"What we're going to see is the younger generation beginning to use touchscreen computers ahead of enterprises. We expect more than 50 per cent of PCs purchased for users under the age of 15 to have touchscreens, up from fewer than 2 per cent in 2009," said Leslie Fiering, research vice president at Gartner.
At the same time, she predicted that less than 10 per cent of PCs sold to enterprises in 2015 are going to have touchscreen. The release of smartphone like Apple iPhone and the very recent launch of iPad made touch screen based devices very popular across the users worldwide. Gartner further predicts that the smartphone users will want to extend their touch based experience in their PCs too.
Many enterprises use touch and pen for their vertical applications for field services, clipboard replacements etc. Touch is also being used by many information kiosks and automated teller machines (ATMs). This trend will grow further because hardware prices continue to drop and application software will become more sophisticated. Restaurants, retail and healthcare providers will adopt the touch screen devices early due to the nature of their services.
Additionally, Gartner thinks that consumers are going to adopt touch screen devices very quickly, the penetration of touch screen at Enterprise level will be slow. They also project that no particular application will capture the market all of a sudden. But there is going to be gradual introduction of user interfaces and increase in touch based software.
