Image Display Apparatus File Selection Screen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display apparatuses for presentations often inadvertently display unwanted information when projecting the computer screen, which can be undesirable during file selection processes.
Innovation Solution
An image display apparatus with a candidate information obtaining unit, selection screen display unit, and presentation execution instruction unit that allows for the selection of presentation subject files without displaying the computer drawing screen, thereby suppressing the display of unnecessary information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the computer drawing screen is displayed on the image display apparatus, then the user can see the computer screen content, but unwanted information may be displayed during file selection
Solution Approach 1:
The display content is segmented into two distinct modes: a file selection screen showing only presentation files and a drawing screen showing the computer screen. The system transitions between these segments based on the operational state, ensuring that unwanted information is not displayed during file selection while still allowing full computer screen visibility during presentation mode.
2Object-affected harmful factors
If the selection screen is displayed without the computer drawing screen, then unwanted information is suppressed, but the user cannot see the computer screen during file selection
Solution Approach 1:
The display system dynamically adjusts its content based on the operational phase. During file selection, only the selection screen is displayed to suppress unwanted information. When a file is selected and the presentation mode is activated, the system transitions to displaying the computer drawing screen. This dynamic switching resolves the contradiction by adapting the display content to the current operational needs.

AI summary
A computer connectable image display apparatus for presentation is provided. The image display apparatus has a candidate information obtaining unit, a selection screen display unit, a presentation execution instruction unit, and a drawing screen display unit. The candidate information obtaining unit obtains selection candidate information generated by the computer relating selection candidates for a presentation subject file. The selection screen display unit generates and displays a selection screen for selecting the presentation subject file based on the selection candidate information. The presentation execution instruction unit makes the computer to execute the selected presentation subject file by sending selection results with the selection screen. The drawing screen display unit captures and displays a computer drawing screen drawn by the computer. The image display apparatus displays the selection screen without displaying the computer drawing screen when a connection with the computer is established, and displays the computer drawing screen when drawing by the computer executing the selected presentation subject file is started.
