Patent ID: 7847787

Claim:
A system for directing a touchless action, comprising a sensing unit for controlling a cursor responsive to tracking a first touchless movement of a finger directing the cursor to an object visually displayed at a first location in a user interface and capturing a first profile corresponding to the first touchless movement at the first location; a processor communicatively coupled to the sensing unit for comparing the first profile with a second profile captured during touchless tracking to a second location of the user interface and back to the first location, the second profile corresponding to a second touchless movement directing the cursor away and back again to the first location; a clock for limiting a time window between the comparing of the first profile and the comparing of the second profile, and a controller communicatively coupled to the device for activating a behavior on the object at the first location when the first profile and the second profile are substantially similar and occurring within the time window wherein at least one action on the object backtracks a movement of the cursor from a current location to a previous location, wherein the current location is the location of the cursor corresponding to the second touchless movement, the previous location is the location of the object corresponding to the first touchless movement.
