The method may include mapping a central portion of the forward visual field to a near-peripheral field of view, wherein the mapped central portion is displayed in a peripheral field of view using a forward display device of the head-worn device. A portion of the forward visual field may also be displayed in a peripheral field of view using a peripheral display device of the head-worn device.
