Fig. 14.1 Walkthrough of the pointing task in the spatial orientation experiment. a Participants
pointed at a target in the real world. b Next, they put on the head-mounted display and pointed at
a visible target in the virtual world. c-d After being redirected by 90 , participants pointed back to
where the thought the real and virtual targets were. Participants generally pointed to target positions
as if they had been rotated along with the virtual world, instead of their original locations
14.3.2 Augmenting Effectiveness of Redirected Walking
In order to increase the utility of redirected walking in immersive training scenar-
ios, we have explored possibilities for augmenting the magnitude of redirection that
can be achieved without becoming noticeable to the user. In particular, the interface
between the ground and the user's feet is frequently taken for granted, but if floor con-
tact can be manipulated, it may be possible to more strongly curve the user's walking
path. To probe this effect, we constructed shoe attachment prototypes designed to
