Totomi

Inspiration

We wanted to create something that reacts to your environment and helps you to take positive action. When we were brainstorming, we all got really excited about the idea of super-powered Tamagotchi. After a couple of rounds of iterations and speaking to mentors we realised that this can be not only fun but also very purposeful.

What it does

Totomi is a physical-virtual companion, like a "well-being twin," that reflects your environment and habits.

If you’re in a polluted area, it feels bad; if you’re active and in a healthy space, it thrives.

By caring for it, you’re encouraged to make better choices, turning self-care into an interactive, emotional experience.

How we built it

We began by selecting sensors that could provide meaningful insights in real-world contexts. An Inertial Measurement Unit (IMU) captured daily movement data, while air quality and temperature sensors provided comprehensive environmental monitoring.

The data transmission utilized a 3D-printed, battery-powered mascot equipped with an ESP32 microcontroller, which integrated with Unity through the Singularity package. We leveraged the MRUK SDK alongside Meta's XR development tools, including Hand Tracking and Audio SDKs. VFX Graphs enabled sophisticated spatial simulations of smog and weather phenomena.

All 3D assets were created using Blender, involving custom modeling, rigging, and animation to ensure a highly personalized and immersive experience.

Challenges we ran into

Establishing the connection between the ESP32 and the headset proved more challenging than anticipated, requiring significant debugging efforts to successfully integrate the two systems.

Accomplishments that we're proud of

The narrative and technical implementation of the project converged successfully, enabling us to prototype an innovative XR experience that effectively bridged the digital and physical representations of Totomi.

What we learned

We learned that coming up with a tangible prototype comes with it's problems but being able to iterate through design can help improve the process drastically. We were pleasantly surprise by how each member was able to take on specific roles and still work in harmony. And having our own 3D printer was truly a blessing

What's next for Totomi

Totomi should continue to thrive, having a chargeable version is the next key step, in order to not worry about changing the batteries every once in a while. Another thing could be personalizing the experience with well-being history.
