Interactive Whiteboard Annotation Track Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interactive whiteboard technologies do not allow for real-time annotation on shared content during screen sharing, leading to a poor user experience as annotations must be made on the originating device, disconnecting the annotator from the shared content.
Innovation Solution
An interactive whiteboard system that establishes a data connection with external devices, enabling the display of shared content and synchronous annotation tracking, allowing users to annotate and track changes on the interactive whiteboard itself, independent of the originating device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen sharing is implemented on interactive whiteboard, then content can be displayed and shared with participants, but annotation capability is lost because annotations must be made on the originating device instead of the whiteboard
Solution Approach 1:
The patent introduces an intermediary annotation tracking mechanism that bridges the originating device and the interactive whiteboard. This mediator receives annotation commands from the originating device, processes them, and displays corresponding annotation tracks on the whiteboard, enabling annotation capability without requiring direct modification of the shared content source
Solution Approach 2:
The system creates a visual copy of the annotation process by displaying annotation tracks on the interactive whiteboard that mirror the annotation actions performed on the originating device. This copying approach allows participants to see annotations in real-time on the whiteboard without modifying the original shared content
2Ease of operation
If annotations are made on the originating device during screen sharing, then annotation functionality is maintained, but user experience deteriorates because the annotator is disconnected from the shared content display
Solution Approach 1:
The patent adds a new visual dimension to the screen sharing experience by introducing annotation tracks that appear on the interactive whiteboard display. This dimensional addition allows annotations to be visualized in the shared content space, bringing the annotator back together with the content while maintaining the ability to annotate from the originating device
Solution Approach 2:
The system provides real-time feedback by displaying annotation tracks on the interactive whiteboard that correspond to annotation commands received from the originating device. This feedback loop ensures that annotations are visible to all participants in the meeting, maintaining connection between the annotator and the shared content
Data Source
AI summary
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.
