The Aerial Imaging (AI) Plate, developed by Asukanet, is a next-generation display device which can form an image which appears to be floating in midair from light that passes through it. By combining this device with sensors, it is also possible to interact with the projected images.
The viewing angle of the display is plus/minus 20 degrees from an axis at 45 degrees to the plate, so the image can only be seen by people within that area. So for example, if this display is utilized for bank ATMs, the image can only be seen by the current ATM user, preventing others from seeing what data is input. Another advantage is that because the device itself isn’t touched, the display won’t get covered in fingerprints.
