Abstract:

Effective Command and Control C2 requires the rapid comprehension of the identity and other attributes of tracks and other objects in three-dimensional 3-D space. Advances in computing speed and power are enabling display designers to create real-time prototype 3-D displays for this purpose. By 3-D display, we mean a display that shows a perspective projection of all three dimensions of physical space onto a flat CRT. One example of a 3-D prototype C2 display is the Area Air Defense Commander AADC prototype display Dennehy, Nesbitt Sumey, 1994. These new 3-D prototypes are extremely compelling. They offer a radical increase in realism of the scenes they depict over existing 3-D C2 displays. Their naturalistic look and easy feel make them attractive to users who consistently express a strong preference for them. But just because users are clamoring for these 3-D displays and because we can now give them to them does this mean that we should advocate their ubiquitous adoption for C2 The experimental literature comparing 2-D and 3-D displays is large, complicated and contradictory, often showing mixed advantages for 3-D displays, at best. The Navys Perspective Display Technology PVT project has been conducting human factors research addressing these issues. In this talk, an array of PVTs experimental studies is reviewed that offer a consistent - and often counter-intuitive - set of results and guidelines to the where, what and how of 3-D perspective display use for C2 tasks.
