Atmosphere in Virtual Reality

This document discusses different dimensions of reality including physical, mixed, virtual, and mental realities. It presents a continuum between reality and fiction, and how virtual reality fits within this continuum. The document also discusses how visual perception of genres may differ between monitors and head-mounted displays, with gender and genre both playing a role. It further explores the concept of mapping virtual textures to physical materials to improve integration of virtual and real environments. A study is presented that evaluated matches between various textures and materials.

- 2. Atmosphere and Reality In this context we define atmosphere as a mood caused by the surrounding environment. Different dimensions of reality exist.
- 3. Dimensions of Reality Physical Reality Mixed Reality Virtual Reality Mental Reality
- 4. Dimensions of Reality Physical Reality is the state of things as they actually exist as a substantial embodiment.
- 5. Dimensions of Reality Mixed Reality is the merging of real and virtual worlds where physical and digital objects co- exist.
- 6. Dimensions of Reality Virtual Reality is the illusion of some environment triggered by external simulated stimuli. It can be observed, explored or manipulated and it feels to exist.
- 7. Dimensions of Reality Mental Reality is based on the inner state of the mind including memories, daydreams and planned activities and might be triggered by outside stimuli. It is artificial, fictitious, fictional, imagery, intangible and exists only in our fantasies and dreams.
- 8. Fiction-Reality Continuum The dimensions of reality is only one aspect. Another important aspect is the content or type of fiction. Therefore we have to define a continuum considering both types of dimensions.

- 42. Summary Visual Perception Setting has to be different between monitor and HMD. Setting varies for different genres. Significant gender difference (we don’t have an explanation yet).

Virtual space needs to be discussed on a broad basis including technique, fiction, architecture, content, formats, society, self-awareness, identity, belongings, …
