Assessing the Relationship Between Type of Head Movement and Simulator Sickness Using an Immersive Virtual Reality Head Mounted Display: A Pilot Study

Individuals with autism spectrum disorder (ASD) regularly experience situations in which they need to give answers but do not know how to respond; for example, questions related to everyday life activities that are asked by strangers. Research geared at utilizing technology to mend social and communication impairments in children with autism is actively underway. Immersive virtual reality (VR) is a relatively recent technology that has the potential of being an effective therapeutic tool for developing various skills in autistic children. This paper presents an interactive scenario-based VR system developed to improve the communications skills of autistic children. The system utilizes speech recognition to provide natural interaction and role-play and turn-taking to evaluate and verify the effectiveness of the immersive environment on the social performance of autistic children. In experiments conducted, participants showed more improved performance with a computer augmented virtual environment (CAVE) than with a head mounted display (HMD) or a normal desktop. The results indicate that immersive VR could be more satisfactory and motivational than desktop for children with ASD.

Immersive Systems

A lot of professionals or hobbyists at home would like to create their own immersive virtual reality systems for cheap and taking little space. We offer two examples of such "home-made" systems using the cheapest hardware possible while maintaining a good level of immersion: the first system is based on a projector (VRKit-Wall) and cost around 1000$, while the second system is based on a head-mounted display (VRKit-HMD) and costs between 600� and 1000�. We also propose a standardization of those systems in order to enable simple application sharing. Finally, we describe a method to calibrate the stereoscopy of a NVIDIA 3D Vision system.

Maximum Duration

There are major concerns about the suitability of immersive virtual reality (VR) systems (i.e., head-mounted display; HMD) to be implemented in research and clinical settings, because of the presence of nausea, dizziness, disorientation, fatigue, and instability (i.e., VR induced symptoms and effects; VRISE). Research suggests that the duration of a VR session modulates the presence and intensity of VRISE, but there are no suggestions regarding the appropriate maximum duration of VR sessions. The implementation of high-end VR HMDs in conjunction with ergonomic VR software seems to mitigate the presence of VRISE substantially. However, a brief tool does not currently exist to appraise and report both the quality of software features and VRISE intensity quantitatively. The Virtual Reality Neuroscience Questionnaire (VRNQ) was developed to assess the quality of VR software in terms of user experience, game mechanics, in-game assistance, and VRISE. Forty participants aged between 28 and 43 years were recruited (18 gamers and 22 non-gamers) for the study. They participated in 3 different VR sessions until they felt weary or discomfort and subsequently filled in the VRNQ. Our results demonstrated that VRNQ is a valid tool for assessing VR software as it has good convergent, discriminant, and construct validity. The maximum duration of VR sessions should be between 55 and 70 min when the VR software meets or exceeds the parsimonious cut-offs of the VRNQ and the users are familiarized with the VR system. Also, the gaming experience does not seem to affect how long VR sessions should last. Also, while the quality of VR software substantially modulates the maximum duration of VR sessions, age and education do not. Finally, deeper immersion, better quality of graphics and sound, and more helpful in-game instructions and prompts were found to reduce VRISE intensity. The VRNQ facilitates the brief assessment and reporting of the quality of VR software features and/or the intensity of VRISE, while its minimum and parsimonious cut-offs may appraise the suitability of VR software for implementation in research and clinical settings. The findings of this study contribute to the establishment of rigorous VR methods that are crucial for the viability of immersive VR as a research and clinical tool in cognitive neuroscience and neuropsychology.

Virtual reality is becoming increasingly popular in today’s society. With this proliferation it becomes even more important to study the effects such environments may have on one’s perception of reality. Two pilot studies were run in order to provide insight into the relationship between time perception and flow in a virtual environment. In Experiment 1 participants played a music-oriented virtual game for 2 minutes. In Experiment 2 participants played a space-shooter virtual game for 5 minutes. Duration Judgment Ratio (DJR) and Flow State Scale (FSS-2) measures were taken and compared to one another. Though a relationship between DJR and Flow was not found in each experiment individually, insights gained from the comparison of the two experiments may provide additional understandings. The results of this pilot study could aid researchers in developing objective ways to measure components of flow especially with respect to virtual environments. Additional insights and applications are discussed.

Simulator Sickness Questionnaire

Cybersickness continues to become a negative consequence that degrades the interface for users of virtual worlds created for Virtual Reality (VR) users. There are various abnormalities that might cause quantifiable changes in body awareness when donning an Head Mounted Display (HMD) in a Virtual Environment (VE). VR headsets do provide VE that matches the actual world and allows users to have a range of experiences. Motion sickness and simulation sickness performance gives self-report assessments of cybersickness with VEs. In this study a simulator sickness questionnaire is being used to measure the aftereffects of the virtual environment. This research aims to answer if Immersive VR induce cybersickness and impact equilibrium coordination. The present research is formed as a cross-sectional observational analysis. According to the selection criteria, a total of 40 subjects would be recruited from AVBRH, Sawangi Meghe for the research. With intervention being used the experiment lasted 6 months. Simulator sickness questionnaire is used to evaluate the after-effects of a virtual environment. It holds a single period for measuring motion sickness and evaluation of equilibrium tests were done twice at exit and after 10 mins. Virtual reality being used in video games is still in its development. Integrating gameplay action into the VR experience will necessitate a significant amount of study and development. The study has evaluated if Immersive VR induce cybersickness and impact equilibrium coordination. To measure cybersickness, numerous scales have been developed. The essence of cybersickness has been revealed owing to work on motion sickness in a simulated system.

Architectural Spaces

To design architectural spaces that not only respond to the basic needs of users, but also seek their emotional well-being, it is necessary for the architecture students to have a special sensitivity and be aware of the different sensations that their designs should and can evoke. To achieve this competence without exploring real spaces, Immersive Virtual Reality technology offers an important contribution to the field of architecture. The purpose of this research is to determine if the sensations perceived in virtual architectural spaces by students are similar to the real ones and to determine the characteristics of this technology that allow a better perception of sensations. Six architectural modules were designed to be walked through and experienced at real scale using a Head Mounted Display by 22 students of the first and fifth year of studies of Architecture career in Peru. An ad-hoc questionnaire allowed to know the perceived sensations and the benefits of the tool. The results obtained showed that the perception of sensations of the fifth year students is a little closer to those expressed by a group of seven experts compared to that of the first year students and that the students consider the characteristics of accessibility, real scale of the space and the possibility of going through and looking at the space in all directions are those that have given more realism to the experience and therefore better perception of the space, while the characteristics of natural light and shadows, construction materials and external environment have been less valued in the realism of the experience. It is concluded that the sensory experimentation in architectural spaces modelled realistically in virtual environments allows the perception of sensations very similar to those that the architect seeks to convey initially.
