Observer-Aware Display Apparatus for Automatic Projection Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling-hung projector systems require users to interrupt and reconfigure the projection settings each time the environment or user position changes, leading to complex usage and inconvenience, especially in multi-user scenarios.
Innovation Solution
A display apparatus and method that includes an input unit, a display unit, an observer information acquiring unit, a display mode determining unit, and a display control unit to automatically adjust the image display based on the number and positions of observers, determining the optimal display mode and direction to ensure a clear view for all users without unnecessary user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection settings are manually reconfigured each time the environment or user position changes, then the display can be adapted to different scenarios, but the usage becomes complex and inconvenient
Solution Approach 1:
The system automatically detects observer positions and autonomously determines optimal display modes without requiring manual user configuration. The projector uses imaging means to capture the environment, processes the images to identify observer positions, and automatically adjusts projection parameters based on the detected information, enabling the system to serve itself rather than requiring continuous user intervention
Solution Approach 2:
The system establishes a feedback loop where the projection settings are continuously adjusted based on real-time detection of observer positions. The imaging means captures current observer positions, the control unit processes this information, and the projection settings are modified accordingly, creating a closed-loop system that adapts to changing conditions automatically
2Measurement precision
If the system interrupts projection to detect user operations and settings, then accurate detection is possible, but productivity and continuity of useful action are reduced
Solution Approach 1:
The system performs preliminary detection of observer positions using imaging means during or before the projection process, rather than interrupting projection for detection. By capturing images and identifying observer positions in advance or concurrently with projection, the system maintains continuous projection while still achieving accurate detection of user positions and operations
Solution Approach 2:
The system maintains continuous projection operation while simultaneously performing observer detection and position identification. The projection and detection processes occur in parallel or overlapping timeframes, ensuring that the useful action of displaying information continues without interruption while still gathering necessary observational data

AI summary
A display apparatus includes an input unit to input an image signal, a display unit to display an image based on the input image signal, an observer information acquiring unit to acquire the number and positions of observers facing the display object, a display mode determining unit to determine a display mode including a direction of the image to be displayer on the basis of the acquired number and the acquired positions of the observers, and a display control unit to cause the display unit to display an image on the display object in the determined display mode.
