Electronic device and display system recognizing eye fatigue and looking away

An electronic device comprising:

• an arithmetic circuit;
• a display portion comprising a pixel and a pixel circuit electrically connected to the pixel;
• and
• a plurality of headphones configured to be put on a plurality of users,
• wherein each of the plurality of headphones comprise a sensor portion comprising a plurality of sensors,
• wherein the sensor portion is configured to obtain a change over time in information including at least one of a pulse, a blood pressure and a body temperature of a user putting on the headphones,
• wherein the arithmetic circuit is configured:
• to estimate a user's stress situation on the basis of the change over time in information for the determination of whether each of the plurality of users is a user with high-level stress;
• to determine whether each of the plurality of users is a user with high-level stress on the basis of the estimated user's stress situation;
• to determine whether each of the plurality of users is a user who is looking away on the basis of a change over time in information including a sight direction of the user;
• and
• to generate string information in accordance with the determination of whether each user is a user with high-level stress and the determination of whether each user is a user who is looking away,
• wherein the arithmetic circuit is configured to distinguish the user with high-level fatigue from the user who is looking away as different situations, and
• wherein the display portion is configured to display the string information.

A display system comprising a first electronic device and a second electronic device,

• wherein the first electronic device comprises a camera and an arithmetic circuit,
• wherein the second electronic device comprises a display portion,
• wherein the display portion comprises a pixel and a pixel circuit electrically connected to the pixel,
• wherein the camera is configured to obtain eye information of a user of the first electronic device by capturing an image including an eye of the user of the first electronic device,
• wherein the arithmetic circuit is configured to determine whether the user of the first electronic device is a user with high-level fatigue and to determine whether the user of the first electronic device is a user who is looking away, so that the first electronic device generates status information of the user of the first electronic device,
• wherein the determination of whether the user of the first electronic device is a user with high-level fatigue is estimated from the eye information on the basis of a change over time in information including at least one of a frequency of eye blinks, a time taken for one blink, a distance between an upper eyelid and a lower eyelid, and an area of a pupil of the user of the first electronic device,
• wherein the determination of whether the user of the first electronic device is a user with taking eyes off is estimated from the eye information on the basis of a change over time in information including a sight direction of the user of the first electronic device,
• wherein the arithmetic circuit is configured to distinguish the user with high-level fatigue from the user who is looking away as different situations, and
• wherein the display portion is configured to display the status information accepted from the first electronic device.
