Braille Quiz (Letter to Dots)
Welcome to this Braille quiz. This quiz is aimed at
checking your understanding of the cell assignments
for different characters. We have assumed that you have
gone through the tutorial pages
discussing the principles
of standard Braille applicable to English. There is also
a reverse quiz
in which a given dot pattern will
have to be identified as a specific letter or a text
Here you have to mark the dots corresponding to the character
that will be presented to you. This character (or string) will
be one of 63 different strings which include the letters
of the alphabet, punctuation and frequently used letter
combinations. By "string" we mean the text representation
corresponding to a braille cell. Reference to the text strings
is given in the tutorial mentioned above.
A Braille Cell with six dots will be shown as checkboxes and you
can use your mouse to check a box to mark a dot. A checked box may also
When you submit your answer, a results page will be displayed
indicating the correctness of your answer. The results page will
also display a new character.
The characters are chosen at random
and will not appear in any predictable order. It is possible
that you might see a character repeated occasionally. Mark the dots corresponding to "u"
Given below is an input facility to specify a Braille Cell, i.e., mark
one or more dots within the six dot cell. The cell is displayed
using six checkboxes arranged in three rows of two boxes each.
The mouse can be used to check a box. The TAB key on the keyboard
may also be used to locate a box and the checking done with
the space bar.
See if you can identify the dots corresponding to the letter, punctuation
mark or text string shown above. Checking a box is equivalent to putting a dot in the
associated box. You can uncheck a box as well. Please note that many cells
(Braille codes specified in terms of dots) stand for not just one letter
but an often used string of letters such as "and, ing , ff" etc. Also,
some of the cells may have multiple strings assigned to them. In such cases,
the string shown above will have a vertical bar between the alternatives.
In the quiz, the name of the letter of the alphabet, a punctuation or
a cell used for specifying a contraction will be shown. The name shown
may not follow any standard except that it may conform to an accepted
convention. Please refer to the chart provided in the tutorial on
standard English Braille to get to know the names that go with the cells.
