At Brother World Japan 2010, Brother Industries presented the AiRScouter, a head-mounted transparent display that projects images directly onto the retina.
This display uses the "persistence of vision" effect to project pictures onto the retina. It does this by shining a light, at a level of brightness that's safe for the eyes, and moving the light at high speed. The images projected on the retina are recognized by the visual sense, making it seem just as if they are floating just in front of the eyes.
"When people hear the term "see-through display," I wonder what sort of display method they think of. This display creates a mysterious effect, making it look as if there's a 16-inch screen floating one meter in front of the eyes, and the scenery behind the screen seems transparent as well."
"Firstly, we expect this display will be used in industrial applications. Using the AirScouter, it's possible to look at a manual or the like while working on site. The advantage of this is, it reduces the time lost in moving around. Also, a camera can be attached, so pictures of the work site can be sent to head office. This makes it possible to work in collaboration, while receiving instructions from experts in the office."
Apart from industrial applications, this display could be used in AR technology, combining the real and virtual worlds. In the future, it'll be possible to connect a smartphone to the AiRScouter, so the display of the smartphone can be seen on the head-mounted display.
"First of all, we'd like to market this display for industrial applications in Japan. After that, we'd like it to be used in consumer products worldwide."
