摘要： A single image sensor including an array of uniformly and continuously spaced light-sensing pixels in conjunction with a plurality of lenses that focus light reflected from an object onto a plurality of different pixel regions of the image sensor, each lens focusing light on a different one of the pixel regions enables a controller, including a processor and an object detection module, coupled to the single image to analyze the pixel regions, to generate a three-dimensional (3D) image of the object through a plurality of images obtained with the image sensor, generate a depth map that calculates depth values for pixels of at least the object, detect 3D motion of the object using the depth values, create a 3D model of the object based on the 3D image, and track 3D motion of the object based on the 3D model.

摘要： 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.

摘要： The technology disclosed relates to determining positional information of an object in a field of view. In particular, it relates to calculating a distance of the object from a reference such as a sensor including scanning the field of view by selectively illuminating directionally oriented light sources and measuring one or more differences in property of returning light emitted from the light sources and reflected from the object. The property can be intensity or phase difference of the light. It also relates to finding an object in a region of space. In particular, it relates to scanning the region of space with directionally controllable illumination, determining a difference in a property of the illumination received for two or more points in the scanning, and determining positional information of the object based in part upon the points in the scanning corresponding to the difference in the property.

摘要： 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.

摘要： A method and system determines object orientation using a light source to create a shadow line extending from the light source. A camera captures an image including the shadow line on an object surface. An orientation module determines the surface orientation from the shadow line. In some examples a transparency imperfection in a window through which a camera receives light can be detected and a message sent to a user as to the presence of a light-blocking or light-distorting substance or particle. A system can control illumination while imaging an object in space using a light source mounted to a support structure so a camera captures an image of the illuminated object. Direct illumination of the camera by light from the light source can be prevented such as by blocking the light or using a light-transmissive window adjacent the camera to reject light transmitted directly from the light source.

摘要： Embodiments of display control based on dynamic user interactions generally include capturing a plurality of temporally sequential images of the user, or a body part or other control object manipulated by the user, and computationally analyzing the images to recognize a gesture performed by the user. In some embodiments, a scale indicative of an actual gesture distance traversed in performance of the gesture is identified, and a movement or action is displayed on the device based, at least in part, on a ratio between the identified scale and the scale of the displayed movement. In some embodiments, a degree of completion of the recognized gesture is determined, and the display contents are modified in accordance therewith. In some embodiments, a dominant gesture is computationally determined from among a plurality of user gestures, and an action displayed on the device is based on the dominant gesture.

摘要： The technology disclosed can provide for improved motion capture and touchless interface operations by enabling tunable control of operational parameters without compromising the quality of image based recognition, tracking of conformation and/or motion, and/or characterization of objects (including objects having one or more articulating members (i.e., humans and/or animals and/or machines). Examples of tunable operational parameters include frame rate, field of view, contrast detection, light source intensity, pulse rate, and/or clock rate. Among other aspects, operational parameters can be changed based upon detecting presence and/or motion of an object indicating input (e.g., control information, input data, etc.) to the touchless interface, either alone or in conjunction with presence (or absence or degree) of one or more condition(s) such as accuracy conditions, resource conditions, application conditions, others, and/or combinations thereof.

摘要： The technology disclosed relates to identifying an object in a field of view of a camera. In particular, it relates to identifying a display in the field of view of the camera. This is achieved by monitoring a space including acquiring a series of image frames of the space using the camera and detecting one or more light sources in the series of image frames. Further, one or more frequencies of periodic intensity or brightness variations, also referred to as ‘refresh rate’, of light emitted from the light sources is measured. Based on the one or more frequencies of periodic intensity variations of light emitted from the light sources, at least one display that includes the light sources is identified.
