symptoms may still require medical evaluation.

The developers acknowledge that their invention is a screening tool rather than a diagnostic device. They also identify clinical validation as a major next step.

For now, suspected concussions should be handled through established medical assessment and return-to-sport procedures. Coaches should not allow an athlete with a suspected concussion to return to play simply because a screening device produces a reassuring result.

Who Should Consider Rumble Rims?

Once the product is sufficiently developed, validated, and commercially available, several organizations could benefit from evaluating it.

Potential user	Possible benefit
High schools	Additional information during suspected sports injuries
Youth football clubs	More structured sideline screening
Rugby organizations	Additional neurological screening information
Soccer academies	Support for head-injury assessment
College athletics	Potential integration into sports medicine programs
Athletic trainers	Additional information for medical referrals

For professional sports teams with established medical departments, Rumble Rims could potentially complement existing assessment procedures.

Its most interesting potential market, however, is grassroots and school-level sports, where access to specialist equipment and medical professionals may be limited.

Final Verdict: Is Rumble Rims Worth Watching?

Promising innovation

Rumble Rims is one of the more interesting emerging sports-safety inventions because it addresses a genuine problem with a relatively straightforward technological approach.

Its biggest strength is its attempt to make eye-tracking technology more accessible outside specialist medical facilities.

The combination of infrared cameras, a portable headset, a coach-facing display, and a recovery-monitoring dashboard gives the project considerable potential.

I particularly like the idea of collecting measurable eye-movement information instead of relying exclusively on an athlete's description of symptoms or a coach's observations. This could become valuable in environments where players may feel pressured to continue competing despite possible injuries.

Nevertheless, there are important reasons to remain cautious.

Rumble Rims has not yet established the clinical accuracy required for widespread medical use. Its prototype cost is encouraging, but the eventual commercial price remains unknown. More importantly, independent clinical studies must demonstrate how reliably it identifies concussion-related abnormalities.

My assessment: Rumble Rims deserves attention as a promising sports-health innovation, particularly for schools and youth athletic organizations. However, I would not recommend treating it as a replacement for professional concussion assessment or purchasing it as an established medical solution at this stage.

If its developers can demonstrate reliable performance through clinical testing, the technology could become a valuable addition to sports-safety programs.

For now, Rumble Rims is a promising invention with considerable potential rather than a finished consumer product.
