The Tap Strap is a keyboard that uses chords to register text. You type characters and commands by tapping a combination of fingers on any surface. Tap has accelerometers built into each finger-ring, which collect motion and acceleration information from your fingers. The output character is then transmitted via Bluetooth to the paired device. The Tap Strap is also an easy to use mouse. When you place your thumb down on a surface, Tap automatically turns into a mouse. You move the cursor with small movements of your thumb and control the mouse clicks with finger Taps. For example, to LEFT CLICK, you Tap your index finger, and to RIGHT CLICK, you Tap your middle finger. When you lift your hand from the surface, Tap Strap automatically turns back into a keyboard for a seamless transition.
Tap Strap can be worn on either your left or right hand. For best results, it is recommended that you learn to Tap with your dominant hand – once you learn the alphabet, you can Tap with either hand without having to re-learn it. The Tap Strap is completely portable, can fit in your pocket, and allows for full access to a keyboard and mouse in virtually all situations.
