Projection Layout Control for Obstacle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content projection systems fail to effectively utilize projection suitable areas when faced with unsuitable areas, leading to reduced visibility of projected content.
Innovation Solution
A content projection control apparatus and method that determines projection unsuitable areas and rearranges content layout by generating arrangement units based on these areas, optimizing the placement of content units within the projection area to avoid unsuitable regions while maximizing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is projected on a wall or surface other than a special projection screen, then multiple people can enjoy content together and usage flexibility is improved, but projection unsuitable areas (such as equipment, clocks, calendars, wall panel connecting members) may appear and reduce content visibility
Solution Approach 1:
The content is divided into multiple arrangement units (e.g., title, body text, images) that can be independently positioned. This segmentation allows the system to place each unit in projection suitable areas while avoiding projection unsuitable areas, thus maintaining content visibility when projecting on walls or surfaces with obstacles.
Solution Approach 2:
The system transitions from fixed horizontal/vertical division to two-dimensional flexible arrangement of arrangement units. By changing the layout dimensionality and freedom of placement, the system can effectively utilize projection suitable areas while circumventing projection unsuitable areas on the projection surface.
2Reliability
If the entire content is horizontally or vertically divided into two halves and placed above and below or left and right of the projection unsuitable area, then content visibility is maintained in projection suitable areas, but projection suitable area utilization is reduced unless the projection unsuitable area extends in a belt-shaped manner
Solution Approach 1:
Content is segmented into multiple arrangement units that can be independently positioned within the projection area. This allows flexible distribution of content elements across projection suitable areas, maximizing area utilization while avoiding projection unsuitable areas, rather than rigid horizontal/vertical division.
Solution Approach 2:
The system dynamically determines the positions of arrangement units based on the detected projection unsuitable areas. The layout is not fixed but adaptively adjusted to utilize projection suitable areas effectively, improving both content visibility and area utilization.
3Device complexity
If content layout is fixed without considering projection unsuitable areas, then layout simplicity is maintained, but content may be partially projected onto projection unsuitable areas reducing visibility
Solution Approach 1:
The system performs preliminary detection of projection unsuitable areas and pre-calculates optimal positions for arrangement units before projection. This preliminary action ensures content is properly positioned to avoid projection unsuitable areas without requiring complex real-time adjustments during projection.
Solution Approach 2:
The content projection control apparatus automatically detects projection unsuitable areas and adjusts the layout of arrangement units without manual intervention. The system serves itself by autonomously optimizing content placement, balancing layout simplicity with content visibility.

AI summary
To prevent visibility of content from being partially lowered due to existence of a projection unsuitable area while effectively utilizing a projection suitable area. Provided is a content projection control method including the steps of obtaining content data indicating content including a plurality of objects, each object including one or more images or a plurality of characters, obtaining projection area data indicating a projection area, determining a projection unsuitable area, which is not suitable for projection in the projection area, based on the projection area data, generating a plurality of arrangement units from the content indicated by the content data, each arrangement unit including one object or a plurality of adjacent objects, and changing a layout of the arrangement units by determining a projection position of each arrangement unit based on a position of the projection unsuitable area.
