Abstract
The present document discloses an the method of providing annotation track on the content displayed on an interactive whiteboard, an apparatus, a device, and a storage medium. The method of providing annotation track includes: displaying screen sharing data; displaying an annotation track, where the annotation track is generated based on an annotation command or a touch operation; controlling the annotation track to change synchronously with a change of corresponding screen sharing data on a display interface.
Claims20
A method of providing annotation track on the content displayed on a whiteboard, the method comprising:
- displaying a first content of screen sharing;
- receiving a first annotation command, wherein the first annotation command is used for annotating the first content of screen sharing;
- displaying a first annotation track above the first content of screen sharing, wherein the first annotation track is generated based on the first annotation command;
- detecting a first request to turn pages forward, wherein the first request to turn pages forward is used for triggering the first content of screen sharing to turn forward;
- displaying a second content of screen sharing after performing the request;
- detecting a second request to turn pages backward, wherein the second request is used for controlling the second content of screen sharing to turn backward to the first content of screen sharing;
- and
- displaying the first content of screen sharing and the first annotation track after performing the second request.
A computing device for providing annotation track on the content displayed on a whiteboard, the computing device comprising:
- a computer readable storage medium, a display screen with a touch function, and one or more processors;
- wherein the computer readable storage medium is configured to store at least one instruction;
- the at least one instruction, when executed by the one or more processors, causes the computing device to:
- display a first content of screen sharing on the display screen;
- receive a first annotation command, wherein the first annotation command is used for annotating the first content of screen sharing;
- display a first annotation track above the first content of screen sharing, wherein the first annotation track is generated based on the first annotation command;
- detect a first request to turn pages forward, wherein the first request to turn pages forward is used for triggering the first content of screen sharing to turn forward;
- display a second content of screen sharing after performing the first request on the display screen;
- detect a second request to turn pages backward, wherein the second request is used for controlling the second content of screen sharing to turn backward to the first content of screen sharing;
- and
- display the first content of screen sharing and the first annotation track after performing the second request.
A non-transitory readable storage medium having at least one executable instruction stored thereon, when executed by one or more processors of a computing device, causes the processors to perform operations, the operations comprising:
- displaying a first content of screen sharing;
- receiving a first annotation command, wherein the first annotation command is used for annotating the first content of screen sharing;
- displaying a first annotation track above the first content of screen sharing, wherein the first annotation track is generated based on the first annotation command;
- detecting a first request to turn pages forward, wherein the first request to turn pages forward is used for triggering the first content of screen sharing to turn forward;
- displaying a second content of screen sharing after performing the first request;
- detecting a second request to turn pages backward, wherein the second request is used for controlling the second content of screen sharing to turn backward to the first content of screen sharing;
- and
- displaying the first content of screen sharing and the first annotation track after performing the second request.
