A guidance technique for motion tracking with a handheld camera using auditory feedback

Abstract

We introduce a novel guidance technique based on auditory feedback for a handheld video camera. Tracking a moving object with a handheld camera is a difficult task, especially when the camera operator follows the target, because it is difficult to see through the viewfinder at the same time as following the target. The proposed technique provides auditory feedback via a headphone, which assists the operator to keep the target in sight. Two feedback sounds are introduced: three-dimensional (3D) audio and amplitude modulation (AM)-based sonification.
