Rithmio aims to help your wearable device distinguish a bicep curl from a bench press

Wearables are in need of some revitalization, and a startup in Chicago may have just the thing: software that helps wearable devices quickly learn and discern specific motions. This has particularly compelling implications for people who wear fitness-tracking wristbands and smartwatches while working out.

Rithmio, a startup co-founded by a graduate student at the University of Illinois at Champaign-Urbana and his Ph.D. adviser, has developed a software platform that “integrates with motion-sensing devices such as wearables or smartphones to learn, track, and analyze gestures,” according to its website.

One of the applications is enabling wearable devices to more easily recognize a dynamic range of gestures and activities without having copious movement data. Currently, people who wear fitness bands and smartwatches are often hamstrung by those devices’ ability to track only a limited number of simple movements, like running, cycling, and climbing stairs.

Rithmio hopes to kick the door open to a wider range of fitness-tracking possibilities. The startup says its software can learn new activities (e.g., squats, bicep curls, bench presses, jumping jacks) in a matter of seconds and measure speed and repetition, for instance. The algorithm can also distinguish between subtle differences, such as small and medium-sized arm rotations. The next step for the software is determining your form and efficiency compared to previous workouts, according to Adam Tilton, Rithmio’s CEO and co-founder.

While the company’s apps haven’t been released yet, the company plans to share software tools later this year to let developers use its gesture-recognition know-how on Android Wear smartwatches, the Apple Watch, and the iPhone, according to MIT Technology Review. Tilton says Rithmio is working with the likes of Intel to embed its technology into chips and devices. He adds that Rithmio will be built into products sometime next year.

Wearable devices that can track and analyze a wider range of movements and activities could revive a flagging industry. About a third of fitness-tracking devices are abandoned after six months, according to research firm Endeavor Partners.

“A health care investment fund, Rock Health, says Fitbit’s regulatory filings suggest that only half of Fitbit’s nearly 20 million registered users were still active as of the first quarter of 2015,” according to the Associated Press.

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

Garmin watches are known for their robust activity tracking, but that's not all these fitness watches can do. Over the years, the company has been adding wellness features to its lineup of watches. These new health-focused metrics allow people to analyze their fitness and identify outside factors affecting their performance. One such factor is stress, which is something Garmin watches actively measures.
But you may be wondering—exactly how does Garmin measure stress? In this article, we break down how Garmin measures stress and delve into the accuracy of this metric. Should you trust your stress score? Read on to find out.

Is Garmin's stress score accurate?
