Abstract: The technology disclosed relates to the creation of a gesture library for subsequent use in filtering gestures. In particular, the methods disclosed here generate and store gestures and their characteristic values to create a set of user-defined reference gestures that can be compared against characteristics of actual gestures performed in a 3D sensory space. Based on these comparisons, a set of gestures of interest may be filtered from all the gestures performed in the 3D sensory space. The technology disclosed also relates to customizing gesture interpretation for a particular user, and to setting parameters for recognizing gestures by prompting the user to select values for characteristics of the gestures. In one implementation, the technology disclosed includes performing characteristic focused demonstrations of boundaries of the gesture. It further includes testing the interpretation of gestures by prompting the user to perform complete gesture demonstrations and receiving user evaluation regarding the interpretation.

Abstract: The technology disclosed can provide capabilities such as using motion sensors and/or other types of sensors coupled to a motion-capture system to monitor motions within a real environment. A virtual object can be projected to a user of a portable device integrated into an augmented rendering of a real environment about the user. Motion information of a user body portion is determined based at least in part upon sensory information received from imaging or acoustic sensory devices. Control information is communicated to a system based in part on a combination of the motion of the portable device and the detected motion of the user. The virtual device experience can be augmented in some implementations by the addition of haptic, audio and/or other sensory information projectors.

Abstract: Aspects of the systems and methods are described providing for modifying a presented interactive element or object, such as a cursor, based on user-input gestures, the presented environment of the cursor, or any combination thereof. The color, size, shape, transparency, and/or responsiveness of the cursor may change based on the gesture velocity, acceleration, or path. In one implementation, the cursor “stretches” to graphically indicate the velocity and/or acceleration of the gesture. The display properties of the cursor may also change if, for example, the area of the screen occupied by the cursor is dark, bright, textured, or is otherwise complicated. In another implementation, the cursor is drawn using sub-pixel smoothing to improve its visual quality.

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.

Abstract: The technology disclosed relates to enhancing the fields of view of one or more cameras of a gesture recognition system for augmenting the three-dimensional (3D) sensory space of the gesture recognition system. The augmented 3D sensory space allows for inclusion of previously uncaptured of regions and points for which gestures can be interpreted i.e. blind spots of the cameras of the gesture recognition system. Some examples of such blind spots include areas underneath the cameras and/or within 20-85 degrees of a tangential axis of the cameras. In particular, the technology disclosed uses a Fresnel prismatic element and/or a triangular prism element to redirect the optical axis of the cameras, giving the cameras fields of view that cover at least 45 to 80 degrees from tangential to the vertical axis of a display screen on which the cameras are mounted.

Abstract: The technology disclosed relates to simplifying updating of a predictive model using clustering observed points. In particular, it relates to observing a set of points in 3D sensory space, determining surface normal directions from the points, clustering the points by their surface normal directions and adjacency, accessing a predictive model of a hand, refining positions of segments of the predictive model, matching the clusters of the points to the segments, and using the matched clusters to refine the positions of the matched segments. It also relates to distinguishing between alternative motions between two observed locations of a control object in a 3D sensory space by accessing first and second positions of a segment of a predictive model of a control object such that motion between the first position and the second position was at least partially occluded from observation in a 3D sensory space.

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.
