An anonymous reader writes "A paper was recently published about Shift at the Computer Human Interaction Conference earlier this month. The authors (Daniel Vogel, a Ph.D. candidate at the University of Toronto and Patrick Baudisch, a research scientist at Microsoft Research) developed the technology to solve several problems with mobile-phone touch screens. Most such screens are designed to be operated with a stylus; when touched with a finger the UI doesn't work so well. They also created a short video with a demonstration of how Shift works. Shift builds on an existing technology known as Offset Cursor, which displays a cursor just above the spot a user touches on the screen. That allows a user to place their finger below the item they wish to choose so that they can see the item, rather than hiding it with their finger."
