Naked-eye 3D displays have started to become widespread. But one of the current issues with naked-eye 3D displays is that their viewing range can be a bit narrow. In other words, if you move your head slightly away from the center of the display, you don't see proper 3D. So here, we assume that when a handheld 3D display is tilted, the viewer's head is always perpendicular to it. By continually turning the normal viewing range of the display towards the user's head, we increase the viewing range virtually, by a factor of three. In other words, we've developed technology that increases the viewing angle from about 30 degrees to about 90 degrees.
We think this display could be used in education and shopping. For example, when shopping online, people could look at goods from various angles before buying. Technology for increasing the viewing range has a very wide variety of applications. So we'd like to keep researching not only Hands On 3D, but also various other methods for increasing the 3D viewing range.
