Lautriv Chromagnon/Medusa guides the interactive visitor through
different ambiences in diverse ways: Digital Mode (Virtual Reality),
stereoscopic 3D vision interactive and analog interactive in real
time (telepresence).
Material:
metal, rubber, fiberglass and wood. Low-tech and widespread material
for the body, high-tech material for the intelligent skin.
Dimensions:
Height: 200 cm, width: 130 cm, depth: 100 cm

The name Lautriv comes from the reversal
of the word Virtual=Lautriv. Chromagnon is a word made up of Chroma
key + Cromagnon. Lautriv Chromagnon/Medusa is part of a Lautriv
Community, a family of interactive sculputure. The members of
this community will have their own: identity, objects, dreams,
desires, ... the concept is to place some of the members or objects
of Lautriv's community in "neuralgic points" (museums, cultural
spaces, etc.) of the world and to interconnect them to an electronic
network, always interacting through their eyes, skin, body.

Medusa is placed in a room 5 x 6 meters large, immerse in a play
of shadows breaking the darkness. When the public step in her space,
the interaction starts. There are no boundaries between her skin
and the surrounding environment. Her sensibility is spread in the
whole room.
About the interaction:
1. Enter into Medusa's room
2. Contact her
3. Touch her intelligent skin
4. Look through her eyes
5. Navigate!.. interact
6. Keep touching her!!!! Medusa's body is a vehicle of artistic
comunication.
The interactivity starts in the artistic input given by the sculpture.
Her body painting recalls a telematic poem, it is a prolongation
of her inner electronic life.
The interacting visitor can revele his presence to Lautriv Chromagnon
touching the skin. Twenty virtual worlds, corresponding to Medusa's
inner life, have been design. These worlds have been integrated
with 3D sound and holophonic effects. The sound scenography has
been designed to envolve the whole sensibility of the visitor. There
is a sophisticate relationship between the sound and the synesthesic
perception of it. The body works here as interface both for the
visitor and for Medusa
Digital skin
The surface of Medusa has been provided by an array od tactile
sensors based on the use of polyvinylydene fluoride (PVDF), a piezoelectric
polymer which possess very interesting mechanical and electrical
properties. The high sensitivity of the used PVDF coupled with their
flexibility allowed the realisation of "skin-like" sensors ablo
to perform measurements of pressure variation, hardness and surface
texture of touched objects. The "intelligent skin" of Medusa has
been realised by using thin strips of PVDF (25 micron thick). From
each strip, an array of sensor has been obtained by properly etching
a metallized surface, while a common electrode is mantained on the
opposite side. The arrays, mounted onto a robber substrate in order
to give a higher sensitivity and skillfully located on the surface
of medusa are able to detect (discriminate) the position and the
intensity of soft touch onto the body.

Two types of Lautrivs will be created. A) One is to be exclusively
experimental and artistic B) The other to be projected for the cultural
market as a "MUSEUM NAVIGATOR" for museums, research centers, foundations,
etc. The type of media, technology, interactivity, content and container
can be projected ad hoc, inherent to the message or the concept
to be communicated and adapted to the cultural environment of the
space where it will be placed.
