1. An electronic device, comprising:
ultra-wideband receiver circuitry configured to receive ultra-wideband radio-frequency signals from an object;
control circuitry configured to:
determine a non-zero angle of arrival of the ultra-wideband radio-frequency signals; and
determine an orientation of the electronic device relative to the object based on the non-zero angle of arrival of the ultra-wideband radio-frequency signals; and
determine a distance to the object based on the ultra-wideband radio-frequency signals; and
a display configured to display a visual guide on a non-camera view background that guides a user to the object, wherein the display:
changes a characteristic of the visual guide on the non-camera view background in response to a change in the distance to the object;
changes a location of the visual guide on the non-camera view background in response to a change in the orientation of the electronic device relative to the object; and
changes the non-camera view background to a live camera view background when the distance is less than a threshold distance, wherein the visual guide is displayed on the live camera view background.
