Virtual environments are increasingly used to visit virtual mockups of proposed buildings or virtualized models of real sites or buildings. This paper presents the results of a human-machine interaction experiment aimed at measuring the effects of the real field-of-view (FOV) and of the use of a third joystick axis on human performance for navigation in virtual walkthroughs in a closed-space environment. The results indicate that neither the real FOV nor the third joystick axis significantly affect performance. There is however a perceived increase of immersion with the larger real FOV, and an added freedom of movement when a third axis of movement is mapped onto the joystick.
