Controller Segmentation for Extended Display GUI Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image transfer systems, users face difficulties in stopping image transfer operations due to the graphical user interface (GUI) becoming invisible, making it hard to manage projections when the GUI is initially displayed on an extended screen rather than the main display.
Innovation Solution
An information processing apparatus with a communication interface and controller that transmits an extended display image to a display apparatus, allowing the GUI to remain visible and operable even when stopping image transfer, ensuring the user interface is displayed on the main screen if an instruction is input via the user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the GUI is displayed on the extended display to allow image transfer operations, then image transfer functionality is improved, but the GUI becomes invisible when stopping image transfer making operations impossible
Solution Approach 1:
The display is segmented into two independent regions: the extended display region for image transfer operations and the main display region for GUI visibility. The controller maintains separate control for each region, ensuring that stopping image transfer on the extended display does not affect GUI visibility on the main display. This spatial segmentation resolves the contradiction by allowing both functions to coexist without interference.
Solution Approach 2:
The main display acts as an intermediary between the user and the extended display. When image transfer stops on the extended display, the controller uses the main display as a fallback to show the GUI, ensuring continuous operability. This intermediary mechanism prevents the harmful effect of GUI invisibility while preserving the benefits of extended display operations.
2Adaptability or versatility
If the GUI is displayed on the extended display for presentation purposes, then presentation functionality is improved, but the user cannot view or operate the GUI when image transfer stops
Solution Approach 1:
The display system is segmented into presentation function (extended display) and control function (main display). The controller independently manages each segment, allowing the extended display to show presentation content while the main display maintains GUI visibility for user operations. This segmentation enables the system to adapt to different operational states without losing usability.
Solution Approach 2:
The solution moves the GUI from the extended display dimension to the main display dimension. By changing the spatial dimension where the GUI is rendered, the system allows users to interact with controls while viewing presentations on the extended display. This dimensional relocation resolves the conflict between presentation versatility and operational ease.
3Productivity
If image transfer is stopped while GUI is on extended display, then projection control is improved, but the projection plane becomes no-signal making operations impossible
Solution Approach 1:
The main display serves as an intermediary information channel when the extended display becomes unavailable. When image transfer stops and the extended display shows no-signal, the controller redirects GUI information to the main display, preventing information loss. This intermediary mechanism preserves operational capability while maintaining projection control efficiency.
Solution Approach 2:
The controller continuously monitors the state of the extended display and adjusts GUI rendering accordingly. When image transfer stops and the extended display cannot show content, the system provides feedback by displaying the GUI on the main display instead. This feedback mechanism ensures that operational information is never lost, maintaining both productivity and information availability.

AI summary
An information processing apparatus which displays an image on a display, comprises a communication interface configured to communicate with a display apparatus, and a controller configured to transmit an extended display image to be displayed on the display apparatus to the display apparatus via the communication interface, the extended display image being different from the image displayed on the display. While a user interface capable of accepting operations related to the extended display image is displayed together with the extended display image on the display apparatus, the controller causes the user interface to be displayed on the display if an instruction to stop transmission of the extended display image is input via the user interface.
