Dual Camera Magic Lens for Handheld AR Sketching

Abstract : One challenge of supporting in-situ sketching tasks with Magic Lenses on handheld Augmented Reality systems is to provide accurate and robust pose tracking without disrupting the sketching experience. Typical tracking approaches rely on the back-facing camera both for tracking and providing the view of the physical scene. This typically requires a fiducial to be in the scene which can disrupt the sketching experience on a blank sheet of paper. We address this challenge by proposing a Dual Camera Magic Lens approach. Specifically, we use the front facing camera for tracking while the back camera concurrently provides the view of the scene. Preliminary evaluation on a virtual tracing task with an off-the-shelf handheld device suggests that the Dual Camera Magic Lens approach has the potential to be both faster and lead to a higher perceived satisfaction compared to Magic Lens and Static Peephole interfaces.
