This is a project that aims to teach fundamentals of Einstein's Theory of Relativity by letting users move about in physical space and simulating their movements in an alternate reality where light moves slower. It aims to provide an intuitive understanding of how the theory of relativity affects objects moving at near-light speeds.
It was developed with Prof. Ira Rothstein, funded by Carnegie Mellon University's ProSEED grant. It involves use of the on-board sensors in Android devices to calculate the velocity and acceleration of users as they walk around in real life and feeds this information into the virtual world where such effects as space contraction and time dilation are exaggerated.

One particularly fun part of the project was developing an algorithm for step detection and velocity estimation of the user. I wrote some notes on my method here:
Here are some screenshots from the actual app
