“…Such co-located AR systems are beneficial for intensive collaborative work such as 3D modeling (Fig. 2, bottom, [31]) since discussions and exchanging ideas between participants can happen more naturally and smoothly due to non-verbal communication cues present while sharing and viewing virtual content [32]. These developments allowed for the sharing of virtual content between users from different perspectives, but bandwidth requirements were minimal for demonstrating the basic technology.…”

Abstract:In recent years, virtual and augmented reality have begun to take advantage of the high speed capabilities of data streaming technologies and wireless networks. However, limitations like bandwidth and latency still prevent us from achieving high fidelity telepresence and collaborative virtual and augmented reality applications. Fortunately, both researchers and engineers are aware of these problems and have set out to design 5G networks to help us to move to the next generation of virtual interfaces. This paper reviews state of the art virtual and augmented reality communications technology and outlines current efforts to design an effective, ubiquitous 5G network to help to adapt to virtual application demands. We discuss application needs in domains like telepresence, education, healthcare, streaming media, and haptics, and provide guidelines and future directions for growth based on this new network infrastructure.

We describe an Augmented Reality system which allows multiple participants to interact with 2D and 3D data using tangible user interfaces. The system features face-to-face communication, collaborative viewing and manipulation of 3D models, and seamless access to 2D desktop applications within the shared 3D space. All virtual content, including 3D models and 2D desktop windows, is attached to tracked physical objects in order to leverage the efficiencies of natural two-handed manipulation. The presence of 2D desktop space within 3D facilitates data exchange between the two realms, enables control of 3D information by 2D applications, and generally increases productivity by providing access to familiar tools.We present a general concept for a collaborative tangible AR system, including a comprehensive set of interaction techniques, a distributed hardware setup, and a componentbased software architecture which can be flexibly configured using XML. We show the validity of our concept with an implementation of an application scenario from the automotive industry.

“…In contrast, AR interfaces using head mounted displays (HMDs) allow virtual objects to be shown at arbitrary locations, such as in front of a partner's face [7][11] [12]. Another advantage of HMD-based interfaces is that they have the potential capability of showing correct occlusion phenomena between virtual and real scenes.…”

An ideal augmented reality (AR) display for multi-user co-located collaboration should have following three features: 1) Any virtual object should be able to be shown at any arbitrary position, e.g. a user can see a virtual object in front of other users' faces. 2) Correct occlusion of virtual and real objects should be supported.3) The real world should be naturally and clearly visible, which is important for face-to-face conversation. We have been developing an optical see-through display, ELMO (Enhanced see-through display using an LCD panel for Mutual Occlusion), that satisfies these three requirements. While previous prototype systems were not practical due to their size and weight, we have come up with an improved optics design which has reduced size and is lightweight enough to wear. In this paper, the characteristics of typical multi-user three-dimensional displays are summarized and the design details of the latest optics are then described. Finally, a collaborative AR application employing the new display and its user experience are explained.
