  • Face detection guided sound source localization pan angle post processing for smart camera talker tracking and framing
    Patent number: 11937057
    Abstract: A videoconferencing system includes a camera acquiring image data and a microphone array acquiring audio data. Image data is used in conjunction with sound source localization (SSL) data to locate a talker depicted in the image data. SSL processes the audio data and determines SSL pan angle values indicative of an estimated direction of a sound. Columns of pixels in an image are associated with bins. A bin count is incremented for each SSL pan angle value of the audio data that falls within a given bin. A bounding box in the image data is determined that encompasses a face depicted in the image data. A range of pixels is determined for the bounding box, such as extending from a leftmost column to a rightmost column. The bin with the highest bin count that also overlaps a range of pixels for a bounding box is deemed to contain the talker.

  • Haptic device activation for virtual events that exceed view boundary
    Patent number: 11934579
    Abstract: An example system includes a strap, a display, a plurality of haptic devices, and a notification engine to cause activation of a haptic device in response to a virtual event that exceeds the view boundary. In an example, instructions may cause a processor to map a relative location of a virtual event to a corresponding location on a strap of an electronic device and cause activation of a haptic device at the corresponding location on the strap in response to a determination that the relative location of the virtual event exceeds a view boundary. In an example method for providing a virtual reality session, a virtual event is determined to correspond to an informational notification, a haptic device is identified to correspond to a location of the virtual event, and activation of the haptic device in an informational notification mode is synchronized with the virtual event.
