Abstract: A system, method, and computer-readable medium are disclosed for facilitating user interaction with a mobile device. A first control function is associated with a first user control located in a first location on the bezel of a mobile device to establish a target operational position for any user control that is subsequently associated with the control function. When the orientation of the mobile device is changed, the first control function is associated with a second user control, located in a second location on the bezel, to maintain the target operational position of the user control associated with the control function.
