Epson constructs the Moverio glasses using micro-miniaturized projectors
in each of the glasses legs (the parts that go over the ear). The
images are then reflected off mirrors that send them edge-wise though
the glasses lenses where they are bent by a prism inside the lenses to
project images directly onto the retina. The glasses themselves are
completely transparent -- allowing the world to be viewed normally with
the tactical images overlaid on it. Thus to the user, the real-world
objects being viewed appear to have the repair information projected
directly onto them, but in fact the images are only seen by the person
wearing the glasses.
The user wears a small battery-powered Android computer on their belt --
about the size of a smartphone -- into which the images are loaded
ahead of time. WiFi connectivity allows the visual service manuals -- or
any other desired video content -- to be loaded directly into the
Epson is currently readying a second-generation of Moverio glasses
designed specifically to the specifications required by industrial
applications, such as Scope Technologies' visual service manuals. The
new model adds a video camera so that pattern matching algorithms can
precisely line up the tactical information to be overlaid directly on
the faulty parts being viewed.
The user interface in this application will be critical. If an intuitive interface is developed that allows the instructions to be scaled, overlaid on the task, and easily controlled by a working individual, this could become the next killer app for repair technicians and training users.
The capability and application of wearable electronics are still unknown. Google's youtube videos have a couple interesting show cases. Whether they will become a popular apps is still to be seen. Yet, the application area as suggested by the article are very interesting and most like be applicable to a lot of areas.
