It was found through these experiments that the presence of camera control impacts on operator performance:
- - No camera control results in the best seek time for victims.
- - Camera control increases seek time.
- - Head tracked control performs better than manual control.
Furthermore, it was shown that the different camera control techniques have no impact on the number of collisions.
These results are suprising as one would expect camera control to decreases seek time as well as the number of collisions. We found that users spent more time stationary when they had camera control and this negatively impacted upon their performance. Users with head tracked camera control could move while controlling the camera, which resulted in their better performance. Again the use of the laser scanner was of geater value in avoiding obstacles than camera control.
