Vibrotactile rendering of camera motion for bimanual experience of first-person view videos

We propose a vibrotactile rendering method for the motion of a camera in first-person view videos that enables people to feel the movement of the camera with both hands. Concretely, we consider an arrangement of two vibrotactile actuators to render panning movements on the horizontal axis as vibrations that move from hand to hand, and to represent sudden vertical displacements of the camera as transient vibrations on both hands. We investigate three representation methods for the panning motion based on the estimated velocity and acceleration of the camera and a combination of both. In a preliminary user experiment, we observed favorable effects of applying our proposed rendering method on the perceived realism and satisfaction associated with the experience of watching a video.
