Abstract: The disclosed technology includes using horizontal components and vertical components of a velocity vector associated with movement of an input gesture to determine a user's intended, dominant direction of movement and corresponding control function at various points during the input gesture. Thresholds may be dynamically adjusted to prevent a user from unintentionally changing control functions during the input gesture. By adjusting the sensitivity associated with changes in a direction of movement of a continuous input gesture, it can be made effectively more difficult for the user to unintentionally cause a change in control functions. In example implementations, one or more thresholds associated with changing a control function may be increased or decreased during a continuous input gesture. For example, the thresholds may be increased or decreased in proportion to an increase or decrease in a velocity vector component.
