| A televirtual event By Maurice Benayoun, Music by Martin Matalon - 1995 | A televirtual world première September 19 to 24, 1995 | The Tunnel Under the Atlantic (Le Tunnel sous l'Atlantique) is an experimental work using televirtuality that allows users situated on each side of the Atlantic Ocean, in Paris and in Montreal, to meet and interact in a virtual space they have created together. | video | ![](../tunnel401.jpg) | A person enters on each side of the virtual tunnel that links the Museum of Comtemporary Art in Montreal with the Georges Pompidou's Center in Paris. As the two progressively advance toward one another, the surface of the passageway they are in the process of forging, reveals the equivalent of geological strata which are transformed in this context into iconographic strata. These discoveries enhance the dialogue between the two protagonists. Each participant shares a complementary part of the same musical composition. Finally, on both sides of the ocean, a group of spectators can watch the progression of these two explorers and their verbal exchanges are projected on a giant screen. | Freedom of exploration is one of the major characteristic of The Tunnel Under the Atlantic. The tunnels created are likely to evolve in many different directions: they may go up or down, turn right or left, regardless of the angle of rotation. Users will thus be able to seek out fragments of images of which they have only seen certain details. It becomes obvious that this project presents an interactive relationship, that clearly surpasses the level of mere arborescence. | ![](../tunnel33.jpg) | ![](../montreal2.jpg) | The Tunnel Under the Atlantic attains a higher degree of interactivity, due to a «supervisor» program that monitors users' more or less chaotic behavior, as they develop their exploration and interests. Toward this end, the system must administer three different types of data transmitted in both directions between Paris and Montreal: spatial coordinates and the orientation of each explorer, the sound of the dialogue and commentaries of both participants, and finally a picture of the face of each protagonist at the moment they meet (approximately 5 low-resolution images per second). | On both sides of the Atlantic, the Tunnel uses an ONYX SGI station, two Indy WorkStations, an SGI digital camera, a Sharp projector, a ISDN line and a quadraphonic sound system. | ![](ressources/tunnel0_small.jpg) | The Tunnel Under the Atlantic Director: Maurice Benayoun Computer development: David Nahon & Tristan Lorach (Z-A Production) Musical creation: Martin Matalon Musical assistants : Xavier Chabot, Frederic Voisin, Xavier Bordelais ( IRCAM ) Producer: Stéphane Singier / Karen Benarrouch (Z-A Production) A Public Command of the Délégation aux Arts Plastiques, French Ministry of Culture A coproduction of Z-A Production / IRCAM / Mission Recherche et Technologies du Ministère de la Culture / Centre Georges Pompidou.
