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.
Claims18
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 captured images;
- 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 the amount of curvature of the path of movement based upon a maximum distance the path of movement is from a straight line between a staring point and ending point of the path of movement;
- and
- upon determining the intent of the user to change modes of operation, interpreting user gestures in accordance with a second mode of operation.
