People use touchscreen technology on computers when they use an ATM, receive boarding passes at the airport, or print pictures at a photo kiosk. And now Microsoft's new operating system for computers, Windows 7, has in-built ability to manipulate the display screen with one or more fingers and finger paint, play music, spin a globe or enlarge and rotate photos. Acer, Asus, Dell, Fujitsu, Gateway, Hewlett-Packard (HPQ), Lenovo, Sony, Toshiba and other PC makers have or will shortly trot out touch-ready computers with Windows 7.
The demand for touch-screen PCs is rising. Amy Leong, research director at the Gartner research firm, says the number of touch-screen PC units shipped will surpass 6 million in 2010, nearly quadrupling 2008 shipments. She says about 10% of the new PC models coming this year will support touch technology. According to iSuppli forecasts, the global market for touch-screens will reach $6.4 billion by 2013, up from $3.4 billion in 2008.
