We assessed the effects of augmented reality (AR) on learning. We developed an AR manual installed on smart glass and compared it with the conventional paper manual. Forty-nine students in clinical engineering, without experience in hemodialysis priming were randomly recruited to prime hemodialysis units using either a conventional manual (CM; n = 28; male, n = 15) or the AR manual (n = 18; male, n = 7). We measured the amount of the time required to complete the task, accuracy (number of failed processes/number of total processes), and the ratio of persons who did not complete the task. The results were compared between the CM group (CMG) and the AR group (ARG) at baseline and after two and four weeks, and the abilities of both groups to perform the task without a manual were compared three months later. The time in the ARG shortened faster. Accuracy in the ARG was initially inferior, but improved each time, eventually, it was superior to the CMG. The ratio of ARG was superior, but when the tasks were done without the manual, the CMG was superior. These results suggested that AR may be effective for learning medical technologies.
