AI Technical Summary

Technical Problem

Existing methods for observing the vestibular ocular reflex require attaching a three-axis gyrosensor to the subject's head, which is cumbersome and requires complex calculations, making it difficult to accurately assess the driver's concentration level.

Method used

An electronic device that uses a first detection unit to detect the movement of the target based on reflected electromagnetic waves, an acquisition unit to acquire an image, a second detection unit to detect pupil movement, and a calculation unit to calculate the degree of concentration based on pupil and target movement.

Benefits of technology

Enables the calculation of the driver's concentration level in a simple and accurate manner without the need for attaching sensors to the subject, allowing for effective monitoring of driver attention.

Abstract

To calculate the degree of concentration of an object person with a simple method.SOLUTION: An electric apparatus 10 has a first detection unit 11, a second detection unit 13 and a calculation unit 14. The first detection unit 11 detects movement of an object to be detected on the basis of a reflection wave of an emitted electromagnetic wave. The second detection unit 13 detects movement of the pupil of the object to be detected included in an image. The calculation unit 14 calculates a first value indicating the degree of vestibulo-ocular reflex of the object to be detected on the basis of the movement of the pupil and the movement of the object to be detected.SELECTED DRAWING: Figure 1
