Abstract

An electronic device acquires a first expression image of a user in response to a first trigger operation and obtains a target image. Then, the electronic device sends an image generation request to a server. The image generation request includes the target image and initial expression information of the first expression image. The server generates a dynamic-effect file corresponding to the target image in response to the image generation request. The dynamic-effect file includes a dynamic-effect image obtained by rendering the target image based on the initial expression information. The server sends the dynamic-effect file to the wearable device. The wearable device displays a corresponding watch-face interface based on an acquired second expression image after detecting a second trigger operation. The watch-face interface includes the dynamic-effect image that matches an expression type of the second expression image.

First claim

What is claimed is:

1 . A display method for a watch-face interface, applied to an interaction system, wherein the interaction system comprises a wearable device, an electronic device, and a server, the wearable device is configured to display a watch-face interface, and the method comprises:
acquiring, by the electronic device, a first expression image of a user in response to a first trigger operation; obtaining, by the electronic device, a target image; sending, by the electronic device, an image generation request to the server, wherein the image generation request comprises the target image and initial expression information of the first expression image, and the initial expression information represents an expression type of the first expression image; generating, by the server, a dynamic-effect file corresponding to the target image in response to the image generation request, wherein the dynamic-effect file comprises a dynamic-effect image obtained by rendering the target image based on the initial expression information, and dynamic effect of the dynamic-effect image matches the expression type of the first expression image; sending, by the server, the dynamic-effect file to the wearable device; and displaying, by the wearable device, a corresponding watch-face interface based on an acquired second expression image after detecting a second trigger operation, wherein the watch-face interface comprises the dynamic-effect image that matches an expression type of the second expression image.

2 . The method according to claim 1 , wherein the displaying, by the wearable device, a corresponding watch-face interface based on an acquired second expression image after detecting a second trigger operation comprises:
acquiring, by the wearable device, the second expression image of the user after detecting the second trigger operation; recognizing, by the wearable device, the expression type of the second expression image; and displaying, by the wearable device, the corresponding watch-face interface based on target expression information, wherein the target expression information represents the expression type of the second expression image.

3 . The method according to claim 2 , wherein the displaying, by the wearable device, a corresponding watch-face interface based on an acquired second expression image comprises:
comparing the target expression information of the second expression image with effect information of the dynamic-effect image, wherein the effect information represents an expression type in the dynamic-effect image; and displaying a watch-face interface comprising the dynamic-effect image if the target expression information of the second expression image matches the effect information of the dynamic-effect image.

4 . The method according to claim 3 , wherein the target expression information and the effect information comprise feature point information, and the comparing, by the wearable device, the target expression information of the second expression image with effect information of the dynamic-effect image comprises:
comparing, by the wearable device, the feature point information of the target expression information with the feature point information of the effect information, wherein the feature point information represents an expression feature corresponding to an expression type; and the displaying a watch-face interface comprising the dynamic-effect image if the target expression information of the second expression image matches the effect information of the dynamic-effect image comprises: if the feature point information of the target expression information matches the feature point information of the effect information, determining that the target expression information of the second expression image matches the effect information of the dynamic-effect image, and displaying the watch-face interface comprising the dynamic-effect image.

5 . The method according to claim 3 , wherein the target expression information and the effect information comprise expression type identifiers, and the comparing, by the wearable device, the target expression information of the second expression image with effect information of the dynamic-effect image comprises:
comparing, by the wearable device, the expression type identifier of the target expression information with the expression type identifier of the effect information; and the displaying a watch-face interface comprising the dynamic-effect image if the target expression information of the second expression image matches the effect information of the dynamic-effect image comprises: if the expression type identifier of the target expression information matches the expression type identifier of the effect information, determining that the target expression information of the second expression image matches the effect information of the dynamic-effect image, and displaying the watch-face interface comprising the dynamic-effect image.

6 . The method according to claim 4 , wherein the method further comprises:
displaying a watch-face interface comprising the target image if the target expression information of the second expression image does not match the effect information of the dynamic-effect image.

7 . The method according to claim 1 , wherein the second trigger operation comprises a screen-on operation, and the screen-on operation comprises: the user lifts a wrist wearing the wearable device to the front of the user's face, or the user lifts a wrist wearing the wearable device and the user lowers the head.

8 . An interaction system, wherein the interaction system comprises an electronic device, a wearable device, and a server, wherein the wearable device is configured to display a watch-face interface, and the interaction system is configured to perform the display method comprises:
acquiring, by the electronic device, a first expression image of a user in response to a first trigger operation; obtaining, by the electronic device, a target image; sending, by the electronic device, an image generation request to the server, wherein the image generation request comprises the target image and initial expression information of the first expression image, and the initial expression information represents an expression type of the first expression image; generating, by the server, a dynamic-effect file corresponding to the target image in response to the image generation request, wherein the dynamic-effect file comprises a dynamic-effect image obtained by rendering the target image based on the initial expression information, and dynamic effect of the dynamic-effect image matches the expression type of the first expression image; sending, by the server, the dynamic-effect file to the wearable device; and displaying, by the wearable device, a corresponding watch-face interface based on an acquired second expression image after detecting a second trigger operation, wherein the watch-face interface comprises the dynamic-effect image that matches an expression type of the second expression image.

9 . The interaction system according to claim 8 , wherein the displaying, by the wearable device, a corresponding watch-face interface based on an acquired second expression image after detecting a second trigger operation comprises:
acquiring, by the wearable device, the second expression image of the user after detecting the second trigger operation; recognizing, by the wearable device, the expression type of the second expression image; and displaying, by the wearable device, the corresponding watch-face interface based on target expression information, wherein the target expression information represents the expression type of the second expres
