Abstract

The present disclosure provides an information display method, a display device, an electronic device, and a computer-readable medium, the information display method including: in a case where a first display device displays content to be annotated, displaying annotation information corresponding to the content to be annotated, in response to an annotation operation for the content to be annotated; and sending the annotation information to a second display device, so that the second display device displays the annotation information in an area corresponding to the content to be annotated.

First claim

What is claimed is:

1 . An information display method for a second display device, comprising:
displaying annotation information in an area corresponding to content to be annotated on the second display device, in response to the annotation information for the content to be annotated, which annotation information is sent by a first display device, wherein the content to be annotated is content of a partial area in full-area display content of the second display device, wherein before the displaying the annotation information in the area corresponding to the content to be annotated on the second display device, in response to the annotation information for the content to be annotated, which annotation information is sent by the first display device, the method further comprises: displaying the full-area display content; in a case where a selection cursor is triggered, acquiring a plurality of display positions of the selection cursor in a first time period; determining an area to be annotated according to the plurality of display positions of the selection cursor, and taking display content in the area to be annotated as the content to be annotated; and sending the content to be annotated to the first display device, so that the first display device displays the content to be annotated, wherein the selection cursor is a cursor displayed on the second display device and controlled by a controller, the controller is used for controlling the display position of the selection cursor on the second display device, the controller comprises a selection state, and the first time period is a time period between a start moment and an end moment of the selection state of the controller.

2 . The method according to claim 1 , wherein the determining the area to be annotated according to the plurality of display positions of the selection cursor, comprises:
acquiring position coordinates in a first coordinate system corresponding to the plurality of display positions of the selection cursor, wherein an X direction of the first coordinate system is a column direction of pixels of the second display device, and a Y direction of the first coordinate system is a row direction of pixels of the second display device; and determining the area to be annotated according to a maximum value of an X coordinate, a minimum value of the X coordinate, a maximum value of a Y coordinate, and a minimum value of the Y coordinate in all the position coordinates, and an aspect ratio of the first display device.

3 . The method according to claim 2 , wherein the determining the area to be annotated according to the maximum value of the X coordinate, the minimum value of the X coordinate, the maximum value of the Y coordinate, and the minimum value of the Y coordinate in all the position coordinates, and the aspect ratio of the first display device, comprises:
determining a pre-selected area according to the maximum value of the X coordinate, the minimum value of the X coordinate, the maximum value of the Y coordinate and the minimum value of the Y coordinate in all the position coordinates, a preset X-direction threshold and a preset Y-direction threshold; in a case where an aspect ratio of the pre-selected area is equal to the aspect ratio of the first display device, determining the pre-selected area as the area to be annotated; in a case where the aspect ratio of the pre-selected area is less than the aspect ratio of the first display device, determining a height of the pre-selected area as a height of the area to be annotated, and determining a width of the area to be annotated according to the height of the pre-selected area and the aspect ratio of the first display device; and in a case where the aspect ratio of the pre-selected area is greater than the aspect ratio of the first display device, determining a width of the pre-selected area as the width of the area to be annotated, and determining the height of the area to be annotated according to the width of the pre-selected area and the aspect ratio of the first display device.

4 . The method according to claim 3 , wherein the determining the pre-selected area according to the maximum value of the X coordinate, the minimum value of the X coordinate, the maximum value of the Y coordinate, and the minimum value of the Y coordinate of all the position coordinates, the preset X-direction threshold and the preset Y-direction threshold, comprises:
determining the maximum value of the X coordinate, the minimum value of the X coordinate, the maximum value of the Y coordinate and the minimum value of the Y coordinate of the position coordinates corresponding to the pre-selected area in the first coordinate system, according to the following formulas:
