Dynamic Content Layout Switching for External Display Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network screen transfer systems fail to fully utilize the screen resolution of external display devices when transferring images from mobile devices like cellular phones to projectors, resulting in insufficient information display due to differences in content resolution and layout.
Innovation Solution
An information processing apparatus and method that dynamically requests and transmits content from a server based on connection state with the external display device, switching between high and low information/content layouts to optimize display resolution usage, and re-requesting content when the connection state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If screen capture is performed from a mobile device and transmitted to an external display device, then the screen can be displayed on the external device, but the screen resolution of the external display device cannot be fully utilized due to resolution mismatch
Solution Approach 1:
The system changes the resolution parameter of the transmitted content by detecting the resolution of the external display device and selecting or transforming content to match the external device's resolution, thereby fully utilizing the screen resolution of the external display device
Solution Approach 2:
The system dynamically adjusts the content transmission based on the detected connection state and resolution information. When an external display device is detected, the system switches to transmitting high-resolution content suitable for the external device, and when not connected, it transmits content optimized for the mobile device screen
2Ease of operation
If content is optimized for mobile device screens, then the content is suitable for small screen display, but the amount of information displayed is insufficient when projected on external display devices
Solution Approach 1:
The system changes the information density parameter of the content by selecting different content versions (high information layout vs. low information layout) based on the display device type, ensuring that external display devices receive content with sufficient information while mobile devices receive optimized content
3Extent of automation
If the system automatically detects connection state and switches content layouts, then optimal display is achieved, but the system complexity increases
Solution Approach 1:
The system performs self-detection of the connection state and automatic selection of appropriate content layouts without requiring user intervention. The mobile device itself detects whether an external display device is connected and automatically switches between high and low information layouts
Solution Approach 2:
The system uses feedback from the connection state detection to automatically adjust the content transmission. By detecting the presence of external display devices and their resolution characteristics, the system feeds this information back to the content selection mechanism to choose the appropriate layout

AI summary
An information processing apparatus controls image transfer to display an image by projection while making full use of a screen resolution of an external display device without requiring a user to take time and trouble. A server sends a plurality of contents including a first and second content differing in amount of information and associated with each other. To request any one of the contents with the external display device not connected, the server is notified of information for receiving the first content, and to request the content with the external display device connected, the server is not notified of the information. In a case where a state of connection with the external display device changes while the content is displayed, the content is requested from the server again, which determines whether to notify the server of the information in accordance with the state of connection after the change.
