Home Row Key Strip for Touch Screens

摘要

A movable semi-rigid strip of depressible keys that overlays a touch screen in order to provide tactile home positions for the fingers. The home row key strip can be easily moved into place over the visual image of the home row when the touch screen's keyboard appears. Anti-slip material on the bottom surface of the key strip keeps it in place at the typist types. An alternate configuration provides tabs on the end of the key strip that create tension on the sides of the touch screen or tablet computer in order to keep the key strip in place over the home row, but allowing the strip to slide quickly to a border region. Other configurations for affixing the key strip include magnets, tracks on the sides of the touch screen, and hinged arms that allow the key strip to move quickly on and off the touch screen.
