Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distance determination is based on estimations by multiple users, then the measurement process is simple, but the measurement precision deteriorates
Solution Approach 1:
The patent replaces the mechanical/manual estimation method with an automated optical detection system. A camera captures images of the user, and image processing algorithms automatically calculate facial feature positions and distances, substituting human estimation with machine-based measurement that provides higher precision without requiring manual intervention from multiple users.
Solution Approach 2:
The patent uses image copying and processing to determine distance. Instead of direct physical measurement or human estimation, the system captures a visual copy (image) of the user, extracts facial feature coordinates from this copy, and calculates distance based on the copied visual data. This allows precise measurement through digital image analysis rather than physical measurement tools.
2Measurement precision
If automated detection methods are used to improve precision, then measurement precision improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The system performs self-service detection by automatically capturing images, identifying facial features, calculating coordinates, and determining distances without requiring external operators. The electronic device autonomously completes the entire measurement process from image acquisition to distance calculation, reducing the need for complex external detection infrastructure while maintaining high precision.
Solution Approach 2:
The patent performs preliminary actions by pre-establishing the coordinate system, pre-identifying facial feature positions in the image, and pre-calculating reference distances before final distance determination. This preliminary processing of image data and coordinate mapping simplifies the subsequent distance calculation step while ensuring high precision through pre-computed reference values.

AI summary
The present disclosure provides an information processing method and an electronic device. The information processing method is applied in an electronic device comprising or being connected to a display unit. The method comprises: acquiring a first target object containing a first display image and a second display image different from the first display image; displaying the first display image based on a first display parameter and displaying the second display image based on a second display parameter different from the first display parameter, such that a first user using the electronic device perceives a first distance value larger than zero, the first distance value indicating a distance between a plane where a display position of the first target object is located and a plane where the display unit is located; detecting user location information corresponding to the first user; and determining a second distance value between the first user and the first target object based on the user location information. In this way, the distance between the user and the first target object as perceived by the user can be determined more accurately.
