Electronic Whiteboard Track Grouping for Message Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic whiteboards fail to recognize multiple writing actions as part of a single object, leading to inefficient processing and increased communication resource usage.
Innovation Solution
An electronic whiteboard system that groups multiple writing tracks into a single object using a track grouping mode, executed through specific operation commands, reducing the message amount and enhancing transmission speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple writing tracks are treated as separate line objects, then each writing action is independently recognized, but the system cannot perform uniform subsequent processing and message amount increases
Solution Approach 1:
The patent merges multiple writing tracks that belong to the same graphic object into a single line object by detecting continuity between tracks and grouping them together. This combining approach reduces the total message amount while maintaining accurate recognition of the underlying writing content, directly resolving the contradiction between recognition accuracy and message volume.
2Reliability
If multiple writing tracks are treated as separate line objects, then each track is independently processed, but communication transmission resources are wasted and transmission speed decreases
Solution Approach 1:
By merging multiple writing tracks into a single line object when they belong to the same graphic object, the system reduces the number of separate processing operations and message transmissions required. This improves transmission speed and resource efficiency while maintaining processing reliability through continuous track detection and grouping mechanisms.
3Device complexity
If traditional electronic whiteboard system processes each writing action separately, then simple processing is achieved, but uniform subsequent processing of text or graphic objects is impossible
Solution Approach 1:
The patent implements a dynamic processing approach where the system automatically detects whether writing tracks are continuous and belong to the same graphic object, then adaptively groups them accordingly. This dynamic detection and grouping mechanism enables uniform subsequent processing of graphic objects while maintaining simple processing for isolated tracks, resolving the contradiction between processing simplicity and versatility.
