Tracking Calibrations

I teach in the AR/VR Lab at Full Sail University in the Simulation and Visualization BS where we commonly cover bringing tracking systems together so that they can properly coexist within the same interactive application.  This usually involves some type of calibration routine.  Below are 2 recent projects that incorporate such calibrations to bring other tracking methods into the same tracked space as the VR HMD tracking equipment.  It is our goal to enlighten our students with skills and techniques necessary to prototype simulation applications.  This technique is very important to making simulation based applications such as training applications.

Both projects do this calibration with a point based sampling calibration that involves sampling various points from both tracking systems to create frames necessary to incorporate 1 tracking method into another’s frame or vice versa.

I integrated both student projects with software to display them in 3rd person mixed reality so that they can demonstrate their systems.

In this Dental Simulation below designed by a masters game design student, we have a bachelors student who has brought Polhemus magnetic tracking together with the HTC Vive tracking.

In this Virtual Pilot Trainer a Bachelor student uses a leap motion as an interactive control panel someone can touch with their hands in a Boeing cockpit.  The leap motion hand tracking is then brought together with the HTC Vive tracking with this calibration.
