THE multi-touch technology that Apple pioneered with its iPhone is now everywhere in the modern world - but Microsoft is about to pump up the technology to a new level. The next generation of its 'Surface table is a 40-inch touchscreen that can feel 50 'touches at once - and can also 'feel pens, pointers or anything else placed on the table. Screens on gizmos such as iPhone can only feel fingers. The Full HD screen has a high-powered Windows PC built in - and is just four inches thick. The screen works by shining light upwards through the screen, which bounces back to a layer of sensors behind the screen. It can detect not only fingers but objects on the table - whereas other touchscreen technologies are limited in what they can detect. For instance, touching an iPhone screen with a pen will have no effect. MOL
