Spatial Sketch System

Traditional design media (such as sketch and model making) is possessed the abilities of hand-craft expression and intuitive attention behavior for design making. It mediated to direct a key instinctive design-training behavior allows designer express their thought with convenience by hand and eye. In this paper, we purpose Spatial Sketch System which consisted with a spatial I/O interface and a VR environment. Spatial I/O interface completed with two wearable devices of S-gloves and S-glasses for design input and visual display. VR environment brings the capabilities of gesture modeling, provide designer three type of modeling functions of line, surface, and mass in architectural design training. It allows designer can implement their instinctive design-training behavior with CAD tools by spontaneously. We evaluated our system through the comparison with present CAD system, it provides users new design possibilities to create idea directly, and allow designers to operate in complicated design processes in architecture with simplicity.

Tiles prototype

Smart Architecture is characterized with their adaptability to users' needs. The interaction between users and their living environments are redefined so that buildings are autonomously responsive to human activities. Floor, as the very construct where human-building interactions take place most frequently, is chosen to initialize our attempts to make buildings "smart". We applied the concept of Cellular Automata to develop the prototype of "Smart Tile", which can be connected to each other to form an information network so that activities takes place at somewhere on the floor can be recognized and disseminated to wherever the information is needed. Most importantly, a smart floor records the dynamic configuration of interior spaces that are filled with movable objects and people.

Call for Submission: Emerging Technologies (Siggraph Asia)

Adaptation
We live in a world of unprecedented complexity, where humanity, nature, and technology must adapt to rapidly changing conditions. Digital technology can provide new answers to these challenges, but it can also pose new problems.
Our technology has become so powerful we can now control the genetic makeup of living organisms and cause holes in the ozone layer. Yet some of the most impressive breakthroughs in art and technology happen by considering the gaps and opportunities in the existing landscape - by adapting what we know to what might be. Now, as the world evolves with exponential speed, we need artists and scientists to show us the infinite possibilities of adaptation.
Emerging Technologies is a showcase for innovations that will change the way we work, live, and play. For SIGGRAPH Asia 2009, we are seeking works that show how digital technology adapts, or can help us adapt, to a world in flux. Adaptation can have many meanings, from machines that repair themselves under stress to technologies that help humans survive in adverse conditions. Adaptations can also be unexpected or unwanted. We are particularly interested in seeing examples of how computer graphics and interactive techniques are evolving to adapt to new conditions: technical, social, environmental, or something else entirely.

1. 每一塊地磚發送自身的訊息至地磚表面
2. 當地磚上方有障礙物，地磚身份由生轉為死。終止訊息的處理。
3. 每塊地磚可以獨立設定成為任一種訊息的源頭。

因此：
機器車或智慧的物件能行走在地磚皮層上，應用環境皮層的資訊執行任務。
牆、障礙物（具相當重量）滯留在地磚上，傳達出障礙的訊息到地磚。

GRACE STATE MACHINES

2007
Robot performance
Aluminium, air piston, valves, micro controlers, network switche, motion capture system, max/msp, air compressor, alogene light bulb, midi dimmer.
Collaboration: Bill Vorn, Emma Howes, Jonathan Villeneuve
Grace State Machines is a Robotic Art performance project. The name of the project is inspired by a virtual "state of grace" that could be expressed by automatons and other finite state machines. Through this project, we want to explore the close relationship between the real physical human body and machine body. We want to express the inner perceptions of both entities and how they intertwine, blend, mingle and become blurred as they interact and exchange in an intimate dialog between the organic and the artefact

Sofian Audry, Jonathan Villeneuve
In collaboration with Myriam Bessette & Samuel St-Aubin
Trace is a collaborative installation in three stages. Its design pools the plastic and conceptual concerns of the artists with a will of complementarity and exchange.
Led by a computational, sculptural and sound work, the project tries to create a physical impression in the viewer. The collective creation allows the artists to develop new aesthetic, sensory and technical approaches.
A multi-faceted work, Trace explore many sides of the same idea. Three sculptural elements give insight on a daily experience that is lived with the transformation of private space. Bulbs, wiring, textiles, dyes and bolts intertwine, carrying the fragility of livable spaces. The reality is thus diverted, revealing the ephemeral aspect of a memory that fades with the renewal of the domestic sphere.
Trace consists of three installations: L, V and S. The concept of flexibility and mobility is the basis of the work that thus adapts to its exhibition space. The development is based on a collective "work-in-progress" methodology, where each element responds to the first and influences the next.

red dot: grand prix: "Duality" by ART+COM, Berlin

Traditionally, there has always been a certain tension between art for public spaces, with its architectural associations, and the actual surroundings of a building: On the one hand, this close connection to the building limits the creative freedom, but on the other hand it is also its challenge. Installations that make use of new media and technologies today offer their designers the possibility to establish entirely novel relationships with architecture. And not only with the architecture: also with the people who live and function within it. Developed for a new building complex in the centre of Tokyo, the “Duality” installation responds to the impulses of passers-by.

The action of stepping on a six-metre-square area generates real-time virtual light waves that extend as real waves on the surface of the adjacent artificial pond. The installation aims to offer commuters flowing out of a nearby metro station a playful moment of pause and meditation; furthermore, “Duality” explores the interplay between solid and liquid, virtual and real, light waves and water waves, and is intended to counter the generic practice of architecture art with a concept that evokes identification by instantaneously implying both the location and the human beings that are present in it.


Joachim Sauter on “Media in public spaces”:

“Duality” is an installation in a public place in the city centre of Tokyo. The aim was to create an installation that, unlike many other medial art projects for public spaces, would interact with its environment thematically and react physically to passers-by. Set up as part of a walkway and an adjacent artificial pond, “Duality” acts as an interface between “liquid” (water) and “solid” (walkway), expanded by the aspects of “real” (waves of water) and “virtual” (waves of light). Due to the reactive nature of the installation, passers-by change the environment and thus experience a moment of identity with the place.
