  Human teams exhibit both implicit and explicit intention sharing. To further
development of human-robot collaboration, intention recognition is crucial on
both sides. Present approaches rely on a vast sensor suite on and around the
robot to achieve intention recognition. This relegates intuitive human-robot
collaboration purely to such bulky systems, which are inadequate for
large-scale, real-world scenarios due to their complexity and cost. In this
paper we propose an intention recognition system that is based purely on a
portable head-mounted display. In addition robot intention visualisation is
also supported. We present experiments to show the quality of our human goal
estimation component and some basic interactions with an industrial robot. HAIR
should raise the quality of interaction between robots and humans, instead of
such interactions raising the hair on the necks of the human coworkers.
