The computer also featured an Intel Core 2 Duo T5850 (2.16 GHz), 4GB of RAM, and a 23" glossed sensitive touchscreen with a 358MB Intel GMA Mobile 965 GPU (before late 2009) or a Nvidia 9600M GS (after late 2009). The HP Touchsmart 520 featured in the series was one of the more powerful units, with an Intel i3 processor, 4GB of RAM, and a 1TB ...
HP-150 II (aka HP 45849A) [6] replaced HP-150 in 1984. While still called HP Touchscreen II , the touchscreen was no longer standard, but rather a rarely adopted option. The optional touchscreen bezel was superior to the original bezel, in that the emitters and detectors were now located behind a solid infrared-transparent plastic; thus ...
A touch user interface (TUI) is a computer-pointing technology based upon the sense of touch ().Whereas a graphical user interface (GUI) relies upon the sense of sight, a TUI enables not only the sense of touch to innervate and activate computer-based functions, it also allows the user, particularly those with visual impairments, an added level of interaction based upon tactile or Braille input.
Guidelines for touchscreen designs were first developed in the 2000s, based on early research and actual use of older systems, typically using infrared grids—which were highly dependent on the size of the user's fingers. These guidelines are less relevant for the bulk of modern touch devices which use capacitive or resistive touch technology.
Sometimes RAM limits can be overcome using special techniques. Bank switching allows blocks of RAM memory to be switched into the processor's address space when required, under program control. Operating systems routinely manage running programs using virtual memory , where individual program operate as if they have access to a large memory ...
