Abstract
Methods and systems for processing an input are disclosed that detect a portion of a hand and/or other detectable object in a region of space monitored by a 3D sensor. The method further includes determining a zone corresponding to the region of space in which the portion of the hand or other detectable object was detected. Also, the method can include determining from the zone a correct way to interpret inputs made by a position, shape or a motion of the portion of the hand or other detectable object.
Claims15
A method of interacting with a machine using input gestures, the method comprising:
- sensing, using a 3D sensor, positional information of one or more fingers of a user in a region of space monitored by the 3D sensor;
- defining a first user-specific virtual plane in the space according to a sensed position of a first finger of the user;
- defining a second user-specific virtual plane in the space according to a sensed position of a second finger of the user;
- detecting, by the 3D sensor, a first finger state of the first finger relative to the first user-specific virtual plane, the first finger state being one of the first finger moving closer to or further away from the first user-specific virtual plane;
- detecting, by the 3D sensor, a second finger state of the second finger relative to the second user-specific virtual plane;
- interpreting the first finger state as a first input gesture command to interact with a first functionality of the machine;
- and
- interpreting the second finger state as a second input gesture command to interact with a second functionality of the machine.

A system for interacting with a machine using input gestures, including:
- an image-capture device including at least one camera;
- an image analyzer coupled to the at least one camera, the image analyzer being configured to:
- sense, using a 3D sensor, positional information of one or more fingers of a user in a region of space monitored by the 3D sensor;
- define a first user-specific virtual plane in the space according to a sensed position of a first finger of the user;
- defining a second user-specific virtual plane in the space according to a sensed position of a second finger of the user;
- detect a first finger state of the first finger relative to the first user-specific virtual plane, the first finger state being one of the first finger moving closer to or further away from the first user-specific virtual plane;
- detect a second finger state of the second finger relative to the second user-specific virtual plane;
- interpret the first finger state as a first input gesture command to interact with a first functionality of the machine;
- and
- interpret the second finger state as a second input gesture command to interact with a second functionality of the machine.

A non-transitory computer-readable storage medium storing instructions for interacting with a machine using input gestures, the instructions, when executed by a processor, cause the processor to:
- sense, using a 3D sensor, positional information of one or more fingers of a user in a region of space monitored by the 3D sensor;
- define a first user-specific virtual plane in the space according to a sensed position of a first finger of the user;
- defining a second user-specific virtual plane in the space according to a sensed position of a second finger of the user;
- detect a first finger state of the first finger relative to the first user-specific virtual plane, the first finger state being one of the first finger moving closer to or further away from the first user-specific virtual plane;
- detect a second finger state of the second finger relative to the second user-specific virtual plane;
- interpret the first finger state as a first input gesture command to interact with a first functionality of the machine;
- and
- interpret the second finger state as a second input gesture command to interact with a second functionality of the machine.
