Some time ago Apple has filled patent applications that describe improvements in head-mounted displays such as helmet or glasses. This sounds interesting because it may lead to iGlasses, a product that would contain two small display screens with magnifying lenses inside glasses. Apple has stated that this type of approach provides a wider field of view, which is desirable and additionally creates a more natural viewing situation for a user. Since Apple has products with very small video screens like iPods, this type of innovation could really benefit their product line. Time will tell when iGlasses will become a reality, but there are also some problems like, for example, the fact that such glasses could damage the wearer’s vision.
