Multi-Board Presentation System with Panel Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pen-based electronic systems face challenges such as the 'collision problem' where moderator additions collide with private annotations from participants, lack of moderator awareness of participant actions, and limited mobility and space for instructors in classroom settings, hindering effective collaboration and interaction.
Innovation Solution
A multi-board input and display system with a server and computer-enabled display devices allows for a master display device to synchronize panels across multiple interactive boards, enabling mobility and interactive panel management, with features like shadowed feedback to prevent collisions and allow participants to input on any panel, maintaining privacy and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single whiteboard is used for display, then the system is simple to manage, but the instructor lacks mobility and classroom coverage is limited
Solution Approach 1:
The system divides a single large whiteboard into multiple smaller display boards distributed around the classroom. Each board can be independently controlled and displayed on participant devices, allowing instructors to move freely while maintaining visual connectivity with students at different locations.
Solution Approach 2:
The system transitions from a two-dimensional single board display to a multi-dimensional distributed display architecture. Multiple boards are positioned at different spatial locations, and participant devices provide an additional digital dimension for accessing and annotating board content from any location.
2Reliability
If moderator content is displayed on all boards simultaneously, then content consistency is maintained, but participant annotations collide with moderator additions
Solution Approach 1:
The system captures participant annotations as snapshots before moderator content is added. These snapshots are stored and can be reviewed or restored if collisions occur, allowing the system to prevent loss of participant work while maintaining the ability to add new moderator content.
Solution Approach 2:
The system provides feedback to moderators about existing participant annotations before allowing new content to be displayed. This feedback mechanism alerts moderators to potential collisions and enables them to adjust their content placement or review existing annotations first.
3Adaptability or versatility
If participant annotations are made on dynamic moderator content, then interactive learning is enhanced, but annotation privacy is compromised when content changes
Solution Approach 1:
The system creates snapshot copies of participant annotations at specific moments in time. These snapshots preserve the original annotation state and can be displayed separately from the dynamic moderator content, allowing participants to maintain private notes while still engaging with evolving instructor material.
Solution Approach 2:
The system implements dynamic panel management where participant annotations are associated with specific content panels rather than being permanently fixed. When panels are updated or replaced, annotations can be preserved in their original context or transferred to new panels, maintaining both interactivity and privacy throughout the instructional flow.

AI summary
A multi-board presentation system has a plurality of interactive boards connected to and controlled by separate computers that are in communication with one another through a server. The multi-board system utilizes a multi-machine interface that runs concurrently on each interactive board/computer providing heterogeneous input and output capabilities. Each interactive board may be assigned or associated with an offset value that allows for various schemes of display of panels of content on the different interactive boards. Such schemes may be operated manually by a moderator or automatically via the system. A portable interactive tablet may be part of the multi-board system which interfaces with the plurality of interactive boards through the server. The present multi-board system may also include a plurality of interactive participant tablets that are in communication with the array of interactive boards. Each interactive user tablet allows the participant to select which panel of content to display on their interactive tablet. Each interactive participant tablet allows the participant to synchronize display of one or panels of content thereon as displayed on one or more of the interactive boards. Moreover, each interactive participant tablet accepts participant input that is displayable on an interactive board displaying the same panel of content, with the participant input optionally being masked or obscured.
