This study evaluated the effectiveness of spatially overlaid instructions using augmented reality (AR) in an assembly task compared with other traditional media. Results indicate that overlaying 3D instructions on the workspace reduce error rate by 82%, particularly cumulative errors. Measurement of mental effort also suggests some of the mental workload is offloaded to the computer.
