Analysis of Instructional Techniques Influence on a Robot Assembly Task

As virtual reality (VR) has grown to become a common medium for training and entertainment, the techniques for communicating and instructing the user to perform a task within VR have been diverse and varied. Some of these techniques utilize familiar patterns such as dialogs and textual instructions, while others provide more VR-native interactions such as environmental cues or holograms. In this study, each subject was tasked with assembling two robots from their constituent parts one piece at a time. The subject received the instruction through one of the following instructional techniques: an unchanging set of generic instructions, a dynamic line of text per part, an image of the robot highlighting each part's destination, and a hologram in the destination of where each part should be placed. We conclude that no instructional technique offered a statistically significant increase in performance. While the hologram instructional technique was the overall preference of the population. Finally, the analysis of feedback shows promise that holograms would solve issues demonstrated in other instructional techniques.
