We use a tiny actuated projector that is attached directly to an AR HMD to enhance the user's environment by projection mapping content. This gives the AR user a way to enhance their environment outside the headsets field-of-view while also solving some issues related to accommodation-vergence conflicts (VAC) by projection mapping to nearby surfaces.
Crucially however is the affordances this can provide when communicating with external, non-augmented user. The projector can be used as a bridge between the real unaugmented world and the virtual environment the AR user resides in. Imagine if you could show a collaborator a 3D model by using a perspective mapping so it looks 3D to the external user? Or collaborate on documents through an ad-hoc large display? These are some of the designs we look at in the paper, so if that sounds interesting, check it Github repo and paper!
