Project title: Understanding disorientation in cluttered virtual environments
Investigators: Simon Lessels and Dr Roy Ruddle
Funding: EPSRC Grant GR/R55818/01 (2001-4)
The overall objective of this project is to investigate the factors that contribute to the difficulty people have maintaining their orientation in virtual environments. To do this we are continuing previous EPSRC-funded studies (the virtual humans project), using a navigational task in which participants search room-sized, cluttered spaces for targets that in known, possible locations.
Our investigations started with a recreation of the task in a real-world environment, and are continuing by attempting to measure the thresholds for efficient navigation in terms of:
|
|
| Real-world scene | |
|
|
| High-fidelity virtual scene normal (48 degree) FOV |
Low-fidelity virtual scene normal (48 degree) FOV |
|
| |
| High-fidelity scene, wide (144 degree) FOV | |
