Practice Trial

Three frames of reference (full exocentric, full egocentric and tethered) were contrasted in three experiments to measure performance of four different scientific visualization subtasks: search, travel, local judgment support and global judgment support. Participants were instructed to locate and follow a designated path through simple virtual environments and to answer simple questions about that environment. Each subject completed 5 trials in every frame of reference condition (exocentric, egocentric and tethered) with the subject's first trial serving as a practice trial. The results revealed that frames of reference that utilize egocentric or tethered viewpoints support better travel performance, especially when nearing the target. However the exocentric frame of reference supported better performance in the search subtasks and the local and global judgment subtasks.

Measure Sense

Abstract. The sense of presence is the feeling of being there in a virtual environment. A three-component self report scale to measure sense of presence is described, the components being sense of spatial presence, involvement, and realness. This three-component structure was developed in a survey study with players of 3D games (N = 246) and replicated in a second survey study (N = 296); studies using the scale for measuring the effects of interaction on presence provide evidence for validity. The findings are explained by the Potential Action Coding Theory of presence, which assumes that presence develops from mental model building and suppression of the real environment.

Abstract. Computers have long been seen as possible tools to foster creativity in children. In this respect, virtual environments present an interesting potential to support idea generation but also to steer it in relevant directions. A total of 96 school-aged children completed a standard divergent thinking task while being exposed to one of three virtual environments: a replica of the headmistress’s office, a replica of their schoolyard, and a dreamlike environment. Results showed that participants produced more original ideas in the dreamlike and playful environments than in the headmistress’s office environment. Additionally, the contents of the environment influenced the selective exploration of idea categories. We discuss these results in terms of two combined processes: explicit references to sources of inspiration in the environment, and the implicit priming of specific idea categories.
