Abstract
While human factors have been well researched in the development and use of virtual environments, it has not received commensurate consideration in Mixed Reality (MR) research much beyond the immediately relevant issues of fatigue and discomfort. In this paper, we (1) analyze the feasibility of augmenting human abilities via MR applications in tasks for assembly and related domains from the perspective of cognitive engineering, (2) acknowledge the ergonomics features and research issues inherent in MR systems, and (3) generate partial guidelines that have been applied in our lab-based Augmented Reality prototype to uncover and solve ergonomics issues. One of such issues, perceptual compatibility, was also validated through a pilot experiment that compares use of a head mounted display versus a standalone monitor in performing an orientation task. It was found that subjects using the HMD perform in less time, exhibit less orientation displacement, and experience less cognitive load.
