HP-150 (aka HP Touchscreen or HP 45611A) was a compact, powerful and innovative computer made by Hewlett-Packard and introduced in Las Vegas at Comdex fall trade show on November 28,1983. It was based on the Intel 8088 CPU and was one of the world's earliest commercialized touch screen computers. Like other "workalike" IBM PC clones of the time, despite running customized MS-DOS versions 2.01, 2.11 and 3.20, the machine was not IBM PC DOS compatible. Its 8088 CPU, rated at 8 MHz, was faster than the 4.77 MHz CPUs used by the IBM PC of that period. Using add-on cards, main memory

A dual-touchscreen is a computer or phone display setup which uses two screens, either or both of which could be touch-capable, to display both elements of the computer's graphical user interface and virtualized implementations of common input devices, including virtual keyboards. Usually, in a dual-touchscreen computer or computing device, the most persistent GUI elements and functions are displayed on one, hand-accessible touchscreen (changing with the software application in use) alongside the virtual keyboard, while the other, more optically-centric display is used for those user interface

The Heliodisplay is an air-based display that uses water condensed from the air already present in the operating environment. The system, developed by IO2 Technology in 2001, uses a projection unit focused onto multiple layers of air and micron-sized atomized particles in midair, resulting in a two-dimensional display with no visible projection surface. This is similar in principle to the cinematic technique of rear projection. As dark areas of the image may appear invisible, the image may be more realistic than on a projection screen, although it is not volumetric. The system may be viewed fr
