Researchers have developed a non-mechanical intelligent keyboard that could increase security for computer users based on keystrokes, typing habit, and finger size

Researchers at the Georgia Institute of Technology have developed a biometric keyboard that can recognize and grant access to users based on their unique typing patterns.

The keyboard analyzes different parameters, including the force applied when pressing the keys and the time interval between each keystroke. The self-powered non-mechanical device holds promise for increased computer security, providing a new biometric for protecting machines from unauthorized use.

The intelligent keyboard is made up of vertically-stacked transparent film materials instead of individual mechanical keys. It generates electricity when a user's fingertips make contact with the multi-layer plastic materials, interacting to close a circuit. The output, which is evaluated, is unique to individuals depending on factors such as the rhythm of keystrokes, typing habit, finger size, bioelectricity, and the typing force applied.
