The designers of this keyboard concept have claimed the design is for you to bring your own keyboard along to avoid infections when using other computers. While that’s a noble pursuit (and possibly overkill- just bring a wipe to swipe down the keyboard instead), the result is a great conceptual design for a keyboard that folds up like a fan. Unlike say a silicon roll-up keyboard, this one maintains the rigidity you’re used to for typing. Good idea, I can definitely see it being produced.
