Empirical evidence of the benefits of immersion is an important goal for the virtual environment (VE) community. Direct comparison of immersive systems and non-immersive systems is insufficient because differences between such systems may be due not only to the level of immersion, but also to other factors, such as the input devices and interaction techniques used. In this paper, a study is presented that separates the effects of level of immersion and 3D interaction technique for a six-degree-of-freedom manipulation task. In the study, two components of immersion - stereoscopy and field of regard - were varied and three 3D interaction techniques - HOMER, Go-Go, and DO-IT (a new keyboard- and mouse-based technique) - were tested. The results of the experiment show that the interaction technique had a significant effect on object manipulation time, while the two components of immersion did not. The implications of these results are discussed for VE application developers. Copyright 2006 ACM.
Collaborative computer systems are in widespread use, but relatively little is known about how to evaluate their usability. My research focuses on extending usability inspection techniques for evaluating collaborative...

In 1969 Herbert Simon put forward the idea that: "in an information rich world, the scarce resource is [human] attention." Today this would seem to be increasingly true. This talk will suggest that a number of the important challenges for modern interactive computing - goals we describe as "invisible", "ambient", "pervasive", "ubiquitous" or even "calm" - are fruitfully considered in these terms. I will suggest that traction can be gained by focusing on optimization of human attention as a principle. Illustrations of the value of using this perspective to view the research will be drawn from our ongoing "Managing human Attention" project.
Training in virtual reality (VR) offers advantages such as a safe learning environment, good scalability, and cost saving. However, state-of-the-art simulations are limited in faithfully conveying real-world physical ...
