Old Theories, New Technologies: Developing Guidelines for the Cognitive Ergonomics of Augmented Reality
Research into human factors issues surrounding the use of AR technology is very limited, and there is a need for formal guidelines to underpin human factors integration (HFI). The DERA Centre for Human Sciences (CHS) and the Advanced VR Research Centre (AVRRC) at Loughborough University are evaluating the potential of Augmented Reality (AR) for providing operator feedback in an embedded training system. An important aspect of the research is concerned with investigating the cognitive ergonomics of AR technology and human information processing issues that may arise through its use, when information is presented via AR and overlaid upon one or more primary display surfaces such as a visual display unit. Two main issues have been addressed: first, the impact of AR on human information processing; and, second, the most appropriate symbology sets for displaying information via the AR medium. The experiments reported in this paper assess issues of re-accommodation and reaction times to alarms on different display formats, illustrating that AR performs as well as standard display formats.
