Janus

Transparent display has become one of the icons of the future, as demonstrated in many science-fiction movies and future scenarios of the computer industry. And now the future is here. Some companies are introducing transparent displays. Academic researchers are actively suggesting innovative ways to utilize transparent displays. But these advanced displays are still subject to the lateral-inversion problem: text or figures that appear normal on one side appear inverted on the other side. Another problem is lack of privacy, because all content on the screen is visible from both sides.

Recent research has not solved these problems Some displays use a translucent fabric screen to realize a double-sided display, which overcomes lateral inversion and privacy problems, but it also limits transparency, which is an essential requirement to guarantee “workspace awareness” for both parties interacting through a transparent display.

This demonstration introduces a novel technique to realize a transparent double-sided display without sacrificing transparency. The first prototype, Janus, is simply a double-sided POV display. Users on each side can see independently displayed images, while scenes behind the screen are also clearly visible. The transparency of the display is determined mostly by the width of the display bar. In the current prototype, the transparency is about 95%.
