This paper presents validation of the VR Simulation Realism Scale on a Polish sample. The scale enables a self-report measurement of perceived realism of a virtual environment in four main aspects of such realism–scene realism, audience behavior realism, audience appearance realism and sound realism. However, since the development of the original s...

Studies from English-speaking countries show that sex toy use is common in various populations and often associated with sexual well-being. Empirical data on sex toy use and perceived effects in other countries is still missing. Based on the Positive Sexuality framework and the Positive Technology framework, this study documented the prevalence of...

In his seminal book “Love and Sex with Robots”, David Levy (Love and sex with robots: the evolution of human–robot relations, Harper, New York, 2007) predicted that intimate human–robot relationships will be normalized by 2050. So far, only a very small number of early adopters of love and sex robots has experienced these kinds of relationships. Th...

Although visual attention cues are of particular importance for driving simulation tasks, research on the relationship of visual attention and simulator sickness is scarce. This exploratory study is aimed at investigating this relation with a laboratory study in a fixed-based driving simulator (N = 36). No correlation between visual attention and s...

Good public speaking skills are essential in many professions as well as everyday life, but speech anxiety is a common problem. While it is established that public speaking training in virtual reality (VR) is effective, comprehensive studies on the underlying factors that contribute to this success are rare. The “quality evaluation of user-system i...

Selfies (self-portrait photographs often taken with a camera phone) are popularly used for self-presentation in social media like Facebook and Instagram. These modern user-generated self-portraits have the potential to draw a more versatile picture of the genders instead of reproducing traditional gender stereotypes often presented in mainstream me...

Virtual reality exposure therapy (VRET) applications use high levels of fidelity in order to produce high levels of presence and thereby elicit an emotional response for the user (like fear for phobia treatment). State of research shows mixed results for the correlation between anxiety and presence in virtual reality exposure, with differing result...

Realistic models in virtual reality training applications are considered to positively influence presence and performance. The experimental study presented, analyzed the effect of simulation fidelity (static vs. animated audience) on presence as a prerequisite for performance in a prototype virtual fear of public speaking application with a sample...

Full-text available
Presentation skills that involve public speaking are an asset that many recognize to be important for their careers or during their study. One way to learn how to maintain eye contact and address clearly as a speaker is to use virtual audiences (VA) that simulate the reactions of a live public. A mixed-methods exploratory study has been conducted t...

Full-text available
Virtual training applications with high levels of immersion or fidelity (for example for social phobia treatment) produce high levels of presence and therefore belong to the most successful Virtual Reality developments. Whereas display and interaction fidelity (as sub-dimensions of immersion) and their influence on presence are well researched, rea...

Speech anxiety (SA) training may help subjects improve their skills on keeping audiences interested in the speech and on managing calm or restless audiences. Attention and lack of attention during speeches are displayed through several nonverbal cues. Such and other nonverbal behaviors can also spread throughout a group and engage whole audiences....

Virtual reality (VR) applications for fear of public speaking pose several design challenges with regard to the adaptability of the scenarios to the training/treatment requirements of each person. The present study focuses on three major aspects identified in literature that would help customize the virtual audience for fear of public speaking appl...

Sound is an important part of an immersive virtual environment, contributing to immersion, presence, and user performance. The experimental study presented analyzed the effect of spatial-sound vs. no-sound display on presence experienced in a 3D virtual scene. Results indicate a medium to strong effect of spatial sound, leading to higher levels of...
