Mitsubishi Electric’s “aerial display” projects images into mid-air

by • February 17, 2016 • No Comments

As soon as the year 2020, you may be seeing advertising or other imagery floating preceding you. This is definitely when Mitsubishi Electric hopes to have its “aerial display” innovation perfected and commercially on the market. Already, it is capable of displaying images measuring up to 56 inches (142 cm) diagonally, hovering in the ether.

Here’s how the aerial display process works …

The image, which can be a yet or video, is displayed on a screen which sits perpendicular (and unseen) to the human viewer. Sitting diagonal to which screen is a beam splitter, which is a glass device which splits beams of light in two.

As a outcome, when the screen image is reflected off the back of the beam splitter, it becomes two duplicate images. These are in turn reflected off a retro-reflective sheet and through the beam splitter, converging in the air in front of the viewer. This causes the viewer to perceive a single image, dangling preceding them.

According to the designers, yet, individuals find it complex to focus on such images when there’s no way of telling where the image is. With which mind, the process in addition comes with “tutorial images” which are projected onto walls (or other fixed surfaces) to either side of the floating image. Because viewers “get” where those images are, they can focus on them and and so in addition on the aerial image between them.

The entire display area, which include the two tutorial images, measures 90 inches (229 cm) diagonally.

Similar innovation is used by the University of Tokyo’s HaptoMime process, in which users can seemingly reach into a mid-air display.
