Redirected walking techniques enable natural locomotion through
immersive virtual environments (VEs) that are larger than the real
world workspace. Most existing techniques rely upon
manipulating the mapping between physical and virtual motions
while the layout of the environment remains constant. However, if
the primary focus of the experience is on the virtual world´s
content, rather than on its spatial layout, then the goal of
redirected walking can be achieved through an entirely different
strategy. In this paper, we introduce flexible spaces - a novel
redirection technique that enables infinite real walking in virtual
environments that do not require replication of real world layouts.
Flexible spaces overcome the limitations and generalize the use of
overlapping (impossible) spaces and change blindness by
employing procedural layout generation. Our approach allows VE
designers to focus on the content of the virtual world independent
of the implementation details imposed by real walking, thereby
making spatial manipulation techniques more practical for use in a
variety of application domains.
