The development of head-mounted display virtual reality systems (e.g., Oculus Rift, HTC Vive) has resulted in an increasing need to represent the physical world while immersed in the virtual. Current research has focused on representing static objects in the physical room, but there has been little research into notifying VR users of changes in the environment. This study investigates how different sensory modalities affect noticeability and comprehension of notifications designed to alert head-mounted display users when a person enters his/her area of use. In addition, this study investigates how the use of an orientation type notification aids in perception of alerts that manifest outside a virtual reality users’ visual field. Results of a survey indicated that participants perceived the auditory modality as more effective regardless of notification type. An experiment corroborated these findings for the person notifications; however, the visual modality was in practice more effective for orientation notifications.

Hamilton Anxiety

Abstract Introduction: Anxiety disorders impact a large number of population all over the world, prohibiting them from undertaking everyday tasks such as driving, staying in crowded places, or dealing with strangers. The Hamilton anxiety (HAM-A) scale is the first rating Questionnaire for determining the sign anxiety symptoms. HAM-A is a 14 point scale containing a clinician-based questionnaire that has been utilized as a self-scored survey based on both physical and psychological symptoms. The components of questionnaires for analyzing the depressive or anxious symptoms are developed and tested in medical practice with great success. Virtual Reality (VR) is a computer-simulated world that allows the user to feel as they are physically present in it. Oculus rift is a VR ski-masked shaped goggle having a better and deeper understanding of the range and user experiences that will help to guide future efforts.Method: The cross-sectional observational study will be including 70 participants aged 18 to 32 from Ravi Nair College of Physiotherapy, India for the study. With intervention, the duration of analysis of the study will be of 6 months. HAM-A scale is used to evaluate the symptoms of anxiety in people before they show up on the oculus rift.Discussion: The study will evaluate the severity of anxiety before going to VR surrounding. Virtual reality devices are more popular, many studies have been undertaken on the construction and validation of interfaces, but more research is needed on anxiety before entering a virtual reality environment has been limited; specifically, There are only a few techniques that may be used to measure anxiety in a virtual reality surrounding.The Institutional Ethical Clearance reference number for this study is RNPC/IEC/2020-21/0012.

This paper presents an immersive virtual reality system (IVRS) that has been designed for unilateral amputees in order to reduce the phantom limb pain (PLP). The patient’s healthy limb is tracked by using a motion sensor. Data of the limb in motion are used as input parameters to move the phantom limb in the immersive virtual reality system. In this way, the patient has the illusion of moving the phantom limb while moving the real and contra-lateral limb. The system has been implemented by using low cost and open technologies, and combines the Oculus Rift SDK2 device, the LeapMotion device, a motion sensor, and an engine for interactive 3D content and gaming generation (Unity 3D). The Oculus Rift head mounted display is used to provide the immersive experience.

Abstract. Previous research on inattentional blindness (IB) has focused almost entirely on the visual modality. This study extends the paradigm by pairing visual with auditory stimuli. New visual and auditory stimuli were created to investigate the phenomenon of inattention in visual, auditory, and paired modality. The goal of the study was to assess to what extent the pairing of visual and auditory modality fosters the detection of change. Participants watched a video sequence and counted predetermined words in a spoken text. IB and inattentional deafness occurred in about 40% of participants when attention was engaged by this difficult (auditory) counting task. Most importantly, participants detected the changes considerably more often (88%) when the change occurred in both modalities rather than just one. One possible reason for the drastic reduction of IB or deafness in a multimodal context is that discrepancy between expected and encountered course of events proportionally increases across sensory modalities.

Five experiments are reported in which a perceptual interaction between simultaneous brief events was investigated. Subjects judged whether a briefly presented stimulus was flickering or not. Performance was much more error prone when a similar unattended stimulus was presented at a relatively remote position in the visual field, thus confirming previous findings. Interference was obtained for stimuli presented both peripherally and centrally in the visual field. The effect was not confined to large stimuli, but the larger the interfering stimulus the greater the effect it had. Events in the auditory modality interfered with judgements made in the visual modality. Possible mechanisms for the interaction are discussed.

Virtual Theater

This study compares watching a film in a traditional theater setting to watching the same film in a virtual theater using a virtual reality (VR) head-mounted display (HMD). The study seeks to determine whether watching a film in a virtual theater is a comfortable experience that viewers can tolerate; and whether watching in VR produces similar feelings of identification, transportation, and enjoyment for the films as watching in a traditional theater. Using the Oculus Rift DK2 HMD and the Riftmax virtual theater software, participants watched either Signs or Ferris Bueller's Day Off in a virtual theater. Other participants watched the same films in a traditional theater setting, and independent comparisons were made. Results indicate that over 90% of the VR participants were able to watch the entire movie in the virtual theater, and feelings of identification, transportation, and enjoyment were quite similar between conditions. Differences found were attributable to the films' content, with an interaction between VR and theater conditions. Implications and future research are discussed.

Abstract A human mission to Mars has long been advocated. As each year the scientific researches bring mankind closer to establishing human habitats on Mars, the question of how astronauts can sustain themselves whilst away from the blue planet becomes crucial. The project presented in this paper aims at designing and developing the Virtual Reality (VR) simulation of an inflatable modular greenhouse featuring a system that manages the growth of the plants and helps the astronauts control and monitor the whole greenhouse more extensively. The use of VR technology allows simulating an immersive environment of a Mars habitat highlighting its greenhouse overcoming the limitation of physical locations. Wearing the Oculus Rift head-mounted display (HMD) while holding Oculus Rift Touch Controllers, astronauts or Mars exploration enthusiasts could experience the highly interactive and realistic environment. Its goal is to provide training and evaluative simulations of astronauts’ basic tasks and performances in the greenhouse on Mars while testing the growing method of hydroponics equipped with a smart growing controlling and monitoring system.

Serious games for health are those that are not aimed solely at entertainment, but rather at supporting health treatments. In this paper, we develop and assess the proposal of a Virtual Reality (VR) game aimed at supporting Sensory Processing Disorder (SPD) treatment. SPD is a condition which affects the integration and processing of the various stimuli coming from inside and outside of the body and its treatment involves providing patients with controlled sensory stimuli. Our goal is to investigate whether a Virtual Reality game that can stimulate different sensory systems could be useful in SPD treatment. In order to do so, we have designed and developed Imaginator, a VR Roller Coaster Game connected with a Head Mounted-Display (HMD) which can be customized by therapists to adjust its stimuli to different patients’ needs in therapy. Imaginator was assessed by five occupational therapists through its use in their treatment sessions. Each therapist had the game available in their therapy environment for around 2–3 weeks. They were instructed to use the game whenever they thought it could be interesting to a patient’s treatment. After the trial period, they were interviewed about their experience in using the game and their perception of its impact in therapy sessions. Our results show that therapists in general perceived Imaginator as having a positive effects in patients’ treatment. They noticed that it was able to stimulate different senses, and they reported that in some cases it was able to help patients relax, increase their concentration and even work as an encouragement to explore similar activities in the physical world. There were a few patients who experienced some adverse reactions, such as nausea, but nothing that they felt was worrying or that could prevent the game from being used.
