I often wondered why simple CAPTCHA's like "Type the number seven four three", or "What is the sum of two plus three?", or "Spell cat", or "Spell two" wouldn't work? Certainly, one can create a routine coupled a dB to randomly produce thousands of different combinations of simple questions. Likewise, a sound file could be produced the same way.

This could get hard for people, not everybody does understand a lot of English. So if you're asking a question, it does also get harder for some humans and that's not what we are looking for. Tijnema

That's a good point. Not only should a captcha be accessible by sighted, visually impaired, deaf-blind, cognitive impaired, and other disabilities not mentioned, but also deal with all languages as well. It certainly sounds impossible, but what are the commonalities of the above groups? Clearly specific languages won't work. However, similar problems arose in maritime and aviation industries where different nationality captains were/are required to know specific "English" words to pilot globally. So, the net may present some words that should be recognized by all, but that's not up to me, but rather to the consensuses of the net to develop. For example, perhaps "About" and "Home" may be good candidates, if yo see what I mean. If not language, what? Mathematical symbols, Dingbats, Miscellaneous symbols, General Punctuation from the Unicode dB may be candidates for a more universal basis for communication. But how does one convey that information to everyone? Hell, some current browsers still can't render Unicode correctly in the url's, let alone a way to "show" them to screen readers. In addition, even OS's make it hard for user to even enter/use those type of characters (except for Mac of course). There has to be some commonality -- any suggestions?
