IO2 Technology has created what could possibly be the next generation computer display. The device is called 'Heliodisplay', and it can project 3D images in mid-air. The device is designed to display images from any video source in high-resolution without the need for a screen.
The computer images can also be controlled by the user's finger and hand movements without the need for special gloves. The Heliodisplays are available with diagonal projecting image sizes from 22" to 42" inches.
