CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is based on PCT filing PCT/JP2019/019140, filed May 14, 2019, which claims priority to JP 2018-106524, filed Jun. 01, 2018, the entire contents of each are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to an analysis device, an analysis method, and a recording medium.

BACKGROUND ART

When a biosignal acquired from a sensor mounted on the human body is analyzed, noise or distortion occurring in the biosignal might influence analysis results in some cases. To handle this, there is a conventionally known method of removing, from analysis results, an influence of noise and distortion occurring in a biosignal.

For example, there are known methods of manually performing preprocessing by a person skilled in biosignal processing, including application of various filters such as a frequency filter to the biosignal, extraction of waveform patterns from the biosignal and conversion of the patterns to feature amounts. In addition, there is known a method of analyzing a biosignal by using a parameter and a processing flow of an analysis technique predetermined by a person skilled in biosignal processing.

SUMMARY OF THE INVENTION

Technical Problem

However, the conventional method has a problem of having difficulty in some cases in performing analysis of biosignals with ease and high efficiency. For example, the method of manually performing the preprocessing has problems of requiring high skill in biosignal processing, requiring much time for processing, and a risk of involving arbitrary operation. In addition, a method of determining the parameters and the processing flow in advance has a problem of having difficulty in some cases in managing an environmental change that occurs during biosignal measurement, for example.

Means for Solving the Problem

In order to solve the above problem and achieve a goal, an analysis device according to the present invention includes: a memory; and processing circuitry coupled to the memory and configured to: analyze data indicating a biosignal by using a predetermined analysis technique and an updated parameter corresponding to the predetermined analysis technique every time the parameter is updated, control a display to display an analysis result obtained together with an interface capable of changing display modes in response to user's operation, and update the parameter based on change in the display modes for the interface.

Effects of Invention

According to the present invention, biosignal analysis can be performed with ease and high efficiency.
