Split control focus during a sustained user interaction

Abstract

The technology described herein splits the control focus of a user interface during a sustained user interaction. A sustained user interaction is an interaction action lasting more than a threshold period of time. The sustained interaction is initiated when the user directs the control focus of an interface onto an interface object and begins an interaction with the object. Upon determining that a sustained interaction has begun, a control focus lock is executed at the point of control focus where the sustained interaction began, for example, the point where the cursor was located when the sustained interaction began. Upon termination of the sustained interaction, the primary control focus is snapped to the location of the secondary control focus and a secondary control focus is terminated until a subsequent sustained interaction is detected.
