TELLURIS : the real-time simulator

In the 70's ACROE announced in various underlying papers its hypothesis regarding the importance of the instrumental act and multi-sensority for musical and visual creation. In other words :

  • musically, the importance of the instrumental act in the construction of the musical sense ;
  • in animation, the benefit of animation by manipulation in addition to conventional animation methods (ie. cartoons).

For these reasons ACROE designed, as early as 1979, a first multisensory real-time simulator. It has allowed, for the first time, to simulate the physical behavior of virtual sound-producing objects and deformable images, simple yet handled in real-time with the help of a force-feedback gestural system (haptic device). In 1981, ACROE  designed a dedicated processor (cf PHD Berberyan, 1982) thanks to which were tested the first musical sounds through real-time instrumental play. In 1983, thanks to a dedicated architecture based on vector processors and custom output synchronization cards, the first complete virtual experience was achieved : force-feedback gesture, sound and deformable image (cf. Dedicated simulators : the retroactive tennis game)

In 1995, with the help of the IMAG institute, the Ministry of Culture and the Région Rhône-Alpes, J.L.Florens and assistants C.Uhl and O.Giraud designed the fourth model of the real-time multisensory simulator, the "TELLURIS simulator", based on standard UNIX architecture. It runs and synchronizes a kernel of Silicon Graphics and dedicated processors : visualization, audio output, gestural input/output.

Combining portability, computational power and genericity, this latest model can be used for working on real-time multisensory models as well as a prototyping platform for dedicated simulators.
