AR and VR can provide cues and precues to assist users in completing manual tasks more efficiently. Previous research has focused on simple tasks, but we examined a more complex task and found that providing continuous movement information and single rotation information yielded the best results through two user studies.
When a user is performing a manual task, AR or VR can provide information about the current subtask (cueing) and upcoming subtasks (precueing) that makes them easier and faster to complete. Previous research on cueing and precueing in AR and VR has focused on path-following tasks requiring simple actions at each of a series of locations, such as pushing a button or just visiting. We consider a more complex task, whose subtasks involve moving to and picking up an item, moving that item to a designated place while rotating it to a specific angle, and depositing it. We conducted two user studies to examine how people accomplish this task while wearing an AR headset, guided by different visualizations that cue and precue movement and rotation. Participants performed best when given movement information for two successive subtasks and rotation information for a single subtask. In addition, participants performed best when the rotation visualization was split across the manipulated object and its destination.
