[Blindmath] producing Nemeth math as a blind person

Tue Nov 18 19:33:32 UTC 2008

A braille cell is made up of six dots; these six dots are arranged in two columns with three dots in each column.  The upper left dot is dot 1; left middle is dot 2; left bottom is dot 3; upper right is dot 4; right middle is dot 5; right bottom is dot 6.  These six dots correspond to a variety of manual and electronic note takers and braille writers.  The keys on the note takers and braille writers are generally arranged in two horizontal sets; we'll call set 1 on the left, and set 2 on the right.  Starting with the rightmost key in set 1, this key corresponds to dot 1.  The middle key in set 1 on the left side corresponds to dot 2; and the leftmost key in set 1 corresponds to dot 3.  Starting with the leftmost key in set 2, this key corresponds to dot 4.  The middle key in set 2 on the right corresponds to dot 5; and the rightmost key in set 2 corresponds to dot 6.  By pressing one or more of the six keys simultaneously, a person is able to produce readable braille or to take notes in braille.  There are also some QWERTY keyboards that have been programmed to accept 6-key entry, i.e. select letters or numbers have been mapped in such a way to correspond with braille dots 1 through 6.

I believe 6-key refers to the 6-key type keyboard found on Perkins Braillers
and many portable electronic notetakers. Instead of each key entering one
letter / number / symbol, you actually punch several keys to enter a given
symbol. The keys you press are the ones which form that symbol in braille,
so if the symbol is the  letter "d", you'd press keys 1, 4, and 5 on the
6-key keypad.

Hope that helps.

Can someone please explain what 6 key entry is? My son uses duxbury, not for
math as of yet because he still uses a perkins brallewriter but am unclear
what 6 key is.

Thanks

Darlene
