  Spatial computing -- the ability of devices to be aware of their surroundings
and to represent this digitally -- offers novel capabilities in human-robot
interaction. In particular, the combination of spatial computing and egocentric
sensing on mixed reality devices enables them to capture and understand human
actions and translate these to actions with spatial meaning, which offers
exciting new possibilities for collaboration between humans and robots. This
paper presents several human-robot systems that utilize these capabilities to
enable novel robot use cases: mission planning for inspection, gesture-based
control, and immersive teleoperation. These works demonstrate the power of
mixed reality as a tool for human-robot interaction, and the potential of
spatial computing and mixed reality to drive the future of human-robot
interaction.
