Head Tracker software for helicopter pilots to make use of AR (Augmented Reality) within their displays, they need to have their head movements tracked accurately and with little latency. Our project is a low cost, accurate, and low-latency implementation of a head tracker that is designed for pilots. By combining a Raspberry Pi, 6 IMU sensors, and software, we can display and track an accurate location of the pilots head. Team CS28: Eric Sisson, Jianlong Huang, and Savannah Loberger
