Interactive Transportable Architecture:
peyote's iTube and Sensing Places' Natural Interfaces
This project is displayed in Vortechs, in the Sails Pavilion.
The iTube is an example of interactive transportable and
reconfigurable architecture that incorporates
unencumbered real-time body tracking and gesture recognition to explore a
3D cityscape and a brain-like web-based information space.
Like transportable dreams, the iTube enables multimedia experiences
(almost) everywhere. Within its interior, an interactive
rear-projection screen is steered by the user via real-time body interaction. 3D sound ensures an immersive experience. The technology is permanently integrated within the telescope-like, extendible iTube architecture, which ensures a very fast assembly and dismantling
With today's technology, anyone can navigate in sophisticated 3D graphical environments and play engaging computer games in highly realistic and fascinating 3D landscapes. But this progress has not been paralleled by equivalent advances in human-machine interfaces to facilitate access and displacement in virtual worlds. People still use quite primitive and limiting interfaces: the joystick, button-activated game consoles, or the computer keyboard itself.
Full immersion and skillful exploration of 3D graphical environments are
limited by the users ability to apply these interfaces, and the consequences
of repetitive use often involve undesired and painful medical consequences
to wrists, fingers, arms, or shoulders. New, more natural
interfaces are needed to navigate inside virtual worlds.
In the iTube, participants use natural interfaces to explore the virtual 3D spaces projected onto its large screen with a small set of pointing and command
gestures. A robust computer-vision-based, full-body immersive interface empowers surfing inside the cityscape. A separate computer-vision-based hand-tracking and gesture-recognition system drives navigation inside the
BrainSpace. These interfaces work in real time and require only standard computers and small cameras. They do not require special calibration procedures, do not limit body movements with cables or tethers, nor do they require wearing special suits with markers for tracking.
The SIGGRAPH 2003 iTube features two applications. One allows visitors to explore a cityscape in 3D and surf in real time from the tops of
buildings to street-traffic level. Defying gravity to dive in and out
of space and time, the participant becomes part and observer of a new
interpretation of urban patterns like traffic, noise, and street life in a

The other application, called BrainSpace, allows users to use natural hand gestures (no
gloves or markers) to browse through a 3D brain-like matrix
that contains information extracted from the World
Transportable architecture that embeds the means to communicate with real
or imaginary digital information spaces in a natural fashion offers
unprecedented opportunities to make immersive, body-driven multimedia
experiences available to the public almost everywhere.
The iTube project's goal is to provide a mobile media-hosting and display
device for indoor and outdoor public installations that has the full
features and functionality that people expect from a 21st-century virtual-reality
system. Its interaction modality with real and imaginary virtual
displays is natural, unencumbering, and futuristic. By using
computer-vision-based, natural, human-machines interfaces, it achieves the vision the public is already familiar with from movies such as
"Minority Report," in which Tom Cruise uses hand gestures to browse through electronic data on a large screen.
