Electronic Whiteboard Bookmark Registration for Section Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic whiteboards save write data as a single file, making it difficult for users to easily access and reuse specific sections marked as important during previous use.
Innovation Solution
An information processing device with a display unit and control unit that allows users to register specific sections of a sheet as bookmarks, enabling easy saving and retrieval by displaying a registration list of preset frames and registering the sheet to a selected frame for bookmarking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If write data is saved as one file, then storage simplicity is improved, but ease of operation deteriorates because users cannot easily access specific sections
Solution Approach 1:
The patent divides the single file into multiple sections by introducing bookmark markers that segment the write data into distinct readable units. Each bookmark creates a named section that can be independently accessed, transforming the monolithic file structure into a segmented organization that maintains storage simplicity while enabling selective access to specific content regions.
2Ease of operation
If conventional bookmark methods are used, then ease of operation is improved, but device complexity increases due to additional data structures
Solution Approach 1:
The patent merges the bookmark registration function with the existing touch panel input mechanism. By utilizing the same touch interface for both writing content and registering bookmarks, the system avoids adding separate complex registration hardware or interfaces. The bookmark data structure is integrated into the existing file format, combining multiple functions within the current system framework rather than adding independent complex subsystems.

AI summary
An information processing device is provided with: a display that displays a sheet on which an object can be arranged; and a controller that controls the display, in which the controller causes the display to display a thumbnail image registration field that lists a plurality of preset registration frames for registering, as a bookmark, the sheet displayed on the display, and registers the sheet displayed on the display, as the bookmark to a registration frame selected by a user from among the plurality of registration frames displayed on the display.
