In-Depth Information
Some users find that stereoscopic viewing enhances their spatial understanding, however
such display systems should only be used for brief viewing sessions (e.g. up to half an hour)
to avoid simulator sickness (Louka & Balducelli, 2001).
For a greater sense of immersion, multi-screen projection systems or head-mounted displays
can be used to place the viewer inside the model. While the hardware required to do this
efficiently, with motion tracking and 3D input devices such as gloves, is relatively costly,
immersive VR is particularly useful if a realistic view of a virtual environment is required.
The user experiences the environment within the model as opposed to looking into it from
the outside. VR systems based on immersive technology are relatively expensive, but can be
justified when the benefits outweigh the cost (Louka & Balducelli, 2001).
In order to create usable virtual reality systems at a reasonable cost and with an appropriate
level of performance, the application designer's understanding of the advantages and
limitations of combinations of VR hardware and software is crucial (Louka & Balducelli, 2001).
