VR Cognitive Assessment via Active Response Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating three-dimensional cognitive ability are subjective and lack objectivity, with existing techniques suffering from accuracy issues due to reliance on passive responses and the need for large-scale apparatuses to simulate depth changes, which can lead to inaccurate results.
Innovation Solution
A three-dimensional cognitive ability evaluation system that utilizes a virtual reality headset to simulate moving objects, incorporating an object position acquisition unit, response input unit, and three-dimensional cognitive ability determination unit to assess active responses and match them with object positions, thereby quantifying cognitive abilities objectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If passive response methods (pressing switch when target reaches predetermined position) are used, then measurement can be performed with simple apparatus, but accuracy is poor due to chance results and inability to reflect active cognitive processing
Solution Approach 1:
The patent uses a display device to present virtual moving objects that replicate the visual characteristics of real objects at various distances. By copying the visual properties (size, movement trajectory, depth cues) of real-world objects into a virtual environment, the system enables accurate measurement of three-dimensional cognitive ability without requiring complex physical apparatus to simulate depth changes.
Solution Approach 2:
The patent replaces mechanical depth simulation apparatus with a display-based virtual reality system. Instead of using physical mechanisms to change the apparent depth of targets, the system uses computational graphics and display technology to present objects at different virtual distances, thereby achieving accurate measurement with simpler apparatus.
2Reliability
If large-scale apparatus are used to simulate depth changes, then measurement can assess three-dimensional cognitive ability, but the system becomes complex and difficult to deploy
Solution Approach 1:
The patent creates virtual copies of objects at different distances using display technology. These virtual objects replicate the depth cues and visual characteristics of real objects without requiring physical manipulation of large-scale apparatus. The system presents multiple virtual objects at different virtual distances simultaneously, enabling reliable assessment of three-dimensional cognitive ability with a compact, easily deployable system.
Solution Approach 2:
The patent transitions from physical depth simulation to virtual depth representation. By using display devices to present objects at different virtual distances along the depth dimension, the system achieves reliable measurement without the complexity of large-scale mechanical apparatus. The virtual environment allows flexible manipulation of depth parameters without physical constraints.
3Measurement precision
If active response methods are used, then measurement accuracy improves by eliminating chance results, but the measurement process becomes more complex
Solution Approach 1:
The patent incorporates feedback mechanisms where the system monitors the subject's responses to virtual moving objects and adjusts the measurement process accordingly. The display device presents objects at different virtual distances, and the system records the subject's active responses (e.g., identification, tracking, or interaction). This feedback loop enables accurate measurement of three-dimensional cognitive ability while maintaining user-friendly operation through intuitive interaction with the display interface.

AI summary
There are provided a system, an apparatus, a program, and a method for enabling objective evaluation of a three-dimensional cognitive ability through quantification. A three-dimensional cognitive ability of a measurement target person is evaluated by acquiring a position of a moving object, the position enabling identification of a distance between the moving object and the measurement target person, by receiving input of an active response of the measurement target person taken in response to a three-dimensional position of the object recognized by the measurement target person, and by determining whether the position of the object that is acquired and the response that is input correctly match. The moving object may be provided in virtual reality by a virtual reality headset, and the three-dimensional cognitive ability may also be evaluated by displaying a moving image of when the object seen from a predetermined point of view is moved in virtual reality from a movement start position to a movement end position, in a direction of approaching the predetermined point of view along a predetermined movement route, and based on a response corresponding to a position of the object.
