Abstract:
1. A method for determining scroll direction intent, the method comprising: receiving a first ordered pair of coordinates of a scroll event and a second ordered pair of coordinates of the scroll event; determining a first area of a first region of a square that is divided into the first region and a second region by a line segment comprising endpoints of the first ordered pair of coordinates and the second ordered pair of coordinates, wherein the square comprises a first vertex at the first ordered pair of coordinates, a second vertex opposite to the first vertex at a third ordered pair of coordinates for which each coordinate has an absolute value that is equal to a maximum absolute coordinate value of the second ordered pair of coordinates, and a side that passes through the second ordered pair of coordinates; determining a second area of the second region of the square; determining, by a processor, an intended scroll direction of the scroll event based at least in part on the first area of the first region and the second area of the second region; and providing the intended scroll direction of the scroll event.
