The case for a touchless, signless world.

A short essay on why interactive systems shouldn't assume you can speak — and what we've been quietly building for the body that's actually in the room.

• The premise. Most technology around us assumes you can speak. That fails a much bigger group than people usually imagine.
• By the numbers. 7.5M Americans can't easily use their voices. 36 handshapes cover the alphabet. ~5B cameras are already deployed. Zero new science required.
• What designing for it looks like. A keypad you sign at. A drive-thru that responds to a thumb. A museum guestbook that prints your name ten feet tall.
• Where we come in. Hardware, firmware, gameplay, set design — built end to end in Frederick. Built once, run for years.
