When two or more users attempt to collaborate in the same space with Augmented Reality, they often encounter conflicting intentions regarding the occupation of the same working area and self-positioning around such without mutual interference. Augmented Reality is a powerful tool for communicating ideas and intentions during a co-assisting task that requires multi-disciplinary expertise. To relax the constraint of physical co-location, we propose the concept of Duplicated Reality, where a digital copy of a 3D region of interest of the users’ environment is reconstructed in real-time and visualized in-situ through an Augmented Reality user interface...

Immersive Virtual Reality can be a memorable medium for story-telling and artistic expression. However, taking snapshots of VR applications is commonly only possible by taking a two-dimensional screenshot on a tethered PC. We propose to capture 3D snapshots using the interaction technique World-In-Miniature (WiM) by using virtual RGB-D cameras to create three-dimensional snapshots that can be exported and viewed outside the application.
We further describe a novel interaction method to fine-tune the content shown inside the WiM with VR controllers. This project is open-source and can be accessed at https://github.com/kyuq/3DWiMSnapshot

A 3D Telepresence system allows users to interact with each other in a virtual, mixed, or augmented reality (VR, MR, AR) environment, creating a shared space for collaboration and communication. There are two main methods for representing users within these 3D environments. Users can be represented either as point cloud reconstruction-based avatars that resemble a physical user or as virtual character-based avatars controlled by tracking the users' body motion. This work compares both techniques to identify the differences between user representations...

Current teleconsultation solutions for preclinical emergencies can transmit knowledge from a remote expert to a local paramedic using audio and 2D video channels. Such technology lacks precision and efficiency for medical diagnostic tasks, and visual feedback is often missing between participants. We investigate a mixed reality 3D teleconsultation solution for preclinical use,...

Intensive care units (ICUs) that host patients infected with COVID-19 through the SARS-CoV-2 Coronavirus are typically separated from other care units in the hospital. In typical ICU ward rounds, a number of multidisciplinary experts from different medical areas and expertise levels are present to discuss the situation and care of the patient. However, this procedure is contrasting the current COVID-19 recommendations regarding contact and personnel traffic. In this project, we demonstrate a system for mixed reality (MR) teleconsultation to support ICU wards (RTKMD)...

When users create hand-drawn annotations in Virtual Reality they often reach their physical limits in terms of precision, especially if the region to be annotated is small. One intuitive solution employs magnification beyond natural scale. However, scaling the whole environment results in wrong assumptions about the coherence between physical and virtual space. In this paper, we introduce Magnoramas, a novel interaction method for selecting and extracting a region of interest that the user can subsequently scale and transform inside the virtual space...
