Virtual Display Layer for Projector Application Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems that project images from multiple projectors do not support operations beyond layout changes, such as executing application processing, limiting user interaction and functionality.
Innovation Solution
A display control method that reduces a first image generated by an application program, displays it on an actual display, accepts operations on the reduced image, draws a second image corresponding to the operation on a virtual display, and displays the second image using a projector, allowing for execution of processing corresponding to the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display system projects images from multiple projectors, then the display area and visual impact are improved, but the system only supports layout changes and does not support application processing operations
Solution Approach 1:
The patent introduces a virtual display as an intermediary layer between the physical projector and the user's interaction interface. This virtual display receives touch operations, translates them into commands, and executes application processing while projecting the result through the physical projector. This mediator enables complex operations without directly complicating the physical display hardware.
Solution Approach 2:
The patent adds a virtual dimension to the physical display system. Instead of limiting interactions to the physical projector surface, it creates a virtual display layer that can process complex operations. This dimensional extension allows the system to support application processing while maintaining the simplicity of the physical projector hardware.
2Ease of operation
If the display system only supports layout changes, then the system complexity is kept low, but user interaction and functionality are limited
Solution Approach 1:
The virtual display acts as an intermediary that receives user operations and translates them into application commands. This allows users to interact with complex processing functionality through a simplified interface, maintaining ease of operation while enabling versatile processing capabilities.
Solution Approach 2:
The virtual display layer provides multi-functionality by supporting both layout changes and application processing operations through a single interface. This universal layer allows the system to handle diverse operations without requiring separate interaction mechanisms for each function type.
3Adaptability or versatility
If application processing is added to the display system, then functionality is enhanced, but the system complexity increases
Solution Approach 1:
The virtual display serves as an intermediary layer that manages the complexity of application processing. It handles the translation between user operations and application commands, shielding the underlying system architecture from direct complexity while enabling enhanced processing capabilities.
Solution Approach 2:
By adding a virtual dimension to the system architecture, the patent separates the complexity of application processing from the physical display hardware. This dimensional separation allows processing capabilities to be enhanced without proportionally increasing physical system complexity.

AI summary
A display control method includes displaying a first small image generated by shrinking a first image generated by an application program, on an actual display provided in an output device, receiving an operation on the first small image, drawing, on a virtual display, a second image generated by the application program executing processing corresponding to the operation on the first small image, displaying the second image drawn on the virtual display, using a display device, and displaying a second small image generated by shrinking the second image, on the actual display.
