The invention is a transparent keyboard with translucent markings to show the functions of each key. It can rest over the screen of a computer, hand held device, smart phone or the like, without obstructing the screen or using it for marking the keys or reducing the size of the screen area that is used as a screen or monitor as against a keyboard. It can be made by translucent markings on existing touchscreen keyboards or a transparent layer over the touchscreen with translucent markings. It can be a transparent screen with programmable markings. It can be touch sensitive, yet use key layouts and sizes to prevent unintended key activation and ease multi finger typing. |
