The system relies on A. R. T. Using DELMIA virtual assembly and maintenance simulation platform and RTID Human-machine engineering real-time interactive system as the core driving engine, the real-time 3d virtual assembly content and process, through the virtual reality display environment to display the way of three-dimensional display to the user, and through the Haption force feedback device for virtual assembly and maintenance interaction. Here’s how it works:

System features:

1) High Performance Professional Grade Optical Tracking System

PC control host

　　◇ Standard frame structure, easy to install and maintain;

　　◇ The 6-DOF position and direction of the tracking target are calculated

　　◇ Equipped with SYNCCARD2, can achieve the synchronization of multiple cameras, and according to the need to install stereo glasses and other external components

Tracking Cameras

　　◇ High Precision Position and direction measurement;

　　◇ Through the local area network to achieve low delay, high-speed data transmission;

　　◇ No Optical chromaticity brightness interference between cameras;

　　◇ Up to 16 cameras of various types can be installed;

　　◇ It can resist the interference of magnetic, electric and sound waves

　　◇There is an optimized solution for CAVE environment

　　Target and mark

　　◇ Virtual reality dedicated interactive devices, such as: Flystick2, fingerprint tracking, etc. 

　　◇ Various shapes of non-interactive target, including Stereo glasses tracking point, head-mounted device tracking point;

　　◇ Can carry on the target point user customization, and can quickly carry on the target point calibration;

2)Development of virtual assembly and virtual maintenance simulation
　　The Conduit software, developed by Mechdyne specifically for Dasso V5 products (Catia V5, DELMIA V5, Enovia DMU, etc.) , is based on a distributed architecture that enables multi-channel, large-scene immersive browsing and interaction of V5 raw data.

　　The MECHDYNE CONDUIT SOFTWARE FRONT END TAKES OPENGL calls from desktop V5 applications (Catia, DELMIA, Enovia DMU, etc.) and distributes them to the aggregator management and rendering nodes, the rendering is processed on each node via the Conduit backend and distributed computing and rendered locally on each node, with each node responsible for a projection channel for the output, the synchronization and edge fusion of the output images from each channel is accomplished by the Conduit software and the SGI Visual Workstation.

　　Real-Time Interaction for Human(RTI)

　　The application of RTI makes it possible to record the movements of the human body directly in the program by Optical Motion Capture System, which reduces a lot of development time, and more relevant to the actual character’s behavior pattern. The recorded interactive action information can be used directly in Delmia V5 for further ergonomics analysis.

RTI provides the following capabilities:
　　◇ Simulation Setup

　　◆ Various Mannequins can be selected from the Delmia repository;

　　◆ Independent joint can be activated or closed;

　　◆ Definable tools and moving parts;

　　◆ It can automatically load 3d data into interactive physical simulation environment

　　◇ Operation Equipment Management

　　◆ Optical tracking system compatible with real time motion capture; current support for A.R.T.TM  , VICON TM and MAC TM;

　　◆ Supports 3DCONNEXION'S 6D mouse;

　　◆ VIRTUOSE AND INCA series of force feedback devices and systems supporting Haption;

　　◇ Simulation process management

　　◆ Start, stop, pause, or restart operations can be set;

　　◆ Controls can be mounted or unloaded on a 3D model;

　　◆ Motion capture devices can be calibrated automatically, and virtual human models can be matched or unbound with a mouse click

　　◇ Real-time physical simulation

　　◆ The range of action of the operator can be adjusted to conform to the virtual human model

　　◆ Integrating the motion elements of the virtual human model, including the Boundary Constraint of the joints;

　　◆ Looking up the interference information of the contact node and simulating the human action such as stopping/sliding/twisting of the contact position;

　　◆ Real-time update character view and 3D display window;

　　◇ Capture and record of simulation process

　　◆ The pose information of the virtual human model including joint curvature can be recorded in real time

　　◆ The recorded human model information can be created as Delmia human-machine task for subsequent data reconstruction and Statistical Analysis;

Real-time motion and mechanism constraintReal Time Movement and Kinematics Constraints
　　Based on the Advanced Constraint Analysis Algorithm, RTI Human avoids the dynamic errors and inefficiency which may occur in the process of real-time Human action in the traditional reverse dynamic analysis, and makes the Human action more realistic and accurate.

Real-Time Recording Trajectory analysis
　　RTI Human can record all kinds of Human action/posture information in real time, and play back, edit, analyze and reuse it.

RTI Virtual reality applications RTI Human and Virtual Reality
　　RTI Human Can combine head-mounted 2d/3d display (HMD) , immersive 3D display system(Such as: CADWALLTM, CAVETM and other three-dimensional display environment, to provide users with a unique immersion virtual reality experience.
