The effect of AR guidance on locating maintenance items: A use case
MetadataShow full item record
Efficient maintenance is critical for the U.S. Navy to sustain surface fleet operational readiness, capability, and capacity. Efficient maintenance relies on the ability to quickly locate needed maintenance items. The current process to locate critical maintenance items relies on the written description of a work order, which offers little description and ambiguity of the exact physical location of the maintenance item, creating inefficiencies in repairs, and cost and schedule delays. Augmented Reality (AR) has been shown to improve maintenance efficiency in the private sector; we provide empirical evidence to suggest the U.S. Navy should consider AR adoption for maintenance for certain use cases. We conducted an experiment in which 20 subjects were randomly assigned to locate visible unobstructed objects in two rooms that represented shipboard compartments using either the current maintenance process or with AR guided assistance. Performance was measured by time to locate items, accuracy, and the confidence in having identified the proper item. Results indicated that use of AR guidance led to considerably better performance on all measures, in terms of both statistical significance and practical importance. This research shows evidence that AR can potentially close the capability gap existing within the current process.
