Query: Redirected Walking in Static and Dynamic Scenes Using Visibility
  Polygons   We present a new approach for redirected walking in static and dynamic scenes
that uses techniques from robot motion planning to compute the redirection
gains that steer the user on collision-free paths in the physical space. Our
first contribution is a mathematical framework for redirected walking using
concepts from motion planning and configuration spaces. This framework
highlights various geometric and perceptual constraints that tend to make
collision-free redirected walking difficult. We use our framework to propose an
efficient solution to the redirection problem that uses the notion of
visibility polygons to compute the free spaces in the physical environment and
the virtual environment. The visibility polygon provides a concise
representation of the entire space that is visible, and therefore walkable, to
the user from their position within an environment. Using this representation
of walkable space, we apply redirected walking to steer the user to regions of
the visibility polygon in the physical environment that closely match the
region that the user occupies in the visibility polygon in the virtual
environment. We show that our algorithm is able to steer the user along paths
that result in significantly fewer resets than existing state-of-the-art
algorithms in both static and dynamic scenes. Our project website is available
