Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of standardized, objective, and quantitative methods to evaluate the impact of surrounding environments on human thinking states, particularly in distinguishing between convergent and divergent thinking.
Innovation Solution
An information processing method that uses a sensor to acquire cerebral blood flow information from a user's forehead, specifically in central and end portions, and processes this information to determine whether the user's level of divergent or convergent thinking is rising.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional cerebral blood flow measurement techniques are used to estimate concentration levels, then concentration evaluation is possible, but objective evaluation of creative thinking states (divergent and convergent thinking) cannot be achieved
Solution Approach 1:
The patent segments the forehead measurement region into multiple specific locations (central portion, end portion, and other regions) to detect different cerebral blood flow patterns. By measuring blood flow changes at distinct anatomical locations, the system can differentiate between divergent and convergent thinking states, thereby achieving both measurement precision and adaptability for various thinking state evaluations.
2Adaptability or versatility
If a single cerebral blood flow measurement point is used, then measurement simplicity is maintained, but the ability to distinguish between different thinking states is insufficient
Solution Approach 1:
The measurement system is divided into multiple detection points across the forehead region. Each point captures blood flow characteristics associated with different cognitive processes, enabling the differentiation of thinking states without requiring complex additional equipment.
Solution Approach 2:
The patent introduces spatial distribution as an additional dimension for measurement by placing sensors at multiple forehead locations. This multi-dimensional approach allows the system to capture nuanced blood flow patterns that correspond to different thinking states, enhancing discrimination capability while maintaining measurement simplicity through non-invasive optical sensors.

AI summary
An information processing method includes acquiring first cerebral blood flow information corresponding to a temporal change of cerebral blood flow in a central portion of a user's forehead in a left-right direction by using a sensor; acquiring second cerebral blood flow information corresponding to a temporal change of cerebral blood flow in an end portion of the user's forehead in the left-right direction by using the sensor; and determining by a processor whether a user's level of divergent thinking is rising or a user's level of convergent thinking is rising on the basis of comparison between the first cerebral blood flow information and the second cerebral blood flow information.
