Keystroke dynamics, keystroke biometrics, typing dynamics, or typing biometrics refer to the collection of biometric information generated by key-press-related events that occur when a user types on a keyboard. [1] Use of patterns in key operation to identify operators predates modern computing, [2] and has been proposed as an authentication ...

Keyboards that lack full rollover will register an incorrect keystroke ...
The idea is to only use one hand (preferably the left one) and type the right-hand letters by holding a key which acts as a modifier key.The layout is mirrored, so the use of the muscle memory of the other hand is possible, which greatly reduces the amount of time needed to learn the layout, if the person previously used both hands to type.

The game begins with a tutorial on where to place fingers, and then with nonsense words like "assa" and "saas", with players soon progressing to complete sentences. [3] The CD-ROM came with a hardcover binder with details of each typing lesson for teachers. The game emphasizes the importance of posture and finger positioning for typing. [4]
A projection keyboard. A projection keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a surface: when a user touches the surface covered by an image of a key, the device records the corresponding keystroke.
