This paper describes a study of a three-dimensional virtual prototype intended for usability testing and concept validation over the internet. A virtual reality modeling language (VRML)-model of a fictive mobile phone concept with simulated interaction functionality was tested for usability following two approaches. The first group performed a traditional task-based usability test, the other pe...

For testing the programs students were screened for their space perception, and then performed paper tests. One group was permitted to practice using the virtual reality programs; the other used only traditional tutorial methods. A second paper test was then performed. The evaluation of the two tests showed that the possibility of using the virtual reality programs increased the space perceptio...

This poster describes informal testing of a wearable augmented reality system as a method to guide school age children to specific outdoor locations where learning content might be situated. Speed and accuracy of students in finding locations is evaluated comparing paper maps with guided and unguided wearable augmented reality.

The goal of this paper is to survey the main issues with the ergonomic evaluation of MRS (Mixed Reality Systems) and to stimulate discussions for future research. A first point concerns definitions and specificities of MRS within the « reality / virtuality » continuum, and the incorporation of user issues. Another point concerns the combinatory character of the ergonomic knowledge to be applied...

It has been shown that an illusion of ownership over an artificial limb or even an entire body can be induced in people through multisensory stimulation, providing evidence that the surrogate body is the person’s actual body. Such body ownership illusions (BOIs) have been shown to occur with virtual bodies, mannequins, and humanoid robots. In this study, we show the possibility of eliciting a f...

This paper presents an exploratory study that created a Virtual Reality Environment (VRE) to stimulate motivation and creativity in imaginative writing at primary school level. The main aim of the study was to investigate if an interactive, semi-immersive Virtual Reality (VR) world could increase motivation and stimulate pupils’ imagination in the context of a writing task that is part of norma...
