Abstract

A keyboard has a key array including keys, a top surface having a front edge and a back edge, and a bottom surface positioned opposite the top surface. An interface device for use with the keyboard includes a base, a front standoff coupled to the base and having a keyboard-contacting portion, and a back standoff coupled to the base and having a keyboard-contacting portion. The keyboard-contacting portions are spaced such that, when the base is positioned over the key array, the key array is positioned between the keyboard-contacting portions so as to align the base in a front-to-back orientation relative to the key array. The keyboard-contacting portions are both supported by the top surface of the keyboard. The interface device also includes a key-contacting mechanism mounted on the base in a fixed orientation relative to the standoffs, and a coupling mechanism for removably coupling the interface device to the keyboard.
