Spatial Ability Assessment Using Virtual 3D Block Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pencil-and-paper tests for assessing spatial ability are limited in their ability to accurately measure a user's spatial skills, as they rely on two-dimensional drawings rather than three-dimensional spatial reasoning.
Innovation Solution
A system and method utilizing a virtual three-dimensional environment on a display with a processor and input device, allowing users to manipulate building blocks within a defined virtual space to recreate a projected object, providing a more accurate assessment of spatial ability by enabling translational and rotational movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pencil-and-paper test with two-dimensional drawings is used, then the test implementation is simple and requires minimal equipment, but the measurement precision of spatial ability is insufficient
Solution Approach 1:
The patent transitions from two-dimensional paper-based drawings to a three-dimensional virtual environment where users can manipulate building blocks spatially. This dimensional upgrade allows users to demonstrate true spatial reasoning skills by assembling 3D objects, directly improving measurement precision while the virtual environment maintains operational simplicity through computer-based interfaces.
2Measurement precision
If a virtual three-dimensional environment with building block manipulation is implemented, then the measurement precision of spatial ability improves, but the device complexity increases
Solution Approach 1:
The patent replaces physical manipulatives and hands-on materials with a virtual computer-based system. Users interact with building blocks through a graphical interface using mouse or touch inputs, eliminating the need for physical 3D printing materials, assembly tables, and manual scoring systems. This substitution maintains high measurement precision while reducing device complexity through software-based implementation.
3Loss of information
If projection graphics on multiple vertical planes are used, then the information completeness for spatial assessment improves, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent introduces an interactive computer interface as an intermediary between the projection graphics and the user. The system automatically generates and displays orthogonal projections on multiple vertical planes, and automatically evaluates the user's assembly against the correct solution. This intermediary eliminates the need for users to manually interpret complex multi-view projections, reducing detection difficulty while maintaining complete spatial information delivery.

AI summary
A method to be implemented by a processor includes steps of: generating an assessment interface which includes a projection graphic that depicts a projection of an expected virtual object onto a plane; controlling a display to display the assessment interface thus generated; controlling, after receiving a movement instruction or a rotation instruction, the display to refresh display of the assessment interface such that a selected one of building block(s) is moved or rotated; and controlling, when it is determined that an asserted virtual object formed by an arrangement of the building block(s) shown in the assessment interface conforms with the expected virtual object, the display to display a result of the assessment.
