MotionSync

model and code

Motivation

The goal of improving fitness tracking's accessibility, sustainability, and interactivity motivated us. Although there are various step counts, the majority use traditional algorithms and plastic casings. Our goal was to create something gamified, eco-friendly, and do-it-yourself that would make training entertaining, interesting, and sustainable. As a result, MotionSync—a wearable step tracker that incorporates play into regular exercise in addition to counting steps—was created.

What it does

MotionSync is a wearable step-tracking gadget that uses an MPU6050 accelerometer to detect motion, an Arduino to compute data, and Bluetooth to provide step counts (HC-05). MotionSync is lightweight and environmentally friendly because it is enclosed in a wooden case, unlike conventional step counters. MotionSync precisely records movement with each stride, allowing users to play step-based games, track their fitness progress, and incorporate movement into interactive experiences.

How it was constructed

The MPU6050 was our first choice for a motion detection sensor, and we connected it to an Arduino Nano/Uno for data processing. The HC-05 Bluetooth module enables smooth wireless transfer to a gaming system or mobile application. We created a wearable hardwood housing with laser-cut joints for a natural, biodegradable structure in order to guarantee sustainability. By establishing an acceleration threshold and increasing a counter each time a legitimate step motion was identified, the step detection method was put into practice.

Challenges we ran into

One of the biggest challenges was filtering out false steps caused by random hand movements. We had to fine-tune the threshold and introduce noise filtering techniques to ensure accurate step counting. Additionally, integrating Bluetooth connectivity required debugging communication delays. Finally, designing a comfortable, durable, and sustainable wooden wearable presented an engineering challenge, as we had to ensure the structure remained lightweight yet sturdy.

Accomplishments that we're proud of

We’re proud of creating a fully functional, low-power, and sustainable wearable that successfully tracks steps without requiring plastic components. The Bluetooth integration enables real-time data tracking, making the device more interactive. Most importantly, we successfully turned a basic step tracker into a fun, gamified experience, making movement feel like a rewarding adventure rather than a chore.

What we learned

Through this project, we gained a deeper understanding of sensor data filtering, low-power wearable design, and Bluetooth communication protocols. We also learned how to balance sustainability with functionality, proving that eco-friendly materials can be used for high-tech applications.

What's next for MotionSync

Next, we want to integrate machine learning to make step detection even smarter, filtering out false positives dynamically. We also plan to develop a mobile app with real-time tracking, fitness challenges, and social leaderboards. Additionally, we’re exploring ways to use kinetic energy harvesting to make MotionSync a self-powered device, further enhancing its green technology potential.
