What is the key factor for effectiveness in VR applications?
User presence—defined by how engaged and immersed the user feels.
What influences user presence in VR?
A combination of technical factors (e.g., resolution, FoV) and user factors (e.g., emotion, agency, personality).
What is a major challenge with VR hardware?
It remains limited by computational power, portability, and compromises in battery life, resolution, and refresh rate.
Why is Field of View (FoV) important in VR?
It affects user immersion and presence, but increasing FoV requires more computing resources.
What human traits significantly impact VR presence?
Emotion, agency, and suggestibility have been shown to influence presence more than technical features.
What is the PEA model?
A model proposed by Jicol et al. (2021) that explores Presence as an interaction between Emotion and Agency.
What did the TAP-Fear model show?
FoV and realism do not directly affect presence; their impact is moderated by user agency and fear.
What was concluded from TAP-Fear study?
Human factors like agency and fear are more predictive of presence than hardware factors like FoV or realism.
What is imaginative suggestibility?
The ability to experience imaginary scenarios as if real, which correlates with higher presence in VR.
What was found about gender and suggestibility in VR presence?
Suggestibility, not gender, drove social and spatial presence; both influenced self-presence.
What challenge does physical exertion pose for VR emotion recognition?
It introduces physiological noise, making it hard to distinguish between affective and exertion-induced changes.
What are individualised and dynamic VR experiences?
Adaptive VR systems that respond to user traits, behaviors, and emotional states to enhance engagement.
What data is useful for adapting VR experiences?
User behavior, preferences, body posture, personality traits, and accessibility needs.
What is the ultimate potential of adaptive VR?
Creating personalized content in shared environments, expanding accessibility, and increasing user engagement.
What are the main challenges for dynamic VR?
Lack of models for adaptation, sensor technology limitations, processing pipelines, and data collection hurdles.
What is embodiment in VR?
The experience of owning, controlling, and feeling located within a virtual body or avatar.
What are the three components of embodiment?
Body ownership, agency, and self-location.
What is an avatar in VR?
A self-representation that can be embodied in virtual environments, influencing behavior and perception.
What is the Proteus Effect?
The phenomenon where an avatar’s characteristics can influence the user’s attitudes, behavior, and cognition.
What did Waltemate et al. (2018) study show?
Personalized avatars increase virtual body ownership, presence, and emotional response.
What are the three main research questions in the PhD project?
- Does avatar personalisation and photorealism influence perception and embodiment? 2. Do personalisation and motor control affect deceptive behavior? 3. Do they influence moral decision-making?
What was manipulated in Study 1?
Photorealism and personalisation of avatars.
What were the dependent variables in Study 1?
Embodiment, self-identification, and avatar perception.
What was the key finding from Study 1?
Photorealism and personalisation were perceptually positive and enhanced embodiment.
