Abstract
A reduced attention state estimation system includes an eyeball movement and eyelid activity measurement unit that measures an eyeball movement and an eyelid activity of a subject to obtain eyeball movement and eyelid activity data, a section determination unit that determines an eye opening section, an eye closing section, an eye-blinking section and a cluster section based on the eyeball movement and eyelid activity data, an eyeball movement and eyelid activity-related information calculation unit that calculates a sharpness of microsaccade or the like for each eye opening section based on the eyeball movement and eyelid activity data, and an attention assessment unit that determines an attention assessment or the like for an eye opening/cluster section, which is an eye opening section and cluster section, based on the sharpness of microsaccade or the like.
