Recent advancements in augmented reality (AR) technologies have brought us closer to the vision of everyday ubiquitous computing and pervasive AR use. State-of-the-art AR glasses now enable mobile, on-the-move experiences that extend beyond laboratory settings. This promise has already been explored across diverse mobile contexts, including transportation, entertainment, shopping, and tourism. This workshop focuses on AR on-the-move, examining how AR can support interaction in dynamic settings where environmental and social contexts shift rapidly and users are in locomotion. We will discuss both the unique challenges and the rich opportunities such scenarios present for meaningful augmentation and new forms of interaction. By uniting established scholars and emerging researchers from across HCI, this workshop seeks to map out critical directions for future inquiry. Through hands-on activities and reflection, participants will collectively identify key opportunities, challenges, and next steps for advancing research on AR on-the-move.
