“…An underestimation of distances in virtual environments has been reported, but this effect seems to disappear when rendering and level of detail are of sufficient quality (Loyola, 2017; Mohler, Creem-Regehr, Thompson, & Bülthoff, 2010). Because we are interested in the effects of manipulated social cues on perceived IPD, the absolute level of the estimates, even if distorted in VR, is rather irrelevant as long as the direction and the slope of the effects remain unaffected by the virtual environment, which seems likely in the present experiments (for a discussion, see von Castell, Hecht, & Oberfeld, 2018).…”

In this study, we examined the impact of psychopathy on approach-avoidance reactions and interpersonal distance (IPD) in response to social cues. We selected a student sample and measured psychopathy via self-report. Participants were immersed in a virtual environment in which a virtual person displayed either angry or happy facial expressions. In the first experiment, participants had to walk toward the virtual person until a comfortable IPD had been reached. In the second experiment, participants had to push or pull a joystick in response to the facial expression of the virtual person. Our results suggest that psychopathy does not change average IPD but does impair its regulation. That is, the facial expression of the avatar no longer modulated IPD in participants with psychopathic traits to the extent that it did in participants with fewer psychopathic traits. The speed of the approach and avoidance reactions is altered in psychopathy when confronted with social cues.

“…Many studies regarding the perception of visual extent in virtual environments have reported a pronounced underestimation of stereoscopically presented spatial extent as compared to estimates of spatial extent in real environments, in particular, but not exclusively [ 25 , 43 ], for estimated depth (e.g., [ 43 – 50 ]; for a review see [ 51 ]). Such pictorial displays do suffer from sagittal foreshortening, in particular if the pictorial space is empty (see, e.g., [ 52 , 53 ]) and no feedback is provided (e.g., [ 54 , 55 ]; but see [ 56 ]). In line with these findings, we also observed a consistent underestimation of the presented spatial extent for both the width (cf.…”

Bright paint makes interior-space surfaces appear farther away

Previous studies have reported that bright ceilings appear higher than dark ceilings, irrespective of the other colorimetric properties of the ceiling color (hue, saturation) and irrespective of the luminance of the remaining room surfaces (walls, floor). In the present study, we expand these findings to width and depth estimates. We presented stereoscopic full-scale room simulations on a head-mounted display and varied the luminance of the side walls, rear wall, and ceiling independently of each other. Participants judged the width and depth of the simulated rooms. Our results show that the perceived spatial layout of a given room is significantly influenced by the luminance of the direct bounding surfaces (e.g., the side walls when judging perceived width) but less affected by the luminance of the other surfaces. In the discussion, we provide an overall picture of effects of surface luminance on the perceived layout of interior spaces and discuss the conclusions in the context of existing interior-design guidelines.

“…Owing to common knowledge and a vast literature on stereoscopic representation on HMDs, it is clear that factors such as IPD (interpupillary distance) and virtual environment scale can largely affect distance perception [Nguyen et al 2011] and the user's sense of immersion. Regarding distance perception in HMDs with tracking systems, non-pictorial depth cues affecting immersiveness derive either from motion (motion parallax), the oculomotor [Loyola 2017]. Owing to its importance for executing interactive tasks, distance perception in HMDs did prove its crucial role and how this affected application development and interaction models, especially regarding correct distance judgment.…”

Virtual Museums (VMs) and their audiences have always been studied as separated worlds. Recently the importance of cross-methodological studies has been accepted by the academic sector for their usefulness in the process of assessing the impact of such VMs. Hedonic aspects, such as emotions, senses, perception, and environmental atmosphere rather than technicalities, like usability and affordance, have indeed played a precise and crucial role in the meaning-making of the world around us. This contribution will highlight the need for a collaborative sharing of ideas among designers and developers, creators and technicians, in order to reach sensory immersion and emotional involvement in VMs that will translate into enhanced participation and the predisposition to assimilate and memorize cultural contents. It has been stated that “a virtual museum is a digital entity.” As such, it is inevitably based on technology, on its user interface (UI), on the visualization solutions it employs, and on its usability and ability to interact with the end user in order to transfer a certain message. VMs are designed to complement, enhance, or augment the ordinary museum experience through contextualization, narration, personalization, interactivity and richness of content. This contribution originates not only from the lessons learned in twenty years of research by CNR ITABC, but it also moves one step further in the direction of exchanged experiences and good practices between the humanistic and the technological sectors, therefore contributing to the promotion of lifelong learning in Virtual Museums.
