Researchers have begun to focus on this facet of mobile phones. Last week, for example, computer scientists at Georgia Tech showed how placing a phone on a desk could allow its accelerometer to detect the vibrations from key presses on a nearby keyboard and pick out words with an accuracy of up to 80 percent.
