I propose that in certain dangerous situations, where serious system harm could be done, a new 'Interrupt Protective Quiz' subroutine be invoked:
A small task (interrupt protective quiz) that takes a moment of intentional and conscious thought. This would help to prevent tiredness, intoxication, and automatic/rote behaviors from leading to disaster. It would need enough randomness and non-repeatability to be effective, not memorized, simple enough that it does not become too high a barrier, but sufficiently challenging to interrupt the user to think about a pending action. These concepts cover some variety of method and also consider a user's ability:
- a word captcha of a sort that could work with the user's primary language, any random dictionary could work, and the obfuscation algorithm need not be excessive.
- primary color words colored in the wrong color with a timed answer to "what color is it?"- a series of three with a requirement of 2 correct answers.
- audio mildly munged, and require to type the word heard.
- count the number of a specific shape among a random assortment of simple shapes (square, circle, triangle) shown.
Whether success or failure of the above, the task at hand is restated, but only success
at the Interrupt Protective Quiz
will allow proceeding with the dangerous task, otherwise the quiz is repeated.
