That also what I thought, it doesn’t sound like a good RC in WILD conditions. Now it could perhaps be slightly modified. For instance, when you count 1, you imagine an object, and when you count 60, you try and remember what object you’ve thought about ? Just my two cents, I’ve never test this and I don’t have any better idea.
And what about performing simple arithmetics? Or possibly remembering an event of the day, instead of something which happened 5 minutes ago? Or a phone number?
