Method and system for directing a control action

1. 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.

2. The system of claim 1 , further comprising:

a memory for saving at least one profile; and

wherein a time of activating the behavior is limited by the time window.

3. The system of claim 1 , wherein the sensing unit captures at least one of a plurality of profiles corresponding to movements between the capturing of the first profile and the second profile, and saves at least one of the plurality of profiles to the memory.

4. The system of claim 1 , wherein the sensing unit identifies at least one of a continuous touchless movement, an accelerated touchless movement, a graduated touchless movement, and a stop touchless movement.

5. The system of claim 1 , wherein at least one profile further includes coordinate information comprising at least one of a relative displacement, a time of flight measurement, a zero crossing, an amplitude, or an actual position of the object.

6. The system of claim 1 , wherein the sensing device comprises at least one of an ultrasonic device, an optical device, an infrared device, and a laser.

7. The system of claim 1 , wherein the behavior constitutes a user interface behavior for directing a control, which comprises at least one of a single click, a double click, a scroll, a left click, a middle click, a right click, or a hold.

8. The system of claim 1 , wherein the activating corresponds to a user interface behavior that occurs at a location corresponding to the first touchless movement.

9. The system of claim 1 , wherein the object exhibits an acknowledgement behavior when a movement is detected that is a visual cue.

10. The system of claim 9 , wherein the acknowledgement behavior is one of at least a flashing object effect, a color change of the object, a fade of the object, a morphing of the object, and a spin of the object.
