Targets

Many geometries, also customized

Targets consists of several markers (minimum 4), and will give the 6DOF (degrees of freedom). Here also, we distinguish between passive and active types. In addition to our standard targets we offer several construction sets for your own targets and customized developments.

Passive glasses targets

For head tracking in passive or active stereo systems, tracking targets must be affixed to the stereo glasses. ART offers lightweight standard targets as well as several adapted targets (e.g. clip-on) for a range of commercially available stereo glasses.

For some glasses brands we offer the smaller and less obtrusive target geometry 8 (e.g. XPT8) additionally to the bigger, function optimized geometries 4 to 6.

The Technical Datasheet shows an overview of our availble targets in different geometries.

Passive hand & tree targets

Hand 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. Available models: HT23, HT25, HT26, HT27, HT29 through HT32 .

Claw target

The claw target looks just the same as the hand target, but comes in a bigger size and is equipped with bigger markers. Available models: 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. Available models: LHT1 and LHT2.

Tree target

Originally designed for tracking HMDs, the tree target is a general-purpose target for tracking from longer distances (see picture above). It is equipped with 20 mm markers. Available models: TT1 through TT5.


Customized targets

In addition to our standard target collection, we specialise in creating non-standard targets customized to your specifications, varying size or radiant power, using passive or active markers. If you have special requirements regarding the target design, we can help by developing an appropriate rapid prototyping layout.

Target for Logitech Gamepad F710

As a special solution for gaming applications we designed a target for the Gamepad by Logitech. Of course it can be adapted to other Gamepad geometries.    

Sensics zSight Target

A special target for the Sensics zSight SXGA HMD is built with coated markers for a robust tracking solution. Two different target geometries are available to allow concurrent usage of two HMDs in one tracking system.  

Target for NVisor SX 60

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

Robust Passive Targets

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.


Self-made targets

Self-made targets allow for the flexibility which developers and researchers need for testing purposes. Upon request ART provides the corresponding material for passive and active targets, such as retroreflective foil or electronics.

If you want to build up your own targets, you have to apply only a few simple rules:

  • A target consists of at least 4 markers in a fixed constellation.
  • The minimum marker distance within a target should exceed 3 cm.
  • All distances of all markers in a target should differ by at least 5 mm.

Should you want to track more than one self-made target in your setup, there are additional aspects you have to consider:

The difficulty of creating self-made targets for one tracking setup increases with the number of targets.

The marker distances within a target serve as a key to identify that target. More precisely, any subset of 4 markers and the corresponding marker distances are enough for identification. Any two targets with similar marker constellations will not be distinguishable and risk being incorrectly identified. This becomes a more and more complicated problem the more targets you want to use. The risk in constructing a new target is that, without knowing it, you may create a constellation of markers which is similar to one of the precalculated ART targets.

A self-made target may not work together with standard or future ART targets.

If you want to use your self-made targets together with standard ART targets, we can help by checking for dangerous similarities between both target sets. Please note that currently we do not offer calculations to check for similarities within the set of your self-made targets. If you need a large set of targets, purchasing our precalculated ones will ensure that the problem of similarity within a set does not occur.
 

Active Targets

Fingertracking

Our Fingertracking targets use small and robust active markers, allowing a compact design with higher wearing comfort than the gloves you typically find in VR setups.

Robust active targets

An active target will be designed individually for each customer and tool, in order to make it perfectly fit to the geometry of the tool. The power supply can be directly sourced from the screwdriver. The target design ensures that it can be tracked in nearly every position.
