  • Publication number: 20240310921
    Abstract: Systems and methods for motion tracking on a hardware device without a camera and/or without a sufficiently powerful hardware processor, by offloading pose processing fully or partially to a mobile device, are disclosed. Methods executable on the hardware device include receiving pose data associated with a user from the mobile device, and performing a touchless control of an application on the hardware device, based on the received pose data. Methods executable on the mobile device include capturing at least one image associated with a user, performing a pose recognition algorithm on the mobile device, based on the captured image, to generate pose data for performing a touchless control of an application on the hardware device, and transmitting the pose data to the hardware device, using the network connection. The methods and systems include embodiments where the pose recognition algorithm uses machine learning.

  • Patent number: 8330639
    Abstract: A remote controller for toys includes a user interface which applies the low-cost capacitive sensing method with the remote controller. Users can touch and/or drag on a remote controller surface by fingers to remotely control the movement of R/C cars, planes, helicopters or a boat. The remote controller is essentially a flat faced unit and there is no need for protruding control sticks or pushbuttons. This controller is applicable to different types of remote control toys with digital proportional control on speed and steering control. The remote controller is a symmetric product design whereby the controller is easily operable with left and right hand conventions.

  • Publication number: 20120114036
    Abstract: The present invention relates to method and apparatus for multiview video coding. In particular, the present invention describes a disparity compensated prediction to exploit the inter-view correlation in multiview video coding by providing stretching, compression, and shearing (SCSH) disparity compensation to approximate the actual disparity effects in addition to the translational disparity. A sub-sampled block-matching disparity estimation technique is provided to implement the SCSH disparity compensation which makes use of the interpolated reference frames for subpixel motion and disparity estimation in conventional hybrid video coding structure.

  • Patent number: 8170110
    Abstract: In accordance with an example embodiment of the present invention, the present invention provides method and apparatus for motion compensated prediction. Apart from translational motion, zoom motion is taken into account by sampling an interpolated frame with one or more selected sampling rates to generate one or more zoom reference frames; matching a frame with the zoom reference frames; and determining one or more motion data.

  • Patent number: 8055025
    Abstract: A motion estimation method uses a search start point and a plurality of search paths extending from the start point. The method finds an image point along the plurality of search paths that has a minimum comparison value with a reference image block. This image point with a minimum comparison value becomes the new search start point, with a plurality of new search paths extending from the new start point. The method then finds the image point along the plurality of new search paths that has a minimum comparison value with the reference image block. The cycle repeats until points on the search paths have comparison values higher than the start point.
