EgoSAR: Towards a Personalized Spatial Augmented Reality Experience in Multi-user Environments

Abstract

(a) active scenario (b) passive scenario (c) augmentations Figure 1: Our vision of EgoSAR. (a) In an active scenario, the users are wearing or holding a projector that augments a real artifact in a personalized way: the respective augmentation can only be seen by themselves. (b) In a passive scenario, the users look at a real object from predefined viewpoints. Each viewpoint offers a different augmentation and is thus personalized. (c) In both scenarios, the real-world object and the personalized virtual information are visible. The view-dependent personalized information such as curvatures can be superimposed on the object (c-top) or shown aside, for example for annotations (c-bottom).

Bioinformatics and the Metaverse: Are We Ready?

“…A key factor is development of XR hardware that each have different features and tradeoffs (such as display, weight, price etc). Can XR wearables become inexpensive and light enough so that they become part of an everyday experience whilst respecting privacy ( Lebeck et al, 2018 ; Ridel et al, 2016 )? Visualization research offers exciting possibilities for maximizing the metaverse’s promise.…”

Revealable Volume Displays: 3D Exploration of Mixed-Reality Public Exhibitions

“…Projected information is however limited to the surface of the exhibited objects and might damage fragile artefacts. The same authors also describe EgoSAR, an augmented reality display that superimposes personalised virtual content for different viewers around a physical object [27]. The system is based on retro-reflective material combined with multiple light sources.…”

Smart Discovery of Cultural and Natural Tourist Routes

“…These include indoors and outdoors location tracking using Markerless object recognition [28], activity recognition, semantic representation, context-aware AR visualization and human-objects interaction [29]. Last but not least, the above technologies when combined with Personalization can increase the user satisfaction (personalzed augmentation) [30].…”
