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

What is claimed is:

1. An information processing apparatus, comprising:
a processing section configured to:
acquire perspiration data corresponding to an individual from a perspiration sensor and sensor data from a specific sensor different from the perspiration sensor, wherein the perspiration data includes thermal perspiration data and mental perspiration data;
remove, based on the sensor data, noise from the perspiration data to obtain corrected perspiration data;
extract the mental perspiration data from the corrected perspiration data based on an extraction model that indicates a relationship between the corrected perspiration data and a parameter associated with the extraction of the mental perspiration data, wherein the mental perspiration data corresponds to mental perspiration that is based on an activity in autonomic nerves of the individual;
extract the thermal perspiration data from the corrected perspiration data, wherein the thermal perspiration data corresponds to thermal perspiration different from the mental perspiration; and
estimate the activity in the autonomic nerves of the individual based on the extracted mental perspiration data and the extracted thermal perspiration data;
acquire feedback-related information based on a user input with respect to a result of the estimation of the activity in the autonomic nerves, wherein the user input indicates whether the result of the estimation of the activity in the autonomic nerves is correct; and
update the extraction model based on the acquired feedback-related information.

2. The information processing apparatus according to claim 1 , wherein the processing section is further configured to remove the noise from the perspiration data based on a noise model that indicates a relationship between the noise and at least one of the perspiration data or the sensor data.

3. The information processing apparatus according to claim 2 , wherein the processing section is further configured to update the noise model based on the acquired feedback-related information.

4. The information processing apparatus according to claim 1 , wherein the specific sensor acquires the sensor data at a same time as an acquisition of the perspiration data by the perspiration sensor.

5. The information processing apparatus according to claim 1 , wherein the processing section is further configured to estimate the activity in the autonomic nerves based on a time-series distribution of the mental perspiration data.

6. The information processing apparatus according to claim 1 , wherein
the processing section is further configured to estimate the activity in the autonomic nerves of the individual based on an activity estimation model, and
the activity estimation model indicates a relationship between:
a parameter associated with the estimation of the activity, and
at least one of the mental perspiration data or the sensor data.

7. The information processing apparatus according to claim 1 , wherein the activity in the autonomic nerves includes an activity in sympathetic nerves.

8. The information processing apparatus according to claim 1 , further comprising a context acquisition section configured to acquire context information related to the individual, wherein
the perspiration sensor is at least one of wearable by the individual or attachable to the individual, and
the processing section is further configured to remove the noise from the perspiration data based on the context information.

9. The information processing apparatus according to claim 1 , wherein the specific sensor different from the perspiration sensor is at least one of wearable by the individual or attachable to the individual.

10. The information processing apparatus according to claim 9 , wherein the specific sensor includes at least one of:
a biological sensor that detects biological information of the individual, or
a tracking sensor that detects a motion of the individual.

11. The information processing apparatus according to claim 1 , wherein the specific sensor different from the perspiration sensor acquires environmental information related to a space.

12. The information processing apparatus according to claim 1 , further comprising a context acquisition section configured to acquire context information related to an environment around the individual, wherein
the perspiration sensor is at least one of wearable by the individual or attachable to the individual, and
the processing section is further configured to remove the noise from the perspiration data based on the context information related to the environment around the individual.

13. An information processing method, comprising:
acquiring perspiration data corresponding to an individual from a perspiration sensor and sensor data from a specific sensor different from the perspiration sensor, wherein the perspiration data includes thermal perspiration data and mental perspiration data;
removing, based on the sensor data, noise from the perspiration data to obtain corrected perspiration data;
extracting mental perspiration data from the corrected perspiration data based on an extraction model that indicates a relationship between the corrected perspiration data and a parameter associated with the extraction of the mental perspiration data, wherein the mental perspiration data corresponds to mental perspiration that is based on an activity in autonomic nerves of the individual;
extracting the thermal perspiration data from the corrected perspiration data, wherein the thermal perspiration data corresponds to thermal perspiration different from the mental perspiration;
estimating the activity in the autonomic nerves of the individual based on the extracted mental perspiration data and the extracted thermal perspiration data;
acquiring feedback-related information based on a user input with respect to a result of the estimation of the activity in the autonomic nerves, wherein the user input indicates whether the result of the estimation of the activity in the autonomic nerves is correct; and
updating the extraction model based on the acquired feedback-related information.

14. A non-transitory computer-readable medium having stored thereon computer-executable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:
acquiring perspiration data corresponding to an individual from a perspiration sensor and sensor data from a specific sensor different from the perspiration sensor, wherein the perspiration data includes thermal perspiration data and mental perspiration data;
