Investigating Display Position of a Head-Fixed Augmented Reality Notification for Dual-task

Hyunjin Lee, Woontack Woo

Abstract: Providing additional information in the proper position of augmented reality (AR) head-mounted display (HMD) can help increase AR performance and usability for dual-task. Therefore, our study inves-tigated how to place notifications for the dual-task to address this. We compared eight display positions and two tasks (single and dual tasks) to identify the appropriate area for displaying notifications. We confirmed that the middle-right reduces response time and task load. In contrast, the top-left is the location, which should avoid providing any notification in AR dual-task. Our study contributes to designing AR notifications on HMDs to enhance everyday AR experiences.
