Presence refers to the emotional state of users where their motivation for thinking and acting arises based on the perception of the entities in a virtual world. The immersion level of users can vary when they interact with different media content, which may result in different levels of presence especially in a virtual reality (VR) environment. This study investigates how user characteristics, such as gender, immersion level, and emotional valence on VR, are related to the three elements of presence effects (attention, enjoyment, and memory). A VR story was created and used as an immersive stimulus in an experiment, which was presented through a head-mounted display (HMD) equipped with an eye tracker that collected the participants’ eye gaze data during the experiment. A total of 53 university students (26 females, 27 males), with an age range from 20 to 29 years old (mean 23.8), participated in the experiment. A set of pre- and post-questionnaires were used as a subjective measure to support the evidence of relationships among the presence effects and user characteristics. The results showed that user characteristics, such as gender, immersion level, and emotional valence, affected their level of presence, however, there is no evidence that attention is associated with enjoyment or memory.

Rehabilitation Programs

Since several years scientists are carrying on research about innovative systems, based on robotics, mechatronics devices and IT tools – especially the graphical ones – to support patients in rehabilitation programs for rescuing from various brain damages due to adverse events as stroke. Training sessions with a combination of robot and virtual reality (VR) lead to better rehabilitation outcomes than using only a robot and evidence from the field proved the importance of the use of VR interfaces in rehabilitation. The main aim of such a kind of environments is to monitor, motivate and drive the patient during the rehabilitation sessions. These systems mainly provide motor guidance and multimedia communication channels also measuring patients' performance and other observable variables. The approach implemented is usually based on gaming, where the patient has the key role to perform certain tasks or movements for controlling the game in the correct way and exercise the injured part. According to daily experience from physiotherapists, different aspects related to the physical and self-perceived patients' state revealed to have a fundamental role in influencing the rehabilitation session. Indeed, the treatment result depends not only on motor skills but also on patient's personal behavior and feelings that are not directly investigable, observable and measurable from outside. In other words this kind of elements can only be assessed by subjective measurements (as questions, interviews, narratives) revealing the point of view of the patient. Moreover, the emotional state has implications at different levels: on one hand, it is important to evaluate if the single rehabilitation session affects the emotional state of the patient, on the other, if the performance was influenced by this state. Some answers of a questionnaire administrated to post-stroke patients in a previous study underlined also the need for the patient to focus his/her attention on the trained body portion and the relevance of a visual feedback on movements to increase self-awareness on the action performed, avoiding any possible distraction derived from other kind of tasks and related visual/auditory stimuli. Patient-centered models of care are actually becoming increasingly common among rehabilitation clinical settings. They help to focus the therapy on improving the treatment of those deficiencies that most influence the quality of life of the patient. Another important aspect is represented by the relationship with the caregiver that in virtually assisted rehabilitation would not be direct anymore and will need to be mediated without completely loosing natural interaction. According to this patient centered vision, and in order to reduce possible side effects related to semi-automatic rehabilitation systems, it has been studied and developed a system which has not the aim of merely entertain the patient but to focalize the rehabilitation on him/her as a proactive character aware of what is happening and of the quality of the work performed.

Personalised Therapy

One of the most frequent health problems is stress. It has been linked to negative effects on employee well-being in many occupations, and it is considered responsible for many physical and psychological problems. Traditional in-person relaxation therapy has proven to be effective in reducing stress. However, it has some drawbacks such as high cost, required infrastructure and the need for qualified trainers. Relaxation therapy in Virtual Reality (VR) tries to solve these problems. However, one aspect has received little attention, that is personalised therapy. Indeed, while many studies show the need for patient-tailored relaxation exercises, little existing work focuses on personalised VR content. One reason for this is the complexity of recognising emotions, which is required for emotion-based adaptive VR. In this work, a method for adapting VR content to the emotional state of the user is presented. This model has been applied in a VR relaxation therapy application, which adapts to the user’s emotional state utilising a heuristic optimiser. Simulations have proven the performance and usability of the emotion model. Additionally, this paper explores the impact of the order in which adaptations are performed on the effectiveness of the relaxation experience.

<p>The virtual human play vital roles in virtual reality and game. The process of Enriching the virtual human through their expression is one of the aspect that most researcher studied and improved. This study aims to demonstrate the combination of facial action units (FACS) and facial muscle to produce a realistic facial expression. The result of experiment succeed on producing particular expression such as anger, happy, sad which are able to convey the emotional state of the virtual human. This achievement is believed to bring full mental immersion towards virtual human and audience. The future works will able to generate a complex virtual human expression that combine physical factos such as wrinkle, fluid dynamics for tears or sweating.</p>

AbstractCompared to traditional screen-based media, virtual reality (VR) generally leads to stronger feelings of presence. The current study aimed to investigate whether playing games in VR resulted in a stronger sense of presence than playing on a TV, and whether these feelings of presence affected players’ emotional and physiological responses to the games. Two experiments were conducted among 128 students, comparing the effects of playing either a survival horror game (N = 59) or a first-person shooter (N = 69) on a TV or in VR on physiological and subjective fear, hostility and enjoyment. Results showed that playing games in VR resulted in a stronger sense of presence, lower heart rate variability and a stronger subjective sense of fear. The feeling of presence thereby mediated the effects of VR on fear. The effects of playing a first-person shooter in VR on hostility were mixed, and gaming in VR was not more enjoyable than on TV. Regardless of the type of game or display medium, hostility increased significantly post-play. This study provides evidence that commercial VR games can affect feelings of presence and the physiological and emotional state of players.

ABSTRACTA modern person constantly changes the environment of his mental activity, moving real into an immersive environment, for example, from the surrounding reality to the information environment of a smartphone and back. This kind of transition is needed to satisfy many of the cognitive and emotional needs of people. The transition from a real physical environment to virtual reality (VR) with the help of a special headset, for example, the Oculus Rift or HTC vive, occurs less often, causing less frequent emotional state. If at the same time the emotional state of a person is investigated, then, as a rule, the manifestation of heart rate variability (HRV) is used as an indicator. However, there are relatively few studies in the literature on physiological responses using HRV during the perception of VR content. The results of such studies are extrapolated to data evoked in HRV manifestations by stimuli of real and virtual environments. We studied HRV in 55 participants while they were in the flow of VR content of different dynamics. The results were analyzed by statistically testing the hypothesis of the effect of VR immersion and the effect of transitions between realities on HRV manifestations, as well as the effect of VR flow dynamics on HRV. The results showed that the perception of the VR flow and the content transitions made in it determine the change in HRV in the form of such parameters as LF and the Baevsky Index, which can be considered as markers of immersion in VR. An increase in emotional arousal with sequential participation in virtual games in one virtual stream determines the manifestations of HRV - HR, Moda and PAR.The results contribute to understanding the possibilities of using VR technology to recognize emotions during the transition between the natural environment and VR, as well as to determine the level of emotional arousal when immersed in the changing flow of virtual content. These studies are important for the study of the psychology of emotions in the VR flow paradigm.
