“…Section 2): a guide had to give information through the virtual environment to another user whilst the latter was immersed in the VE. Several participants of the contest [3,16] proposed that the guide could simultaneously have a world in miniature representation of the VE and the viewpoint of the other user. They suggested that the guide could also add navigation aids by interacting with the world in miniature representation.…”

Figure 1: Left: Outside view of a launcher. Middle: In the little black cylinder of this launcher, an operator is working in virtual reality with an HMD. The red virtual object represents his avatar. Right: At the same time, remotely in the virtual environment, a second operator is using Pano to interact with the first operator. Thanks to Pano, he can see the entire interior of the launcher. ABSTRACTVirtual Reality experiments have enabled immersed users to perform virtual tasks in a Virtual Environment (VE). Before beginning a task, however, users must locate and select the different objects they will need in the VE. This first step is important and affects global performance in the virtual task. If a user takes too long to locate and select an object, the duration of the task is increased. Moreover, both the comfort and global efficiency of users deteriorate as search and selection time increase.We have developed Pano, a technique which reduces this time by increasing the users natural field of view. More precisely, we provide a 360 panoramic virtual image which is displayed on a specific window, called the PanoWindow. Thanks to the PanoWindow, users can perceive and interact with the part of the Virtual Environment (VE) that is behind them without any additional head or body movement. In this paper, we present two user studies with 30 and 21 participants in different VEs. For the first study, participants were invited to perform object-finding tasks with and without Pano. The second study involved position-estimating tasks in order to know if the PanoWindow image enables users to build an accurate representation of the environment. First, the results show that Pano both reduces task duration and improves user comfort. Second, they demonstrate that good object-localization accuracy can be achieved using Pano.

“…also provides opportunities for users to express their actions and activities to others. The examples in Figure 2 and [1,22] illustrate the approach of using some simple visual metaphors for a mutual awareness and also a collaborative exploration without using verbal communication. A user can also use some colorful signals to inform others of his/her current states while navigating together (e.g., orange signal for "waiting", red for "stopping", green for "going").…”

In the domain of Collaborative Virtual Environments (CVEs), many virtual worlds, frameworks and techniques are built based on a specific and direct purpose. There is not a general and still good and efficient enough solution for all the collaborative systems. Depending on the purpose of the collaborative work, the techniques of interaction and of manipulation change from one application to another. Despite this difference between interaction techniques, they always benefit greatly from awareness features that help in explicating implicit knowledge related to one's own and others' working activities as well as to virtual workspace. In addition, people in CVEs also use communication channels to negotiate shared understandings of task goals, of task decomposition and of task progress. Therefore, awareness and communication are usually considered as "instruments" to complete collaborative tasks in the environment. However, few research work have been devoted to improving the awareness and the communication channels in CVEs for a better collaboration between users. In this paper, we will study the importance of awareness and communication in collaborative virtual environments. We will investigate different kinds of awareness which need to be carefully designed. We will also discuss different communication means and how to cope with this diversity, so we can benefit from the availability of different peripheral devices and can find an effective communication means to work together. Finally, we will make some propositions to overcome these actual limitations of CVEs.achieved, the performing step takes place while the communication and the awareness steps still go on.In the collaborative working process, the two important steps including coordination and performing, will highly benefit from awareness features that help to represent implicit knowledge related to one's own or others' working activities. In addition, people in CVEs also use communication channels to negotiate shared understandings of task goal, of task decomposition and of task progress. Therefore, awareness and communication are usually considered as "instruments" to complete collaborative tasks in an environment.In this paper, we will study the importance of awareness and communication in CVEs, and will investigate different kinds of awareness which need to be carefully designed in collaborative systems. Furthermore, we will discuss different communication means and how to cope with this diversity, so we can benefit from the availability of different peripheral devices and can find an effective communication means to work together.The remainder of this paper is structured as follows. The next section describes in more detail several kinds of awareness, followed by a small discussion on how to design a CVE for improving awareness. Different means of communication are briefly presented in the third section. The paper concludes with a discussion on the actual limitations of existing awareness and communication work and some suggestions of different aspects t...

“…We share this objective with the organizers of the 3DUI Contest 2012 and its participants. As navigation aids, some techniques had been proposed such as "anchors" and a string of blue arrows that connects them or directional arrows [2] [34], point light sources [10] or light signal or beacons [35][34] [43].…”

The feeling of presence is essential for efficient interaction within Virtual Environments (VEs). When a user is fully immersed within a VE through a large immersive display system, his/her feeling of presence can be altered because of disturbing interactions with his/her physical environment, such as collision with hardware parts of the system or loss of tracking. This alteration can be avoided by taking into account the physical features of the user as well as those of the system hardware and embedding them in the VE. Moreover, the 3D abstract representation of these physical features can also be useful for collaboration between distant users because they can make a user aware of the physical limitations of the others he/she is collaborating with. In this paper we present how we use the
