Image Display Apparatus Multi-User Interaction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conference systems restrict participants from interacting with and sharing images displayed on a screen, as they can only view the image projected by a presenter, limiting collaborative interactions.
Innovation Solution
An image display apparatus and method that combines remote operation signals from multiple input devices, allowing participants to contribute to and share the same image by storing and combining signals from different devices into a single output image, enabling multiple users to operate and view the same image simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single presenter uses a pointer to control the screen, then the presenter can operate the presentation, but participants cannot interact with or share the image
Solution Approach 1:
The pointer device is designed to serve multiple functions: it can be used by both the presenter for control operations and by participants for interaction and annotation. The same hardware device performs different roles depending on the user and context, eliminating the need for separate devices for each function.
Solution Approach 2:
The patent combines multiple operational modes (presenter control, participant interaction, annotation) into a single unified system. The pointer device, screen, and control unit work together as an integrated system that handles both presentation delivery and participant engagement simultaneously.
2Adaptability or versatility
If multiple laser pointers are used to allow participant interaction, then participants can specify positions on the screen, but it becomes difficult to share images across multiple display apparatuses
Solution Approach 1:
The system creates a copy of the presentation image and transmits it to multiple display apparatuses. Instead of requiring complex coordination between multiple pointers and displays, the same image content is replicated across displays, allowing participants to view and interact with identical content on different devices.
Solution Approach 2:
The control unit acts as an intermediary that receives signals from multiple pointers, processes them, and manages the distribution of image data to various display apparatuses. This mediator coordinates the interactions between multiple users and multiple displays, simplifying the overall system operation.
3Measurement precision
If camera capture and image analysis are used to detect laser pointer positions, then participant pointing can be detected, but the system becomes complex and image sharing across displays is difficult
Solution Approach 1:
The patent replaces the optical-mechanical camera capture and image analysis system with a direct digital signal transmission approach. The pointer device communicates its position data electronically to the control unit without requiring optical capture and computational analysis, significantly simplifying the detection system while maintaining precision.
