Like, in the game where you can't control yourself, but the game controls it for you. Do those count as steps?
No, they do not.
I tested this by going to Hearthome City in Platinum, and talked to the Fisherman that leads you to the Contest Hall. I had the pedometer on in the Poketch, and the pedometer's number did not increase, hence my outcome. Did you care about what I just said then? x3
Hope I helped. :)
