From sensory dynamic perception to physical modelling, for a new kind of interactive visual representation : the body involved, driver of the dynamic visual simulation.

Cynergia is created in partneship with ACROE-ICA laboratory and relates my thoughts on motion prioperceptive perception, its possible likely representations and ACROE-ICA researchs in motion genration by Newtonian physical model (masses/interaction).

ACROE-ICA team working on this project:

Annie Luciani (director, in charge of Dynamic Visual Arts), Stephane Boeuf (Computer Engineering), Delphine Passinge (Software Engineering) and the trainees Maxime Veslin (Modelling) and Eric Tatulli (Analysis Protocol) of the Master Degree Art-Science-Technology, School of engineering in Physics, Electronics and Materials Science in Grenoble.

Physical simulation:

Broadly used in industry to size devices and to forecast behaviors, physical simulation has still an Art purpose. Cynergia involves two types of physical models of ACROE-ICA, the first to generate a visual movement, the second for a visual representation, in both cases by digital synthesis. The project is reachable only by using these models having their own dynamic behavior activated by sensoring process.

Device description, interactive intallation:

Device components: interactive pumps with force sensors, a physical modelling (the motion metaphor), and a dynamic visual simulation, reacting in real time.

The acting subject (the observer using the device) must use his/her body weight to foster synergy with the dynamic visualisation ahead. The physical model receives sensors datas and simulates a motion (in regard to the action and the force given by the acting observer), which an Art representation is cast on screen. However, since the physical modelling system has an autonomous structure and dynamic resulting, it slightly moves away from the subject movement and encourages him/her to adapt his/her action with body motions. The expected result is an interactive loop bewteen the subject's motion and the device.

Issue and research problem: the corporeal scheme

The device mobilises a subject's kinethetic perception and encourages him/her to realise his corporeal scheme. Motion tracks are transposed into the physical modelling device. Real time notion is a decisive connexion allowing to establish the following couplings:

  • from the subject motion to the involved forces sensoring process ;
  • from the sensored forces processing to the physcial modelling process ;
  • from physical modelling dynamic images generation to kinetic casting ;
  • from Art representation to the retroactive loop of the subject's body motions.

Why this system is different from traditional motion picture?

Physical visual simulation has not the same regular linear narration criterias since it depends on the body motion sensored with physical dynamic simulation, both having an unprectictable and non deecred part originating in their own behaviors evolving according to their underlying structures.

Real time and feedback notions replace the temporal linearity of successive motion pictures. Thus, visual simulation is each time new and is caused by the condition: motion and perception of the acting subject, sensoring, physical simulation. The kinetic rolling-out depends both on actions/perceptions of the subject and on the model behavior, instead of a pre-established cut.
