Script
This scenario is an ironic fiction of a commercialised AR-living-room. When entering living-room scenario the visitor steps into the subjective experience of a future AR-Décors user who is trying out a demo-version of a new habitat collection.

Upon entering the habitat AQUA the following text will be heard “Dive into the water world. Enjoy the relaxing movements and sounds of the surrounding waters after a hard day’s work. Encounter exotic animals and plants at your home.”

For ORBIT the voice suggests:


But the two offers turn out to be simple announcements of future implementations. Only the habitat NATURA can be accessed for a limited period of time with limited functionalities.

Using a handheld device and an immersive graphical user interface the viewer can compose her/his personal environment. She/he can remove the real walls of the living room by clicking, opening the view to a wide landscape. She/he can accurately place virtual objects referring to the indoor or outdoor space, change space with atmospheric effects and change daytime dimming the real and virtual lamps and light temperatures of the living room.

Sound for daytime:

Sound for the night:

In short intervals, television-like advertisements interrupt the scene. A voice accompanies some animated graphics:
“Subconsciously redesign your living-room by wearing the comfortable wireless bio-feedback-sensor (BFS-XS).”
“The ultra light and compact face mounted display (FMD-19) is now available as a family bundle.”

“With the additional 3D-tracking-cam (TC-2600) you can integrate the virtual scenes more accurately into your home now.”
When the visitor decides to leave the demo or the time limit exceeds, the advertisement for the professional version is displayed:
“Congratulations! You just composed a very inspiring environment! If you want to create more enriched environments please try AR-Décors PRO. AR-Décors PRO includes a brand new animal collection and tools for controlling the balance of your designed ecosystem. Thank you for using AR-Décors, the most advanced AR-habitat system!”

Investigation topics
AUDIOVISUAL DISSOLUTION/EXTENSION OF THE REAL SPACE
In this scenario the user decomposes real space by clicking away parts of the walls, floor and ceiling. The possibility of dissolving the real world instead of nesting virtual elements in it is an interesting approach. The borders between the real and the virtual are more difficult to blur in this scenario. Tests with dissolved borders and downgrading of the digitally generated image have been made.

As the same IKEA furniture from the "real world" is always a part of the scene, as a constant parameter. Therefore, its integration and relation to changing virtual worlds representing environmental situations is a major issue. Sound and colour play a crucial role.

LIGHT AND COLOUR TEMPERATURE
By changing from day to night the lamps of the real and the virtual world adapt brightness and colour temperature. The seamless change of atmosphere in both worlds simultaneously is a further investigation topic.

FICTION OF A DAY-TO-DAY SITUATION USING THE SUBJECTIVE PERSPECTIVE – ‘EGO-SHOOTER’
First scripts for 'cross world' story telling have been elaborated. Narrative elements placed in the real and the virtual world can form a continuous stream of content. The subjective view was introduced later. by implementing an audio assistant (female voice) and setting up the scenario as a commercial product the user is immersed into the experience of a fictive technology user.

AUDIOVISUAL 3D GRAPHICAL USER INTERFACE (GUI) WITHIN THE HMD
Instead of using only one 2D-GUI plane in front of the viewer’s line of vision several independent planes are animated to enhance layout and linking options. Different positions and interaction movements of the planes have been examined. Coloured layers with different transparency values can alter the constant relation between the menu buttons and the background representing the image of reality.
