TapSense By Carnegie Mellon Recognizes Finger Parts Touching The Screen

Researchers at #-Link-Snipped-# know that your fingers aren't exactly made for the touchscreen of your phone. The problem with smaller touch screen is that they can't offer bigger menus & options to users because of the limited real estate. The solution to this problem has been developed by researchers ar Carnegie Mellon and they're calling it 'TapSense'. This new technology can effectively and accurately identify which part of your finger is touching the screen - and then perform actions accordingly. The technology identifies and analyses the sound produced by objects hitting the touchscreen. That is when you touch the screen with your nail or knuckle, different types of sounds are produced. A microphone cheaply available in the market is used to capture this sound and signal the installed software. As of now, the microphones inside the mobile devices can't capture this sound. Depending upon the type of sound received; the software can perform specific operations.

Researchers demonstrated possible uses of this technology in email applications. If you touch the screen with your knuckle, the app opens up email menu and if you touch it with your nail, it can take you to different menu; thus you can quickly access different options in any app by just touching the screen with a different finger part. We can clearly see that this technology will be heavily used in games designed for smartphones and tablets. Check out the following video demo -
