  Technological advances in holography, robotics, and 3D printing are starting
to realize the vision of a holodeck. These immersive 3D displays must address
user safety from the start to be viable. A holodeck's safety challenges are
novel because its applications will involve explicit physical interactions
between humans and synthesized 3D objects and experiences in real-time. This
pioneering paper first proposes research directions for modeling safety in
future holodeck applications from traditional physical human-robot interaction
modeling. Subsequently, we propose a test-bed to enable safety validation of
physical human-robot interaction based on existing augmented reality and
virtual simulation technology.
