Display Scaling for Cross-Orientation Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paperless conference systems face challenges in synchronizing display screens between terminals with different orientations and aspect ratios, leading to inconsistent viewing experiences across devices.
Innovation Solution
An information processing apparatus that receives information about a specified display area and scales it, along with its peripheral image, to ensure the display area fits within the display field of the terminal, maintaining the aspect ratio and allowing for maximum magnification or adjusted scaling to accommodate varying screen orientations and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display screen synchronization is implemented between terminals with different orientations and aspect ratios, then viewing consistency is improved, but display adaptation complexity increases
Solution Approach 1:
The system dynamically adjusts display parameters including scaling factors, position coordinates, and aspect ratio ratios based on the terminal's orientation and display field characteristics. By changing these parameters adaptively, the system achieves consistent display synchronization across different terminal configurations without requiring complex hardware modifications
Solution Approach 2:
The display adaptation process is made dynamic by continuously detecting terminal orientation and display field information, then adjusting the scaling and positioning of displayed content in real-time. This dynamic adjustment allows the system to handle varying terminal configurations flexibly, maintaining synchronization consistency while managing complexity through automated adaptive behavior
2Ease of operation
If display area is scaled to fit within display field, then viewing experience is optimized, but image quality may deteriorate
Solution Approach 1:
The system scales the display area to fit within the display field while preserving the original aspect ratio, using partial scaling rather than full compression. This approach ensures the content fits properly on different terminal sizes and orientations while maintaining sufficient image quality by avoiding excessive compression, thus optimizing viewing experience without severely degrading image quality

AI summary
An information processing apparatus for displaying a specified display area of target data in a display unit, the target data being shared with another information processing apparatus. The information processing apparatus includes: a reception unit that receives information indicative of the specified display area specified in the another information processing apparatus; and a display controlling unit that scales the specified display area and an image in a peripheral portion of the specified display area and displays the specified display area and the image in the display unit such that the specified display area is included in a display field of the display unit based on the received information indicative of the specified display area and information about the display field of the display unit.
