Abstract

This application provides a screen projection method and an electronic device. The method includes: detecting a position of one or more other electronic devices relative to a first electronic device by using a Bluetooth angle of arrival (AOA) technology (S 1601 ); determining a target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the first electronic device (S 1602 ); detecting a screen projection operation (S 1603 ), and sending first information to the target device in response to the screen projection operation, so that the target device displays or plays the first information (S 1604 ). In the method, the electronic device may automatically determine a target electronic device from a plurality of electronic devices, and then project a screen on the target electronic device, to facilitate operations and improve user experience.

First claim

What is claimed is:

1. An electronic device, comprising at least one processor and a memory, wherein the memory is configured to store one or more computer programs, wherein when the one or more computer programs stored in the memory are executed by the at least one processor, the electronic device is configured to:
detect a position of one or more other electronic devices relative to the electronic device by using a Bluetooth angle of arrival (AOA) technology;
determine a target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the electronic device;
detect a screen projection operation; and
send, in response to the screen projection operation, first information to the target device, so that the target device displays or plays the first information;
obtain a capability of the target device; and determine, based on the capability of the target device, first information that matches the capability
wherein when obtaining the capability of the target device, the electronic device is specifically configured to:
send query information to the target device, wherein the query information is used to query whether the target device has the screen display function and/or whether the target device has the audio playback function; and
receive feedback information sent by the target device, and determine the capability of the target device based on the feedback information; and
wherein that the query information is used to query whether the target device has the screen display function comprises: the query information is used to query whether the target device has a display and whether the display is lit up; and
that the query information is used to query whether the target device has the audio playback function comprises:
the query information is used to query whether the target device bas an audio playback module and whether the audio playback module is enabled.

2. The electronic device according to claim 1 , wherein the electronic device is specifically configured to:
if the target device has no screen display function but has an audio playback function, determine that audio information currently played by the electronic device is the first information; or
if the target device has a screen display function but has no audio playback function, determine that display information currently displayed by the electronic device is the first information; or
if the target device has a screen display function and an audio playback function, determine that audio information currently played by the electronic device and display information currently displayed by the electronic device is the first information.

3. The electronic device according to claim 1 , wherein the screen projection operation comprises:
an operation that three fingers slide simultaneously on a display; or
an operation that at least two fingers touch and hold a display simultaneously and slide upward without an interval after the touching and holding; or
an operation that at least one knuckle double taps a display simultaneously; or
an operation that at least one knuckle touches and holds a display simultaneously and slides upward without an interval after the touching and holding; or
an operation that a palm is in contact with a display and slides upward on the display; or
an operation that a palm slides above a display when the palm is suspended over the display and is not in contact with the display.

4. The electronic device according to claim 1 , wherein the electronic device further comprises a display;
the display is configured to display a first interface after the at least one processor detects the position of the one or more other electronic devices relative to the electronic device by using the Bluetooth angle of arrival (AOA) technology, wherein
the first interface comprises a first device identifier of the electronic device and another device identifier of each of the one or more other electronic devices, the other device identifiers are distributed around the first device identifier based on the position relative to the electronic device, the first device identifier comprises a first direction arrow, and a pointing direction of the first direction arrow changes with movement of the electronic device; and
the display is further configured to: after the at least one processor determines the target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the electronic device, display the first direction arrow in the first interface, so that the first direction arrow points to a device identifier of the target device.

5. The electronic device according to claim 1 , wherein before sending, in response to the screen projection operation, the first information to the target device, the electronic device is further configured to output prompt information by using the display of the electronic device, wherein the prompt information is used to prompt a user whether to connect to the target device, and the electronic device is further configured to: after the electronic device receives an instruction of determining to connect to the target device, establish a connection to the target device; or
when sending, in response to the screen projection operation, the first information to the target device, the electronic device is specifically configured to:
in response to the screen projection operation, establish a connection to the target device, and send the first information to the target device.

6. The electronic device according to claim 1 , wherein when determining the target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the electronic device, the electronic device is specifically configured to:
determine a target device that is in the one or more other electronic devices and that is in a preset position range; or
determine a target device that is in the one or more other electronic devices and that is directly in front of the electronic device.

7. An electronic device, comprising at least one processor and a memory, wherein the memory is configured to store one or more computer programs, wherein when the one or more computer programs stored in the memory are executed by the at least one processor, the electronic device is configured to:
detect a position of one or more other electronic devices relative to the electronic device by using a Bluetooth angle of arrival (AOA) technology:
determine a target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the electronic device:
detect a screen projection operation; and
send, in response to the screen projection operation, first information to the target device so that the target device displays or plays the first information;
obtain a capability of the target device; and determine, based on the capability of the target device, first information that matches the capability
wherein the electronic device further comprises a display;
the display is configured to display a first interface after the at least one processor detects the position of the one or more other electronic devices relative to the electronic device by using the Bluetooth angle of arrival (AOA) technology, wherein
the first interface comprises a first device identifier of the electronic device and another device identifier of each of the one or more other electronic devices, the other device identifiers are distributed around the first device identifier based on the position relative to the electronic device, the first device identifier comprises a first direction a
