Interestingly, Braille can be used in many different ways. For example, part of OGN uses hand Braille. There are two types: one-handed and two-handed. In the former, two fingers of the person receiving the message become a matrix on which the other person transmits words by touching the appropriate points. The fingers of the hand are naturally divided into three areas – at the fingertip, in the middle and at the palm, the so-called phalanges. The two fingers, the index and middle fingers, therefore have 6 areas on which the six-point Braille alphabet can be encoded.
The two-handed alphabet is based on the use of a Braille typewriter. The person receiving the message spreads their two hands, and the person sending the message ‘writes’ on their fingers as if they were typing on a keyboard. The Braille keyboard also has 6 basic keys, which, when pressed in a specific combination, allow you to write in six dots.
