1. A gesture-recognition system comprising:
- an image-capture device for obtaining digital images of an object in 3D space;
a processor-executable analysis module for computationally determining a path of movement of the object based on the digital images obtained;
a computer memory for storing a digital representation of the path of movement; and
a processor-executable mode-control module configured for;
interpreting user gestures in accordance with a first mode of operation;
analyzing the path of movement to determine an intent of a user to change modes of operation by;
determining whether the path of movement intersects a virtual reference plane; and
wherein the virtual reference plane is created based on analyzing a path of movement of a prior gesture to determine an intent of a user to create a virtual reference plane in making the prior gestures; and
upon determining the intent of the user to change modes of operation, interpreting user gestures in accordance with a second mode of operation.

Abstract
Methods and systems for processing input from an image-capture device for gesture-recognition. The method further includes computationally interpreting user gestures in accordance with a first mode of operation; analyzing the path of movement of an object to determine an intent of a user to change modes of operation; and, upon determining an intent of the user to change modes of operation, subsequently interpreting user gestures in accordance with the second mode of operation.
