The fingers of thousands of people who created sketches of
Brad Pitt and Angelina Jolie on their iPhones can collectively guide and
correct the drawing strokes of subsequent touchscreen users in an application
created by researchers at Carnegie Mellon University and Microsoft Research.
The app compensates for the "fat finger" problem
associated with touchscreens, automatically correcting a person's drawing
strokes while preserving the user's artistic style. "Our goal was to make
it invisible to the user, so people wouldn't even be aware the correction is
taking place," said Alex Limpaecher, a Ph.D. student in Carnegie Mellon's
Computer Science Department.
