Compatibility issues in augmented reality systems for AEC: An experimental prototype study

While human factors have been well researched in virtual environments, it has not received commensurate consideration in Mixed Reality (MR) research. This paper (1) analyzes the feasibility of augmenting human abilities via MR applications in construction tasks from the perspective of cognitive engineering, (2) acknowledges the ergonomics features and research issues in MR systems, and (3) generates partial guidelines to solve ergonomics issues. Also, perceptual incompatibility was validated through an experiment comparing a head mounted display versus a desktop monitor in performing an orientation task. The perceptual incompatibility by using the monitor was significant regarding performance time, accuracy and workload. (c) 2005 Elsevier B.V. All rights reserved.
