Abstract

A method, a device, and a system for interactive video display, relate to the field of multimedia technologies, and can resolve a problem in the prior art that browsing experience of a user is not real because a visible region is simply changed only according to a panning change of a location of the user. A specific solution is acquiring posture information of a user, where the posture information includes viewing angle information of the user and location information of the user, and adjusting, according to the posture information, an unadjusted visible region, in a video, for being displayed on a client in order to obtain an adjusted visible region currently for being displayed on the client. The embodiments of the present invention are used for performing interactive video display.

First claim

What is claimed is:

1 . An interactive video display method, comprising:
acquiring posture information of a user, wherein the posture information comprises viewing angle information of the user and location information of the user; and adjusting, according to the posture information, an unadjusted visible region, in a video, for being displayed on a client in order to obtain an adjusted visible region currently for being displayed on the client.

2 . The method according to claim 1 , wherein the location information of the user comprises a vertical distance between the user and a plane of the client, and wherein adjusting, according to the posture information, the unadjusted visible region, in the video, for being displayed on the client in order to obtain the adjusted visible region currently for being displayed on the client comprises:
acquiring at least one of a region size change value and region displacement of the unadjusted visible region according to the viewing angle information of the user and the vertical distance, wherein the region size change value comprises a width change value of the unadjusted visible region and a height change value of the unadjusted visible region, and wherein the region displacement comprises horizontal displacement of the unadjusted visible region and vertical displacement of the unadjusted visible region; and adjusting the unadjusted visible region according to the at least one of the region size change value and the region displacement in order to obtain the adjusted visible region.

3 . The method according to claim 2 , wherein adjusting the unadjusted visible region according to the at least one of the region size change value and the region displacement in order to obtain the adjusted visible region comprises:
adjusting an unadjusted region of a virtual window picture according to the region size change value and the region displacement in order to obtain an adjusted region of the virtual window picture when the vertical distance is greater than or equal to a preset distance threshold; fully covering an unadjusted region of a dynamic image with an adjusted picture that is presented in the adjusted region of the virtual window picture to obtain the adjusted visible region when the vertical distance is greater than or equal to the preset distance threshold, wherein the video is the dynamic image on which the virtual window picture is superimposed, wherein the virtual window picture comprises a transparent region, a range that is in the dynamic image and that is covered by the transparent region of the virtual window picture is visible, and wherein the unadjusted visible region is obtained by superimposing the unadjusted region of the virtual window picture on the unadjusted region of the dynamic image; and adjusting the unadjusted visible region according to the region displacement in order to obtain the adjusted visible region when the vertical distance is less than the preset distance threshold.

4 . The method according to claim 1 , wherein viewing angle information of the user comprises face orientation information of the user, and wherein the face orientation information of the user comprises an angle by which the face orientation of the user rotates around a coronal axis and the angle by which the face orientation of the user rotates around a vertical axis.

5 . The method according to claim 4 , wherein a region size change value of the unadjusted visible region is acquired using the following formulas:
