Evoking Affordances in Virtual Environments via Sensory-Stimuli Substitution

David C. Gross, Kay M. Stanney, Lt. Joseph Cohn
2005 Presence - Teleoperators and Virtual Environments  
Virtual environments (VEs) similarly seek to afford specific utility to their users, whether it is for training, education, or entertainment, thus it seems natural to consider basing VE designs on affordances  ...  Artifacts in an environment afford to their observers utility and function directly through specific object characteristics (e.g., mediums, surfaces, substances).  ...  Sensory Substitution via Affordance-Based Designs The potential breakdowns in the realization of affordances in VEs can potentially be overcome by (a) correlating sensory stimuli to the experience represented  ...

Haptic, Virtual Interaction and Motor Imagery: Entertainment Tools and Psychophysiological Testing

Sara Invitto, Chiara Faggiano, Silvia Sammarco, Valerio De Luca, Lucio De Paolis
2016 Sensors  
In this work, the perception of affordances was analysed in terms of cognitive neuroscience during an interactive experience in a virtual reality environment.  ...  In other words, Gibson's affordances introduce the idea of the actor-environment mutuality: the actor and the environment make an inseparable pair.  ...  Acknowledgments: This work has been supported by EDOC@Work Project 3.0-Education and Work in Cloud. We thank Virginia Massari illustrator, who provided the design of the cup ( Figure 2 ).  ...

Extended Reality for the Clinical, Affective, and Social Neurosciences

Thomas D. Parsons, Andrea Gaggioli, Giuseppe Riva
2020 Brain Sciences  
Extended reality environments extend assessment and training platforms that balance experimental control with emotionally engaging background narratives aimed at extending the affective experience and  ...  Herein, we highlight the promise of extended reality platforms for greater ecological validity in the clinical, affective, and social neurosciences.  ...  The VR platforms provoke a sense of "presence" (feeling of being there) in participants and has potential for evoking affective arousal in affective neuroscience environments.  ...

Defining Virtual Reality: Dimensions Determining Telepresence

Jonathan Steuer
1992 Journal of Communication  
The defintion of virtual reality is based on concepts of "presence" and "telepresence," which refer to the sense of being in an environment, generated by natural or mediated means, respectively.  ...  Virtual reality (VR) is typically defined in terms of technological hardware.  ...  Each of these situations evokes, in some sense, a feeling of telepresence. A similar sense can be experienced via virtually any technology used in mediated communication.  ...

Another look at 'being there' experiences in digital media: Exploring connections of telepresence with mental imagery

Inma Rodríguez-Ardura, Francisco J. Martínez-López
2014 Computers in Human Behavior  
A review of major perspectives in this field provides justification of the important role mental imagery processes play in the phenomenon of telepresence.  ...  In line with this, we propose to extend existing approaches to mental imagery to reach the context of user experiences in digital media, and to theoretically connect telepresence with mental imagery.  ...  In the first case, telepresence-evoking content is used along with consumer knowledge and beliefs to construct mental models in and around the virtual environment.  ...

Toward Enhanced Teleoperation Through Embodiment

Alexander Toet, Irene A. Kuling, Bouke N. Krom, Jan B. F. van Erp
2020 Frontiers in Robotics and AI  
In accordance with the predictive encoding theory, none of the sensory modalities is critical in establishing ownership, and discrepancies in multisensory signals do not necessarily lead to loss of embodiment  ...  Numerous previous studies have shown that it is possible to induce embodiment over a wide range of virtual and real extracorporeal objects (including artificial limbs, avatars, and android robots) through  ...  in such mediated environments.  ...

Potential Mechanisms of Sensory Augmentation Systems on Human Balance Control

Kathleen H. Sienko, Rachael D. Seidler, Wendy J. Carender, Adam D. Goodworth, Susan L. Whitney, Robert J. Peterka
2018 Frontiers in Neurology  
The dominant hypothesis, which has not been supported by rigorous experimental evidence, posits that observed reductions in postural sway are due to sensory reweighting: feedback of body motion provides  ...  the CNS with a correlate to the inputs from its intact sensory channels (e.g., vision, proprioception), so individuals receiving sensory augmentation learn to increasingly depend on these intact systems  ...  Sensory restoration, substitution, and addition alter the available sensory information and are likely to have an impact on sensory integration via sensory reweighting.  ...

Virtual Reality for Emotion Elicitation – A Review [article]

Rukshani Somarathna, Tomasz Bednarz, Gelareh Mohammadi
2021 arXiv   pre-print
So, in response to the gap in the literature, this study intends to explore the possibility of using Virtual Reality (VR) as an active mechanism for emotion induction.  ...  Therefore, in the present review, we evaluated to what extent VR visual and audio-visual stimuli, games, and tasks, and 360-degree panoramas and videos can elicit emotions based on the current literature  ...  Virtual Environments (VE).  ...

Impact of 3-D Advertising on Product Knowledge, Brand Attitude, and Purchase Intention: The Mediating Role of Presence

Hairong Li, Terry Daugherty, Frank Biocca
2002 Journal of Advertising  
The conceptualization of a virtual experience has emerged because advancements in computer technology have led to a movement toward more multi-sensory online experiences.  ...  By creating compelling online virtual experiences, advertisers can potentially enhance the value of product information presented and engage consumers in an active user-controlled product experience.  ...  These new perceptual cues that guide a shopper's assessment of a product in a 3-D environment are what we call virtual affordances.  ...

Creating a sense of place with a deliberately constrained virtual environment

Phil Turner, Susan Turner, Luke Burrows
2013 International Journal of Cognitive Performance Support  
We report on the usefulness of an intentionally low fidelity virtual environment which relies on the metaphor of the 'tourist gaze' and the power of imagination to create a sense of place.  ...  In evaluation, participants reported experiencing a sense of place rather than a mere collection of images.  ...  Acknowledgements We thank the participants in this study for their time and the reviewers of the earlier version of this paper for their helpful comments.  ...

2020 Cerebral Cortex  
Interactions between individuals and the environment occur within the peri-personal space (PPS). The encoding of this space plastically adapts to bodily constraints and stimuli features.  ...  Here, we test this idea first via a visuo-tactile reaction time (RT) paradigm in augmented reality where participants are asked to respond as fast as possible to touch, as visual objects approach them.  ...  the environment and sensory history change.  ...
