Building Intelligent Environments with Smart-Its
At SIGGRAPH 2003 Emerging Technologies


Smart-Its are small context-aware computers that can be attached to everyday objects. If you need a coffee-cup that knows if it is full or empty, a table that tracks the objects on it, or a wine bottle that can tell if it has been stored correctly – attach a Smart-It!

The Smart-Its project is interested in a far-reaching vision of computation embedded in the world. To communicate this vision to a larger audience, we created a demonstration proposal for the Emerging Technologies section of the SIGGRAPH 2003 conference on Computer Graphics and Interactive Techniques in San Diego, USA. This year, Emerging Technologies recieved over 120 submissons. 21 of those were chosen for exhibition at the conference, and Building Intelligent Environments with Smart-Its was one of them.

 

SIGGRAPH 2003 had over 24.000 visitors, and the Emerging Technologies was one of the main attractions. Thousands of people attended the Smart-Its demo and talked to the exhbitions team, composed of people from Viktoria Institute, Lancaster University, ETH Zurich and Teco.

The exhibition

There were three main components included in the exhibition:


A demonstration of proactive furniture assembly was constructed by the Perceptual Computing and Computer Vision Group at ETH Zurich

An intelligent environment based on load sensing was constructed by the Ubicomp Group at Lancaster University

Finally, the Smart-Its platform and technology was demonstrated by Teco, University of Karlsruhe.

Below are a number of clickable images that show parts of the exhibition in more detail. For more technical information, refer to the presentation slides.

Pro-Active Furniture Assembly

In the furniture assembly demo, the various pieces of a flat-pack piece of furniture were equipped with Smart-Its sensors and LED lights.

The sensors detect the actions of the user and the current stage in the assembly.
The LEDs guide the user to the correct next action; green lights means that the action is correct, whereas red lights indicate that  something is wrong.

Intelligent Environments with Load Sensing

The intelligent environments demo showed a number of objects equipped with Smart-Its: A table with load sensing in each leg, four chairs with pressure sensors under the seat, and a jug and two glasses with pressure sensors at the bottom.
Each of the objects broadcast information about their current state. By combining the information, it is possible to re-create the state of the entire environment: where each object is on the table, if someone is sitting in a chair, and so on. We can even find out if a glass is empty or full, or if a person is sitting at the front or back of the seat!
Finally, a server collects all the information and projects a view of the current state of the environment on a screen above the table. (Note that the silver vase is not shown - it was not part of our intelligent environment but decoration added by the SIGGRAPH staff!)

Presentation

For the first time at this SIGGRAPH, Emerging Technologies contributors were given the opportunity to present their work in a talk. We talked about the philosphy behind Smart-Its, the various versions of the hardware, and the technical details behind the Emerging Technologies exhibition.

Media coverage

A number of magazines, radio shows and television programs covered the Emerging Technologies exhibition in general and Smart-Its in particular. Here is a representative selection.

Where is pro-active furniture assembly when you really need it?!
