Shared Handwriting Display Control With User Edit Authority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing systems face challenges in managing edit authority for handwriting input data across multiple users, leading to inadvertent editing and reduced operational efficiency in collaborative work.
Innovation Solution
A screen sharing system that includes first and second display apparatuses, where the first apparatus sets edit authority for the second apparatus, and the second apparatus restricts editing based on this authority, ensuring only authorized users can edit or view handwriting input data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple users are allowed to edit handwriting input data freely in a screen sharing system, then collaborative work efficiency is improved, but inadvertent editing and operational errors increase
Solution Approach 1:
The system applies preliminary anti-action by establishing edit authority restrictions before collaborative editing begins. The first display apparatus pre-defines which users can edit specific handwriting input data, preventing inadvertent editing by unauthorized users before it can occur. This proactive authority management resolves the contradiction by allowing free collaboration within authorized boundaries while blocking potential harmful edits.
2Reliability
If edit authority restrictions are implemented to prevent inadvertent editing, then editing accuracy is improved, but operational complexity increases
Solution Approach 1:
The system implements self-service by allowing the first display apparatus to automatically set and manage edit authority for handwriting input data without requiring manual intervention from the second display apparatus. The authority management is embedded in the data transmission process itself, where the first apparatus includes authority information with the handwriting data, and the second apparatus automatically enforces these restrictions. This reduces operational complexity while maintaining editing accuracy.
3Reliability
If the first display apparatus sets edit authority for all handwriting input data, then control over collaborative editing is improved, but communication data volume increases
Solution Approach 1:
The system applies local quality by setting edit authority specifically for each handwriting input data element rather than applying uniform control to all data. The first display apparatus includes authority information that is locally attached to each handwriting data element, allowing differentiated control permissions for different users on different data elements. This approach maintains precise editing control while optimizing communication efficiency by only transmitting necessary authority information with each data element.

AI summary
A screen sharing system includes a first display apparatus including first circuitry; and a second display apparatus including second circuitry. Both of the first display apparatus and the second display apparatus display an input screen. The first circuitry of the first display apparatus is configured to receive first hand drafted input data that is input to the first display apparatus, and set an edit authority, of a user of the second display apparatus, for the first hand drafted input data. The second circuitry of the second display apparatus is configured to restrict editing of the first hand drafted input data based on the edit authority of the user set by the first display apparatus.
