Comparative Analysis of Mixed Reality Screen Extensions and Laser Safety Goggles in Laser Laboratories

In laser laboratories, user ergonomics and visibility are key concerns. Users must concentrate on small surfaces by watching telescope- generated images displayed on the screen to conduct measurement. Through a mixed reality head-mounted display (MR-HMD), they see the real world while being physically separated from hazardous laser radiations and can view telescope images on the HMD at the same time. In this poster, we conducted a comparative analysis of an MR screen extension versus a traditional laser safety goggle (LG) during an optical observation task in a laser laboratory. Results from our user study indicate that the MR condition significantly outperformed the LG condition in terms of speed and user preference.
