Motivation â€“Several factors such as the kind of display technology and the level of user interaction have been found to affect presence (e.g. and IJsselsteijn et al and 2000). Generally and it had been concluded that the more immersive types of display result in higher levels of presence. However and studies comparing the effect of display technology on presence are mostly based on rendering the same content across different displays. Previous studies have typically not attempted to optimize the content for each display type individually. Furthermore and it has not been considered before that some viewers may not benefit as much as others from higher levels of technology. Research approach First and we investigate the relationships between perceived presence and some human factors and including stereoscopic ability and depth impression and and personality. We describe this experiment here in some detail. Second and we focus on the potential maximum presence that can be obtained for specific devices and for example and by manipulating the size and perspective and viewing distance. Third and we will investigate how monocular depth cues can be used to maximize presence for different display types. Finally and we will look specifically at how presence can be maximized on small hand-held devices and for example by incorporating compensation for display movement. In all our experiments we will focus on public speaking and person-to-avatar communication. Presence is measured in three different ways: 1) through questionnaires and 2) behaviourally and and 3) physiologically. Originality/Value â€“ Having a better understanding of the relation between human factors and feelings of presence may facilitate the selection of people that are most likely to benefit from virtual reality applications such as virtual reality exposure therapy (e.g. Krijn et al and 2004). A better understanding of how presence can be optimized on different displays and may also lead to the possibility to use less complex display types (as compared to HMDâ€™s or CAVEâ€™s) to create virtual reality consumer applications. It also opens the possibility to tailor the virtual reality display to the individual and optimizing presence.
