Minuum: Type Anywhere, Even Your Arm

As most on-screen is taking up a large space of the screen, the Minuum keyboard was introduced to eliminates the visual clutter of archaic mobile keyboards by adapting the keyboard to a single dimension. According to the inventor, “The Minuum layout is simply a continuum of letters, laid out in a row. We call it ‘one-dimensional’ because it’s based on one row of keys. This frees up the keyboard to be anywhere you like on the screen, or even to curve for a more ergonomic keyboard shape.”
