Motion Capture is used to evaluate the ergonomics of human motion, in character animation to make the figures behave plausibly and in VR applications with a head-mounted display to provide an immersive experience.

The ART motion capture system uses rigid 6DOF targets which are attached to various parts of the body. A body suit is not required.  The system uses passive reflective markers, so there is no need for batteries. In standard setups we use up to 17 targets for full body motion capture. In seating buck setups we use a subset of targets to track only the upper body, head and arms. Up to two people can be full-body-tracked simultaneously. A third subject’s upper body can also be tracked at the same time.

ART-Human provides a fast and easy way to calibrate the human model by simply adding another output channel to the DTrack2 control utility’s output. With this model it is, for example, easy to carry out visualization in head-mounted display VR applications, as ART-Human takes into account the correct bone length of the individual users. The 6dj (j like joints) is a simple but effective human stick figure, which can be used for visualization purposes.

Key features:

• Single 6 DOF targets – no suit necessary
• Fast and easy calibration through ART Human
• Tracks 2 full bodies and one upper body simultaneously
• Absolute position of the human model
• Robust design with covered markers
• Interfaces to: Alaska Dynamicus, Autodesk MotionBuilder^®, Catia, Delmia, Jack, Virtools
• Free SDK available
• Add tracking of fingers with the ART Fingertracking system

ART-Human is a tool to assist motion-capture projects. The software uses the information of our highly accurate 6 degree-of-freedom (6DOF) optical targets to track a human subject. We use up to 17 ergonomically designed targets which can be worn directly on normal clothing.

For normal usage the ART-Human model is automatically calibrated, i.e. the length of each limb segment is calculated. After the targets have been attached, the calibration process is started. The process is fast and straightforward: The user simply moves arms and legs for around 20 seconds to exert the full mobility of all joints. The accuracy of the calibration is then evaluated, and the results – the length of each limb – are applied to the model.

ART-Human is now ready to send human model data in real-time to your application. We provide our own 6dj format, similar to the Fingertracking hand data format. It’s also possible to use Fingertracking with ART-Human at the same time. You can now directly use the online input of the human subject to visualize a 3D model.

Key features:

• Use of 6DOF optical tracking targets
• Fast automatic bone-length-calibration (< 1 min)
• Real-time interface to Siemens Jack, Autodesk MotionBuilder®
• Output format: 6dj
• Fully compatible with the ART Fingertracking system
