Empower elders to walk more confidently.


In this class, we were tasked with designing a innovative wearable that incorporates existing AI technology as a personal assistant.

Jon's grandma loved the freedom of walking everywhere. After her knee surgery, however, she can no longer walk as easily, and relies on her family to drive her around.


Our team designed STRIDE, AI-powered insoles for elders that learn their walking paterns to help them walk more confidently. It comes with a companion wristband that alerts them when imbalance is detected.

As people age, their mobility can decrease, making walking more challenging.

  • 36,000,000 falls among elderly each year

  • 1 out of 5 falls caused an injury

  • $12 million every year spent out of the pocket to treat injuries caused by falls


AI smart insoles - Learn your walking patterns and help you stay balanced with every step.

AI sensors

Sensors collect gait, kinematics, balance, center of mass motion, ankle and hip angles, and sway velocity data to accurately gauge your walking capabilities.

Replaceable battery

Inspired by the Nike + iPod fitness device, we create magnetically rechargeable batteries that easily slip in and out of the insole

Inflatable bubbles

Through biometric sensors and algorithm analysis, STRIDE insoles can autonomously expand and contract the support bubbles

Interchangable batteries - Last up to 72 hours, and a portable USB-C charging case.

Smart wristband - tightens for a gentle nudge, reminding you to take breaks while walking.

Tactile nudge

Give users a mix of tightening and haptics to nudge them for resting when detecting signs of imbalance or fatigue.

Magnetic clasps

A magnetic clasp makes wearing bracelets easier, which is great for people with hand or mobility difficulties.

Customizable materials

Stride offers a variety of comfortable, sustainable materials for different occasions.

Find accessible routes.

Plan accessible trips and find routes with accessible features, all on the go.

Find directions with AR Compass

Lay out the real-world directions right in front, making it easier to start the route.

target audience

Focus on 65+ years old adults.

In 2022, there were 771 million people globally aged 65 and above. Given that 1 in 3 in this demographic struggles from foot pain, stiffness, or aching feet, we recognized an opportunity to help this substantial population segment.

  • Active lifestyle - They love to participate in fitness activities and still want to stay active.

  • Mobility challenges - They start to experience age-related decline in their walking ability.

  • Health - They prioritize health and be willing to invest in products that benefit their health.


  • Everyday errands - Picking up groceries, cleaning the house, doing laundry

  • Exercise - Going walks in the park, practicing taichi, doing yoga, jogging

  • Traveling - Walking around new cities, exploring the museums, doing food tours, going on hikes

user research

Interview with people.

  • 11 user interviews - Learn more about footwear preferences, their adoption of new technology, their perception of aging.

  • 2 concept reviews - Refine the concept with product designers in wearable (Garmin) and accessibility (Lenovo).

  • 2 Brand surveys - Understand psychology and perception to develop the brand strategy for our products.


Many older adults crave the freedom they once had at a younger age, where they weren't dependent on others to perform simple tasks.

Many older adults still try to appear independent while avoiding visible signs of aging (wearing medical aids, relying on others)

Many older adults feel motivated by sharing their achievements and progress with their loved ones while staying connected with them

Market research

What's missing in existing products.

Though there is a significant growing demand for our user group, the existing products in the market are not fully address the needs of our users. We analyzed from walking aids to smart wearables and home devices.


Some mobility aids and home systems can make users overly dependent, reducing their confidence to move independently.


Off-the-shelf solutions may not fit individual needs well, leading to discomfort and inefficiency.

Usability and Accessibility

Complex controls and small interfaces can make some devices hard to use, especially for elderly users.

Many product UIs are still inaccessible, leading to older adults' hesitance in adopting new tools.

Spatial challenge

Elders struggles to understand their surroundings and making cognitive decisions related to navigation and maps.

Cognitive challenge

Digital maps' interfaces can be complicated and overwhelming for our users to understand and navigate.

Lack of resources

Many apps provide wheelchair and ramp features; however, these resources are not particularly relevant/tailored to our users.


How might we design a wearable technology that provides older adults with support and confidence to walk independently, reducing their fear of falling?

How do we define confidence?

  • Independence - They can perform tasks without having to rely on someone else.

  • Safety - They feel safe and secure when performing tasks without fearing of injuries.

  • Comfort - They feel confident and comfortable wearing our products in many scenarios and occasions.

design goals

Define achievable goals for our design.


Reduce learning curves by utilizing familiarity, affordances, and accessibilities.


Simplify cognitive load, helping to focus on what’s important and make the decision easier.


Communicate our brand’s value proposition that resonates with people we design for.


Minimize users' reliance on their phones, enabling them to focus and enjoy on their walks.


Strive for a versatile design that blends in with everyday wear and fits in with different styles and occasions.


Reduce users' reliance on their phones (For trip planning only), letting them focus on their walks.

mobile app

Design the MVPs and test often.

user flow

aha moment

Designing for accessibility is more than just applying WCAG guidelines.

Different fonts display varying sizes, even at the same 24px setting. Or with colors, applying what I learned from my Color Theory course, the same purple will appear differently on different background color. Therefore, throughout the process, I had to adjust the font and color according to my judgement and continuously test with my team and peers.

Recognition rather than recall

We learn that people struggle to memorize street names so we wanted to change to navigation with landmarks to help them recognize familiar objects rather than recalling names.

Color theory comes in handy

Throughout the process, I had to adjust the font and color according to my judgement and continuously test with my team and peers.

Pivot to a new concept

After talking to many users, we learned that our v.1 concept wouldn't be able to compete with other strong smart watches competitors from Apple, Fitbit, or Garmin. We decided to pivot but at this point, we're running out of new ideas and time.

V.1 wristband concept (Usability testing)

Instead of using visual and audio cues, we changed the focus to tactile cues. We designed a wristband that can tighten to notify the user.

V.2 tactile wristband concept (Rapid protoyping)

To test the size and position of the wristband, we created tape prototypes. We then used Rhino to create 3D models of the final design.

V.2 concept - 3D printing and assembly

After many rounds of testing, we landed on the best version of the wristband. We then 3D printed the prototypes and assembled them.

V.2 concept (Usability testing)

We were surprised by the positive response to the concept and appearance of the wristband. The feedback we received was invaluable and helped us refine the final design.

Project plan

We iterate, test, improve, and repeat

Throughout the project, we applied the Lean Startup Methodology, where we tested our initial and rough designs, collected feedback from users, made pivots, and then iteratively improved our products.
