Truxler, Robert, Roth, Emilie, Scott, Ronald, Smith, Stephen and Wampler, Jeffrey (2012): Designing Collaborative Automated Planners for Agile Adaptation to Dynamic Change. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 223-227.

“A common characteristic of domains that require planning for allocation of scarce resources is the need to dynamically revise the plan as new requirements emerge and priorities change. We describe a prototype decision support system for planning and scheduling airlift that we developed for a military transport organization that enables agile plan adaptation as movement requirements, available airlift assets, and priorities change. The collaborative automated scheduler includes visualizations to foster improved situation awareness of available airlift assets versus total demand on those assets; mechanisms to enable users to communicate informal priorities and changes to those priorities; and mechanisms that enable users to explore alternative scheduling options in response to changes in movement requirements, priorities and available assets. A formal user evaluation study that included 12 participants representing three different organizational groups involved in transportation planning provided evidence that the prototype improves the ability to capture and communicate movement priorities, rapidly reallocate airlift assets to accommodate changes, and communicate/collaborate across organizational boundaries in managing airlift demand versus capacity.”

Ellis, Stephen R., Tharp, Gregory K., Grunwald, Arthur J. and Smith, Stephen (1991): Exocentric Judgements in Real Environments and Stereoscopic Displays. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 1442-1446.

“Spatial direction errors during interpretation of perspective images, such as 3D map displays, may originate from misjudgment of the orientation of the viewing direction used to make the display. One source of these errors could be perceptual evidence of the display surface. Two experiments are reported in which the same judgement exocentric task was presented, but the cues to the picture surface were reduced or eliminated by presenting the task as a stereoscopic, virtual image or by a geometrically matched physical model. A theory developed to model exocentric direction errors on perspective displays has been fitted to the data from these two experiments. The parameters estimated from the fit in both experiments indicate that the subjects may be more correctly estimating the viewing direction than in ordinary perspective displays. Consequently, in some real world or stereo viewing conditions, errors in estimating the viewing direction are not likely to dominate exocentric direction errors.”

Ellis, Stephen R., Smith, Stephen and Hacisalihzade, Selim (1989): Visual Direction as a Metric of Virtual Space. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1392-1395.

“Two experiments examine the abilities of 10 subjects to visualize directions shown on a perspective display. Subjects indicated their perceived directions by adjusting a head-mounted cursor to correspond to the direction depicted on the display. This task is required of telerobotic operators who use map-like pictures of their workspace to determine the direction of objects seen by direct view. Results show significant open-loop, judgements biases that may be composed of errors arising from misinterpretation of the map geometry and overestimation of gaze direction.”
