Telepresent walking creates the sensation of walking through a
target environment, which is not directly accessible to a human,
e.g. because it is remote, hazardous, or of inappropriate scale. A mobile teleoperator replicates user motion and collects visual
and auditory information from the target environment, which is
then sent and displayed to the user. While walking freely about the user environment, the user perceives the target environment with the sensors of the teleoperator and feels as if walking through the target environment. Without additional processing of the user's motion data, the size of the target environment to be explored is limited to the size of the user environment. Motion compression extends telepresent walking to arbitrarily large target environments without making use of scaling or walking-in-place metaphors. Both travel distances and turning angles are mapped with ratio 1:1.
