“…The utility of vection research lies mainly in the understanding how vection is elicited and which sensory systems contribute to its perception, and subsequently using this information to 1) enhance the fidelity (e.g., immersiveness or presence) of virtual driving or flight simulators and 2) reduce the risk of eliciting motion sickness (MS). The fidelity of simulators is often assessed via measures of presence (e.g., Brackney & Priode, 2017), and previous research has shown a positive correlation between vection and spatial presence when participants viewed naturalistic moving stimuli (Riecke et al, 2005a).…”

Vection is classically defined as the illusory perception of self-motion induced via visual stimuli. The utility of vection research lies in its potential to enhance simulation fidelity, as measured through presence, and reduce the probability that motion sickness symptoms occur. Studies have shown a multimodal interaction of various sensory systems in facilitating vection and the utility of co-stimulating some of these sensory systems along with the presentation of visual stimuli have been reviewed. However, a review on the use of tactile stimulation in vection research appears to be missing from literature. The purpose of this review is to evaluate the current methodologies, and outcomes, of tactile stimulation in vection research. We searched for articles through EBSCOHost, Scopus and Web of Science. Studies were included only if they detailed an experiment on the effect of tactile stimulation on vection. Twenty-four studies were obtained and distilled in tabular form. Eighteen studies contained sufficient information to be included in a meta-analysis. We identified that tactile stimulation has mostly been applied in the form of vibrational stimulation to the feet. Furthermore, tactile stimulation is most effective when it is presented in a temporally congruent manner to other sensory cues whereas tactile stimulation as a unisensory stimulus does not appear to be effective in eliciting vection. We discuss the need for more qualitative research to reduce methodological inhomogeneities and recommend future research in tactile-mediated vection to investigate stimulation to the torso and investigate the use of forces as a tactile stimulus.

Vection is classically defined as the illusory perception of self-motion induced via visual stimuli. The utility of vection research lies in its potential to enhance simulation fidelity as measured through presence and reduce the probability that motion sickness symptoms occur through the identification of differences and similarities in physiological responses to vection and motion sickness. Recent studies have shown a multimodal interaction of various sensory systems in facilitating vection. Moreover, the utility of co-stimulating some of these sensory systems along with the presentation of visual stimuli have been reviewed. However, a review on the tactile mediation of vection appears to be missing from literature. The purpose of this review is to evaluate the current methodologies, and utility of, tactile stimulation in vection research. We searched for articles through EBSCOHost, Scopus and Web of Science. Only studies were included wherein an experiment on the effect of tactile stimulation on human self-motion perception was detailed. Twenty-three studies were obtained and distilled in tabular form. The studies reviewed presented a strong variability in the a-priori definition of vection, methodological inhomogeneity, varying approaches to the assessment of subjective vection measures and a lack of objective measures. We discuss the need for more qualitative research to reduce methodological inhomogenities, recommend future research in tactile-mediated vection to investigate stimulation to the torso, and suggest further investigation into the utility of concurrently presenting different forms of tactile stimulation.

“…We aim to answer the above research questions (representing independent variables) by asking users to judge on a number of factors (dependent variables) that can potentially affect them. Subjective ratings and measurements represent trustable indications for immersive VR systems due to the high user involvement and observable effects those systems provide [66]. The ratings are related to display perceived lighting and human sensations in terms of visual realism, presence, emotions, and depth impression.…”

“…A number of authors propose the use of image-quality metrics and subjective rating to assess visual realism, image quality and naturalness. Brackney et al [66] indicate interaction, control and motion, as relevant elements that should be part of a realism questionnaire and proposes the use of the INASCL simulator [67], which contemplates 11 criteria including fidelity, defined as true-to-life experience. It divides realism as physical, conceptual and psychological, with all those aspects to contribute to engagement and to be included when assessing realism of VR simulations.…”

Virtual Reality headsets have evolved to include unprecedented display quality. Meantime, they have become light-weight, wireless and low-cost, which has opened to new applications and a much wider audience. Photo-based omnidirectional imaging has also developed, becoming directly exploitable for VR, with their combination proven suitable for: remote visits and realistic scene reconstruction, operator's training and control panels, surveillance and e-tourism. There is however a limited amount of scientific work assessing VR experience and user's performance in photo-based environment representations. This paper focuses on assessing the effect of photographic realism in VR when observing real places through a VR headset, for two different pixel-densities of the display, environment types and familiarity levels. Our comparison relies on the observation of static three-dimensional and omnidirectional photorealistic views of environments. The aim is to gain an insight about how photographic texture can affect perceived realness, sense of presence and provoked emotions, as well as perception of image-lighting and actual space dimension (true-dimension). Two user studies are conducted based on subjective rating and measurements given by users to a number of display and human factors. The display pixel-density affected the perceived image-lighting and prevailed over better lighting specs. The environment illumination and distance to objects generally played a stronger role than display. The environment affected the perceived image-lighting, spatial presence, depth impression and specific emotions. Distances to a set of objects were generally accurately estimated. Place familiarity enhanced perceived realism and presence. They confirmed some previous studies, but also introduced new elements.INDEX TERMS Extended reality, head mounted displays, photorealism, visualization.
