Embodiment Construction

[0011] (one) Construct the relationship model between physical stimulus and sensory quantity

[0012] The Weber-Fechner Law (Weber-Fechner Law, W-F Law) is a study of the relationship between the physical characteristics of stimuli and sensory experience, which was proved and derived by Fechner in 1850 on the basis of Weber's research through psychophysical experiments. law. The theorem can determine the various sensory thresholds and measure the relationship between physical quantities and psychological feelings of stimuli under moderate-intensity stimuli. The experiment proves the functional relationship between the human body's reaction quantity k and the external environment stimulus quantity C:

[0013] k=algc, a is Weber's constant (1)

[0014] The evaluation of the tactile comfort sensation is based on the following assumptions:

[0015] A: The external environmental stimulus c is regarded as the energy value E absorbed by the human body s ;

[0016] B: Thi...

Abstract

Provided is a touch comfort level model based on the Weber-Fechner law. A relation model between physical stimulation and sensation quantity is constructed according to the Weber-Fechner law first; a functional relation between the sensation quantity and the comfort level is then put forward as a matter of experience; ultimately, fitting is carried out on model parameters through experimental data to obtain the touch comfort level model. The touch comfort level model can be used for optimal control of a rubbing process of a bath care robot and can also be used for a control system of related intelligent man-machine engineering equipment.

Description

technical field [0001] The invention relates to the field of ergonomics, in particular to a tactile somatosensory comfort model based on Weber Fechner's law. Background technique [0002] Comfort refers to the comprehensive evaluation of people's physical and psychological satisfaction with the objective environment. Affected by various factors and environmental conditions, comfort will show different results due to individual differences. At present, most studies on comfort are focused on the influence of climate on human comfort and the influence of road vehicles on human comfort. However, tactile somatosensory comfort is a very important indicator in health care, elderly and disabled devices, and there are few reports on tactile comfort at home and abroad. Inspired by psychophysics research, the present invention constructs a tactile comfort model based on energy function. Contents of the invention [0003] In order to solve the above technical problems, a tactile so...
