[BlindMath] Sharing a tic-tac-toe board description over the computer to another blind individual

[Sabra Ewing]

Makes no sense to me. Just use a spreadsheet or a table.

>> Multi-line braille should offer a more natural way to review board information for tic-tac-toe, checkers, chess, and other board games but only if we tell the blindness vendors what works best for blind users.

>> With speech it might be easier to examine a board skipping the "l" and "-" symbols and using "b" to indicate a blank grid location.

>> x b x
>> b o b
>> x b o

>> A tic-tac-toe board including piece locations might display nicely using a table in Microsoft Word.
>> You will notice that in the two examples above the braille is in 8-dot braille. For it to be in UEB or Nemeth braille code or literary braille the "x" and the "o" symbol might each require a letter sign before it making the symbol take up 2 braille cells.
>> I would be glad to hear your thoughts on these topics.
>> Very best,
