“…This has been shown to improve performance in a wide variety of contexts including bioinformatics (Baehrecke et al 2004), medicine (Tominski, Schulze-Wollgast, and Schumann, 2008), databases (Shneiderman, 2008), and e-Learning (Aguilar, Theron, and Peñalvo, 2009). Furthermore, visualizations can be improved by employing immersive virtual environments (van Dam et al, 2000) such as a Cave automatic virtual environment (CAVE; Cruz-Neira et al, 1992;Demiralp et al, 2003). A CAVE typically comprises three to six projectors arranged to display data on the walls of a room-sized cube, creating an environment that surrounds the user and provides a sense of immersion.…”

While simple heuristics can be ecologically rational and effective in naturalistic decision making contexts, complex situations require analytical decision making strategies, hypothesis-testing and learning. Sub-optimal decision strategies -using simplified as opposed to analytic decision rules -have been reported in domains such as healthcare, military operational planning, and government policy making. We investigate the potential of a computational toolkit called "IMAGE" to improve decision-making by developing structural knowledge and increasing understanding of complex situations. IMAGE is tested within the context of a complex military convoy management task through (a) interactive simulations, and (b) visualization and knowledge representation capabilities. We assess the usefulness of two versions of IMAGE (desktop and immersive) compared to a baseline. Results suggest that the prosthesis helped analysts in making better decisions, but failed to increase their structural knowledge about the situation once the cognitive prosthesis is removed.

“…Indeed, devices such as the Oculus Rift 1 or the HTC Vive 2 provide roomscale VR experiences with hand-based interaction capabilities. Such setup tends to provide experience coming close to system such as CAVEs [Cruz-Neira et al 1992] but with a lower accessibility threshold. VR technologies have an important number of possible use cases such as gaming, data visualization, learning, ComputerAided Design (CAD), etc.…”

In a co-located collaborative virtual environment, multiple users share the same physical tracked space and the same virtual workspace. When the virtual workspace is larger than the real workspace, navigation interaction techniques must be deployed to let the users explore the entire virtual environment. When a user navigates in the virtual space while remaining static in the real space, his/her position in the physical workspace and in the virtual workspace are no longer the same. Thus, in the context where each user is immersed in the virtual environment with a Head-Mounted-Display, a user can still perceive where his/her collaborators are in the virtual environment but not where they are in real world. In this paper, we propose and compare three methods to warn users about the position of collaborators in the shared physical workspace to ensure a proper cohabitation and safety of the collaborators. The first one is based on a virtual grid shaped as a cylinder, the second one is based on a ghost representation of the user and the last one displays the physical safe-navigation space on the floor of the virtual environment. We conducted a user-study with two users wearing a Head-Mounted-Display in the context of a collaborative FirstPerson-Shooter game. Our three methods were compared with a condition where the physical tracked space was separated into two zones, one per user, to evaluate the impact of each condition on safety, displacement freedom and global satisfaction of users. Results suggest that the ghost avatar and the cylinder grid can be good alternatives to the separation of the tracked space.

When these two users wear a HMD, they can still perceive each other in the VE but no longer in the real workspace. In that case, we must avoid any possible physical collision between the two users.

“…A VR CAVE is a semi-immersive environment where images are projected on to three walls and the ceiling (Figure 2). A user wears 3D glasses to enable depth perception in the environment (Cruz-Neira et al, 1992). When the user moves in the CAVE, his or her head position is tracked in order to present the images in real-time and to provide the correct perspective (Rebelo et al 2010).…”

AbstractEase of entry and exit is important for creating a positive first impression of a car and to increase customer satisfaction. Several methods are used within vehicle development to optimise ease of entry and exit, including CAD reviews, benchmarking and buck trials.However, there is an industry trend towards digital methods to reduce the costs and time associated with developing physical prototypes. This paper reports on a study of entry strategy in three properties (buck, car, CAVE) in which inconsistencies were demonstrated by people entering a vehicle representation in the CAVE. In a second study industry practitioners rated the CAVE as worse than physical methods for identifying entry and exit issues, and having lower perceived validity and reliability. However, the resource issues associated with building bucks were recognised. Recommendations are made for developing the CAVE and for combinations of methods for use at different stages of a vehicle's development. Keywords: entry exit, automotive Highlights: Inconsistent entry strategies were observed in a CAVE virtual environment  The CAVE needs development to support design for ease of entry and exit  Representation of vehicular hard points is necessary for optimising entry and exit  Various combinations of methods are required at different stages of vehicle development 2
