Samsung Electronics, together with the University of Michigan, today announced that the University of Michigan Human Performance & Sport Science Center (HPSSC) — renowned for its integrated and comprehensive sport, exercise, and human performance-related research and education — has validated the high accuracy of Samsung Galaxy Watch’s fitness tracking features.

HPSSC’s Michigan Performance Research Laboratory (MiPR) found a significant correlation between Galaxy Watch and the clinical and sport science reference devices’ measurement of heart rate, sweat loss, VO₂ max and body fat percentage measurements, validating the reliability of Galaxy Watch’s monitoring capabilities. This partnership demonstrates how the collaboration between the two organizations makes advanced and precise fitness solutions to more people.

The MiPR studies verified the accuracy of Galaxy Watch’s fitness tracking features by monitoring key metrics from elite runners, including:

• Heart rate: As the most commonly checked health metric during workouts, heart rate measures how hard the heart works during physical activity. Findings show an excellent 90% correlation with electrocardiogram equipment while running, the gold standard in heart rate measurement.
• Sweat loss: Sweat loss estimates the amount of fluid lost during physical activity and helps guide proper hydration after workouts. The study found a 95% correlation for Galaxy Watch in assessing sweat loss over varying distances ranging from 2.5 km to 20 km.
• VO₂ max: Understanding how much oxygen the body absorbs during a workout helps individuals assess their fitness levels and set optimal goals and limits. The study demonstrated an 82% correlation, indicating acceptable alignment between Galaxy Watch and clinical-grade diagnostic equipment.
• Body fat percentage: Measuring a person’s body fat percentage allows for a better understanding of physical health and fitness than tracking body weight alone. Galaxy Watch readings showed a 95% correlation with dual-energy X-ray absorptiometry (DEXA) results, the standard diagnostic test for body composition using low-dose X-rays.

“We’re proud to be recognized by the renowned Michigan Performance Research Laboratory — their skilled researchers and expertise in wearable technology give us confidence in the accuracy of the Galaxy Watch’s fitness tracking capabilities,” said Dr. Hon Pak, Senior Vice President and Head of Digital Health Team, Mobile eXperience Business at Samsung Electronics. “We are committed to delivering precise and insightful fitness tracking experiences through strategic partnerships and advanced research.”

“Our partnership with Samsung exemplifies the power of combining industry-leading expertise with pioneering independent research at the academic level,” said Co-PIs Adam Lepley, MiPR director and associate director of HPSSC research. “Together, we can advance scientific discovery and provide information back to consumers that will enhance the use of Samsung’s technology. This synergy underscores the power of uniting academic excellence with industrial innovation, and we are grateful for this collaboration.”

“We are excited to continue our partnership with Samsung to ensure that innovations in wearable technology are accessible and accurate across all segments of the population,” said Kenneth Kozloff, HPSSC co-director. “HPSSC and MiPR are eager to unveil these outstanding outcomes that solidify our commitment to enhancing heart rate and health monitoring and are look forward to future collaborations.”

The following tips can enhance your fitness journey with the Galaxy Watch series, from setting personal goals to post-workout recovery:

Q. When it came to product planning, what were your priorities and which features were focused on to optimize the Gear IconX’s usability and functions?

Park: This is the second generation of the Gear IconX, and as such we took the time to really listened to user feedback to help us improve upon our first design.

A significant priority was to ensure that the Gear IconX is the best companion to smartphones it can be. We wanted to make sure that a smartphone paired to a Gear IconX would be able to provide better and more features and functions than it can with wired headphones.

For example, the earbuds can store and play tracks without being connected to a smartphone. We also designed the Standalone Running Coach with voice guide, which tracks your workout, coaches you by providing real-time updates on exercise and is seamlessly integrated into the Samsung Health app. In addition, holding a button will trigger voice command and those who have Samsung smartphones are able to directly transfer their songs to their Gear IconX while connected to Bluetooth.

Battery life was another key consideration for cord-free earbuds with lots of features. The Gear IconX can achieve up to five hours of music streaming via Bluetooth and seven hours of stand-alone music play. But even if users do run out of battery, the Gear IconX’s charging case is able to recharge the earbuds, so they can keep on going wherever the user takes them throughout the day. There’s also a Quick Charge function to provide that extra boost when needed.

Q. Were there any difficulties in achieving the ideal balance between form and function?

Park: There definitely needs to be a careful balance between form and function. We wanted to fulfill all user needs and the most difficult hurdle was overcoming the basic limitation of size. We worked hard to figure out how to provide a long battery life, without taking away from the design and size, as well as finding the optimum balance among various features.

Choi: Not having a display was another challenge. The product had to be intuitive and easy to use so that users wouldn’t have any trouble using and adjusting the settings and functions. There were months of discussions and refinements involved.

Q. In terms of design, how important was overall comfort?

Park: Well, everyone’s ears are shaped differently, but the design had to suit as many people as possible and a lot of effort was put in to ensure this. We conducted a lot of studies and sought out the most ergonomic design. Our chief concerns were about angles, ear-comfort, stability and fixedness even during high impact movement, and of course size. Since the IconX can now be used for longer than ever, we wanted to ensure that users had complete comfort throughout.

Q. What are the advantages of using a touchpad? Can you elaborate further about the process of designing one?

Park: Pressing keys requires a degree of force, which is quite uncomfortable for users while they are wearing earbuds. A touchpad eliminates the need for keys and suits the Gear IconX’s minimalist design.

Inputting through keys had to be limited in order to deliver all the functions and features that we wanted to provide.

Choi: Our designers call it the invisible UX – there’s no screen and it can’t be seen. UI feature designers often got together to discuss basic interactions and how to ensure users would intuitively understand how to use the UX. It was important to know how much users can remember and internalize, and how quickly they could adapt to the newly applied touch and hold features.

An additional challenge was posed in optimizing the sensitivity of the touchpad.

When we say “swipe up”, everyone has a different idea of what “up” is. They go sideways, diagonal and straight up. We went through every possible scenario and gathered information through trial and error. We had to enlist the help of hundreds of internal staff in the trials.

Q. How was the sound quality of the Gear IconX achieved?

Park: The kernel design of the Gear IconX optimizes sound insulation and helps to block out any noises surrounding the user. Our greatest efforts were put into making sound output seamless. Since the earbuds are cord-free, and connected to a device via Bluetooth, sound must not be staggered or cut off. We wanted to minimize disturbances in the connection, particularly in underground spaces such as subway stations, where a cord-free product encounter lots of interference.

To achieve this, the Gear IconX’s sound output is stabilized with Samsung’s Scalable Codec, which continuously analyzes interference from WiFi and other Bluetooth signals and adjusts to minimize the impact on audio performance. The Scalable Codec decreases bit rate whenever the Gear IconX senses that the signal transfer is being disturbed, ensuring seamless music playback.

Q. When do users want to wear the Gear IconX the most?

Park: Gear IconX can be used whenever people want to listen comfortably and cordlessly – while they’re commuting or relaxing at home, for example.

Users can really focus on getting the most out of their exercise. The Gear IconX has many features which make it suitable for wearing while working out. Because the earbuds can store tracks and playlists, they can function independent of a smartphone, so users aren’t distracted by a screen. It’s sweat-resistant, ergonomically designed and features the Standalone Running Coach to help users maintain their pace. In addition, auto run/walk tracking give up-to-the-moment information about distance and speed. People often listen to music while exercising, and Gear IconX’s fitness features have been positively received by users.

Q. What has the consumer reaction to the Gear IconX been like?

Park: In the days since the launch, the early reactions from users have been pleasing to us as planners and designers, who worked hard to achieve them. Tech reviews have been shared widely, piquing the interest of the general public and consumers.

Tech-savvy users have also provided insightful commentary on how to use the Gear IconX. Since this Gear IconX is new to the market, their considerations are a useful resource for both consumers and Samsung.

Samsung Electronics today introduced three new devices to its industry-leading wearable portfolio: Gear Sport, a sleek and versatile fitness-focused smartwatch that is water resistant; Gear Fit2 Pro, an upgraded GPS sports band with smart features; and Gear IconX, a second generation of the company’s groundbreaking cord-free earbuds.
