Designing Virtual Trailblazing for Battlespace Visualisation

In order to maximize the Common Operational Picture, interactive displays of large-scale complex computerrendered environments must allow for effective navigational techniques. This is no small challenge, given the current state of virtual environment technology, 3D input devices, and limited knowledge regarding human factors-based best practices for human way-finding and navigation. In theory, integrating 3D computer renderings of the real world allows command personnel to plan and simulate battlespace tactics from the perspective of both ground and air. However, change in viewpoints without proper reference points or landmarks can lead to disorientation for the human user. Human factors issues pertaining to navigation in virtual environments and the need to extend the scientific knowledge base concerning ways of effectively improving human navigation in complex or landmark-sparse environments are discussed. In addition, conceptual designs for virtual trailblazing techniques are proposed.
