Our work investigates whether distances are still compressed in a large screen display immersive virtual environment, where participants are able to see their own body surrounded by the virtual environment. We conducted our experiment in both the real world using a real room and the large screen display immersive virtual environment using a 3D model of the real room. Our results showed a significant underestimation of verbal reports of egocentric distances in the large screen display immersive virtual environment, while the distance judgments of the real world were closer to veridical. Moreover, we observed a significant effect of distances in both environments. In the real world closer distances were slightly underestimated, while further distances were slightly overestimated. In contrast to the real world in the virtual environment participants overestimated closer distances (up to 2.5m) and underestimated distances that were further than 3m. A possible reason for this effect of distances in the virtual environment may be that participants perceived stereo cues differently when the target was projected on the floor versus on the front of the large screen.","PeriodicalId":89458,"journal":{"name":"Proceedings APGV : ...

A wide variety of approaches for resizing exist: sophisticated \"content-aware\" (or retargeting) approaches are built on the assumption that carefully chosen distortions are preferable to the naïve approach of uniformly stretching the image. However, there is little codified understanding of how distortions of the image, including uniform stretching or more complex warps introduced by retargeting, are perceived. In this paper, we describe experiments that explore the perception of image stretching, to establish the baseline for assessing more complex resizing methods, as well as to establish the methodology. In a series of experiments, we show that the perception of stretching is a complex phenomenon depending on a myriad of factors including the amount of distortion, the image content, the viewer's cultural background, and the observation time. We provide a methodology for creating images that avoid unfair cues to stretching and explore issues in using online worker communities for studies. We show that even small stretches can be detected in some cases. These findings have ramifications for the design and evaluation of image retargeting, and suggest that a more thorough study of distortion perception is necessary.","PeriodicalId":89458,"journal":{"name":"Proceedings APGV : ...

Memory of spaces is an imperfect reflection of the cognitive activity (awareness states) that underlies performance in such environments. Furthermore, performance on these tasks may also be influenced by the context of the environment. This research investigates the effect of stereo viewing on object recognition after exposure to an immersive VE, in terms of both scene context and associated awareness states. The immersive simulation consisted of a radiosity-rendered room that was either populated by objects consistent with an office setting or by primitive objects located in similar positions. The simulation was displayed on a stereo head-tracked Head Mounted Display. Twenty-four participants across two visual conditions of varying depth cues (absence vs presence of stereo cues) were exposed to the VE and completed an object-based memory recognition task. Participants also reported one of four states of awareness following each recognition response which reflected whether visual mental imagery was induced during retrieval. Results revealed better memory of objects that were consistent with the environment context and associated with vivid memorial experiences when the space was viewed in stereo.","PeriodicalId":89458,"journal":{"name":"Proceedings APGV : ...
