Your touchscreen will soon distinguish between a finger, fingernail and a knuckle

Your touchscreen will soon distinguish between a finger, fingernail and a knuckle
Imagine being able to call up different features on your touchscreen phone depending on whether you used your finger, fingernail or knuckle on the screen. This is not as far away as you might think. Chris Harrison, a computer scientist at Carnegie Mellon University, has modified a Samsung Galaxy S III to distinguish the difference in touch input between a finger, fingernail and a knuckle.

The modded Samsung Galaxy S III has a small vibration sensor and when combined with Harrison's FingerSense software, the sensor can tell the difference between the three touch inputs based on vibrations and acoustics. A finger tip could let you select an object from the screen while a knuckle tap could act like a right-click on a mouse and show a sub-menu.

Harrison has started a company called Qeexo to sell the device and he says that the sensor can be added to the main circuit board of any smartphone. Harrison says he is in talks with major smartphone manufacturers now to bring this technology to the public. Harrison, though, says "the real magic is in the software, this artificial intelligence that lives in the heart of the phone".

Atleast we can look forward to a little piece of innovation then :) the fact that they are testing this on an S3 could mean the S4 may get it

Every time I think they ran out of ideas to put on phones, is the time they created something new. Good job, technology just gets better and better.

this is nothing new, if you ever worked in a office, the multifuction machines have very nice touch screens that responds to your finger, or a stylus or your finger nail, this is nothing new, its been in use for years now.. and a few of the cell phones already had this,, example the palm centro as well as a few other palm phones already had it,,,,, but it sure would like to see it on most of todays phones,,

Hmmm. Knuckle, nail, finger. You've got the makings of a great adult app right there. Seriously, even if it could eliminate/ignore random screen touches that'd be a great advance.

Why use your knuckle when you can use a banana or a fork? - Lumia 920. Lols

I don't think most of youse understand this article. It's not just detection of fingernails and knuckles, it is able to distinguish them, thus for example, you can make fingernail touches as hover, knuckle touches as right clicks etc.

Great app, quite impressive. This is a great idea for the women out there, my mother for one has longer nails and she keeps her older phone because it recognizes touch from what ever source. Vs the higher stuff of the current market which is heat sensitive so you have to use your knuckle or finger. Thats why I directed her to the note series and she is looking to go in that route. But this is a great idea for everyone. being able to have your menu button on any screen by simply throwing a knuckle is great! Among other possibilities.
