abstract = {We present PerspectAR, a novel system addressing perspective distortion on displays caused by large size and wide viewing angles. PerspectAR has three components: a virtual AR screen that curves dynamically according to a user’s position relative to the display, a sliding transparent window giving unobstructed access to the physical display in front of the user, and gaze indicators to assist collaborators when they are looking at different renderings. In a within-subjects study in a semi-controlled public environment with 12 pairs, we compared physical display-only and PerspectAR configurations for data analysis tasks. Participants reported less physical workload with PerspectAR and spent more time near the physical display without compromising task performance. Feedback indicates that PerspectAR addressed perspective distortion and provided a contextual view that was useful as a memory aid. Due to the virtual screen curvature, PerspectAR was seen as less effective for tasks involving distance estimates between objects.},

abstract = {Museums are constantly searching for new ways to increase engagement with their exhibits, from electronic guides to modern digital technologies such as special-purpose tablets, smartphones, and virtual and augmented reality (AR). For AR exhibits in particular, promoting shared experience and group cohesion is not straight-forward. In this work, we investigate scenarios in which not everyone is using a head-worn display (HWD), either because there aren’t enough available or simply because someone might feel uncomfortable using it.We propose three sharing techniques for AR experiences and evaluate them in a long term in-the-wild study: Over-the-Shoulder AR, which renders a real-time virtual representation of the augmented reality content on a large secondary display; Semantic Linking, which displays contextual information about the virtual content on the same large display; and Indicator Rings, which display the locations of the HWD user’s objects-of-focus. We observed that participants in theOver-the-Shoulder AR and Semantic Linking conditions stayed together and exhibited more verbal exchanges than participants in a Baseline condition, which could indicate that they were more engaged. Self-reported measures indicated an increase in pair communication and increased comprehension of the virtual content for participants without the HWD. Participants without the HWD also displayed a greater understanding of the location of virtual elements with support from theIndicator Rings, and used them as a tool to guide the HWD user through the virtual content. We discuss design implications for interactive augmented reality exhibits and possible applications outside the cultural heritage scenario.},
