Master-Slave Presentation System for Collaborative Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large-scale presentation systems lack efficient methods for intuitive and seamless information sharing among conference attendees, both within a conference space and remotely, particularly in configuring and controlling multiple presentation units for collaborative activities.
Innovation Solution
A system comprising a master presentation unit and slave units, where the master unit identifies and configures slave units through unique identifiers, enabling the transfer of images and control interfaces for collaborative activities, allowing for wireless communication and network linking to facilitate simultaneous viewing and editing across multiple locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a master-slave presentation system is implemented for information sharing, then information sharing capability is improved, but system complexity increases
Solution Approach 1:
The presentation system is segmented into a master presentation unit and multiple slave presentation units. The master unit handles configuration, control, and coordinate transformation, while slave units handle display and local interaction. This segmentation allows the system to support multiple display locations and configurations without requiring each unit to be fully independent, thus improving information sharing capability while managing system complexity through division of labor.
2Adaptability or versatility
If multiple presentation units are configured for collaborative activities, then collaborative capability is improved, but configuration complexity increases
Solution Approach 1:
Slave presentation units automatically receive their configuration parameters (display coordinates, transformation matrices, scaling factors) from the master unit through wireless communication. The system performs self-configuration without requiring manual setup at each slave unit, reducing configuration complexity while enabling collaborative activities across multiple display locations.
Solution Approach 2:
The master unit maintains a model of the conference space geometry and uses feedback from slave unit positions to automatically calculate and update coordinate transformation parameters. This feedback mechanism allows the system to adapt to different physical arrangements of display units while maintaining consistent content presentation across all locations.
3Speed
If real-time image transfer is implemented between units, then information sharing speed is improved, but data transmission requirements increase
Solution Approach 1:
The system transforms image coordinates and geometric parameters from the master unit's coordinate system to each slave unit's local coordinate system using mathematical transformation matrices. This parameter transformation allows real-time image transfer without requiring massive data transmission, as only the transformed coordinate parameters need to be communicated rather than complete image datasets to each location.
