Snapshot Control for Seamless Electronic Whiteboard Annotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual collaboration tools face difficulties in seamlessly switching between live application sharing and whiteboard annotation, leading to interruptions in the presentation flow due to the inability to run these functions simultaneously, requiring users to stop live application sharing and manually transfer snapshots, which is time-consuming and burdensome.
Innovation Solution
A system and method that allows users to take snapshots of active applications and transfer them directly to a linked electronic whiteboard for annotation, enabling seamless transitions and eliminating the need for pre-prepared snapshots, with a snapshot control accessible during live presentations and a toolbar for snapshot management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users stop live application sharing to use whiteboard annotation, then whiteboard functions can be used, but the presentation flow is interrupted and time is lost
Solution Approach 1:
The patent combines live application sharing and whiteboard annotation into a single integrated interface. Users can share their desktop or application while simultaneously accessing whiteboard tools through a toolbar overlay, eliminating the need to switch between separate applications or stop sharing. The whiteboard toolbar appears as an overlay on top of the shared content, allowing both functions to operate concurrently.
Solution Approach 2:
The system maintains continuous live application sharing throughout the entire presentation session. The sharing stream never stops, and the whiteboard annotation function is layered on top of this continuous stream. This allows the presenter to maintain the live sharing connection while intermittently activating whiteboard tools for annotations, ensuring uninterrupted content delivery to participants.
2Ease of operation
If users manually transfer snapshots from application sharing to whiteboard, then annotation is possible, but the process is complex and time-consuming
Solution Approach 1:
The patent extracts the snapshot capture and transfer process into a simplified single-click operation. Instead of manually copying and pasting through multiple applications, the system provides a dedicated snapshot button in the toolbar that directly captures the current shared screen state and places it on the whiteboard. This extraction of the complex transfer process into a single atomic action dramatically reduces the steps required.
Solution Approach 2:
The system introduces an intermediary snapshot mechanism that sits between the live application sharing and the whiteboard. When users click the snapshot button, this intermediary component captures the current shared display state and automatically transfers it to the whiteboard canvas. This intermediary layer abstracts away the complexity of manual transfer operations and provides a seamless bridge between the two functions.
3Loss of time
If pre-prepared snapshots are saved to storage, then loading time is reduced, but preparation burden increases and snapshots may not match live demonstration
Solution Approach 1:
The system performs preliminary snapshot capture on-demand during the presentation rather than requiring advance preparation. The snapshot button captures the current shared screen state at the moment it is clicked, ensuring the snapshot exactly matches what is being demonstrated live. This preliminary action is taken at the point of need rather than in advance, eliminating the mismatch problem while maintaining quick capture speed.
Data Source
AI summary
A system and method is provided for enabling collaborative electronic presentations and annotation of graphic information. The method includes the operation of taking a snapshot of an active application. A snapshot can be initiated by a user accessible snapshot control. The snapshot of the active application can be transferred to the electronic whiteboard in response to activation of the snapshot control. A further operation is storing the snapshot in a whiteboard sheet of the electronic whiteboard. Each loaded snapshot may be stored in a separate whiteboard sheet in order to provide a plurality of whiteboard sheets. Another operation can be enabling graphical annotation of the plurality of whiteboard sheets in the whiteboard annotation area by the user.
