Solution Overview
Problem
There is a lack of clear references for evaluating comfortable touching, making it difficult to assess and ensure the repeatability of sympathetic touching, which is essential in various settings such as medical care, education, and emotional support.
Innovation Solution
A touching evaluation device and method that measure contact pressures and speed using sensors, comparing these values to predetermined reference ranges to determine if the touching is comfortable or uncomfortable, with specific ranges established for different body areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sympathetic touching is performed without clear reference standards, then the touching can be performed freely and naturally, but the accuracy of evaluating whether the touching causes comfort is low and repeatability cannot be ensured
Solution Approach 1:
The patent applies parameter changes by establishing specific quantitative reference ranges for contact pressure (0.001-2.000 kgf/cm² for whole body, 0.001-1.000 kgf/cm² for face) and contact speed (1-20 cm/sec). These parameter standards transform the subjective evaluation of comfortable touching into an objective measurement system, enabling accurate assessment while maintaining operational simplicity through clear numerical thresholds.
2Measurement precision
If multiple sensors are used to measure contact pressure at different positions, then the measurement precision of touching evaluation is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the measurement system into multiple independent sensors positioned at different locations (first sensor and second sensor at different positions). Each sensor independently measures contact pressure, and the system evaluates touching comfort by comparing measurements from multiple positions. This segmentation approach improves measurement comprehensiveness while maintaining modular simplicity.
Solution Approach 2:
The patent applies universality by designing sensors with multi-functional capability that simultaneously measure both contact pressure and contact speed. This allows a single sensor system to perform multiple measurement functions, improving evaluation accuracy without proportionally increasing device complexity.

AI summary
Measurement control part measures contact pressures and a contact speed of a hand of a contacting person. The contact pressures change over time at respective positions, as measured values respectively based on two sensors when the hand of the contacting person touches sequentially to the two sensors being capable of detecting contact pressure. A determination control part compares measured values with reference ranges respectively, the reference range being a predetermined for a contacted person feeling comfortable when touched by the contacting person, and determines whether or not the measured value is within the reference range for each of measured values. An evaluation control part evaluates that the touching of the contacting person is a comfortable touching when all the measured values are within corresponding reference ranges respectively, and evaluates that the touching of the contacting person is an uncomfortable touching when one measured value is outside the corresponding reference range.
