Abstract: A location tracking system is provided for tracking the location of a child or other individual. The location tracking system includes a location server and one or more location tracking devices. Communication protocols are provided for communications between the location server and the location tracking devices. The communication protocols provide a low complexity and low cost solution for location tracking applications.

Abstract: Various examples are directed to the generating and playback of panoramic videos comprising a plurality of tiles. Each tile may be a video having a tile field-of-view that is a portion of a full field-of-view of the panoramic video. An active field-of-view may be displayed from the first tile, where the active field-of-view is selected from a first tile field-of-view. A translate command may indicate a translate direction for the active field of view. A second tile may be requested. The second tile may have a second tile field-of-view that is adjacent to the first file field-of-view in the translate direction. The active field of view may be translated in the translate direction. When the active field-of-view reaches an edge of the first tile field-of-view, the active field-of-view may be displayed, at least in part, from the second tile.

Abstract: Various examples are directed to displaying a panoramic video at an interface comprising a focus region and a thumbnail region. The focus region may display an active field-of-view of the panoramic video, where the active field-of-view is a portion selected from the full field-of-view of the panoramic video. The thumbnail region may display a thumbnail version of the panoramic video comprising a thumbnail field-of-view that is equivalent to the full field-of-view. A distribution of color saturation levels of the thumbnail version may indicates a distribution of fields-of-view selectable from the full field-of-view.
