Multi Touch Screen to Rise

Filed Under Consumer Electronics, Video Gallery | Leave a Comment

When Apple launched iPhone in June 2007, it indeed raised the bar for user interface in mobile phones and changed the rule of the game in consumer electronics. Apple iPhone’s mutli-touch screen user interface is so cool and captivating that it has catalyzed and spurred the accelerated adoption of multi-touch screen technology in consumer electronics markets, especially among the young people. Using intuitive and natural touch screen, keypads and buttons might soon be a thing in the past. Since the launch of iPhone, a couple of consumer electronics companies have introduced devices and gadgets with multi-touch screen feature. For examples, LG and Philips introduced a 52-inch multi-touch display during CeBit 2008. LG also launched a Window Mobile-based PDA phone,KS20, with multi touch screen feature. The market research company, iSuppli, predicts that global shipment revenue for leading touch-screen technologies will increase to $4.4 billion by 2012, up from $2.4 billion in 2006. Retail, kiosk, financial, e-book and medical applications are also adopting more touch-screen monitors to accommodate consumer preferences for intuitive and easy user interfaces, according to the study.

I did some googling on the history of mulit-touch technology. Multi-touch has a history beginning in 1982, with pioneering work being done at the University of Toronto (multi-touch tablets) and Bell Labs (multi-touch screens). Later, the University of Delaware developed a sophisticated two-handed typing and gesture recognition system in the late 1990s. The first commercially available display using multi-touch technology was the Lemur Input Device, a professional multi-media controller from the French company JazzMutant, launched in 2005. (Ref)
