Aftertouch sensors detect whether the musician is continuing to exert pressure after the initial strike of the key. Some aftertouch sensors also measure that pressure's intensity. The aftertouch feature allows keyboard players to change the tone or sound of a note after it is struck, the way that singers, wind players, or bowed instrument ...
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored.
By determining the timing between the activation of the first and second switches, the velocity of a key press can be determined—greatly improving the performance dynamic of a keyboard. The second is that instruments with a matrix circuit can only play in a monophonic fashion without the addition of a diode for each key crossing. [ 2 ]
Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with n-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed.
The sensor tells enough about the distance of the keypress to allow the user to adjust the actuation point (key sensitivity). This adjustment can be done with the help of the bundled software and individually for each key, if so implemented. [9] A keyboard which utilizes these abilities include the Realforce RGB.
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]
GET statement to detect a key press. Line crunching – program lines do not require any spaces except between the line number and statement. Only supported variable types are character string, single precision floating point, and 16-bit signed integer (saves space in arrays, otherwise useless and slower than floating point, as all calculations ...
Scancodes on IBM PC compatible computer keyboards are sets of 1 to 3 bytes which are sent by the keyboard. Most character keys have a single byte scancode; keys that perform special functions have 2-byte or 3-byte scancodes, usually beginning with the byte (in hexadecimal) E0, E1, or E2.
