Future input devices may be similar to current language input devices or scan input devices. When people want to input something, they do not need to enter the content with a keyboard, only a word or a scan can be used to input the information into the computer. In the future, there is even an input device that can get information directly from the human mind by connecting the human brain. This magical input device can convert the neural signals in your brain waves into information that can be understood by the computer and input into the computer.

I think it will be possible to develop VR technology, holographic projection, 3D printing and so on. In the future, we can print out objects we want directly through 3D printing technology, such as houses, cars and so on. The output video and pictures will also be output by holographic projection and virtual reality technology. People can feel the picture or the scene of the video.
