The Virtual Hand Lab (VHL) is an an augmented reality envimnment for conducting experiments in human perception and motor performance that involve grasping, manipulation, and other 3D tasks that people perform with their hands.The hardware and software testbed supports both physical and virtual objects, and object behaviors that cm be specified in advance by experimenters.A testbed for conducting experiments must provide visual stimuli that depend on the configuration of the experimental apparatus, on the specific tasks that are being studied, and on the individual characteristics of each subject.Calibration is an important concern and is the subject of this paper.A proper design leads to independent calibration steps that modularize the subsystems that require calibration and explicitly recognize and order the dependencies among them.We describe how the architecture for the VHL was designed to support independent apparatus-specific, experiment-specific, and subject-specific calibrations.The architecture offers benefits for any augmented reality environment by reducing m-calibration times and identifying appropriate modularization in the software that can result in a more robust and efficient implementation.
