Abstract
A wearable system is shown that presents one or more heads-up displays to the wearer. A data source provides information to an image generator that is sufficient to generate one or more display images, which are still or moving, characters or graphical displays. The output image from the image generator passes through a lens, reflects off a curved mirror, and passes back through the lens the other way. The image then passes through two non-doublet lenses, between which an intermediate image exists. The image reflects off the “lens,” or visor, of the glasses and proceeds to the pupil of the wearer's eye. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.
