Smartphone Screen that can Identify Fingernails and Knuckle Touch

London: A computer scientist has built a prototype smartphone that can differentiate between touches from the knuckle, fingertip and even fingernail.
Chris Harrison from Carnegie Mellon University in Pittsburg, Pennsylvania, modified a Samsung Galaxy S3 smartphone to run on his FingerSense software.
The modified Smartphone has a small vibration sensor that looks for the acoustic and vibrational differences between the three types of touch.
For example, a fingertip could help select an object while a knuckle tap could act like the right-click on a computer mouse and open up a submenu.
¡°A big problem with touchscreens right now is that they are very simplistic, relative to the capability of our hands,¡± Harrison said.
¡°We could do so much more,¡± he said.
He said that the sensor is a standard piece of electronics, which could be added to any Smartphone¡¯s main circuit board.
¡°The real magic is in the software, this artificial intelligence that lives in the heart of the phone,¡± he added.
He has launched a company called Qeexo to sell his creation.
