The ambiance in virtual environments is affected by the loss of multimodal information. For many purposes, the affective qualities of a virtual environment require special attention in the modeling process. In order to construct the right ambiance it can be beneficial to engineer the affective appraisal of the virtual environment. However, a userpsilas assessment of the affective qualities of a (virtual)...
We review some recent techniques for 3D tracking and occlusion handling for computer vision-based augmented reality. We discuss what their limits for real applications are, and why object recognition techniques are certainly the key to further improvements.
This paper presents the results of an experimental study on designing for self-efficacy in a game based driving simulator. Self-efficacy refers to how peoplepsilas beliefs in their capabilities affect their actions. The results show that the design of the feedback system can be used to increase self-efficacy measures thus affecting performance in a driving simulator environment. Self-efficacy has...
Advances in Internet connections speeds and computer hardware means that web content has grown richer and more interactive for users. One such area is Web3D which has seen the emergence of ISO standard technologies such as VRML (Virtual Reality Modeling Language) and its XML-based (eXtensible Markup Language) successor X3D(eXtensible 3D). X3D, in particular, presents opportunities for further integration...
The art of computer-based game production is an aspiring goal and a challenging task. It involves many different activities, expertise and skills into many different areas such as: game theory, programming skills, multimedia, 2D/3D graphics and animation, sound engineering, story writing, project design and management, physics, logic design, interface programming, artificial intelligence (AI) and...
The research presented in this paper aims at developing and validating a predictive tool of individual exposure to solar Ultra-Violet (UV). UV exposure depends on ambient irradiation level and individual factors related to activity (position to the sun, clothing, duration of exposure, and other forms of sun protection). We predict exposure levels of body parts on basis of ambient irradiation levels...
