Abstract: The technology disclosed relates to distinguishing meaningful gestures from proximate non-meaningful gestures in a three-dimensional (3D) sensory space. In particular, it relates to calculating spatial trajectories of different gestures and determining a dominant gesture based on magnitudes of the spatial trajectories. The technology disclosed also relates to uniformly responding to gestural inputs from a user irrespective of a position of the user. In particular, it relates to automatically adapting a responsiveness scale between gestures in a physical space and resulting responses in a gestural interface by automatically proportioning on-screen responsiveness to scaled movement distances of gestures in the physical space, user spacing with the 3D sensory space, or virtual object density in the gestural interface. The technology disclosed further relates to detecting if a user has intended to interact with a virtual object based on measuring a degree of completion of gestures and creating interface elements in the 3D space.

Abstract: The technology disclosed relates to determining intent for the interaction by calculating a center of effort for the applied forces. Movement of the points of virtual contacts and the center of effort are then monitored to determine a gesture-type intended for the interaction. The number of points of virtual contacts of the feeler zones and proximities between the points of virtual contacts are used to determine a degree of precision of a control object-gesture.

Abstract: The technology disclosed relates to automatically interpreting a gesture of a control object in a three dimensional sensor space by sensing a movement of the control object in the three dimensional sensor space, sensing orientation of the control object, defining a control plane tangential to a surface of the control object and interpreting the gesture based on whether the movement of the control object is more normal to the control plane or more parallel to the control plane.

Abstract: Free space machine interface and control can be facilitated by predictive entities useful in interpreting a control object's position and/or motion (including objects having one or more articulating members, i.e., humans and/or animals and/or machines). Predictive entities can be driven using motion information captured using image information or the equivalents. Predictive information can be improved applying techniques for correlating with information from observations.

Abstract: A method for detecting a finger is provided. The method includes obtaining a plurality of digital images including a first digital image captured by a camera from a field of view containing a background and a hand including at least one finger, and obtaining an identification of pixels of the plurality of digital images that correspond to at least one finger that is visible in the plurality of digital images rather than to the background, the pixels being identified by: obtaining, from the digital images, a Gaussian brightness falloff pattern indicative of at least one finger, identifying an axis of the at least one finger based on the obtained Gaussian brightness falloff pattern indicative of the at least one finger without identifying edges of the at least one finger, and identifying the pixels that correspond to the at least one finger based on the identified axis.

Abstract: The technology disclosed relates to a method of realistic displacement of a virtual object for an interaction between a control object in a three-dimensional (3D) sensory space and the virtual object in a virtual space that the control object interacts with. In particular, it relates to detecting free-form gestures of a control object in a three-dimensional (3D) sensory space and generating for display a 3D solid control object model for the control object during the free-form gestures, including sub-components of the control object and in response to detecting a 2D sub-component free-form gesture of the control object in the 3D sensory space in virtual contact with the virtual object, depicting, in the generated display, the virtual contact and resulting rotation of the virtual object by the 3D solid control object model.

Abstract: Methods and systems for determining a gesture command from analysis of differences in positions of fit closed curves fit to observed edges of a control object to track motion of the control object while making a gesture in a 3D space include repeatedly obtaining captured images of a control object moving in 3D space and calculating observed edges of the control object from the captured images. Closed curves are fit to the observed edges of the control object, including control object appendages for multiple portions of any complex control objects, as captured in the captured images by selecting a closed curve from a family of similar closed curves that fit the observed edges of the control object as captured using an assumed parameter. Using fitted closed curves, a complex control object is constructed from multiple portions of any complex control objects and one or more of control object appendages appended.

Abstract: A motion sensory and imaging device capable of acquiring imaging information of the scene and providing at least a near real time pass-through of imaging information to a user. The sensory and imaging device can be used stand-alone or coupled to a wearable or portable device to create a wearable sensory system capable of presenting to the wearer the imaging information augmented with virtualized or created presentations of information.
