For example, the control circuitry may gather activity information for the user, such as heart rate, calories burned, and step count, and analyze a distance component and a speed component for periods in which the user has walked. Individual 6 minute walk distance estimates may be generated based on each of the activity information, distance component, and speed component.

In one implementation, a method for dynamically determining presentation and transitional regions for content delivery. The method includes obtaining a first set of characteristics associated with a physical environment; and detecting a request to cause presentation of virtual content. In response to detecting the request, the method also includes obtaining a second set of characteristics associated with the virtual content; generating a presentation region for the virtual content based at least in part on the first and second sets of characteristics; and generating a transitional region provided to at least partially surround the presentation region based at least in part on the first and second sets of characteristics. The method further includes concurrently presenting the virtual content within the presentation region and the transitional region at least partially surrounding the presentation region.
An electronic device may include an antenna and a coaxial cable coupled to the antenna. The coaxial cable may have a signal conductor coupled to an antenna resonating element of the antenna and a ground conductor coupled to an antenna ground of the antenna. The ground conductor may include an ungrounded segment that is separated from the antenna ground by a gap. A capacitive coupling between the ground conductor in the ungrounded segment and the antenna ground via the gap may form an impedance matching component for the coaxial cable. A dielectric retention layer may overlap the coaxial cable and hold the coaxial cable in place relative to the antenna ground to maintain the gap.
This disclosure provides more effective and/or efficient techniques for detecting faults with physical components using an example of selectively causing output of light into a cover and capturing an image of the cover to determine whether the light is visible in the image. Some techniques are described herein for detecting misalignment of one or more physical components (e.g., a cover or a camera). Other techniques are described herein for detecting contaminants (e.g., substances at or near a surface of a physical component and/or a physical change to the physical component, such as a deformation or a crack of the cover) affecting data captured by a sensor.
