A Survey of Augmented Reality Technologies, Applications and Limitations

This paper presents a novel mediated reality system designed to support collaboration between crime scene investigators during a first analysis on a crime scene, remotely supported by expert colleagues. Requirements elicited from interviews and interactive sessions with practicing crime scene investigators, provided the design criteria for a head mounted display capable of real-time map-making for spatial collaboration. The resulting system is evaluated in a staged crime scene experiment in which lay investigators collaboratively solve a spatial problem with remote experts. The results show that our novel approach to remote spatial interaction with the physical scene enables investigators to tackle current issues on site in collaboration with experts at a distance. Human Factors; Design; Measurement.The design and evaluation of the mediated reality system is the focus of the paper in which five phases are distinguished: (1) requirement capture from international experts, (2) initial design of a mock-up system, (3) evaluation of mock-up by practitioners, (4) design of the mediated system, and (5) evaluation of the mediated reality system for collaboration. After discussing related work the remainder of the paper discusses the above five phases in 1 Please note that consideration of the implications of such new technology on the organization itself as discussed in [16] are beyond the scope of this project Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.
