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 string.

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 be unchecked. 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.
