a
The user
walks down the gravel path and enters the first virtual building.
b
The user enters the back room
of the building. When the user searches through the crates, the door behind him is moved.
c
The
user exits and continues down the same gravel path. The original layout is restored as the user
approaches the second virtual building
14.5 Challenges and Future Directions
In this section, we discuss the practical challenges and future directions towards
transitioning redirected walking in active training environments, based on feedback
we have received from public demonstrations and discussions with domain experts
and military personnel.
Automated redirection in arbitrary environments
. Much of the previous research
has focused on purpose-built environments with constrained scenarios designed to
test individual techniques. However, in a practical training setting, users will not
always follow the designer's expectations. Such a system would need to be able
