Solution Overview
Problem
Existing electronic meeting tools face challenges such as complexity in networking infrastructure, high user expertise requirements, lack of participation, inefficient display management, and difficulties in connecting devices to projectors, leading to unproductive and time-consuming meetings.
Innovation Solution
A method for displaying images on multiple devices using a shared memory canvas that maintains aspect ratio and resolution, allowing participants to add or remove sources democratically, and using a zero-footprint screen scraping technology for seamless content sharing without installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional presentation software is used with a single presenter, then the presentation can be controlled centrally, but participant participation and collaboration are limited
Solution Approach 1:
The system divides the presentation control into multiple independent participant workspaces, each capable of displaying and controlling their own content. The virtual whiteboard is segmented into multiple regions where different participants can contribute simultaneously, eliminating the single-point control bottleneck while maintaining system manageability through modular architecture.
Solution Approach 2:
The virtual whiteboard serves multiple functions simultaneously: it acts as a presentation display, a collaboration canvas, a content aggregation space, and a shared annotation area. This multi-functionality allows the system to support both centralized presentation and distributed collaboration without requiring separate systems, resolving the contradiction between participation and complexity.
2Adaptability or versatility
If multiple devices are connected to a single projector, then content sharing is enabled, but connection time and setup complexity increase
Solution Approach 1:
The system replaces physical cable connections with wireless network-based communication. Devices connect to the projection system through the network rather than requiring direct physical links, eliminating the time-consuming process of plugging and unplugging cables while maintaining versatile device connectivity through standard network protocols.
Solution Approach 2:
The system performs preliminary network discovery and device pairing before the meeting starts. Devices are pre-configured with network credentials and connection parameters, so when the meeting begins, they can join the virtual whiteboard session immediately without requiring on-the-spot connection setup, thus reducing connection time while maintaining adaptability.
3Ease of operation
If screen content is captured and transmitted over network, then remote display is enabled, but security risks and configuration complexity arise
Solution Approach 1:
The system introduces a trusted local gateway device as an intermediary between the participant devices and the network. Screen content is captured and transmitted through this local gateway rather than directly over the network, which filters and secures the data transmission. This intermediary approach simplifies display setup by handling connections automatically while mitigating security risks through localized processing and controlled network exposure.
4Area of stationary object
If display content is scaled to fit multiple screens, then screen real estate is optimized, but aspect ratio distortion occurs
Solution Approach 1:
Instead of scaling images in two dimensions which causes distortion, the system arranges multiple scaled-down versions of the same content across multiple display screens in a spatial distribution pattern. Each screen displays a portion of the overall content layout, maintaining the original aspect ratio on each screen while collectively utilizing the full display area available across the multi-screen configuration.
