April fools or not, if we're talking alternative fast input methods then why not remind people of chording keyboards[1]? Nice simple keypads ergonomically designed for comfortable one handed use with multi key combinations corresponding to letters / digits / symbols.
There was a trial a few years back by the University of Queensland marine division of an underwater system with HUD facemask display and a chording keypad so that researchers diving could hold specimans / tools whilst also looking up references / enter data.
Like a number of alternative key entry systems it was surprisingly fast once people became used to it.
