The next page shows the main AlphaTapp matrix. It shows the layout for both right and left hands. Line up the fingers with the matching columns to determine which fingers should be touching the surface to denote that element.
Print and turn the form to use whichever side is easiest for you, whether sending or receiving.
In the graph you can compare how the symbols appear when sending or receiving. The fingers in the diagram line up with the columns that show the dark boxes when that finger is touching. A clear block indicates a finger that is raised. (i.e., the letter A is thumb only, letter U is thumb and little finger, etc.)
Place your hand with all fingertips near the tapping surface. Starting with the thumb as A, a black box means that finger is making contact with the surface. All five fingers touching the surface is an E.
The numeric symbols duplicate of some of the alphabetic symbols. This is necessary as there are not enough combinations of five elements (fingers) to add ten additional symbols. Therefore the number/alpha symbol (index, ring) is used to tell your partner that you are switching between alphabetic and numeric (like the NUM LOCK key on a keyboard). A hand swipe (no fingers) denotes a space. A double hand-swipe can denote an error or backspace. A closed fist ends a sentence, or denotes a decimal point when in numeric mode.
