Touch screens with feeling
Willie D. Jones · IEEE Spectrum · 2009
One of the most sought after new features on mobile devices is the touch screen. But that name is a misnomer, according to a group of researchers at Northwestern University, in Evanston, Ill., who point out the obvious-that these displays offer minimal tactile feedback. But suppose touch screens could touch you back: You could "feel," say, the edges of the buttons on a virtual keypad or the links on a Web page.
