KirigamiKeyboard

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 key stroke 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.
