[BlindMath] Electronics Code

Wed Mar 29 13:12:14 UTC 2017

Hi Lisa,

Are you able to advise the Unicode values of these fonts in your document?

Unicode does contain various symbols in the 33## range for example such as
㎾ (U+33BE) for Kilowatts.

It's early days in my research, but I'm wondering if this might be a way
forward since it provides a single character as opposed to lower case
letter k followed by upper case W ?

That way it would be obvious to a sighted reader, and correct braille could
be applied to translation.

George

That does help!  This particular text uses thestylized  letters in formulas
but regular print V, R, I if it is w/in the actual text.  Ohm is not an
issue, as there is a Braille equivalent.

Thanks!

It will be interesting to hear opinions of others on this list, but my
recommendation would be to use regular V and I for voltage, current
respectively and R for a resistor. The special fonts apparently used in
your book convey no special information. Regular fonts are frequently used
in physics texts. And authors differ on using upper vs lower case. There is
no fast and firm rule as far as I know.

Resistance units are ohms and are symbolically represented by an upper case
greek omega.

Does this help?

OK.  I am working on converting an Electronics textbook and it uses the
stylized "V", "E", "I" for the symbols for volt, amp, etc.  This particular
chart lists the quantity, symbol (stylized letter), unit of measurement and
the unit abbreviation (standard print letter and the Greek omega).  Trying
to figure out how to convey the difference in the print symbols in braille.

There is no special braille code for electronics symbols. The math is done
in whichever code the student uses or wants to learn. Schematic diagrams
usually have letter-number combinations representing the components, and a
parts list that spells out more particulars of these components. Blind
people who work in this field have wished for, and not always gotten, a
verbal description of a schematic diagram, described with some
understanding of the functioning of the circuit so that the description is
complete and covers the connections in a logical manner. It is a good idea
to learn what the schematic symbols look like when represented tactually,
but diagrams quickly become too complicated to reproduce as raised drawings.

Anyone know where I would find the braille code for electronics symbols?
