Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to efficiently combine and adjust the aspect ratio of projection areas when multiple devices are used, leading to inconsistent and non-seamless visual presentations.
Innovation Solution
An electronic device with a sensor, communication circuit, and projection assembly that identifies and adjusts the aspect ratio of combined projection areas by controlling multiple devices to maintain a reference aspect ratio, using a master-slave relationship and edge blending techniques.

Engineering Contradiction Analysis
1Area of moving object
If multiple projection areas are combined to form a larger projection area, then the projection area size is increased, but the aspect ratio consistency and visual seamlessness deteriorate
Solution Approach 1:
The patent segments the visual object into multiple portions corresponding to different projection areas. Each projection area displays a specific segment of the visual content, allowing independent optimization of each segment while maintaining overall aspect ratio consistency. The processor identifies the combination of projection areas and segments the visual object accordingly to ensure proper aspect ratio in each segment.
Solution Approach 2:
The patent applies local quality by adjusting and optimizing the aspect ratio specifically at the boundaries where projection areas are combined. Edge blending techniques are used to smooth transitions at the junctions of adjacent projection areas, ensuring visual seamlessness at critical locations while maintaining overall aspect ratio consistency across the entire combined projection area.
2Area of moving object
If multiple projection areas are combined to form a larger projection area, then the projection area size is increased, but the visual seamlessness and edge blending quality deteriorate
Solution Approach 1:
The patent performs preliminary action by pre-calculating and applying edge blending adjustments before the actual projection. The processor identifies the combination of projection areas in advance and pre-adjusts the visual content segments to account for potential misalignments or gaps at the boundaries. This preliminary adjustment ensures that when the projection areas are combined, the transitions are seamless and visually smooth.
3Manufacturing precision
If the visual object is segmented based on projection area location, then the aspect ratio guidance is improved, but the processing complexity increases
Solution Approach 1:
The patent implements feedback by continuously monitoring the actual projection area combination and adjusting the visual object segmentation accordingly. The processor receives feedback about the detected projection areas and their positions, then dynamically adjusts the segmentation of the visual object to maintain proper aspect ratio guidance. This closed-loop approach ensures accurate aspect ratio management while automating the processing to minimize manual complexity.

AI summary
According to an embodiment, a processor of an electronic device identifies a combination of a first projection area for the electronic device and a second projection area for an external electronic device. The processor displays a portion of a visual object for guiding a reference aspect ratio in the first projection area. The portion is segmented from the visual object based on a location of the first projection area in the combination. The processor adjusts the portion, based on the motion of the electronic device. The processor displays, based on identification of an aspect ratio of the combination being corresponded to the reference aspect ratio, at least portion of media content having the reference aspect ratio in the first projection area.
