I think what you're describing is the observer effect[1], not Heisenberg uncertainty[2]. Heisenberg uncertainty is much stronger than not being able to observe a system without disturbing it. It's more like, at a physical level, making the probability distribution of a position tight makes the distribution of momentum wide.
