Augmented Reality Annotations in a Collaborative Time-Critical Task

This research explores the use of Augmented Reality (AR) annotations for assisting with performance, decision-making, and collaboration in a time-critical task. A user study was conducted to compare the use of AR with and without annotations, as well as the use of an attention-guiding technique. The results revealed that participants felt more confident in making timely and informed decisions when having access to annotations. Performance metrics indicated that the consumption of AR annotations adds cognitive overhead, however, they are not detrimental to achieving task goals. These findings pave the way for further development and investigation of AR systems for assisting with performance, decision-making, and collaboration in time-critical tasks.
