How does smart scroll work?

I'm curious to understand how smart scroll technology functions. Could you elaborate on the mechanism behind it? Does it utilize advanced algorithms to predict my scrolling behavior, or does it rely on sensors to detect my scrolling speed and adjust accordingly? I'm also interested in knowing if smart scroll is a feature that's available across different devices and platforms, or if it's specific to certain types of technology. Lastly, how does smart scroll enhance the user experience, and are there any potential drawbacks or limitations to its use?
