  • Patent number: 11864864
    Abstract: A wearable device and a method for performing a registration process in the wearable device are provided. The wearable device includes a light source, a light sensor and a microcontroller that performs the method. In the method, the light source is activated to emit a detection light and the light sensor senses a reflected light. A light intensity of the reflected light is calculated. A registration value is produced based on the light intensity. Specifically, the detection light with a specific frequency to be registered in the registration value is used as a reference to detect whether the wearable device is properly worn by a person. For example, since the wearable device can be worn on the person's wrist, the registration value is used to detect whether the wearable device is away from the wrist.

  • Patent number: 11862126
    Abstract: An example non-transitory machine-readable storage medium includes instructions to, when executed by the processor, identify an object depicted in a video scene, wherein the video scene is displayed in a graphical user interface (GUI). The example instructions are executable to 1) identify coordinates of the object depicted in the video scene, wherein the coordinates are relative to the GUI and 2) identify coordinates of an inset window which is smaller than the GUI and overlaps the video scene. The example instructions are executable to compare the coordinates of the object with the coordinates of the inset window to determine an overlap of the inset window with the object. Responsive to an identified overlap of the inset window and the object, the instructions are executable to alter a display characteristic of the inset window to avoid the overlap of the inset window with the object.
