Abstract

An information processing apparatus includes a retaining unit, an image acquisition unit, an image processor, a comparator, and an image generator. The retaining unit is configured to retain a defined attachment position being an attachment position of a biological detection sensor with respect to a body site of a user, the defined attachment position being defined in advance. The image acquisition unit is configured to acquire a capture image captured by an imaging unit. The image processor is configured to extract, from the capture image, a body shape of the user. The comparator is configured to compare the body shape with the defined attachment position. The image generator is configured to generate, based on a comparison result by the comparator, a display image to be displayed on a display unit.

Claims

1. An information processing apparatus, comprising:

circuitry configured to;

acquire an image of a user with a biosignal detection sensor;

acquire information indicating an attachment state of the biosignal detection sensor; and

provide at least one of a first degree of accuracy of an attachment position of the biosignal detection sensor or a second degree of accuracy of the attachment state of the biosignal detection sensor based on the image and the information,

wherein the information indicating the attachment state includes at least one of an attachment direction of the biosignal detection sensor or a degree of contact of the biosignal detection sensor.

2. The information processing apparatus according to claim 1, wherein the circuitry is further configured to display the image with a marker located at a position on the image, wherein the position corresponds to a defined attachment position.

3. The information processing apparatus according to claim 1, wherein the circuitry is further configured to display the image with a marker located at a position on the image to generate a display image based on a defined attachment position that is different from a detected attachment position detected from the acquired image, wherein the position corresponds to the defined attachment position different from the detected attachment position.

4. The information processing apparatus according to claim 1, wherein the biosignal detection sensor includes an electroencephalographic electrode, and

wherein the circuitry is further configured to determine the attachment state based on contact resistance of the electroencephalographic electrode.

5. The information processing apparatus according to claim 1, wherein the circuitry is further configured to:

detect the attachment position of the biosignal detection sensor from the image;

compare the detected attachment position with a defined attachment position of the biosignal detection sensor; and

provide the first degree of accuracy based on the comparison.

6. An information processing method, comprising:

in an information processing apparatus;

acquiring an image of a user with a biosignal detection sensor;

acquiring information indicating an attachment state of the biosignal detection sensor; and

providing at least one of a first degree of accuracy of an attachment position of the biosignal detection sensor or a second degree of accuracy of the attachment state based on the image and the information,

wherein the information indicating the attachment state includes at least one of an attachment direction of the biosignal detection sensor or a degree of contact of the biosignal detection sensor.

7. A non-transitory computer-readable medium having stored thereon computer-readable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:

acquiring an image of a user with a biosignal detection sensor;

acquiring information indicating an attachment state of the biosignal detection sensor; and

providing at least one of a first degree of accuracy of an attachment position of the biosignal detection sensor or a second degree of accuracy of the attachment state based on the image and the information,

wherein the information indicating the attachment state includes at least one of an attachment direction of the biosignal detection sensor or a degree of contact of the biosignal detection sensor.
