Wearable keyboard that turns anything you can touch into a typing surface

How It Works

The Tap Strap has a series of embedded sensors which monitor mechanical information
of the hand and fingers. This information is processed by an MCU in the Strap,
which decodes the raw data into finger tap combinations and transmits
the resulting characters or commands via a Bluetooth radio.
