We propose a DIY process to produce customized paper keyboards with kinesthetic feedback that interact with touchscreens. The process is built using two techniques: kirigami and printable double-layered circuits. Our goal is to improve the extensibility and usability of various interfaces made with 2D paper substrates. First, Our kirigami structures provide kinesthetic sensations whose z-directional keystroke is comparable to that of traditional keyboards. In order to design keys with appropriate stroke and reaction force, we adopted the Rotational Erection System (RES). Second, printable double-layered circuits allow users to easily adjust input layouts. This easy-to-customize keyboard can be especially useful for those who have specific requirements for input devices.
