Inspiration
Falls at night are one of the biggest risks for older adults and people with health challenges. We wanted to create something simple, familiar, and comfortable that could provide peace of mind by making every step at night safer.
What it does
SafeStep is a smart slipper that helps elderly people and those with mobility issues avoid obstacles in the dark. Using an ultrasonic sensor, it detects objects and buzzes more frequently as the wearer approaches them, almost like echolocation. It looks and feels like a normal slipper, complete with a cute bunny design, and includes an on/off button so it can function as a regular slipper during the day.
How we built it
We wired an ultrasonic sensor and active buzzer to an Arduino Uno using a breadboard, programmed the logic, and embedded the system into a cozy slipper prototype. We added an on/off button for ease of use and decorated it with a playful bunny theme to make the design approachable.
Challenges we ran into
-Learning Arduino and breadboarding from scratch. -Debugging sensor readings and wiring errors. -Making the slipper comfortable while still housing electronics. -Time pressure causing us to abandon 3d print design
Accomplishments that we're proud of
-Creating a working prototype in just two days. -Designing for elderly users with both safety and comfort in mind. -Building something that’s practical, approachable, and a little bit fun.
What we learned
We learned how to wire and code Arduino hardware, and more importantly, how to think about health and wellness design for vulnerable populations. We discovered that the best solutions often come from turning everyday objects into smart, protective tools.
What's next for SafeStep
We’d love to 3D print the slipper in TPU for a more ergonomic, durable design. Looking forward, we imagine expanding into other animal-themed styles and exploring new sensors to make nighttime navigation even safer for seniors.
