Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional displays require high processing capacity and are expensive due to complex eye-tracking and image correction processes, leading to incomplete image viewing during the time it takes to establish accurate three-dimensional image presentation.
Innovation Solution
A three-dimensional image observation system with a predefined viewing area and a guide means, such as a guide frame or indicator displays, that visually guides the observer's eyes to the viewing area, eliminating the need for complex eye-tracking and image correction processes, thereby reducing costs and ensuring accurate three-dimensional image viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If eye-tracking and image correction processes are implemented to ensure accurate three-dimensional image viewing, then viewing accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-defining the viewing area and pre-configuring the light ray controller to emit light rays specifically for this predetermined area. This eliminates the need for real-time eye tracking and dynamic image correction, as the system is already optimized for the specific viewing zone before the observer arrives. The viewing area is established in advance with appropriate light ray emission patterns, simplifying the overall system while maintaining viewing accuracy.
2Measurement precision
If complex eye-tracking and image correction processes are implemented, then viewing accuracy is improved, but processing capacity requirements and cost increase
Solution Approach 1:
The system performs preliminary configuration by pre-defining the viewing area and pre-calculating the appropriate light ray emission patterns for this specific zone. This eliminates the need for computationally intensive real-time eye tracking and dynamic image correction processes. The light ray controller is pre-programmed with the viewing area parameters, allowing it to operate with minimal processing capacity requirements while maintaining high viewing accuracy within the predetermined zone.
3Measurement precision
If multiple processing steps are performed sequentially to present three-dimensional images, then image accuracy is improved, but time required for image presentation increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing the viewing area and pre-configuring the light ray emission patterns before the observer views the three-dimensional image. This eliminates the need for sequential processing steps including real-time eye tracking, image data transfer, and dynamic correction. The system transitions to a more direct mode where pre-configured light rays are emitted immediately, significantly reducing the time required for image presentation while maintaining accuracy within the predetermined viewing zone.

AI summary
A three-dimensional image observation system includes a three-dimensional display (100) and a guide frame (410). The three-dimensional display is constituted by a light ray controller (1), a plurality of light ray generators (2), a control device (3) and a storage device (4). Further, the three-dimensional display (100) is provided at a table (5). In the three-dimensional display (100), the area where eyes of observers (10) are to be positioned when the observers observe a three-dimensional image is predefined as a viewing area (500), and the guide frame (410) visually guides the eyes of the observers (10) from the outside of the viewing area (500) to the inside of the viewing area.
