Abstract
In Virtual Reality, real walking is a natural and intuitive form of navigation. With real
walking the user physically walks to move in a virtual environment. However, with
real walking the size of the physical space needs to match the virtual space. This is
rarely feasible, especially for large virtual worlds. Redirected Walking seeks to solve
this problem by decoupling the mapping between the virtual trajectory of the user
and their physical movement. There are two broad categories of redirected walking.
Gain manipulation changes how the user’s viewpoint is moved. For example, the
user might turn at a different rate in the virtual environment than they are physically
turning. This is called rotation gain. Environment manipulation changes the virtual
environment itself - for example an expanding room.
This work aims to reduce the amount of physical space required for redirected
walking while balancing the impact of redirected walking on user experience. The first
part of this work looks at the performance of existing generalised redirected walking
methods in a small tracking space. It was found that these existing methods have
limited use in such small tracking spaces at levels that are comfortable for users. Next
we look at the turning accuracy of users with larger rotation gain. We found, for
example, at higher rotation gain levels users turned more than expected and the visual
detail of the virtual environment impacted their turning accuracy.
Finally, based on these findings, a new method of virtual rotation is created: Segment
Addition. With Segment Addition the virtual environment expands and contracts
around the user so they must turn further or shorter to reach their goal. It is
an example of an environmental manipulation method. A user study using Segment
Addition found the environment natural and comfortable for users even when large
changes were made to the virtual environment. This demonstrates Segment Addition
as a promising new technique for redirecting users in small tracking spaces.
