In one embodiment, a computing device determines a size of a view port of a graphical user interface based on a scrolling frame rate, processing resources, or memory resources of the computing device. One or more content objects are displayed in the view port. A scroll region for the user to scroll within is determined and the scroll region is independent of the boundaries of the displayed content objects. A first touch gesture across one or more boundaries of the displayed content objects is received. A velocity of the first touch gesture motion is determined. When the velocity is less than or equal to a threshold velocity, the computing device scrolls to an adjacent content object of the current displayed content object. When the velocity is higher than the threshold velocity, the computing device scrolls to advance multiple content objects with respect to the current displayed content object.

Infinite bi-directional scrolling

In one embodiment, a method includes providing for display to a user content including multiple content objects that each has a boundary defining a two-dimensional area. A two-dimensional scroll region for user scrolling within the content is determined. The two-dimensional scroll region is independent of the two-dimensional areas of the content objects. User input to scroll within the content in one or both of the two dimensions across one or more of the boundaries is received. The method includes scrolling within the content according to the user input, the scrolling being continuous across the boundaries.
