Tokyo University’s Touchless Pointing System Could Wipe Out Smudgy Screens

No Touchy, No Smudgy
Touchscreens are wondrous things, but nobody likes smudges, and attempts to magically prevent oil from sticking haven’t always found success. The proper solution might not be in fancy screen coatings but rather in removing the touchability together. Tokyo University has developed a system that uses a high-res camera to identify where a finger is in 3D space, so moving around and even air-clicking is detected. Multitouch seems to be right out at this point, and while the video after the break shows some rather deft looking typing on a dinky virtual keyboard, we’re not entirely convinced that this is the most enjoyable or ergonomic way to interact with a cellphone…

New Touchless 3D Fingerprinting System


Lines of light are projected on a finger to illuminate the print. The light is warped by the ridges and valleys of the fingertip, allowing researchers to generate a 3-D fingerprint.

A new non-contact, 3-D fingerprinting system could make spotting the bad guys faster and easier, whether it’s at the border or the police precinct. By projecting patterns of light onto a finger and analyzing the image, researchers from the University of Kentucky are able to create a more accurate print than those made with ink or sensor plates. The researchers say the system is more efficient than traditional fingerprinting and significantly reduces the number of incorrect matches.
