Floating Window Speaker Notes for Mirrored Slides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a mobile device is connected to a display apparatus via screen mirroring, the mobile device cannot simultaneously display slides and speaker notes, limiting the user's ability to reference notes during presentations.
Innovation Solution
A display system and method where the mobile device, connected to a display apparatus, uses a floating window on its display to show speaker notes while displaying slides on the connected apparatus, allowing users to view notes alongside the presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If screen mirroring is used to display slides on the display apparatus, then the slide can be displayed on the connected device, but the speaker notes cannot be displayed simultaneously on either the mobile device or the display apparatus
Solution Approach 1:
The display content is segmented into two separate channels: the display apparatus shows the slide while the mobile device's local display shows the speaker notes in a floating window. This segmentation allows both pieces of information to be displayed simultaneously on different devices, resolving the contradiction where screen mirroring could only show one content at a time.
Solution Approach 2:
The mobile device acts as an intermediary that receives the slide content from the display apparatus via screen mirroring, then redistributes the content to two different displays: the slide goes to the display apparatus while the speaker notes are routed to the mobile device's own display in a floating window overlay.
2Loss of information
If the floating window displays speaker notes, then the notes are visible on the mobile device, but the window may obstruct part of the slide display
Solution Approach 1:
The floating window is designed with semi-transparent or translucent properties, allowing the slide content to remain partially visible through the window area. This local quality modification ensures that the speaker notes are readable while the underlying slide content remains accessible, resolving the area conflict between notes and slides.
3Area of stationary object
If the floating window is made transparent to show slide content underneath, then both notes and slide are visible, but the text readability may be reduced
Solution Approach 1:
The transparency parameter of the floating window is dynamically adjusted or optimized to find the best balance between showing the slide content underneath and ensuring the speaker notes remain readable. This parameter change resolves the contradiction by tuning the visual properties to satisfy both requirements.

AI summary
A display system and a display method are provided. The display system includes a display apparatus and a mobile device having a computing device and a display. The method includes: selecting a first presentation file from at least one presentation file according to a first user command and obtaining a first slide and first speaker notes corresponding to the first slide from the first presentation file by the computing device of the mobile device, wherein the display apparatus is for displaying the first slide and the display is for displaying a floating window and the first slide, and the floating window at least partially covers the first slide displayed on the display, wherein the floating window is for displaying the first speaker notes.
