Abstract
Keyboard systems and methods are provided herein. In one embodiment, an overlay keyboard for touch screen devices includes a physical keyboard that can be mounted onto a touch screen device (e.g., a corded touch screen device or a touch screen mobile device) that provides a virtual keyboard (e.g., a software displayed touch screen), in which the physical keyboard can be overlaid onto the virtual keyboard of the touch screen device. When no key of the physical keyboard is pressed down, the physical keyboard does not trigger the touch screen of the touch screen device. When a key of the physical keyboard is pressed down, the physical keyboard touches the touch screen on a corresponding key of the virtual keyboard on the touch screen device, thereby causing the touch screen to detect that the corresponding key of the virtual keyboard has been pressed.
