Cue Exposure Treatment

Cue exposure treatment (CET) consists of controlled and repeated exposure to drug-related stimuli in order to reduce cue-reactivity. Virtual reality (VR) has proved to be a promising tool for exposition. However, identifying the variables that can modulate the efficacy of this technique is essential for selecting the most appropriate exposure modality. The aim of this study was to determine the relation between several individual variables and self-reported craving in smokers exposed to VR environments. Forty-six smokers were exposed to seven complex virtual environments that reproduce typical situations in which people smoke. Self-reported craving was selected as the criterion variable and three types of variables were selected as the predictor variables: related to nicotine dependence, related to anxiety and impulsivity, and related to the sense of presence in the virtual environments. Sense of presence was the only predictor of self-reported craving in all the experimental virtual environments. Nicotine dependence variables added predictive power to the model only in the virtual breakfast at home. No relation was found between anxiety or impulsivity and self-reported craving. Virtual reality technology can be very helpful for improving CET for substance use disorders. However, the use of virtual environments would make sense only insofar as the sense of presence was high. Otherwise, the effectiveness of exposure might be affected.

Virtual Reality Exposure

This study is an examination of the effect of computer-generated virtual reality graded exposure on the physiological and psychological responses of performing musicians. Eight university saxophone majors, five men and three women, participated in twelve 15- to 20-minute weekly practice sessions during which they were immersed in one of four different virtual environments designed to elicit various anxiety levels. Baseline heart rates and subjective measurements were taken prior to immersion and continued throughout the exposure period. In addition, heart rate and subjective measurements were recorded for three live performances given by each subject before beginning the virtual reality exposure and after completion of the sixth and the twelfth exposure sessions. Findings indicated that the virtual environments did elicit a sense of presence and may have provided the means for desensitization. Heart-rate readings and psychological indications of anxiety did not always correspond.

This work focus on the study of solutions that using video 360 and virtual reality that allow children’s and older people that are away of their family environments for various reasons to be able to feel they are participating at family or school events. The solutions proposed should deliver a strong sense of presence to the users and the interface must be friendly. The validation will be made by user observation and inquiries.

Interactive Experience

As a new medium in modern education, virtual reality technology has stimulated the changes of pedagogical practice and added further opportunities for experiential learning. The immersive and interactive experience of VR fits seemingly well with practical subjects such as Creative Design. Design-related courses in secondary education usually appeal to the students with their practical elements, which also help in developing a student's creative and cognitive ability. The dual coding learning theory states that the learning process can be improved by using the symmetrical visual and language systems of the left and right hemispheres. This paper presents a novel teaching framework that combines classroom learning with VR technology. We devise the course structure based on Bloom’s Taxonomy and fill in knowledge and skills related to 3D Design. In collaboration with a local school, we implemented and delivered the proposed course to a group of students. After the course, we use questionnaires and interviews to collect and analyze the attendees’ feedback. The results show that the interactive experience in VR coincides better with the students’ perception of 3D conceptual design. The teaching methods are also well-received by them. Based on the findings, we suggest that immersive VR technology is a promising tool for developing practical courses such as product design and development.

Avoidance Responses

Behavioral therapy combined with a virtual reality exposure (VRE) component can be useful for the treatment of fears and phobias. This study aimed to: (a) describe and evaluate a behavioral therapy procedure amplified by VRE for the treatment of fear of height and (b) record sense of presence and cybersickness during exposure to assess the Virtua Therapy simulator. The procedure consisted of: an initial session; six therapy sessions, which included graduate exposure, prevention of escape-avoidance responses, and functional analyses of behaviors; two follow-up sessions. Sense of presence and cybersickness were recorded. The intervention decreased the participants’ levels of anxiety and the frequency of avoidance of situations involving heights in the virtual environment, and they reported decreases in day-to-day avoidance responses, demonstrating therapeutic effects. The simulator produced sense of presence. Cybersickness occurred primarily during the first session, indicating habituation effect. It was concluded that the Virtua Therapy simulator is an appropriate device for behavioral therapy.

Potential Applications

Virtual reality, the ability to view and interact with virtual environments, has changed the way the world solves problems and accomplishes goals. The ability to control a person’s perceptions and interactions with a virtual environment allows programmers to create situations that can be used in numerous fields. Virtual interaction can go from a computer program to an immersive experience with realistic sounds, smells, visuals, and even touch. Research in virtual reality has covered human interaction with virtual reality, different potential applications, and different techniques in creating the virtual environments. This paper reviews several key areas of virtual reality technology and related applications. An application that has large implications for our research is the control of robotic systems. Robotic systems are only as smart as their programming. This limitation often limits the utility of robotic applications in otherwise desirable circumstances. Virtual reality technologies offer the ability to couple the intelligence of a human operator with a physical robotic implementation through a user-friendly virtualized interface. This early-stage research aims to develop a technological foundation that will ultimately lead to a virtual teleoperation interface for robotics in hazardous applications. The resulting system may have applications in nuclear material handling, chemical and pharmaceutical manufacturing, and biomedical research fields.

Virtual reality (VR) has been a prominent idea for exploring new worlds beyond the physical, and in recent decades, it has evolved in many aspects. The notion of immersion and the sense of presence in VR gained new definitions as technological advances took place. However, even today, we can question whether the degrees of immersion achieved through this technology are profound and felt. A fundamental aspect is the sense of embodiment in the virtual space. To what extent do we feel embodied in virtual environments? In this publication, the authors present works that challenge and question the embodiment sensation in VR, specifically in the artistic aspect. They present initial reflections about embodiment in virtuality and analyze the technologies adopted in creating interactive artworks prepared for galleries and theater stage, questioning the sensations caused by the visual embodiment in virtual reality under the perspective of both the audience and the performer.

This paper describes the development of using virtual reality for work content in one application area over a decade. Virtual reality technology has developed rapidly; from walk-in CAVE-like virtual environments to head-mounted displays within a decade. In this paper, the development is studied through the lens of diffusion of innovation theory, which focuses not only on innovation itself, but also on the social system. The development of virtual technology is studied by one case, which is cabin design in the mobile work machine industry. This design process has been especially suitable for using virtual reality technology.
