First interaction test, Summer 2004
First sensor prototype, Le Cube's room, with Didier Bouchon.

The first sensor test directly connects, without relationship with the project, the lateral sensor movements to the depth of the lights movements.
Video recording and montage : my thanks to Marcia Lyons.

Sensor device
, 2003 - end 2006

The tracking of the viewer's head movemnts is made through a helmet, put on the viewer, emiting infra-red. The camera on the ceiling gets the data, sends them to the treatment box, connected to the computer.

Francis Bras : conception ;
Zandrine Chiri : data processing box ;
Benoit Vérant : first and second helmet (for the viewer's head).

First helmet with cable, 2005, then the second one is without cable, 2006.

Calibration
, technical photographies, Show room, Le Cube, July 2005

The calibration software was realised by Anthoni Schiochet, trained by Francis Bras and Didier Bouchon.

To calibrate the sensor (video camera + portable device) or the interactive space amounts to 'normalise' them : a few adjustments allow, through a software made to this aim, to indicate to the display software in what particulare case the installation is. The sensor and the computer will thus always perform in the same way whatever the installation space will be.

Hanged on the ceiling, the video camera focuses on the (real, concrete) ground where the viewer will move.


To calibrate the video camera requiers regular marks on the ground. These positions indicate what concrete space is related to the virtual one.

Interface between single screen and panoramic screen, interaction writing, October 2006 - in progress
Collaboration with Didier Bouchon, end of calibration, management of several screens according to installation choice.
End of choices and programming interaction rules, "grandeur nature" tests of interaction rules...

Research support (October 2006 - in progress), Institute for Visual Media, ZKM | Center for Art and Media Karlsruhe, Germany.
use of Bernd Lintermann's software for panoramic distortion of 3D content, tests in cylindrical screen.
The viewer stays inside of the screen.


Cylindrical screen or"pano-screen" used for tests, 3.3 meters diameter, ZKM.
See PanoramaFestival, PanoramaTechnology.


Interface Eye-Ocean / cylindrical screen
An initialisation file allows to change the display of the image according to the environment (in the panoramic screen or not) and thus to simulate the panorama. One can work for the panorama without the panorama, with a single screen, while integrating the shape's movements and the cyclindrical screen deformations.
The form 'automaticaly' evolves (appearing, shifting, color) according to the position/speed/orientation/behaviour of the red shred (viewer's gaze) and according to the programmed interaction rules.

April 2008 :

White circle : representation of the cyclindrical screen
Green and red squares, red line : position and orientation of the helmet/viewer
Turquoise curve : speed of the sensor
Purple curve : rotation angle of the sensor (viewer's head)

Vertical red stroke : origine of the sensor angle
Vertical white stroke : sensor aiming
Dark gray/green curved areas : visualisation of the 4 parts of the cylindrical screen where the shape moves.

Jully 2008 :



Reduction of the symbols size to limit their visual inconvenience :
Red stroke : mobile gaze of the viewer
Grey stroke : 90 degres limit, 1/4 of the panorama each.
