This project examines the use of augmented reality (AR) smart glasses to provide real-time sign language interpretation and captioning for Deaf and Hard of Hearing (DHH) students in hands-on learning environments like science laboratories. Here, we evaluate the feasibility and trade-offs of AR-mediated access, focusing on reducing visual split attention and cognitive load during practical tasks. Additionally, our efforts investigate the broader educational ecosystem by assessing how heads-up displays impact interaction, pacing, and visual coordination among instructors, sign language interpreters, and captioners.
