part I

capture reality
1) pointcloud data - 3d - laida - laserscan data - the car drives through the streets - and mesures data

2)capture reality:projector, camera and rope - to scan 3d objects

3) photogrammetric Reconstruction: to reconstruct fassads, meshlab - program,
part II
Representing Reality
Urban Shape Grammer,
CGA-Shape from
Shape grammer: hierarchical box-split
split values: absolute (kleiner 0)

part III
the interface:
the cave
mulitouch wall - small prototype
HeyeWall - Prototypic Work
Intelligent Room - Deskotheque - Prof.Schmalstieg
Public Interaction:

City 2.0
IT History:
1970-2000 from kilo o mega to gigabytes
2000-2030: From Tera - to Peta to Exabytes
22Petabytes: Earth in 15cm resolution
6 Petabytes: 100 years of full HD video
Consequence: City Lab technology will be more and more important
From Desktop to City-size processing

1) Inter Operability and standards - CITY OPERATING SYSTEM
Luxembourg: City-wide Free Wireless

SotA: Interne. Exchange USB sticks
Desperatel needed: inegrated approach

City wide Conten management
City wide Resource management
City wide User rights management
Ciy wie Security
Robust technology no technical hurdles

2.Ineractive Applications in the Public Space
Meaningful non-contact interaction metaphorical

Public Interaction
SotA: City full of moving images...but al just static animations: movies

Involvement requires participation
Strongest participiation: Immersion (eintauchen) - the display reacts on the user
Important: Meaningful interaction - grandma compliant
Still to be solved: what is the killer - apllication

Bare-hands non-contact interaction

www.nauralinteraction.org
optical flow - basic technology for tracking

ReacTable- DataflowGraph Music

Every Wall a Display
SotA: Flat panel display in shop window
Future: Slo, cheap reflective displays
active: Light emission competes with sunlight
reflecive: Power needed only for changing the image - sunlight helps!Interesting: New Styria building in Graz -
Some consulting w.r.t. reflective displays
Painted balls on wire, bubbles in black water, colored balloons, airport displays

Important: Cost less than 1cent
Displays anyhere
Ray Painting

Computationally aware Goods
RFID Technology - ID von Usern wird aufgenommen

Computer can identiy all individual components o real environment
SotA: RFID used for billing consumer goods, nd for routing slow mils (UPS etc)
Future: UWB as universal replacement: USB, Bluetooh, LAN
spontanous networks - no server required

Universe contains about 10hoch 56 atome
conseuence: 100 decimal digits enough for enumeratin every human-made good

CITY WIKI

Virtual Homelessness
Fundmental conradiction of VR/internet:
Inernet not bound o specific location - ORTLOS
Humans are bound to specific loation

Idea: Bind internet to location
City 2.0: User-generated city
New buildings- idealized buildings
Breaking anonymity of modern suburbs
collective city memory

Task of municipality: Display content form inhabitians in the ihabited environment
