Figure 1: Body LayARs is a toolkit for prototyping body-based AR applications. It offers node-based visual programming, but can also be customized and extended via JavaScript. Applications can be started on connected devices and edited while running. Shown on the right is the output of the application to the left, which tracks faces, detects emotions, and visualizes them as floating emoji. The output was generated with a photo as input to illustrate future AR device's fidelity.
