Abstract
Methods and apparatus include determine velocity of a detected presence in a first direction relative to a capacitive sensing surface, during a period of time, and determine velocity of the detected presence in a second direction relative to the capacitive sensing surface, during the period of time. Methods and apparatus detect a change in the determined velocity in the first direction at a first time, detect a change in the determined velocity in the second direction at a second time; and recognize a user command based on a difference between the first time and the second time.
