Google isn't the only company interested in producing wearable head-mounted displays for everyday use. Olympus has announced its latest wearable prototype called the MEG4.0, a device that clips on to standard eyeglasses and projects a 320-by-240 QVGA display right in front of your eyes. Many other companies are also working on head-mounted display technology. However, most competing concepts don't have the same application to everyday life like Glass or MEG4.0 do. Apple was recently granted a patent for a head-mounted display. The patent covers technology for “projecting a source image in a head-mounted display” that would create an “enhanced viewing experience” for the user. Canon announced in June an augmented-reality platform using head-mounted displays. Sensics was showing off its SmartGoggles 3D gaming headset in January, and Sony announced a head-mounted 3D visor for movie viewing last August. Other companies such as Microvision have also been talking up head-mounted displays since at least 2000.
