Mr. Truman - An Embedded Friend

We created a virtual person that lives in a 3D printed house. You can interact with him via voice control, by plugging in a 3.5mm cable to your phone, or tilting him. The idea behind Mr. Truman is to have a virtual person inside the house interact with the real-world house. Check out this short video for a full demonstration of the project in action plus details on the components and design.

This project was created for our ECE 453 Embedded Capstone course at the University of Wisconsin-Madison. We wanted to run with the idea of an animated man who had a house he interacted with. We picked the DragonBoard™ 410c to power it as we needed a dedicated GPU to power our graphics and handle our voice recognition audio processing. We wanted a project that people would say "that's so cool" when they saw it.
