Description

When AR and VR are used to train people in advance or assist them on the fly, users are typically given information about the current task step (cues), either immediately before or while doing it. Many tasks, in the real world and in AR and VR, also use precues about what to do after the current step. We have been exploring how precueing multiple steps in advance in AR and VR can influence performance, for better or for worse. Our work addresses tasks ranging from simple path following to manipulating physical and virtual objects with one or both hands. I will present some of our results on the effectiveness of different numbers and types of precues, and explain their implications for task training and guidance.
