    Abstract: An electronic device may be provided with control circuitry for locating lost items. The control circuitry may determine where an item is located and may use the display or other output device to guide a user to the item. The display may display a visual guide such as an arrow, a sphere, a circle, a compass, or other visual aid that points the user in the direction of the item. The control circuitry may change the size or other characteristic of the visual aid on the display as the distance between the electronic device and the object changes. The control circuitry may change the location of the visual aid on the display as the orientation of the electronic device relative to the object changes. The display may overlay the visual aid onto live images of the user's surroundings as they are captured by a camera.

    Abstract: An electronic device may use information about the location of nearby devices to make sharing with those devices more intuitive for a user. The electronic device may include control circuitry, wireless circuitry including first and second antennas, and motion sensor circuitry. The control circuitry may determine the location of a nearby electronic device by calculating the angle of arrival of signals that are transmitted by the nearby electronic device. To obtain a complete, unambiguous angle of arrival solution, the electronic device may be moved into different positions during angle of arrival measurement operations. At each position, the control circuitry may calculate a phase difference associated with the received signals. Motion sensor circuitry may gather motion data as the electronic device is moved into the different positions. The control circuitry may use the received antenna signals and the motion data to determine the complete angle of arrival solution.
