Abstract
In three experiments, participants made judgments about the properties of two points placed on terrain depicted as 2D or 3D displays. Participants performed the tasks in pairs of trials, switching tasks and displays between trials. On half the trials (continuous transition), the display dynamically rotated in depth from one display format to the other. The design of the control condition (discrete transition) varied across experiments (Experiment 1: blank screen; Experiment 2: no delay: Experiment 3: terrain preview). In general, the results showed that performance improved more for the continuous transition than the discrete transition condition. The relative effectiveness of 2D and 3D displays in a task-switching context was found to be task dependent although a speed-accuracy tradeoff was also observed.
