In computer keyboards, operator feedback provides the operator with one or more indications that keystrokes have been registered.
Audible feedback[edit | edit source]
Audible feedback uses sound to indicate successful detection of keystrokes. The most common form of audible feedback is that of a click mechanism inside each keyswitch. When the key actuates, a click sound is generated within the switch.
Alternatively, a device external to the switches can be provided. The most common choices are that of a buzzer or loudspeaker, and of a solenoid. In the case of solenoids, the solenoid is not used for its original electromechanical purpose, but simply as a way to generate a short, distinct sound. The Zenith ZKB-2 is an example of a keyboard that uses a buzzer, while solenoids can be found in some IBM Beam Spring Keyboards.
Tactile feedback[edit | edit source]
A tactile keyboard is one in which the operator is able to feel when keystrokes have registered.
