This paper advocates the application of sensor fusion for the visualisation of social robotic behaviour. Experiments with the Virtual Reality Workbench integrate the key elements of Virtual Reality and robotics in a coherent and systematic manner. The deliberative focusing of attention and sensor fusion between vision systems and sonar sensors is implemented on autonomous mobile robots function...

Collaborative examination and use of shared documents often happens in a common physical space like in a tourist office. We developed a 3D immersive space to study collaboration on an information task in a virtual environment. In our paper, we present the qualitative results about cooperative work in the VirCA virtual environment. Our research is aiming to show that a 3D virtual environment can...

The use of virtual environments and on-line collaboration tools are rapidly growing. Educators and researchers are working together on designing virtual environments, for not only delivering the content, but also offering virtual facilities to practice newly learned skills, thus improving the effectiveness of the course. Immersive virtual environment designed for this study is tested within the...

A between-group experiment was carried out to assess whether two different presence questionnaires can distinguish between real and virtual experiences. One group of 10 subjects searched for a box in a real office environment. A second group of 10 subjects carried out the same task in a virtual environment simulating the same office. Immediately after their experience subjects were given two di...

A network security gateway protects the computers of a home or small office from Internet-based attacks by remote adversaries. It allows all the protected machines to share a single connection to the Internet and may allow secure access, via a VPN tunnel, into a remote corporate network. It may provide other services as well. Because its main job is security, it is critical to have high confide...

The Virtual Solar-Terrestrial Observatory (VSTO) is a distributed, scalable education and research environment for searching, integrating, and analyzing observational, experimental and model databases in fields of solar, solar-terrestrial and space physics. Our work on VSTO required us to create a formal, machine understandable representation for concepts, relations and attributes of physical q...
