Touch gesture indicating a scroll on a touch-sensitive display in a single direction

One or more computer-readable media storing instructions executable by a computing system, wherein the instructions recognize a touch gesture on a touch-sensitive display, comprising:

• categorizing a touch gesture as a flick gesture if it satisfies at least a first criterion;
• determining if the flick gesture satisfies a locking threshold in which the flick gesture remains within a threshold area on the display for a minimum travel distance and, if the locking threshold is satisfied, locking the flick gesture so that it causes content presented on the display to be scrolled in a single dimension;
• and
• if the flick gesture fails to satisfy the locking threshold, confirming that the touch gesture is a flick gesture if it satisfies at least a second criterion more stringent that the first criterion.

A computing device, comprising:

• a touch-sensitive display;
• a processor;
• and
• memory comprising code executable by the processor to:
• display a scrollable list of items on the touch-sensitive display;
• detect a first touch gesture over the scrollable list of items on the touch-sensitive display;
• classify the touch gesture as a flick gesture;
• if the flick gesture satisfies at least a first criterion reflecting a user intent to scroll the information elements in a single direction along a first of a pair of axes, lock a direction in which the information elements are scrolled along the single direction;
• and
• if the flick gesture satisfies the first criterion, undo any displacement of the information elements which has occurred along a second of the axes orthogonal to the first axis as a result of classifying the touch gesture as a flick gesture.
