Abstract: A gesture control method applied to a virtual reality (VR) device, where gesture location information of a user of the VR device is obtained, a depth distance from a depth sensor to a hand of the user is detected using the depth sensor, and a hand movement area of the user is divided into a selection area and a command area based on a result of comparing the depth distance with a preset depth threshold. When the detected depth distance is not greater than the preset depth threshold, the user may select a to-be-operated object on a current display page, and when the detected depth distance is greater than the preset depth threshold, the user may perform a command operation on the to-be-operated object.

Abstract: 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.
