Method for determining orientation information and electronic device

A method for determining orientation information, the method comprising:

• sending, by a second electronic device, a first sequence to a first electronic device;
• and
• sending, by the second electronic device, a second sequence to the first electronic device, wherein the first sequence is associated with the second sequence, the second sequence is used by the first electronic device to determine an electronic device sending the first sequence, and the first sequence is used by the first electronic device to determine orientation information of the second electronic device;
• wherein the sending the first sequence to the first electronic device comprises:
• sending a plurality of first sequences to the first electronic device by using a plurality of speakers, respectively, wherein the plurality of speakers are in one-to-one correspondence with the plurality of first sequences;
• and
• wherein the sending the second sequence to the first electronic device comprises:
• sending a plurality of second sequences to the first electronic device by using the plurality of speakers, respectively, wherein the plurality of speakers are in one-to-one correspondence with the plurality of second sequences, wherein a given first sequence and a given second sequence that are sent by using a same speaker of the plurality of speakers are associated.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and when the computer instructions are run on an electronic device, the electronic device is configured to implement operations comprising:

• receiving N sequences, wherein N is a positive integer greater than 1;
• determining a sequence with a best signal quality among the N sequences as a first sequence;
• receiving a second sequence, wherein the first sequence is associated with the second sequence;
• determining, based on the second sequence, whether a device sending the first sequence is a second electronic device;
• and
• based on determining that the device sending the first sequence is the second electronic device, determining orientation information of the second electronic device based on the first sequence.
