Solution Overview
Problem
Conventional image display systems in mobile objects, such as vehicles, are limited by fixed positions and sizes, often blocking views and inducing motion sickness, and fail to adapt to varying environments.
Innovation Solution
An image display system combining a transparent screen, light control film, and projection device, allowing adjustable transparency and instant switching between transparent and non-transparent states, with sensors to optimize viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large display is set in a mobile object, then the viewing environment is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent applies dynamics by making the display transparency adjustable rather than fixed. The display can switch between transparent and non-transparent states, allowing the system to adapt to different viewing conditions and environments within the mobile object, thereby improving the viewing environment without requiring multiple fixed displays of different sizes
Solution Approach 2:
The patent changes the transparency parameter of the display dynamically. By controlling the transparency level, the system can optimize viewing conditions for different scenarios (e.g., daytime vs nighttime, different seating positions) without changing the physical size or position of the display, thus avoiding increased device complexity
2Device complexity
If the display position is fixed, then the device complexity is reduced, but the adaptability to varying environments deteriorates
Solution Approach 1:
The patent makes the display transparency dynamic rather than fixed. The display can adjust its transparency level in response to different environmental conditions, maintaining a simple fixed physical installation while achieving high environmental adaptability through dynamic parameter adjustment
Solution Approach 2:
The patent implements feedback control where the display transparency is adjusted based on detected viewing conditions. Sensors detect environmental parameters and provide feedback to the control system, which then adjusts the display transparency accordingly, enabling automatic adaptation to varying environments without complex manual configuration
3Loss of information
If a non-transparent display is used, then the information visibility is improved, but the view blocking increases
Solution Approach 1:
The patent applies dynamics by making display transparency adjustable. The display can switch between transparent and non-transparent states based on the need for information display, allowing the system to provide full information visibility when needed while maintaining clear views when information display is not required, thus eliminating the need to choose between these conflicting requirements
4Loss of information
If the display size is increased, then the information display capability is improved, but the space requirements and device complexity increase
Solution Approach 1:
The patent changes the transparency parameter of the display to enhance information display capability without increasing physical size. By optimizing transparency levels and using projection technology, the system can display information effectively on a smaller surface area, avoiding the need for large displays while maintaining information display capability

AI summary
An information processing device includes an acquisition unit that acquires a detection result on light outside a mobile object, an analyzer that determines a position of projection of content in the mobile object based on the detection result on the light outside the mobile object, and a display controller that performs control on projection of the content onto the determined position of projection.
