images by manipulating them live in real space. Commenting upon the computer installation «The Tangible Image,» realized in 1991 in collaboration with Bob O’Kane, Weibel wrote: «Neither the image nor the observer was touched, only the interface. The observers were part of the system they observed, they were in the picture, in the data of the image. A non-local distortion, a manner of displacement that was tele-correlated, distorted the image likewise. The modification of the interface modified the image at the same time.» [21] The effect resulting from this configuration consists in an identical (albeit virtual) distortion being triggered in the real, live-projected image by every touch, every change, and every manipulation (on the monitor screen). In this way the observer is in fact ‹in the picture,› while his body remains in the real space. This would be a clear example of an endo-approach to electronics. «We propose the introduction of two levels: first the endo approach to electronics and second electronics as the endo approach to the world. The nature of electronic art can only be understood as an endophysical principle since electronics itself is an endo approach


to the world. But now a double entry is possible. On the endo-gates of the model world simulated by means of the electronic arts you can read: Entrance from the world—Exit to the world.» [22] A further research direction in the field of interactive art examines possible connections between systems that are biological (human body) and artificial (virtual space). The previous analysis of the robotic, interactive installation «Terrain 01» delineated how Ulrike GabrielTerrain 01, by using a direct interface (the interactor’s brainwaves) not involving material communication, connects up the internal and external worlds in reciprocal and inverse fashion. By means of an interface that links organic activities with the generative activities of the algorithm, the interactive connection in her installation «Perceptual Arena» (1993) turns the interactor into the internal observer of an artificially generated world. The results of this connection are made visible over the projected image and so can be perceived by external observers. In this system the interactor is invited to take part in the process of creating the work, not with conventional methods
