The pace of advancement in emerging display and interface technologies supporting the development of mixed reality systems – those that exploit the existence of real-world objects to enhance the believability of virtual objects – is rapidly increasing. However, the availability of relevant human-system design standards underpinning the exploitation of interfaces is significantly lagging behind. To provide supporting principles to aid in the development and deployment of mixed reality systems, a series of studies was conducted to systematically investigate a range of design parameters relevant to mixed reality, and to determine the impact of those parameters on human-system performance, including cognitive and physical demands. An assessment of specific design standards was undertaken related to the performance of fundamental human-system interaction tasks in a mixed reality system. It was found that mixed reality is most suited to selection tasks, as opposed to more complex interaction tasks such as repositioning and rescaling virtual objects in 3D space. An evaluation was also made of the effects on presence of introducing physical “tangible” interface elements co-located with virtual content. The findings show that tangible interface objects have a significant positive effect on presence, in addition to usability and workload. Finally, an investigation was undertaken to assess the effects of vibration — a common, uncontrollable environmental condition — on human-system performance. Vibration is shown to have a significantly larger impact on accuracy for eye-based input than on head-based input when performing dwell-based interaction. The lowest frequencies have the greatest effect on accuracy, with higher frequencies producing similar effects to instances of zero vibration.
