▲ Securing computational design data through 4D scanner

Developing wearables with the optimal fit and comfort remains a difficult yet crucial challenge. Not only do these factors make the device feel more seamless to use, but they are directly tied to maximizing overall performance and sensor accuracy. However, the fact that each person’s anatomy is completely unique presents a major hurdle. But what if there was a way to meticulously engineer comfort, fit and sensing so precisely, it could deliver the optimal experience for nearly everyone?

Samsung’s solution is Computational Design. This multidimensional process harnesses AI and advanced computing to analyze hundreds of thousands of quantitative and qualitative data points to generate, test and refine product designs with greater precision. The result is a fundamental shift from subjective feedback to objective, data-driven engineering, creating superior products with the optimal fit for the widest range of users.

That description captures computational design in the abstract — like a dictionary definition. To understand how computational design is actually used to create superior wearables, Samsung Newsroom visited the Samsung Design Innovation Center (SDIC) in San Francisco, home to the Computational Design Lab.

▲ Federico Casalegno, EVP and Head of the Samsung Design Innovation Center

Spearheading the SDIC is Federico Casalegno, Executive Vice President and Head of the Samsung Design Innovation Center, who has spent the past two decades mastering the practice of computational design and leading the implementation of this core concept into Samsung’s product development. We sat down with Federico to discuss how SDIC employs computational design as a primary tool to create and optimize experiences for Samsung’s wearables, particularly the Galaxy Buds4 series.

Q. Tell us about SDIC’s role.

At SDIC, our mission is to deliver meaningful experiences by understanding people and their evolving lifestyles — always in the context of human-centered design. Ultimately, we want to delight customers and create products that help people live happier, healthier, more creative and more productive lives, while building a better future for all and preserving the environment. To achieve this, SDIC brings together the power of design and creativity with data-driven decision-making. Supported by AI, machine learning, robotics and advanced computing, our talented, multidisciplinary team of designers is constantly pushing the boundaries of what’s possible, delivering unparalleled user experiences and real, tangible benefits.

▲ At SDIC, design is combined with AI, data and computing to achieve maximum comfort for wearable devices.

Q. What exactly is computational design and what is the philosophy behind it?

While we live in a unique era of technological innovation, Samsung’s approach to design was always deeply human-centered as we believe that technology without humanity is merely perfection without purpose. Computational design is how we bring this philosophy to life — it is the process of harnessing the immense power of AI, data and computing to design products for people, rather than expecting people to adapt to our products. This approach helps us to create devices that are fundamentally functional, intuitive, comfortable and beautifully crafted. Today, this methodology is applied all across our wearable portfolio, including Galaxy Watch8 series and Galaxy Buds4 series.

▲ The computational design process involves various state-of-the-art testing equipment, including 4D scanning.

Q. How does computational design turn the ‘fit’ of a device into an objective, measurable metric?

For developing something as personal as a wearable that remains in contact with you for extended periods, fit is an essential element. It’s not just about comfort though; a secure fit is also needed for maximizing the precision of the device’s sensors. However, traditional design methods fail to measure wearability objectively, as they only rely on a small sample of people for product testing.

Computational design fundamentally changes this. By leveraging massive, digitalized datasets and advanced AI simulations, it transforms wearability into a quantifiable metric that allows Samsung to measure comfort and fit like never before. By being able to consider all the unique shapes and curves of the human ear or the wrist through computational design, our designers are equipped with trustworthy, objective insights that are difficult to attain through traditional methods.

▲ Optimal design parameters are derived through AI and physics-based simulations, which are then cross-verified with robot testing.

Q. Tell us in detail how the computational design process works in the lab and how it was implemented in the Galaxy Buds4 series.

Our computational design process relies on three elements: real people, digital twins and robots. We capture 3D and 4D scans of a diverse global audience, integrating precise anatomical data to create ‘digital twins.’ We then run AI and physics-based simulations, cross-validating the results with physical robot testing.

For the Galaxy Buds4 series, we applied this exact process to achieve perfect wearing comfort and premium sound. We analyzed hundreds of millions of global ear data points and ran more than 10,000 simulations to perfect the new blade design. This objective data led us to subtly reduce the size of the main head ¹ and refine the angle of rotation — minor adjustments that resulted in a dramatic, universally validated increase in stability and comfort.

Q. How does Samsung’s computational design ultimately benefit the users?

Samsung’s computational design process is powered by a unique proprietary dataset built exclusively from within Samsung and our team has developed several specialized AI programs based on this data. This combination gives us unique insights while we constantly innovate our design processes and methods. For Galaxy Buds and Watch specifically, this translates into improved wearing comfort, stability and sensor accuracy — key factors that elevate both the user experience and product performance.

▲ Samsung’s lineup of wearables, such as Galaxy Buds4 series, Galaxy Watch8 series and Galaxy Ring, all incorporate computational design in its development process.

Q. Looking ahead, how do you see Computational Design evolving over the next decade?

Computational design is now a foundational element of Samsung’s development process across all our wearable products. Our goal remains to maximize wearability, fit, comfort and sensor performance to ultimately serve the people using it.

Looking ahead, the true power of this process is its continuous evolution. As our dataset continues to grow, custom AI tools will drive more accurate simulations and deeper insights. These advancements will not only further improve product wearability, but also unlock exponential innovations down the line that lead to an entirely new category of wearables that can redefine the boundaries of user experience. Ultimately, this symbiotic partnership between computational design and AI frees our designers to be more creative, empowering us to deliver measurably superior products and experiences for the people who use them.

What’s New:

• New features¹  include Bedtime Guidance², to optimize your sleep; Vascular Load³, which measures stress on your vascular system while sleeping; Running Coach⁴, to help strategize your training; and Antioxidant Index⁵, to measure your carotenoids for healthy aging.
• The new features are part of One UI 8 Watch, which will be available on the newest Galaxy Watch series. Starting from this month, the features can be experienced through a beta program⁶ to a limited number of Galaxy Watch users.

Why it Matters: 

The goal of these new features is to help you build healthier daily habits, which can be challenging because they don’t develop instantly. It takes time to accumulate these behavior patterns, and meaningful changes are often only apparent after a long period. But the rewards are worth it.

• For example, eating unhealthy food may not immediately impact your health, but over time, it can have significant consequences.
• Conversely, adopting healthy habits may not show immediate results, but over time, they lead to positive changes in your body and mind.
• Samsung Health’s new features aim to help you develop healthy habits by motivating you through instant feedback on your health. These features inspire you to maintain your habits by providing rewards or warning signs and demonstrating immediate impact of your behaviors.

“Sleep remains a cornerstone of our approach to health, as it influences physical and mental well-being, social relationships and even work performance,” said Dr. Hon Pak, Senior Vice President and Head of Digital Health Team, Mobile eXperience, Samsung Electronics. “Now, we envision our Galaxy Watch delivering holistic insights centered around sleep — insights that lead to meaningful changes in daily life. We believe this aligns with our vision of empowering you to lead healthier lives through proactive care and holistic health management.”

Explore New Health Features

Samsung Health’s new features aim to help users develop healthy habits, using instant health feedback as a motivating tool.

A single night of restful sleep offers immediate health benefits, encouraging more proactive behavior changes and leading to a healthier tomorrow. This starts with a regular and optimal bedtime.

• We constantly seek to advance our sleep-related tools, which include sleep pattern analysis, sleep coaching, and optimizing sleep environments. They also include the feature that detects signs of sleep apnea⁷— a sleep disorder — and help you take proactive steps.
• Now, we are providing additional tools for better sleep by suggesting an optimal bedtime based on your lifestyle and sleep patterns while sending reminders to help you stick to it.
• By analyzing your past three days’ sleep patterns, the feature evaluates your need for sleep pressure and your circadian rhythm to calculate a bedtime that maximizes alertness the next day.
• This feature is particularly helpful for those trying to optimize their sleep after periods of irregular bedtimes. For example, if you go to bed later than planned over several days, or have inconsistent sleep schedules between weekdays and weekends, the bedtime guidance will consider these factors to ensure you get enough sleep.

Sleep is a window into overall health, as it impacts holistic well-being. Galaxy Watch uses this opportunity to measure vascular load — the amount of stress on your vascular system while sleeping.

• The vascular system carries blood throughout the body to deliver oxygen and nutrients and remove waste, making it a strong indicator to determine good heart health.
• During sleep, stress on your vascular system should naturally dip; however, excessive fluctuations can negatively impact cardiovascular health.
• Simply wear your Watch while sleeping, and it will measure your vascular load, providing insights into the stress on your vascular system.
• Additionally, since all health factors are interconnected, the feature also provides insights into lifestyle factors such as sleep, exercise, and stress to help you maintain a healthier lifestyle and develop positive habits.

While sleep is a precious time to cultivate and care for your health, managing your health during active moments is equally important. Running is one of the most basic and universally available fitness activities, and Samsung has long sought to support runners, offering features to help everyone stay active and achieve their fitness goals.

• Many runners face injuries due to over-pacing or are not optimally pushing themselves. Running Coach is designed to help runners safely complete marathons through optimized-intensity and injury-preventive training, making it ideal for beginners.
• Our new Running Coach feature delivers motivation and real-time guidance, creating a unique training program based on your fitness level to help you achieve your goals.
• Just wear your watch and run for 12 minutes; it will analyze your performance and running level from 1-10. You’ll receive a detailed training plan to help you complete a 5K, 10K, half marathon, or full marathon based on your level. Complete your training session, and you’ll level up and unlock your next running challenge.

When taking a holistic approach to health, we naturally focus on aging and inspiring healthy aging. However, behavioral factors, such as drinking alcohol, smoking, UV exposure, stress and lack of sleep, can accelerate aging by increasing free radicals in the body. These free radicals damage cells and accelerate aging. Antioxidants, nutrients found in many healthy foods, are molecules that neutralize these free radicals, helping prevent chronic illnesses and promote healthy aging.

• Use Galaxy Watch to measure carotenoids, which are antioxidants found in green and orange vegetables and fruits, stored in your skin.
• Galaxy Watch employs an industry-first feature to measure carotenoids in just five seconds via its advanced, light-activated BioActive sensor.
• These insights reflect behavioral changes. For example, drinking carrot juice can show changes in the index, providing motivation to adopt healthier habits.

Great health comes from the combination of many small changes — and with Galaxy Watch, it is now possible overnight.
