Door lock user interface

A user interface method for an automated door lock, including providing a sensor operable to identify two-dimensional locations of an object within a detection plane that extends outward from a door, providing an unlocker operative to automatically unlock the door, identifying, by a processor coupled with the sensor and the unlocker, a linear movement of the object within the detection plane, in a first direction of motion, further identifying, by the processor, a linear movement of the object within the detection plane, in a second direction of motion substantially orthogonal to the first direction of motion, and activating, by the processor, the unlocker in response to the identifying and the further identifying.
