Abstract
This application provides a method for directing a user and an electronic device. A first electronic device exchanges an ultrasonic signal with a second electronic device, and the first electronic device outputs a directing signal according to the ultrasonic signal and angle information between the two devices, to guide user to search for the second electronic device. The first electronic device and the second electronic device do not need to be installed with a UWB chip, thereby reducing costs.
Claims15
A method for a first electronic device directing a user, the method comprising:
- determining, by the first electronic device and based on a first ultrasonic signal sent by a second electronic device, information about a first angle of the second electronic device relative to the first electronic device;
- outputting, by the first electronic device, a first prompt signal, the first prompt signal prompting the user to rotate the first electronic device;
- determining, by the first electronic device and based on a second ultrasonic signal sent by the second electronic device, information about a second angle of the second electronic device relative to the first electronic device;
- and
- outputting, by the first electronic device, a first directing signal based on the information about the first angle, the information about the second angle, and a rotation angle of the first electronic device, the first directing signal directing the user to search for the second electronic device.
A first electronic device, comprising:
- a memory storing instructions;
- and
- at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
- determining, based on a first ultrasonic signal sent by a second electronic device, information about a first angle of the second electronic device relative to the first electronic device;
- outputting a first prompt signal, the first prompt signal prompting the user to rotate the first electronic device;
- determining, based on a second ultrasonic signal sent by the second electronic device, information about a second angle of the second electronic device relative to the first electronic device;
- and
- outputting a first directing signal based on the information about the first angle, the information about the second angle, and a rotation angle of the first electronic device, the first directing signal directing the user to search for the second electronic device.
A non-transitory computer-readable media storing computer instructions that configure at least one processor of a first electronic device, upon execution of the instructions, to perform the following steps:
- determining, based on a first ultrasonic signal sent by a second electronic device, information about a first angle of the second electronic device relative to the first electronic device;
- outputting a first prompt signal, the first prompt signal prompting the user to rotate the first electronic device;
- determining, based on a second ultrasonic signal sent by the second electronic device, information about a second angle of the second electronic device relative to the first electronic device;
- and
- outputting a first directing signal based on the information about the first angle, the information about the second angle, and a rotation angle of the first electronic device, the first directing signal directing the user to search for the second electronic device.
