Method and device for multiple-terminal collaboratively updating displayed content

Abstract

The present disclosure discloses a method and device for multiple-terminal collaboratively updating a displayed content. The method includes: displaying, by the first terminal, the first application interface of the first collaborative whiteboard application, where the first collaborative whiteboard application and the second collaborative whiteboard application of the second terminal are in a collaborative mode, where the second terminal displays the second application interface of the second collaborative whiteboard application; receiving a controlling parameter transmitted by the second terminal, where the controlling parameter is generated by the second terminal when receiving a controlling operation performed on the second application interface; and updating, by the first terminal, a content of the first application interface based on the controlling parameter, where the controlling operation is determined as a moving operation, the first canvas is moved based on the controlling parameter, and when an edge of the first canvas coincides with an edge of the first application interface in the same direction, re-rendering, by the first terminal, the content in the first canvas. The present disclosure solves the technical problem that the following terminal is difficult to follow when the canvas of the followed terminal expands infinitely in the prior art.
