Abstract: Keyboards and other input devices are provided with at least one flexible layer that extends over or under the keycaps. The flexible layer spans interkey spaces and provides finger support and key definition as the user feels the top surface of the keycaps and flexible layer. The flexible layer therefore smooths the top surface of the keyboard, supports fingers during key travel, prevents ingress of contaminants, fluids, or debris into the keyboard, and provides a surface that can be used as a touch interface that coincides with the keyboard.
