Keywords : Computer graphics, image animation, physics-based modélisation et simulation physique, topological modeling, haptics and force feedback, appplication to graphics creation.
The general goal of this thesis is to design the first ever system for visual arts that combine, in real time, physics-based simulation, haptics force feedback interaction, and topological modeling.
We will :
- Produce a new analysis of the various levels that must be combined to produce relevant animated images : physics, topology, geometry, optics, and their combinations
- Set up a new modeling and simulation pipeline, that efficiently organize these various components
The fundamental bottlenecks are :
- The new questions raised, for animated images, by assambling together a physics-based modeler and a real time interactive simulator
- The questions tied to the introduction of an explicit level of topological modeling, downstream physics based simulation
- The set of a series of modular topo-geometric means that can be acted in real time
Experimental work will consider an emblematic, new and motivating case : « haptic-powered multisensory fractures and tearing ».
Sujet de thèse : Acquisition, Coding, Processing, Analysis, Edition of Gesture and Movement Signals, in the context of force feedback interaction (in French)
Mots clés : gesture signals due to gesture interaction, force-feedback, coding, signal porcessing and analysis, signal edition and representation, computer sciences, art creation (music, visual creation..)
While there is an increasing need to improve the quality of multisensori-motor interaction of human with virtual worlds to produce high quality digitial contents, the thesis targets coordinated discoveries on the 5 main aspects of the gesture and motion signals : (1) Captation, (2) Coding, (3) Processing, (4) Analysis, (5) Edition.
These signals are of major importance, and play a central role, in the context of man-computer multisensori-motor interaction. There is a need, today, to develop both knowledge related to these signals, and knowhows related to their exploitation.
A specific focus will be given to signals produced in the case of a gesture interaction employing a force-feedback device.
The application domain proposed for this thesis is the context of performance arts (music, interactive visual arts, ...), where gesture interaction is a major vector of expressivity.
Sujet de thèse : Sensori-motricity of interaction with sigital worlds : towards force-feedback gesture technologies adapted to interactive computer music (in French)
Keywords : Cognitive Sciences, gesture interaction, haptics, force-feedback systems, computer sciences, musical creation
Gestural force-feedback systems are essential to reintroduce instrumentality in the context of gesture interaction with digital worlds. However, force feedback devices are complex and expensive. This limits their true use outside of research labs.
This thesis focuses on this bottleneck, by studying, in the context of musical creation, technological requirements related to force-feedback systems for musical interaction, without damaging the core quality of the instrumental exercise.
Two main axis are concerned.
1. Questioning the concept of instrumentality and its technological requirements.
This axis will produce knowledge related to the conditions, thresholds, simplification strategies and adaptative transpositions of force feedback systems, so as to implement an informed adaptation of their performances to the task at hand.
1. Situated experimentations in the context of interactive musical creation
Musical application is appropriate to this thesis, since it is remarkably demanding in terms of instrumentality. Musical situated experimentations, with training and professional musicians, will enable a "full-scale" study of the introduction of a “true instrumentality” in musical digital context.
