The idea of communication at a distance always was an ambition of man and society. With the telegraph and the telephone, the relation btw time and space changed forever and opened the possibility of sending messages “ without body”, as Claudia Giannetti says in her essay “ Ars Telematic: Telecommunication, Internet and Cyberspace”.
This idea of communication at a distance and the way artists in the twenty-century worked with emergent technologies for communication or connecting remotely always seduced me.
The experiments in the late 70´s, when artists started to work with network systems to create live performances creating a real time virtual space, were an important attempt to collapsed geographic boundaries and explore connectivity.

Hole-In-Space: A Public Communication Sculpture

"A three-day, life-size, unannounced, live satellite link allowing spontaneous interaction between the public on two coasts Video cameras and rear projection screens were installed in display windows at Lincoln Center for the Performance Arts in New York and The Broadway department store, Century City, Los Angeles Each screen displayed life-size, full-figure images of people on the opposite coasts There were no signs or instructions Passers-by drawn to the windows discovered an open channel through which they could see, hear and talk with people on the other coast almost as if they were standing on the same street corner Pictured A woman on screen from New York City leans forward to visit with silhouetted people in Los Angeles"
Eduardo Kac
Interfaces

"Interfaces was a live exchange conceived and organized by Eduardo Kac which took place on December 10, 1990, between a group of artists in Chicago and another group in the Center For Creative Inquiry, at the Carnegie-Mellon University, Pittsburgh. This piece dynamically explored the formation and dissolution of identities online. It was experienced projected on a large screen in the auditorium of the The School of the Art Institute of Chicago
"Interfaces" established a visual dialogue between the participants in a way that was purposefully similar to a verbal exchange between two people -- bringing the improvised and spontaneous feed-back loop of a personal conversation to the realm of video. This "visual conversation" explored the characteristic top-to-bottom, vertical rendering of slow-scan TV (SSTV), to produce unexpected faces in real time.
Participants in Chicago were not aware of the exact images that would be transmitted by the Pittsburgh group and vice-versa. This unpredictable situation added an element of surprise to the process. As images overlapped on the screen, parts of a face (from Pittsburgh, for example) were slowly scanned over another face (previously sent by the Chicago group). Successive faces were created in the virtual space of the screen as the performance progressed.
