3D Display Depth Perception Distortion Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display devices distort the perception of depth and shape of objects based on observation distance and environment, failing to provide a realistic 3D experience similar to natural settings.
Innovation Solution
A measuring apparatus and method that adjusts 3D pattern parameters and uses a 3D display unit, input unit, rail, moving body, and distance sensor to objectively quantify and measure perceptual distortion, allowing for a realistic 3D image perception akin to natural environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a 3D display device displays a 3D object, then the user can perceive depth and shape, but the perceived depth and shape are systematically distorted according to observation distance, observation point, and observation environment
Solution Approach 1:
The system measures the user's actual observation distance and observation point, then feeds back this information to adjust the 3D object parameters in real-time, creating a closed-loop control system that compensates for perceptual distortion
Solution Approach 2:
The system dynamically changes the parameters of the 3D object (such as depth values, shape characteristics) based on the measured observation conditions, transforming the 3D object to compensate for the systematic distortion caused by different viewing conditions
2Measurement precision
If 3D object parameters are adjusted to compensate for perception distortion, then realistic 3D perception is achieved, but the system complexity increases due to measurement and control components
Solution Approach 1:
The system introduces a measuring apparatus as an intermediary that objectively quantifies perceptual distortion, separating the measurement function from the display function and enabling precise control without directly modifying the display device complexity
Solution Approach 2:
The system replaces subjective human judgment of depth perception with objective mechanical/electronic measurement devices (distance sensors, position sensors), substituting human perception with measurable physical quantities that can be precisely controlled

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively measures and minimizes depth and shape perception distortions, enabling a more realistic 3D experience by adjusting 3D object parameters and user input signals to align with natural depth perception standards.

AI summary
An apparatus for measuring a depth of a three-dimensional (3D) object includes a control unit generating the 3D object by adjusting parameters of a 3D pattern. A 3D display unit displays the 3D object with a preset depth. An input unit generates an input signal based on an input received from a user. A rail extends in a front and a rear of the 3D display unit. A moving body is movable on the rail. Movement of the moving body is adjusted based on the input signal. A distance sensor measures a distance to the moving body.
