Abstract

A scene switching method includes: determining whether a user moves from a first scene to a second scene or not; if yes, acquiring voiceprint information of the user in the second scene; determining each device to be switched in the first scene according to the voiceprint information, and obtaining an operation state of the device to be switched; and determining an operation state of each target device in the second scene.

First claim

What is claimed is:

1 . A scene switching method, comprising:
determining, by a processor of a terminal, whether a user moves from a first scene to a second scene; in response to determining that the user moves from the first scene to the second scene, acquiring, by the processor of the terminal, voiceprint information of the user in the second scene; determining, by the processor of the terminal, based on the voiceprint information in the second scene, one or more devices to be switched in the first scene, and obtaining, by the processor of the terminal, respective first operation state information of the one or more devices to be switched; and determining, by the processor of the terminal, respective second operation state information of one or more target devices in the second scene based on the respective first operation state information, wherein the one or more target devices match the one or more devices to be switched, respectively; wherein the determining of the one or more devices to be switched comprises: obtaining, by the processor of the terminal, respective first device information of one or more first devices that are turned on in the first scene and respective second device information of the one or more target devices in the second scene; and in response to determining that voiceprint information in the first scene matches the voiceprint information in the second scene, comparing, by the processor of the terminal, the respective first device information with the respective second device information to determine, as the one or more devices to be switched, one or more of the one or more first devices respectively matching the one or more target devices in terms of device information; wherein the determining of the respective second operation state information based on the respective first operation state information comprises: sending, by the processor of the terminal, the respective first operation state information to the one or more target devices, respectively, to configure, based on the respective first operation state information, one or more operation parameters respectively for the one or more target devices to obtain the respective second operation state information; after sending the respective first operation state information to the one or more target devices, respectively, to configure the one or more operation parameters respectively for the one or more target devices, receiving, by the processor of the terminal, result information fed back by the one or more target devices in the second scene, to determine whether the one or more operation parameters respectively for the one or more target devices have been successfully configured based on the respective first operation state information; in response to determining that the one or more operation parameters respectively for the one or more target devices have been successfully configured, sending, by the processor of the terminal, a control instruction to turn off the one or more devices to be switched in the first scene.

2 . The scene switching method of claim 1 , wherein the determining of whether the user moves from the first scene to the second scene comprises:
obtaining respective first position information of one or more first devices that are turned on in the first scene and respective second position information of the one or more target devices in the second scene; and determining whether the respective first position information is at least partially different from the respective second position information, to determine whether the user moves from the first scene to the second scene.

3 . The scene switching method of claim 1 , wherein the acquiring of the voiceprint information of the user in the second scene comprises:
upon receiving one or more scene switching instructions, acquiring the voiceprint information of the user in the second scene.

4 . The scene switching method of claim 1 , further comprising: before determining whether the user moves from the first scene to the second scene,
obtaining a device turning-on instruction in the first scene, and obtaining voiceprint information in the first scene based on the device turning-on instruction; and associating the voiceprint information in the first scene with the first scene.

5 . The scene switching method of claim 3 , wherein
the one or more scene switching instructions comprise a plurality of scene switching instructions; the acquiring of the voiceprint information of the user in the second scene upon receiving the one or more scene switching instructions comprises: upon receiving the plurality of scene switching instructions, obtaining respective first voiceprint information corresponding to the plurality of scene switching instructions; comparing the respective first voiceprint information with target voiceprint information, to determine a piece of voiceprint information of the respective first voiceprint information matching the target voiceprint information as second voiceprint information; determining one of the plurality of scene switching instructions corresponding to the second voiceprint information as a target scene switching instruction, and determining a user corresponding to the target scene switching instruction as a target user; and acquiring voiceprint information of the target user as the voiceprint information of the user in the second scene.

6 . The scene switching method of claim 1 , further comprising: after comparing the respective first device information with the respective second device information to determine, as the one or more devices to be switched, the one or more of the one or more first devices,
in response to determining that the one or more devices to be switched comprise a first video play device, obtaining play content and play progress of the video play device; and sending the play content and the play progress to a second video play device in the second scene, to enable the second video play device to display the play content according to the play progress.

7 . A terminal comprising:
a processor; and a memory storing thereon a program executable by the processor to perform operations comprising: determining, by the processor of the terminal, whether a user moves from a first scene to a second scene; in response to determining that the user moves from the first scene to the second scene, acquiring voiceprint information of the user in the second scene; determining, by the processor of the terminal, based on the voiceprint information in the second scene, one or more devices to be switched in the first scene, and obtaining, by the processor of the terminal, respective first operation state information of the one or more devices to be switched; and determining, by the processor of the terminal, respective second operation state information of one or more target devices in the second scene based on the respective first operation state information, wherein the one or more target devices match the one or more devices to be switched, respectively; wherein the determining of the one or more devices to be switched comprises: obtaining, by the processor of the terminal, respective first device information of one or more first devices that are turned on in the first scene and respective second device information of the one or more target devices in the second scene; and in response to determining that voiceprint information in the first scene matches the voiceprint information in the second scene, comparing, by the processor of the terminal, the respective first device information with the respective second device information to determine, as the one or more devices to be switched, one or more of the one or more first devices respectively matching t
