  The field of Augmented Reality (AR) based Human Robot Interaction (HRI) has
progressed significantly since its inception more than two decades ago. With
more advanced devices, particularly head-mounted displays (HMD), freely
available programming environments and better connectivity, the possible
application space expanded significantly. Here we present concepts and systems
currently being developed at our lab to enable a truly end-to-end application
of AR in HRI, from setting up the working environment of the robot, through
programming and finally interaction with the programmed robot. Relevant papers
by other authors will also be overviewed. We demonstrate the use of such
technologies with systems not inherently designed to be collaborative, namely
industrial manipulators. By trying to make such industrial systems
easily-installable, collaborative and interactive, the vision of universal
robot co-workers can be pushed one step closer to reality. The main goal of the
paper is to provide a short overview of the capabilities of HMD-based HRI to
researchers unfamiliar with the concepts. For researchers already using such
techniques, the hope is to perhaps introduce some new ideas and to broaden the
field of research.
