Abstract

An information processing apparatus according to the present technology includes: a processing section that executes a process including a correction process of specifying noise included in perspiration data acquired by a perspiration sensor on a basis of sensor data acquired by a different type of sensor than the perspiration sensor, and removing the noise from the perspiration data. According to such a technology, noise estimated according to other sensor data can be removed from the perspiration data, making it possible to maintain high accuracy in a later process of estimating activity in the autonomic nerves.

First claim

1 . An information processing apparatus comprising:
a processing section that executes a process including a correction process of specifying noise included in perspiration data acquired by a perspiration sensor on a basis of sensor data acquired by a different type of sensor than the perspiration sensor, and removing the noise from the perspiration data.

2 . The information processing apparatus according to claim 1 , wherein
the processing section corrects the perspiration data using a noise model indicating a relationship between the noise and the perspiration data and/or the sensor data.

3 . The information processing apparatus according to claim 2 , wherein
the noise model is generated by machine learning using the perspiration data, the sensor data acquired at a same time as the acquisition of the perspiration data, and a result of the process.

4 . The information processing apparatus according to claim 2 , wherein
the noise model is a noise model associated with an individual corresponding to the perspiration data.

5 . The information processing apparatus according to claim 2 , wherein
the noise model is updated using feedback-related information acquired by user input with respect to a result of the process by the processing section.

6 . The information processing apparatus according to claim 1 , wherein
the process by the processing section additionally includes an extraction process of extracting mental perspiration data caused by mental perspiration from corrected perspiration data.

7 . The information processing apparatus according to claim 6 , wherein
the processing section extracts the mental perspiration data using an extraction model indicating a relationship between a parameter used in the extraction process and the corrected perspiration data and/or the sensor data.

8 . The information processing apparatus according to claim 6 , wherein
the process by the processing section additionally includes an estimation process of estimating activity in autonomic nerves of an individual corresponding to the perspiration data, on a basis of the extracted mental perspiration data.

9 . The information processing apparatus according to claim 8 , wherein
the processing section estimates the activity in the autonomic nerves on a basis of a time-series distribution of the mental perspiration data.

10 . The information processing apparatus according to claim 8 , wherein
the processing section estimates the activity in the autonomic nerves of the individual corresponding to the perspiration data by using an activity estimation model indicating a relationship between a parameter used in the estimation process and the mental perspiration data and/or the sensor data.

11 . The information processing apparatus according to claim 8 , wherein
the extraction process includes a process of additionally extracting thermal perspiration data caused by thermal perspiration from the corrected perspiration data, and the estimation process includes a process of estimating the activity in the autonomic nerves of the individual corresponding to the perspiration data by using the extracted thermal perspiration data.

12 . The information processing apparatus according to claim 8 , wherein
the activity in the autonomic nerves includes activity in sympathetic nerves.

13 . The information processing apparatus according to claim 8 , further comprising:
an output control section that controls an output according to a result of estimating the activity in the autonomic nerves.

14 . The information processing apparatus according to claim 1 , wherein
the processing section executes the process on a basis of the sensor data acquired at a same time as the acquisition of the perspiration data.

15 . The information processing apparatus according to claim 1 , further comprising:
a context acquisition section that acquires context related to an individual on whom the perspiration sensor is worn or attached, wherein the processing section executes the process by additionally using the context.

16 . The information processing apparatus according to claim 1 , wherein
the different type of sensor than the perspiration sensor includes at least one sensor worn on or attached to an individual.

17 . The information processing apparatus according to claim 16 , wherein
the sensor worn on or attached to the individual includes a biological sensor that detects biological information about the individual, and/or a tracking sensor that detects a motion of the individual.

18 . The information processing apparatus according to claim 1 , wherein
the different type of sensor than the perspiration sensor includes at least one sensor that acquires environmental information related to a predetermined space.

19 . An information processing method, executed by a processor, comprising:
acquiring perspiration data acquired by a perspiration sensor; and specifying noise included in the perspiration data on a basis of sensor data acquired by a different type of sensor than the perspiration sensor, and removing the noise from the perspiration data.

20 . A program causing a computer to function as:
a processing section that executes a process including a correction process of specifying noise included in perspiration data acquired by a perspiration sensor on a basis of sensor data acquired by a different type of sensor than the perspiration sensor, and removing the noise from the perspiration data.
