I think most of us are familiar with the interaction of holding onto a button and watching a particular value increment or cycle through at a constant speed.
However, I think it is common practice for many devices and applications these days to also incorporate a secondary interaction when you hold onto a button, which is to speed up when you hold onto it for a set amount of time.
For example, the volume button or control when pressed once will increment the value by one. When you press and hold for over a set amount of time (e.g. 1 second) then the value will increase much faster in a shorter period of time.
What is the term used to describe this design pattern or interaction? Are there other variations of this interaction that exists (i.e. other than just speeding up)?
