Presentation Display System for Simultaneous Slide and Note Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a laptop computer is connected to an interactive flat panel or projector for screen mirroring, neither the interactive flat panel nor the laptop can display speaker notes simultaneously with the slides, making it difficult for the speaker to view notes during a presentation.
Innovation Solution
A display system and method that allows a first mobile device to display slides and a second mobile device to display speaker notes by executing a screen mirroring program, where the display apparatus forwards speaker notes to the second mobile device while displaying the slide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If screen mirroring is used to display slides on an interactive flat panel, then the slide presentation can be displayed on a large screen, but the speaker notes cannot be displayed on either the interactive flat panel or the laptop computer
Solution Approach 1:
The display system is segmented into multiple independent display units: the interactive flat panel displays slides while the laptop computer displays speaker notes. This segmentation allows different content to be displayed on different devices simultaneously, resolving the contradiction between large screen display area and speaker notes visibility.
Solution Approach 2:
The system introduces an intermediary mechanism where the laptop computer acts as a separate display device for speaker notes, while the interactive flat panel serves as the primary slide display. This intermediary arrangement enables both slides and speaker notes to be visible to the speaker without requiring them to be displayed on the same device.
2Ease of operation
If speaker notes are displayed on the same device as slides during screen mirroring, then the speaker can view notes, but the display system becomes more complex
Solution Approach 1:
The laptop computer serves multiple functions: it originally displays slides locally, and now also displays speaker notes. This multi-functionality allows the system to provide speaker notes accessibility without adding significant complexity, as the same device performs multiple display roles.
Solution Approach 2:
The system creates a copy of the presentation content separation mechanism where slides and speaker notes are displayed on different devices. This copying approach allows the speaker to access notes on a separate device while maintaining the original slide display functionality, avoiding the need for complex integrated systems.
3Adaptability or versatility
If the interactive flat panel displays both slides and speaker notes through screen mirroring, then all content is available on one device, but the speaker cannot view speaker notes when the flat panel shows slides
Solution Approach 1:
The display content is segmented and distributed to different devices: the interactive flat panel displays slides while the laptop computer displays speaker notes. This segmentation maintains adaptability by allowing different content types on different devices while ensuring speaker notes visibility for the speaker.
Solution Approach 2:
The system transitions from a single-device display dimension to a multi-device display dimension. By distributing content across the interactive flat panel and laptop computer, the system creates a spatial dimension for content separation, allowing slides and speaker notes to coexist without interfering with each other's visibility.
Data Source
AI summary
A display system and a displaying method are disclosed. The method includes: selecting a first presentation file from at least one presentation file by the first computing device of the first mobile device according to a first user command, obtaining a first slide and first speaker notes corresponding to the first slide from the first presentation file, and transmitting the first slide and the first speaker notes to the display apparatus; forwarding the first speaker notes by the display apparatus to the second computing device of the second mobile device; and displaying the first slide by the first display device of the first mobile device, displaying the first slide by the display apparatus, and displaying the first speaker notes by the second display device of the second mobile device.
