An experiment was conducted in a Cave-like environment to explore the relationship between physiological responses and breaks in presence and utterances by virtual characters towards the participants. Twenty people explored a virtual environment (VE) that depicted a virtual bar scenario. The experiment was divided into a training and an experimental phase. During the experimental phase breaks in presence (BIPs) in the form of whiteouts of the VE scenario were induced for 2 s at four equally… 
Responses of Participants During an Immersive Virtual Environment Experience
The results suggest that the lowest presence was achieved with the higher fidelity characters but the less varied textures, and there is some evidence also that variations in the level of visual realism based the texture strategy used was associated with changes in mental stress.
Variations in physiological responses of participants during different stages of an immersive virtual environment experiment
It was found that participants typically show a stress response during the training phase and a Stress response towards the end of the simulation of the urban experience.
The Effects of Physiologically-Adaptive Virtual Environment on User’s Sense of Presence
It was found a significant difference for the physiological measures between the NS and DS condition, showing that it was possible to dynamically modulate the VR experience using real-time HR and EDA to increase the effectiveness of VR experiences.
Physiological response to a speech stressor presented in a virtual reality environment.
The use of VR technology may be a viable alternative to methods currently employed in presenting stressful tasks with the potential advantage of decreased variability in the audience response to the participants' performance.
The Impact of a Character Posture Model on the Communication of Affect in an Immersive Virtual Environment
The quantitative results indicate that posture plays an important role in the communication of affect by virtual characters and the importance of designing holistically congruent virtual characters especially in immersive settings is discussed.
Breaks in Presence in Virtual Environments: An Analysis of Blood Flow Velocity Responses
Blood flow velocity (BFV) in middle cerebral arteries (MCAs) has been monitored using transcranial Doppler ultrasound during the exposure to a virtual environment and an increasing trend was observed during the recovery periods.
The physiological mirror—a system for unconscious control of a virtual environment through physiological activity
It is claimed that anchoring of subjective bodily states to a virtual reality (VR) can enhance a person’s sense of realism of the VR and ultimately create a stronger relationship between humans and the VR.
Participant responses to virtual agents in immersive virtual environments
The results show that participants are affected and respond to virtual humans in a significant manner provided that an appropriate behavioural model is used.
Immersive Virtual Environments for Emotional Engineering: Description and Preliminary Results
The obtained results will help furniture companies identify the senses that have more influence on emotions and will be the basis for new studies about user needs in the sector of furniture and interior decoration.
Physiological responses to stressful work situations in low-immersive virtual environments
The paper analyzes physiological responses to different visual representations of stressful work activities. A between-subject experiment was conducted to analyze differences in heart rate (HR) and


Physiological Responses to Breaks in Presence: A Pilot Study
It is found that the evidence does not contradict the hypothesis that BIPs are observable as events in the SCR and HR time series, and the evidence was based on 60 subjects for whom heart rate was recorded and 20 for whom SCR was recorded.
Physiological measures of presence in stressful virtual environments
Physiological reaction satisfied the requirements for a measure of presence, change in skin conductance did to a lesser extent, and that change inskin temperature did not, and inclusion of a passive haptic element in the VE significantly increased presence and that for presence evoked.
Measuring Presence in Virtual Environments: A Presence Questionnaire
Combined results from four experiments lead to the following conclusions: the PQ and ITQ are internally consistent measures with high reliability; there is a weak but consistent positive relation between presence and task performance in VEs; individuals who report more simulator sickness symptoms in VE report less presence than those who report fewer symptoms.
A Virtual Presence Counter
A new measure for presence in immersive virtual environments (VEs) that is based on data that can be unobtrusively obtained during the course of a VE experience is described and lends support to interaction paradigms that are based on maximizing the match between sensory data and proprioception.
More Breaks Less Presence
The hypothesis is that the greater the number of BIPs the lower the reported overall presence should be, on the average.
Temporal and Spatial Variations in Presence: A Qualitative Analysis
This paper presents the qualitative findings from an experiment designed to investigate breaks in presence. Participants spent approximately 5 minutes in an immersive CAVE-like system depicting a
A Framework for Immersive Virtual Environments (FIVE): Speculations on the Role of Presence in Virtual Environments
It is proposed that the degree of immersion can be objectively assessed as the characteristics of a technology, and has dimensions such as the extent to which a display system can deliver an inclusive, extensive, surrounding, and vivid illusion of virtual environment to a participant.
Using Presence Questionnaires in Reality
It is concluded that, although such questionnaires may be useful when all subjects experience the same type of environment, their utility is doubtful for the comparison of experiences across environments, such as immersive virtual compared to real, or desktop compared to immersive virtual.
The Influence of Dynamic Shadows on Presence in Immersive Virtual Environments
The experiment suggests that for visually dominant subjects, the great the extent of shadow phenomena in the virtual environment, the greater the sense of presence.

It is argued that a scientific basis for presence as it's usually understood in virtual environments research, can not be established on the basis of postexperience presence questionnaires alone, and that presence researchers must move away from heavy reliance on questionnaires in order to make any progress.
