>Live Wire (Dangling String), 1995

>In 1995, as an artist-in-residence at Xerox PARC in Palo Alto, California under the guidance of Mark Weiser, she created an art installation made up of LED cables that lit up relative to the amount of internet traffic. The work is now seen as one of the first examples of ambient or "calm" technology.

>Designing Calm Technology:
Mark Weiser and John Seely Brown,
Xerox PARC,
December 21, 1995.

>Introduction: Bits flowing through the wires of a computer network are ordinarily invisible. But a radically new tool shows those bits through motion, sound, and even touch. It communicates both light and heavy network traffic. Its output is so beautifully integrated with human information processing that one does not even need to be looking at it or near it to take advantage of its peripheral clues. It takes no space on your existing computer screen, and in fact does not use or contain a computer at all. It uses no software, only a few dollars in hardware, and can be shared by many people at the same time. It is called the "Dangling String".

>Created by artist Natalie Jeremijenko, the "Dangling String" is an 8 foot piece of plastic spaghetti that hangs from a small electric motor mounted in the ceiling. The motor is electrically connected to a nearby Ethernet cable, so that each bit of information that goes past causes a tiny twitch of the motor. A very busy network causes a madly whirling string with a characteristic noise; a quiet network causes only a small twitch every few seconds. Placed in an unused corner of a hallway, the long string is visible and audible from many offices without being obtrusive. It is fun and useful. The Dangling String meets a key challenge in technology design for the next decade: how to create calm technology.

>We have struggled for some time to understand the design of calm technology, and our thoughts are still incomplete and perhaps even a bit confused. Nonetheless, we believe that calm technology may be the most important design problem of the twenty-first century, and it is time to begin the dialogue.

>Dangling String: Let's return to the dangling string. At first it creates a new center of attention just by being unique. But this center soon becomes peripheral as the gentle waving of the string moves easily to the background. That the string can be both seen and heard helps by increasing the clues for peripheral attunement.

>The dangling string increases our peripheral reach to the formerly inaccessible network traffic. While screen displays of traffic are common, their symbols require interpretation and attention, and do not peripheralize well. The string, in part because it is actually in the physical world, has a better impedance match with our brain's peripheral nerve centers.

>In Conclusion: It seems contradictory to say, in the face of frequent complaints about information overload, that more information could be encalming. It seems almost nonsensical to say that the way to become attuned to more information is to attend to it less. It is these apparently bizarre features that may account for why so few designs properly take into account center and periphery to achieve an increased sense of locatedness. But such designs are crucial. Once we are located in a world, the door is opened to social interactions among shared things in that world. As we learn to design calm technology, we will enrich not only our space of artifacts, but also our opportunities for being with other people. Thus may design of calm technology come to play a central role in a more humanly empowered twenty-first century.

>HISTORY: Media wire

>Mark Weiser in 1988 articulated the idea of ubiquitous computing for the first time at the Computer Science Lab at Xerox Palo Alto Research Center (PARC). He coined the phrase “ubiquitous computing” and wrote several papers on it. The initial forms of ubiquitous computing include tabs, pads, and boards. The first ever known ubiquitous system was the artist Natalie Jeremijenko’s Live Wire or Dangling String situated at Xerox PARC, under the technical leadership of Mark Weiser.

>Mark Weiser suggested the idea of enormous number of ubiquitous computers embedding into everything in our everyday life so that we use them anytime, anywhere without the knowledge of them. Today, ubiquitous computing is still at an early phase as it requires revolutionary software and hardware technologies.
