Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing demonstration teaching systems face challenges in ensuring the authenticity and interest of content displayed on parent and child terminals, particularly due to positional differences among operators, leading to inconsistent viewing experiences.
Innovation Solution
An image adjustment device and system that dynamically adjusts image pixel arrangements based on pupillary distance and eye positioning information to synchronize and enhance the display experience across terminals, using eye tracking devices and data control modules to ensure consistency and 3D interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image content is displayed consistently on all terminals without adjustment, then content consistency is maintained, but viewing authenticity and interest are reduced due to positional differences among operators
Solution Approach 1:
The patent applies local quality by adjusting image parameters (zoom ratio, position, scale) according to each operator's specific viewing position and pupillary distance. Each terminal displays customized image content tailored to its operator's local characteristics, transforming the uniform display into a personalized experience that maintains both consistency and adaptability
Solution Approach 2:
The system dynamically changes image display parameters including zoom ratio, position, and scale based on detected operator characteristics such as pupillary distance and eye position. These parameter adjustments enable the same content to be presented in multiple adapted forms, resolving the contradiction between maintaining content consistency and adapting to individual viewing conditions
2Adaptability or versatility
If eye tracking devices and data control modules are added to adjust images dynamically, then viewing authenticity and interest are enhanced, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the data control module to handle multiple tasks: receiving operator information, calculating adjustment parameters, controlling image display, and coordinating with eye tracking devices. This universal module reduces overall system complexity by consolidating functions that would otherwise require separate components
Solution Approach 2:
The data control module serves as an intermediary between the eye tracking device and the image display system. It receives raw data from the eye tracking device, processes it to determine appropriate adjustments, and then controls the image display accordingly. This intermediary approach simplifies the system architecture by creating a clear separation of concerns and standardized interfaces
3Reliability
If dynamic image adjustment based on eye positioning is implemented, then content authenticity is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary action by pre-calculating and storing adjustment parameters for different operator characteristics and viewing conditions. When an operator views content, the system quickly retrieves and applies the appropriate pre-computed parameters rather than calculating them in real-time, significantly reducing processing time while maintaining content authenticity
Solution Approach 2:
The eye tracking device provides continuous feedback on operator eye position and pupillary distance, enabling the system to dynamically adjust image parameters in real-time. This feedback mechanism allows the system to maintain high content authenticity by continuously adapting to the operator's actual viewing state without requiring excessive processing time
