Touchscreens can start polishing their resumes now, because a touchless future is drawing closer for the next generation of smartphones. The ever-industrious Ishikawa Komuro Laboratory in Tokyo has enabled mobile devices to touchlessly recognize movements and gestures from user's fingers, according to Geek.com.
Fingerprinting with ink or even sensor plates poses a chore for everyone involved, except possibly 10-year-old kids. But that could change with a 3-D system that projects light patterns onto a finger and analyzes the image within a second.
The method works by beaming a series of striped lines so that they wrap around a finger. A 1.4 megapixel camera captures the lines at almost 1,000 pixels per inch, and creates a highly detailed 3-D map of the fingerprint ridges and valleys.
