Standard Interfaces
To be able to use the ART tracking system in VR or AR applications, one needs an interface. Lots of VR systems have developed a direct interface using the SDK coming from ART. If you are also interested in developing your own interface use one of the following standard interfaces, please contact us.

trackd™
trackd, provided by Mechdyne, is a small "daemon" application, that acts like a standard interface for tracking and input devices. A variety of VR and motion tracking software applications already support trackd. It is available for several operating systems (e.g. Linux, Solaris, HP-UX, Windows). With trackd you are able to use any ART target or Flystick. There is no interface for the ART Fingertracking.
VRPN (Virtual-Reality Peripheral Network)
VRPN is a set of classes within a library, provided by the NIH National Research Resource in Molecular Graphics and Microscopy at the University of North Carolina at Chapel Hill.
It can be implemented into application programs to get a network-transparent interface to a set of trackers and other devices. As with trackd, you can use any target or Flystick, but no Fingertracking.
VR Juggler
VR Juggler (Open Source Virtual Reality Tools) is a research project headed by Dr. Carolina Cruz-Neira at Iowa State University's Virtual Reality Applications Center.
It provides Virtual Reality software developers with a suite of application programming interfaces (APIs) including display surfaces, object tracking, selection and navigation, graphics rendering engines and graphical user interfaces. The VR Juggler includes the Gadgeteer module, which provides the support for ART tracking.
Open Tracker
OpenTracker was developed by a group at the Vienna University of Technology as part of the augmented reality software Studierstube. It provides an open software architecture (C++ class library) based on a highly modular design and a configuration syntax based on XML.
