Abstract
In one embodiment, a method includes receiving light signals from an interaction device, where the captured light signals are processed into one or more images that include illumination patterns associated with one or more objects, accessing light signals only within a particular spectrum range, detecting one or more tracking patterns from the accessed light signals within the particular spectrum range, where each of the one or more tracking patterns indicates a particular portion of a first object, and where the first object is a part of the one or more objects, determining one or more characteristics of the first object based on the detected one or more tracking patterns, and sending one or more content items and instructions causing a projector to project the one or more content items on the first object to the interaction device.
