Abstract
A novel keyless keyboard uses membrane switches or touch screen to generate keystroke signals, without traditional keycaps. The keyless keyboard can be folded to further reduce its size during storage. The keyless keyboard unfolds into a keyboard of normal desktop keyboard size for easy use. When touch screen is used, the keyboard is also a display screen.
