Labdesignar: configuring multi-camera motion capture systems in augmented reality

Abstract

We present LabDesignAR, an augmented reality application to support the planning, setup, and reconfiguration of marker-based motion capture systems with multiple cameras. LabDesignAR runs on the Microsoft HoloLens and allows the user to place an arbitrary number of virtual "holographic" motion capture cameras into an arbitrary space, in situ. The holographic cameras can be arbitrarily positioned, and different lens configurations can be selected to visualize the resulting fields of view and their intersections. LabDesignAR also demonstrates a hybrid natural gestural interaction technique, implemented through a fusion of the vision-based hand tracking capabilities of an augmented reality headset and instrumented gesture recognition with an electromyography armband. The source code for LabDesignAR and its supporting components can be found online.
