Input Acceptance Filtering slows down the response of the switch so that the user has to keep it continuously pressed for a certain time before the input is accepted and registered by the computer. This time period is called the input acceptance time. People with physical impairments
Input Acceptance filtering is useful for reducing the likelihood of accidental selections being made by a user with clumsy or uncoordinated movement. For example, switch users who cannot press the switch with a definite action but tend to hit it several times due to involuntary or uncoordinated movements; keyboard users who tend to ‘knock’ other keys when typing. (Note: for keyboard users, input filtering is often used in conjunction with a keyguard fitted over the keyboard.) The input acceptance time should be increased until the unintentional switch presses are no longer accepted by the computer. For |
