Display Apparatus Multi-Indicator Storage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic blackboard systems, the existing techniques for cut and paste operations using multiple indicators suffer from data confusion, where the intention to paste a virtual object is often misinterpreted due to shared storage regions, leading to incorrect pasting of virtual objects.
Innovation Solution
A display apparatus with separate storage regions and detection sections for each indicator, allowing independent cut and paste operations, and an optional switching mechanism for shared operation modes, ensuring accurate pasting based on user intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a shared storage region (clip buffer) is used for multiple indicators, then the device complexity is reduced, but data confusion occurs and pasting accuracy deteriorates
Solution Approach 1:
The shared storage region is segmented into multiple independent storage regions, with each region corresponding to a specific indicator. This segmentation prevents data confusion between indicators while maintaining manageable system complexity through organized data separation.
2Reliability
If separate storage regions are provided for each indicator, then pasting accuracy is improved, but device complexity increases
Solution Approach 1:
The storage control section provides universal management functionality that works across all storage regions. This multi-functional approach handles cut, copy, and paste operations uniformly for any indicator, reducing overall system complexity despite having multiple storage regions.
3Ease of operation
If independent storage regions are used for each indicator, then cut and paste operations become independent and accurate, but the storage management complexity increases
Solution Approach 1:
The storage control section merges the management of multiple storage regions into a single integrated control unit. This combining approach handles all cut, copy, and paste operations centrally, simplifying storage management while maintaining independence of operations for each indicator.

AI summary
A display apparatus includes a first detection section detects the position of a first indicator on the image. A second detection section detects the position of a second indicator on the image. A storage section includes a first storage region corresponding to the first indicator and a second storage region corresponding to the second indicator. The first storage control section stores a first virtual object relating to the first indicator in the first storage region. The second storage control section stores a second virtual object relating to the second indicator in the second storage region. A first pasting section pastes the first virtual object stored in the first storage region to the image according to an operation of the first indicator. A second pasting section pastes the second virtual object stored in the second storage region to the image according to an operation of the second indicator.
