Abstract
Augmented Reality (AR) is an emerging technology capable of integrating visual technology with the physical world in novel ways. AR uses may range from education delivery to the operating room. This study sought to evaluate cost-effective AR glasses compared to a traditional computer screen when identifying anatomical structures in a chest radiograph (X-ray). The purpose of this experiment was to determine if the Vuzix Blade AR technology is feasible for use in the medical field to identify anatomical structures. Novice undergraduate and graduate students (n = 14) were recruited to participate in this feasibility study. Radio-graphic images were compiled, and subjects were asked to identify 12 anatomical structures on each image. Images were randomly assigned to identify structures using either the AR glasses or a traditional computer screen for each set. Images were viewed randomly by each subject using a crossover design to compare traditional computer screen vs. AR screen. Subjects identified statistically fewer anatomical structures using the AR glasses compared to using the traditional computer screen (p<0.01). However, the glasses did not require significantly more subjective workload (NASA-TLX) on the user to use compared to the computer screen. When subjects used the cost-effective AR glasses, subjects were unable to differentiate as many anatomical structures as possible (10 vs. 9 structures at p < 0.01), but the glasses were not more demanding overall. Thus, AR glasses may soon be an integral part of the operating room, provided adequate resolution to visualize the necessary details.
