Hi, thank you for your great work.
I have a question regarding how scroll directions are defined in the dataset.
In the paper, it's mentioned that scroll actions are labeled as:
SCROLL [DIRECTION (UP/DOWN/LEFT/RIGHT)]
It also seems that both traditional scroll (vertical movement) and swipe (horizontal movement) gestures are unified under this SCROLL action type.
However, the labeling standard for direction is not fully clear, specifically:
Are directions based on finger movement or screen movement?
For example, does SCROLL DOWN mean the finger moved up (so the screen moved down)?
Or is it the opposite?
We couldn’t find an explicit explanation of this in the paper or preprocessing scripts. If there is a standard or reference implementation that defines how these directions are derived from gesture coordinates (e.g., start and end points), it would be very helpful to know.
Thanks in advance!
