Patent Images

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.
