A text input method and apparatus based on a virtual keyboard are provided, which relate to the field of human-computer interaction, and resolve a problem of how to complete text input based on the virtual keyboard. The method includes an electronic device that detects key points of a first hand based on an image including the first hand after obtaining the image including the first hand, and projects a virtual keyboard on the first hand based on the key points of the first hand. Further, after obtaining an image including the first hand and a finger of a second hand, the electronic device identifies, based on the image including the first hand and the finger of the second hand, a contact state or a pressing state between the finger of the second hand and the first hand.

Text input method and apparatus based on virtual keyboard

A screen interaction method and apparatus for an electronic device are disclosed, to determine a target user from a plurality of users and control a picture displayed on a screen of the electronic device based on an action of the target user. The method includes: obtaining, by using a camera, an image including the plurality of users in front of a screen, recognizing respective actions of the plurality of users in the image based on the image including the plurality of users, comparing the actions of the plurality of users with a preset action, determining a user who performs an action matching the preset action as the target user, and controlling a picture displayed on the screen of the electronic device based on the action of the target user.

Screen interaction method and apparatus for electronic device

The present disclosure discloses a synchronization object determining method, apparatus, and system, where the method includes determining a first distance between the first terminal and the second terminal in a display picture according to location information of the first terminal and location information of the second terminal, and predicting a second distance between the first terminal and the second terminal after specified duration in the display picture, and classifying, by the synchronization device, the second terminal as a synchronization object of the first terminal if the first distance is greater than the second distance. According to the foregoing method, a proper synchronization object is selected for each terminal according to a mobility feature of a terminal. Therefore, on the one hand, an objective of synchronization can be achieved.
