PSCHITT-PMR

Modality of the multimodal PSCHITT transport research platform, the PSCHITT-PMR platform constitutes a simulator dedicated to the movement of a Person with Reduced Mobility (PMR) in a wheelchair. It is part of the laboratory's autonomous mobility platform, and forms part of the CPER RITMEA regional PMR-Lab platform.

Presentation

Designed by LAMIH, the PSCHITT-PMR platform enables a manual or motorized wheelchair user to move around in a simulated, immersive and dynamic environment, in a safe experimental context. PSCHITT-PMR is a full-scale, medium-weight scientific facility (motorized roller bench, instrumented reconfigurable wheelchair, etc.) featuring a simulation software environment tailored to research use.

.

Implemented in several projects, the PSCHITT-PMR platform's advanced functionalities enable it to safely meet experimental needs in different usage contexts, such as:

The design, prototyping and evaluation of advanced mobility assistance systems;
The study and modeling of PMR;
Quantifying the biomechanical cost of moving;
The study of the impact of the environment on the difficulty of a trip;

Keywords

Mobility assistance, biomechanical cost

Representative projects

QBA and CapaCITIES (estimating the biomechanical cost of wheelchair travel)

Features

Simulation of wheelchair movement (dynamic, visual and sound immersion)
Interaction with the user, live or planned upstream (scripting)
Real-time information capture (user and environment)
Wheelchair geometry can be adapted
