Visualizing Spinors in Augmented Reality

Spin-one-half particles have unintuitive transformation properties under changes of coordinates: It takes two full rotations to return a spinor wavefunction to its original value. Here we apply the rapidly evolving techniques of augmented reality to develop a quasi-physical model of a spinor. We describe the connection between augmented reality, quaternions, and spinor transformations, and present a prototype mobile application as a proof-of-concept for future educational use.
