 The PIPER framework aims to propose some alternative methodologies that can be used along current approaches. Positioning in PIPER typically starts with the Physics-based Interactive Pre-Positioning Module (or pre-positioning). The HBM is automatically transformed into a simplified model with a limited number of degrees of freedom that can be used in physics-based interactive simulation. Despite being simplified and interactive, the simulation can among others account for collisions between bones (to prevent penetration, limit range of motion, ...) and provide a rough transformation of the soft tissues. The PIPER framework aims to propose some alternative methodologies that can be used along current approaches.

-The pre-positioning process is the place where the user can input its various constraints, weight them, and compute a plausible posture (for the skeleton in particular). Constraints could also include a priori knowledge such as physiological observations or postural preferences which are not classical mechanical parameters. For now, physiological descriptions of the spinal curvature (called Spine controller) can interact with the model (e.g. collision detection on the vertebrae) during postural change.+The pre-positioning process is the place where the user can input its various constraints, weight them, and compute a plausible posture (for the skeleton in particular).
