    Abstract: Aspects of the disclosure are directed to methods and apparatuses involving 3D imaging. In accordance with certain aspects, a plurality of images of a 3D object are captured while movement of the 3D object is sensed by a sensor physically coupled thereto. The plurality of images include complementary portions and a feature of the 3D object. Pose data is generated for one of the plurality of images, based on data corresponding to the sensed movement and on the feature. The complementary portions are combined to generate a visual 3D image of the 3D object, based on the pose data.

    Abstract: Methods, systems, apparatus, and computer-readable media (transitory or non-transitory) are described herein for scaling and rendering a virtual hand. According to an example, vision data may be received from a three-dimensional (“3D”) vision sensor. The vision data may capture at least a portion of a user in an environment, and may include data representing the user's hand relative to a touch interaction surface. The vision data may be processed to generate a 3D representation of the user's hand. A scaling center may be identified on the touch interaction surface to scale the 3D representation of the user's hand. The 3D representation of the user's hand may be scaled with respect to the identified scaling center using a scaling factor. The scaling factor may be based on a rendering constraint. A virtual hand may be rendered, e.g., on a display, based on the scaled 3D representation of the user's hand.

    Abstract: A display system includes a head-mountable 3D display device including at least one sensor to sense an absolute position and orientation of the 3D display device. The display system includes an accessory wearable by a user. The accessory includes at least one sensor to sense a relative position and orientation of the 3D display device relative to the accessory. An absolute position and orientation of a torso of the user may be determined based on the sensed absolute position and orientation of the 3D display device and the sensed relative position and orientation of the 3D display device relative to the accessory.

    Abstract: A stylus includes a housing, a tip portion at an end of the housing, and a control module within the housing, with the housing including a shape-changeable portion, and the control module to generate a first signal in response to the shape-changeable portion of the housing having a first effective cross-sectional area and generate a second signal in response to the shape-changeable portion of the housing having a second, different effective cross-sectional area.
