Fingertracking

Our lightweight solution for hand- and fingertracking

The Fingertracking device is an add-on to the ART tracking system, which allows you to track the orientation of the hand and the position of the fingers. It is wireless, works for one as well as for both hands (4 hands with 2 users) and is available in two versions:

  • 5finger pure optical
  • 3finger with tactile feedback

 

Vibro-tactile Fingertracking2 in industrial applications

ART's vibro-tactile Fingertracking allows the integration of the hands of 1-2 persons acting in virtual simulations, with a millimeter accuracy of the finger movement. Also, additional objects (e.g., steering wheel, dashboard, rearview mirror) can be determined and animated with the same accuracy. The vibro-tactile feedback enables the user to feel the vibration at his/her fingertips when touching objects in the virtual world. The system can be used for ergonomics analysis, maintenance simulations, buildability analysis and other applications that require the interaction of a hand with objects in the virtual space.

FINGERTRACKING2
  • Haptic feedback in three fingers
  • Compatibility with high frame rates of ARTTRACK5
  • Intensity of the vibration can be controlled
  • Various sizes for finger thimbles
  • Support in Siemens PS, DeltaGen, EON ICube 8, IC.IDO, IPSI Server, TechViz, Virtalis, VR Concept

FINGERTRACKING2 pure
  • Compatibility with high frame rates of ARTTRACK5
  • Various sizes for finger thimbles
  • Support in Siemens PS, DeltaGen, EON ICube 8, IC.IDO, IPSI Server, TechViz, Virtalis, VR Concept

The Fingertracking device consists of
  • an active hand target for affixing to the back of the hand. Synchronization is provided with a modulated flash and the low voltage power is provided with a rechargeable battery
  •  three active finger markers, each consisting of an IR LED with diffusing sphere, a fixture for the finger tip and flexible wires.

The active markers are time-sequentially addressed and controlled by the active hand target unit.


The output data consists of
  • position and orientation of the back of the hand
  • number of tracked fingers as well as a distinguishing value for right and left hands,
  • position and orientation of the outermost phalanx, given in the hand coordinate system - Together with a radius, the position and orientation of the finger tip can be estimated.
  • angles between the single phalanxes as well as their lengths - These values are estimated using tracked markers and empirical data.
