Kinds of Ergonomic Keyboards

Hi, does anyone have any idea what are the kinds of ergonomic keyboards?


Here are the kinds of keyboards:
– a roll-up keyboard that’s easy to carry and easy to clean (QWERTY)
– a laser projection keyboard that turns any flat surface into a QWERTY layout
– a wrist keyboard that has a miniature QWERTY setup (not for touch typing, though)
– a radial keyboard that scrambles the keys out of QWERTY order (still in development)
– a keyboard that eliminates keys entirely
