Interestingly, there are more use cases for hysteresis in UI design, e.g. it was famously used in nested menus in Windows: https://www.mackido.com/Interface/hysteresis.html

I think there was also an article about it on The Old New Thing, but I can't seem to find it anymore.

>> Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past.

How is this different from the observation that, say, a non-magnetic iron ball may have more than one possible velocity in a given gravitional field, depending on whether it was recently thrown upward or dropped from above?
