Pen-Based Object Data Transfer for Electronic Whiteboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interactive whiteboard systems require significant time and effort to transfer object data between classrooms, as users must manually input and save data on each board, lacking efficient methods for seamless data sharing across multiple electronic whiteboards.
Innovation Solution
A display system that includes a control unit and an input device capable of communicating to store and transmit object data, allowing for easy input and sharing of data between display devices through a pen-like input device that performs copy and paste operations, enabling data to be saved and displayed on multiple boards without the need for extensive manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If object data is saved on each electronic whiteboard separately, then data can be displayed on individual boards, but significant time and effort is required to input and transfer data between classrooms
Solution Approach 1:
The patent implements a copy-paste mechanism where object data can be copied from one electronic whiteboard to another using a pen device. The pen stores copied data in its storage unit and can paste it to target whiteboards, eliminating manual re-input and significantly reducing data transfer time between classrooms.
Solution Approach 2:
The pen device serves as an intermediary between electronic whiteboards, enabling data transfer without direct connection between boards. The pen's storage unit acts as a temporary repository, allowing users to copy data from one board, transport it physically, and paste it to another board, thus facilitating efficient data sharing across multiple locations.
2Reliability
If the entire screen data is saved to transfer object data between whiteboards, then complete data transfer is achieved, but excessive time and effort are consumed in the saving process
Solution Approach 1:
The patent enables extraction of specific object data from the entire whiteboard screen. Users can select and copy only the necessary object data (such as specific text, images, or diagrams) rather than saving the entire screen, thus reducing the data volume to be transferred and the time required for the saving process while maintaining transfer completeness for the needed content.
Solution Approach 2:
The whiteboard screen is segmented into individual object data elements that can be independently selected, copied, and transferred. This segmentation allows users to extract only the specific objects they need rather than transferring the entire screen, optimizing both data transfer reliability and time efficiency.
3Measurement precision
If manual input of object data is performed on each whiteboard, then data accuracy is maintained, but user effort and time consumption increase significantly
Solution Approach 1:
Instead of manually re-inputting object data on each whiteboard, the patent allows users to copy data from one whiteboard and paste it to another using the pen device. This copying mechanism maintains data accuracy by preserving the original content exactly as it appears, while dramatically reducing user effort and time consumption compared to manual input.
Solution Approach 2:
The system enables self-service data transfer where the copied data automatically retains its formatting and content properties. The paste operation automatically integrates the copied object data into the target whiteboard environment, eliminating the need for manual re-formatting or re-input while ensuring data accuracy is maintained.

AI summary
A pen stores a plurality of pieces of object data, and a control device displays the plurality of pieces of object data stored in the pen in a first display area of a touch panel display device as thumbnails in response to a paste operation performed by using the pen. The control device displays, in a second display area of the touch panel display device, a piece of object data selected from among the plurality of pieces of object data displayed as thumbnails in response to a selection operation performed by using the pen.
