Abstract: Methods, systems, and techniques for enhancing a live sporting event using augmented reality are provided. Example embodiments provide an Augmented Reality Live Game Enhancement System (“ARLGES”), which enables users to see augmentations appear as if they are “live” on the sports field as they are watching the game. The user is able to see and interactive with these augmentations using his or her mobile device without taking his or her eyes off of the field. In some deployments, the mobile device is a cellular smartphone with an (optional) modified virtual headset. The user can view the augmentations using the camera of the phone. The ARLGES provides specific techniques for locating the user's position and for rendering augmentations that are specific to each user. This requires specialized rendering techniques because the user's mobile device positions and chroma values are determined dynamically as they do not originate from fixed or known cameras.
