The latest of the Economist’s Technology Quarterly has a survey of the history and state of touch technology.
“The double click does not translate terribly well to touch screens, however. This has led some researchers to look for alternatives. In developing his multi-touch screen, Dr Han found that there can be more to touch input than simply detecting contact. He has found a way to determine how much pressure is being applied. Adding a thin polymer layer, scored with microscopic ridges, to his touch screens causes the bright spot created by a finger touching the screen to vary in size and brightness depending on the pressure. This makes it possible, for example, to drag an item on the screen and then, by pushing harder, to slide it under another item. ”
