Device control device and device control method

Abstract

A device control device for controlling an on-vehicle device based on a vital sign of a user, the device control device including: a vital sign measurement unit (101) configured to measure, in time series, the vital sign of the user; a parameter extraction unit (102) configured to extract time-series parameter values for evaluating current statuses of the user based on the vital sign measured continuously by the vital sign measurement unit (101); a determination unit (120) configured to determine whether a factor of a change in the vital sign is a change in a health condition of the user or a change in an environment temperature around the user, based on the parameter values extracted by the parameter extraction unit; and a control unit (130) configured to control the on-vehicle device based on a result of the determination made by the determination unit (120).

Description

TECHNICAL FIELD[0001]The present invention relates to device control devices for controlling on-vehicle devices, and in particular to a device control device for evaluating the health condition of a person based on a change in a vital sign, and performing device control suitable for the evaluated health condition in order to make better the person's health condition.BACKGROUND ART[0002]Recently, various research groups have been studying techniques for evaluating the health conditions of people based on their vital signs. As the results, some researchers found the correlation between the health conditions of the people and their vital signs, and proposed methods for evaluating the health conditions of people based on their vital signs at academic meetings. However, such correlation analysis was performed based on changes in vital signs observed in segments where the health conditions surely changed, and thus these results are mere results obtained at laboratories far different from ...

AI Technical Summary

Benefits of technology

[0034]The present invention provides a device control device that evaluates a user's health condition based on a vital sign such as a pulse wave and controls a device, more specifically, the device control device discriminates the influence of a thermal environment and the influence of a health condition by firstly determining whether or not a change in the vital sign is made due to the influence of the thermal environment, and performs reliable device control for making better the user's health condition.

Problems solved by technology

However, such correlation analysis was performed based on changes in vital signs observed in segments where the health conditions surely changed, and thus these results are mere results obtained at laboratories far different from real environments.

At present, there is no established technique for performing back calculation to evaluate the health condition of a person in the case where a change in a vital sign is observed.

However, pulse waves are susceptible to body movements or the like, and thus there is a need to discriminate between pulse wave signs and noise.
