Passive Targets

A.R.T. Passive Targets
Glasses Targets

For head tracking in passive (polarized or InfiTech®) stereo systems, tracking targets must be affixed to the stereo glasses. ART offers several lightweight standard targets and a custom target for Captain® glasses for this purpose.

Glasses targets (generic) and targets for Captain® glasses

  • GT1 through GT6
  • Targets for Captain® glasses

CrystalEyes® target

Target tailored to the shutter glasses of the StereoGraphics active stereo system. These are used with CrystalEyes CE2, CE3 and CE5. The CrystalEyes CE4 is not compatible with our systems.

  • CE3T1 through CE3T6 for CrystalEyes CE2 and CE3
  • CE5T4 for CrystalEyes CE5

Target for NuVision® AGP6000 / 6100

  • C3dT4 / C3dT5

Target for Volfoni EDGE

  • EGT4 / EGT8

Target for XpanD 103

  • XPT4 / XPT8

Target for 3D Vision Pro

  • 3dVT4

Target for NVisor SX 60

Specially developed target with passive markers for the head-mounted display NVisor SX 60.

Hand & Tree Targets

Hand target (Claw target)

The hand target is designed for hands and elbows in usability/assembly studies. It is also frequently used as a small general-purpose target.

  • HT23 through HT32

The claw target looks just the same as the hand target, but comes in a bigger size and is equipped with bigger markers.

  • CT11 through CT16

Large hand target

This new hand target is designed for hand tracking in a two-camera tracking system. Its large size allows the user to make almost any movement with the hand without producing any occlusions.

  • LHT1 through LHT2

Tree target

Originally designed for tracking HMDs, the tree target is a general-purpose target for tracking from longer distances. It is equipped with 20 mm markers.

  • TT1 through TT5
Motion Capture Targets

ART provides a complete set of targets for motion capture (MoCap) purposes. All targets are 6DOF targets and can be identified by the tracking system. Up to 20 targets (including one glasses target and two hand targets) can be used at a time. All MoCap targets are available with coated markers.

A full ART MoCap target set consists of:

  • 1 Tree or glasses target (head)
  • 2 Umeris targets (shoulder)
  • 1 Dorsum target (back)
  • 2 Humerus targets (upper arm)
  • 2 Ulna targets (forearm)
  • 2 Hand targets (hand)
  • 1-3 Waist targets (waist)
  • 2 Femur targets (thigh)
  • 2 Tibia targets (shinbone)
  • 2 Foot targets (foot)

The upper body target set for the third subject consists of:

  • 1 Glasses target (head)
  • 2 Umeris targets (shoulder)
  • 2 Humerus targets (upper arm)
  • 2 Ulna targets (forearm)
  • 2 Hand targets (hand)
  • Waist target (waist)
Robust Passive Target

To track objects (e.g. tools) in industrial environments, targets have to be lightweight and robust. They should be inconspicuous and must not disturb the operators in their activity. With a target attached to both a tool and the processed object, the user can get all relevant information like position and rotation. A target can be designed with passive (ring) markers or active LED diodes.

A robust passive target uses laminated spherical markers. With the lamination the worker can touch it and it can be cleaned without damaging the reflection film. The geometry is bigger than an active target but no power supply is necessary.
