A keyboard overlay for use on a touch screen is disclosed, as well as novel key structures for use on overlays. The keyboard overlay and key structures have novel structures which can provide finger resting resistance, deceleration during actuation, pre-actuation cues, finger positioning cues, key identification cues, and other desired aspects of a keyboard optimized for touch typing. Methods for stowing and deploying the keyboard overlay to align with the virtual keyboard of a touch screen are also disclosed. The disclosed keyboard overlay can provide optimal touch typing characteristics for use on all known types of touch screens. |
