In some high-tech movies, you can often see people making gestures in the air at will, and you can input and query information. For a long time, everyone has regarded it as a classic section of science fiction. Today, this technology has been transformed into reality. This may be something that many people did not dare to predict but has become a reality.

In fact, the earliest short-focus lens technology was applied to the keyboard. Since the appearance of the wall-mounted TV and computer all-in-one, all researchers have wanted to use a method to turn the traditional plug-in keyboard into a wireless keyboard, and then into a projection keyboard. After constant attempts, this technology quickly turned into reality. But for many people, such achievements are obviously not enough. Using short-throw projection technology to make touch displays available everywhere can truly meet everyone's needs.

Many people believe that in accordance with this trend, in the near future, perhaps as long as a short-throw projector, a network, and a screen or white wall that can be projected, it can complete the bridge that can be turned into a touch display everywhere in science fiction. In other words, with the development of new technologies, this design will no longer be rare.
