The Quadoo Alphabet (cc)

Quadoo Alphabet
Quadoo [phonetic notation kwa-Doh: kwɑ ˈdoː], the square writing by Alexander Fakoó

The Quadoo Alphabet (the Quadoo Writing) as square braille or square writing for the blind (also called line alphabet, square script or square scripture) was developed for handwritten notes by the blind. In this case, a hole slate is used with square holes and written only with six lines side correctly.

Quadoo is a relief writing and as a curveless blind handwriting also an alternative for touch and / or learning impaired blind. Other blind people can use this for quick notes too. The Quadoo Alphabet can also be used outdoor as a makeshift writing (new window). Because only vertical, horizontal and diagonal lines form the characters.

    ---------- Quadoo Alphabet: ----------
    Only the four sidelines of a square and the two
    diagonals are used. To describe the lines, the
    four corner points are numbered as follows:
      top:  [1] [2]
      bottom: [3] [4]
    or the following abbreviations are used for the letter code:
      t = top,  b = bottom,
      r = right,  l = left,
      u = up,  d = down

    For each character the points are to
    be connected in the following order:
    A = 3-2-4         = ru
    B = 1-2-4-3-2     = trbu
    C = 4-3-2         = bu
    D = 3-2-4-3       = rbu
    E = 2-1-3-4       = tbl
    F = 2-1-3         = tl
    G = 2-1-4         = td
    H = 1-3 + 2-4     = rl
    I = 3-2           = u
    J = 2-4-3         = rb
    K = 1-3-4-3-2     = blu
    L = 1-3-4         = bl
    M = 4-2-1-3-2     = trlu
    N = 3-1-4-2       = rld
    O = 2-1-3-4-2     = trbl
    P = 3-1-2-3       = tlu
    Q = 1-2-4-3-1-4   = trbld
    R = 3-1-2-1-4     = tld
    S = 3-4-1         = bd
    T = 1-2-4         = tr
    U = 1-3-4-2       = rbl
    V = 1-3-2         = lu
    W = 1-3-4-2-3     = rblu
    X = 1-4 + 2-3     = ud
    Y = 2-4-3-4-1     = rbd
    Z = 1-2-3-4       = tbu

    1 = 2-4           = r
    2 = 1-2-4-3       = trb
    3 = 1-2-4-2-3     = tru
    4 = 4-1-2-3       = tsd
    5 = 2-1-4-3       = tbd

    7 = 1-2-3         = tu
    8 = 2-1-4-3-2-1   = tbud
    9 = 3-4-2-1-4     = trbd

For the Quadoo Alphabet, only the sides and diagonals of a square are used (two lines horizontally, two vertically and two diagonally) which makes it very easy to write with a stencil. There are no circles or arcs in the letters and numbers that the blind can only write inaccurately, only the punctuation marks contain dots.


Coding of the Quadoo lines in English (see Tooltip)     Coding of the Quadoo lines in German (see Tooltip)     Numbering of the lines: top = 1, right = 2, bottom = 3, left = 4, up = 5, down = 6

And best of all: Quadoo contains clearly defined numbers. All characters are derived from the black text, which gives a high re-recognition effect and makes it easier to read optically than Moon. If the size is right, Quadoo will feel good too.

Terzi Alphabet and Freemason Code



A similar alphabet like Qadoo with lines and dots had already been proposed in 1670 by the Italian Francesco Lana di Terzi (new window), but his alphabet was intended from the outset for the blind to hide secrets:

Helen Keller and her square script

Helen Keller used a square font other than Quadoo, in which the letters were written very square. Here first write attempts from 1887:

The problem with the question mark


The most difficult point in this writing is the question mark, because it should be detectable without confusion and must also satisfy tactile as well as optical requirements.

In the course of development different question marks were tested, but different requirements depending on the representation, the tactile and optical readability of the text and the restriction to the square of 6 lines and 5 dots, no variant is to be regarded as optimal.

possible 16 question mark variants: 1-2-3P4 / 2-1-4P3 / 1-4-2P3 / 1-3-2P4 / 3-1-2P4 / 1-2-4P3 / 3-1-2-4P5 / 1-2-4-3P5 / 1-2+3-4P5 / 1-3+2-4P5 / 3-4P5 / 3-2P4 / 1-2-3-4P4 / 1-3-2-4P4 / 1-2-3-1P4 / 1-2-4-1P3

The last choice fell on the unused character lines Linien 1-2-4-1, where a dot expansion was possible and which tactile is well detectable. In some representations of the alphabet is deviated from it.
