Abstract
One embodiment of the invention includes an image display device. The image display device includes a projector for emitting an image, a screen on which the image is projected, and a mirror for reflecting the image from the projector toward the screen. The mirror has a planar surface reflection area and a curved surface reflection area continuous with the planar reflection area. Images projected onto the mirror are reflected with no distortion in one area and distortion in another area. The distorted area fills a portion of a user's peripheral vision. Also, the distorted area allows some embodiments of the invention to provide the user with a greater sense of motion.
