Virtual reality

The increasing use of digital mock-up is a recommended pathway towards costs minimisation, design process optimisation, training and maintenance.

List institute develops interactive simulation software technologies for Virtual Reality (VR) industrial applications. These technologies will allow either to simulate manipulations and interactions with the whole system including rigid, articulated or deformable parts (like cables) directly on the digital mock-up either to validate a scenario including the operator in order to study the work station’s ergonomic by introducing its avatar inside the dynamic simulation.

Focused on the interactive simulation cores, our research teams on Virtual Reality activities go beyond research until reaching the application side thus answering their industrial partners’ different contexts of usage (car manufacturing, aeronautics, energy and health)

Among our academic partners

CNRS, ISIR (Paris VI), LIMSI, LAAS, LIRMM, INRIA, IFSTTAR, UCBL (Claude Bernard University, Lyon - France), IRCCYN, EMN (Mines Nantes, France).

Assets

  • Link between XDE Physics interactive simulation cores and virtual reality (VR) interaction and visualisation equipment: multi-screen stereovision (CAVE), gesture tracking, virtual and augmented reality headsets, haptic interfaces…
  • Physical interactive simulations fidelity and precision (on multi-body and multi-touch systems with irregular dynamic)

Major technologies

Flexible components’ realistic digital simulation (cables)

Description

Most of assembling or dismantling parts virtual reality (VR) simulation tools do not take into account flexible components such as cables or they consider them as rigid.

Tacking into account deformable structures during large-scale movements meaning tacking into account the absence of geometric linearity and consistency is a major asset of XDE Physics simulation core technology. Based on exactly geometric beam models this core technology allows simulating with exact fidelity and in real-time cables, cylinders and others components mechanical behaviour (bending, twisting, coupling…) inside industrial digital mock-ups.

Applications

Wiring harness installation studies, maintenance or implantation process validation.

Major projects

Virtual human body dynamic simulation

Description

A work task ergonomic evaluation is actually mainly based on the posture analysis and on the human body virtual simulation, both technics relying on kinematic and geometric approaches. By simulating the multi-body system’s dynamic (which is actually the operator’s avatar) and its interactions with the environment and, by monitoring the whole combination through a “whole body motion control” approach, we can clearly observe and quantify the articulations’ efforts at stake and their distribution through the human body on a specific work situation (heavy weigh manipulation, body rebalancing…).

Applications

Work station diagnosis, ergonomic studies, musculoskeletal disorders prevention, simulation for cobotics.

 


Major projects

Mixed reality : coupling augmented reality with interactive simulation

Description

The alliance between vision readjustment algorithms in augmented reality (AR) and interactive simulation algorithms in virtual reality (VR) allows validating virtual operational elements on industrial parts or environments (parts movement, equipment, elements of process, work station configuration).

Applications

Decision making support for technical operations in industrial environment
