Mixing realities in Shared Space: an augmented reality interface for collaborative computing

Application that adopts collaborative system allows multiple users to interact with other users in the same virtual space either in Virtual Reality (VR) or Augmented Reality (AR). This paper aims to integrate the VR and AR space in a Collaborative User Interface that enables the user to cooperate with other users in a different type of interfaces in a single shared space manner. The gesture interaction technique is proposed as the interaction tool in both of the virtual spaces as it can provide a more natural gesture interaction when interacting with the virtual object. The integration of VR and AR space provide a cross-discipline shared data interchange through the network protocol of client-server architecture.

The concept of internet of everything involves an intelligent connection of people, processes, data, and things. In this sense, shared spaces aimed to connect different users that collaborate following a common purpose are of relevance to the field. Many computer-based collaborative environments have been proposed in recent years. However, the design of mixed-platform collaborative spaces, in which different paradigms—such as augmented reality (AR) and virtual reality (VR)—are blended, is still uncommon. This chapter aims to analyze the benefits and features of these systems, reviewing existing related works and proposing a series of features for the design of effective mixed-platform collaborative shared spaces. In particular, the authors propose five setups with different levels of immersion/interaction, which are aligned to the current state of the art. These systems will be analyzed with respect to navigation, user representation, interaction, and annotation, among others. Finally, some applications are proposed within the given framework.

Abstract. Augmented Reality (AR) in a traffic context has mainly been used in navigation with path augmentation, focused around safely guiding the user with prior knowledge of the route and the destination. Other works are reported to warn drivers by visualizing other traffic participants or dangers, which are yet currently out of sight. However they do not cover aspects of mediating control by recommending users with actions, even when such efforts are expected to foster collaboration in a multiagent environment. To the best of our knowledge, AR has not yet been applied to visualize virtual control information, e.g. virtual lanes or signposts, notably in the context of shared spaces. Such an environment should support spatial understanding of proximate participants with adaptive augmented controls to recommend actions to each user. However when such systems work in context where a conflict of interest would arise, a rule based control logic centered on priority should be accounted for. Traditionally, these rules are defined by traffic management. This paper presents a Behaviour Control with AR (BCAR) Systems based framework for control of user behaviour in a shared space via augmentation and proposes how a control logic can be part of it. The framework which incorporates navigation focuses on mapping users from real to the virtual world .This framework also enables simulations and visualization of multiagent interactions and proposing controls for user actions leveraging the environment complexity reduction achieved through the real to virtual transfer. A prototype implementation of the proposed framework with ARCore and unity3D has been evaluated for pedestrian behaviour control to understand its feasibility.
