How Does Tap Work?
Tap is a virtual input device that uses chords to register text. There are no keys involved at all – no projected keyboard, no invisible key patterns and no holograms. You type characters and commands by tapping a combination of fingers on any surface. The Tap Strap has accelerometers built into each finger-ring, which collect motion and acceleration information from your fingers. That information is analyzed by a small computer chip, which is built into the thumb ring. The output character is then transmitted via Bluetooth to the paired device.
The tapping motion is similar to playing a piano. Some characters – the vowels – require only one finger, while others require multiple fingers to tap at the same time. For example, the most common consonants, N, T, L and S, are tapped with two adjacent fingers. “N” is the thumb and index finger, “T” is the index and middle finger, “L” is the middle and ring finger, and “S” is the ring and pinky.
So, to spell the word, “INTO”, you would tap the following sequence:
I = Middle Finger
N = Thumb+Index
T = Index+Middle
O = Ring Finger
