Embodiment Construction

[0036] When measuring biological data using a biosensor, body motion noise caused by the body motion of the measured person may be added to the detected biological signal, and the detected biological signal may change suddenly. When the detected biological signal to which such body motion noise has been added is signal-processed by an analog front-end circuit (hereinafter referred to as an AFE circuit) and input to an analog-to-digital converter (hereinafter referred to as an ADC), the detected biological signal exceeds the limit of the ADC. The input effective range (hereinafter, sometimes referred to as dynamic range (DR)), and in some cases, biometric data cannot be acquired during the occurrence of body motion. The AFE circuit performs signal processing such as amplification processing and offset control for detecting biological signals.

[0037] The inventors of the present invention have found that, after being delayed from the time when the body motion of the measured p...

Abstract

[Problem] To provide an information processing device, a biological data measurement system, an information processing method, and a program with which it is possible to improve the accuracy of acquired biological data. [Solution] An information processing device according to the present technology comprises a body motion noise prediction unit and a control unit. The body motion noise prediction unit predicts that body motion noise caused by body motion of the measured person is added to the detected biosignal detected from the measured person by the biosensor, based on a reference signal that is body motion information of the measured person detected by the reference signal sensor. The control unit controls signal processing of detecting the biological signal based on a prediction result of the body motion noise prediction unit.

Description

technical field [0001] The present technology relates to an information processing apparatus, a biological data measurement system, an information processing method, and a program for a biosensor to acquire biological data. Background technique [0002] When measuring biological data using a biosensor, an analog detected biological signal detected by a biological electrode attached to the person being measured is digitized by an analog-to-digital converter. During the measurement, body motion noise caused by the body motion of the person being measured may be added to the detected biosignal. In some cases, the detected biosignal added with this body motion noise is input into the analog-to-digital converter, beyond the input valid range of the analog-to-digital converter, and the biometric data cannot be acquired during the occurrence of the body motion. [0003] Patent Document 1 discloses a biological state detector that detects a pulse rate as biological data. This biol...
