An apparatus comprising a processor and a memory that cause the apparatus to perform receiving a video indicating a motion, generating a set of scalar representations of movement based, at least in part, on at least part of the video, and identifying at least one predetermined motion that correlates to the set of scalar representations of movement is disclosed.

Method and apparatus for determining motion

A platform that is configured to be removably placed symmetrically on or about a user's head has at least a first transducer configured to capture vibration of the user's skull or facial movement generated by the user's voice activity and to detect the user's speaking activity. This first transducer converts the vibration or facial movement into a first electrical audio signal. The electrical audio signal from the first transducer is processed by circuitry or embodied software as voiced frames and/or as unvoiced frames, in which the voiced frames and/or the unvoiced frames are defined based at least on the first electrical audio signal. Multiple embodiments follow from this: where the first transducer is a vibration sensor; where voice is captured by an air microphone and filtering adaptation differs for the voiced versus unvoiced frames as defined by the first transducer, and another with at least three air microphones.

Head-mounted sound capture device

An apparatus including an air-conduction transducer and a bone conduction transducer. The air-conduction transducer is configured to convert a first frequency band component of an electrical audio signal into acoustic energy to be delivered to an ear canal of a user. The bone conduction transducer is configured to convert a second, at least partially different, frequency band component of the electrical audio signal into mechanical energy to be delivered to a skull of the user. The apparatus is configured to deliver both forms of the energies to the user at a substantially same time to provide a combined audio delivery result to the user.

Apparatus and method for audio delivery with different sound conduction transducers

An apparatus, comprising a processor and memory configured to cause the apparatus to perform at least the following: receiving a video indicating a motion, generating a set of normalized representations of movement based, at least in part, on the video, evaluating a reference set of representations with respect to the set of normalized representations of the movement, and determining that at least one predetermined motion correlates to the set of normalized representations of the movement based, at least in part, on the evaluation is disclosed.

A gradient-based silhouette projection method for rendering the surface of a 3-D object is described herein. A set of imaging points is selected for imaging the object. The object is imaged from each of the selected imaging points to generate a set of images and a set of binary silhouettes are extracted from the images of the object, with at least one silhouette per image. The binary silhouettes are each filtered to generate an equal number of gradient silhouettes. Each of the gradient silhouettes is projected to generate a set of gradient volume projections that are combined to yield a single combined gradient volume. A 3-D isosurface is generated from the combined gradient volume, with the 3-D isosurface thereby representing the 3-D object. In one example described herein, the binary silhouettes are filtered to generate gradient silhouettes by determining tubular neighborhoods for the binary silhouettes. The gradient volume projections are represented by voxels. The 3-D isosurface is determined from the combined gradient volume by applying a marching cubes algorithm to the voxels representing the combined gradient volume. A set of polygons representing the 3-D isosurface is generated by approximately determining the set of polygons representing the locus of all lines that do not intersect the 3D isosurface. The set of polygons is subsequently textured based upon texture information provided in the set of input images or from other sources. The various steps may be repeated while the object moves or otherwise changes. A technique employing only a single initial silhouette is also described. Apparatus embodiments are also described.
