This product is a replacement of snellen projectors. It is used when you read the letters on the chart. There are key letters that are expected and others that are not allowed. Already the software must go through some basic checks.Mark, could you tie this into a spell checker's database? I presume spell checkers know how to spell bad words as well as good ones, so you could reject any word that is found in the database.
1. Certain letters must show up while others can not.
2. Letters are not allowed to repeat on a given line.
3. Lines must contain 5 letters (provided the given system can fit that many)
4. Lines must be completely random to prevent memorization (whether it is accidental or not)
5. New: no recognizable words can show up (bad or good)
I have found that using a large enough pre-done list that meets the qualifications above will do the job nicely.
Hi Sarah,
I used a spell checker list from an old MC spell checker program someone created. I also got an embarrassingly long list of other words from a helpful lister that I used to augment the spell checker list. If something can be found after all this work, I will shrug and say "wow....didn't know that one. " :)
