Attention-based Level-Of-Detail (LOD) managers downgrade the quality of areas that are expected to go unno-ticed by an observer to economize on computational resources. The perceptibility of lowered visual fidelity is determined by the accuracy of the attention model that assigns quality levels. Most previous attention based LOD managers do not take into(More)
Successfully predicting visual attention can significantly improve many aspects of computer graphics: scene design, interactivity and rendering. Most previous attention models are mainly based on low-level image features, and fail to take into account high-level factors such as scene context, topology, or task. Low-level saliency has previously been(More)

This paper presents an experiment exploring gender differences in spatial navigation, memory performance and spatial awareness through a complex Virtual Environment (VE). The immersive simulation consisted of a radiosity-rendered space divided in four zones including a kitchen area, a dining area, an office area and a lounge area. The space was populated(More)
