The Omni-Directional Treadmill (ODT) is a revolutionary device for locomotion in large-scale virtual environments. The device allows its user to walk or jog in any direction of travel. It is the third generation in a series of devices built for this purpose for the U.S. Army's Dismounted Infantry Training Program. We first describe the device in terms of its construction and operating characteristics. We then report on an analysis consisting of a series of locomotion and maneuvering tasks on the ODT. We observed user motions and system responses to those motions from the perspective of the user. Each task is described in terms of what causes certain motions to trigger unpredictable responses causing loss of balance or at least causing the user to become consciously aware of their movements. We conclude that the two primary shortcomings in the ODT are its tracking system and machine control mechanisms for centering the user on the treads.

People have severe problems wayfinding in large virtual worlds. However, current implementations of virtual worlds provide little support for effective wayfinding. We assert that knowledge about human wayfinding in the physical world can be applied to construct aids for wayfinding in virtual worlds. An experiment was conducted to determine whether people use physical world wayfinding strategies in large virtual worlds. The study measures subject performance on a complex searching task in a number of virtual worlds with differing environmental cues. The results show that subjects in the treatment without any additional cues were often disoriented and had extreme difficulty completing the task. In general, subjects' wayfinding strategies and behaviors were strongly influenced by the environmental cues in ways suggested by the underlying design principles.

As important as navigation is to human performance in virtual worlds, it is an often overlooked problem in the design process. This article reports an experiment intended to show that real-world wayfinding and environmental design principles are effective in designing virtual worlds that support skilled wayfinding behavior. The study measures participant performance on a complex searching task in a number of virtual worlds with differing environmental cues. The worlds are augmented with either a radial grid, a map, or both a grid and a map. The control condition provided no additional navigational cues. The results showed that navigational performance was superior under both map treatments as compared to the control and grid conditions. The grid was, however, shown to provide superior directional information as compared to the other conditions. The control condition provided the worst performance, with participants often becoming disoriented and experiencing extreme difficulty completing the tasks.

Maintaining knowledge of current position and orientation is frequently a problem for people in virtual environments. In this paper we present a toolset of techniques based on principles of navigation derived from real world analogs. We include a discussion of human and avian navigation behaviors and show how knowledge about them were used to design our tools. We also summarize an informal study we performed to determine how our tools influenced the subjects' navigation behavior. We conclude that principles extracted from real world navigation aids such as maps can be seen to apply in virtual environments.
