Following Touchpad screens there go 3D ones! The witness of it is SpaceTop 3D transparent desktop. In front of this monitor you can work with all the files in 3D-space. In other words, this super-duper device allows users actually „reach into“ their computer, and move files and data with their hands. It is like physical intrusion into a digital world. A transparent LED screen, 3D graphics and camera-monitored gesture controls –practically all that is required to create augmented reality interface. I doubt, whether it is more handy that the ordinary two-dimensional interaction with your computer, but it is definitely the step forward in tech development!
