HVAC Control in the New Millenniummovement for certain types of user input. For safety reasons, outer peripheralvision would not be projected during use in an operationalenvironment.MHA TechnologyMagnetic haptic array (MHA) technology can provide tactile feedbackin almost any angle and position. MHA technology uses graviticforces rather than magnetism to produce force vectors on the user’shands and forearms. The magnetic in MHA refers to the use of weakmagnetic fields for position sensing.A pair of magnetically sensitive gloves allows the MHA to projectgravitic forces. The user would be able to perform mechanical procedureswith full tactile feedback on the hands and forearms.DisplaysNew technologies are also being developed to replace standard displayssuch as cathode-ray tubes (CRTs) and liquid crystal displays (LCDs)which may be bulky, or hard to see and consume too much power.IBM has developed a new flat-panel technology that provides fourtimes the resolution of Super XGA (1,280 x 1,024) which is the best LCDdisplay currently available. Instead of using the display materials of molybdenumand tungsten, these new displays use aluminum and copper,which are better conductors and provide higher resolution.The Roentgen 16.3-inch display has a resolution of 2,560 by 2,048pixels which is over 5 million pixels with 200 dots per inch. It will initiallybe available for medical imaging, but should soon find its way to laptops.Xerox PARC has been working on the ultra-thin Gyricon display,which uses millions of plastic balls enclosed in a pocket of oil within asheet of rubber. Each ball has a white half and a black half and carries anelectric charge. The black side creates black dots, and the white side createswhite dots, much the way photographs are displayed in a newspaper.The balls can be locked to provide long-term storage of an image.When the charge is changed, a new image appears. The resolution isabout 400 to 600 dpi, which is close to laser printer quality. Most desktop©2001 by The Fairmont Press, Inc. All rights reserved.
