in a case where the user sets an alarm time as an alarm, the light-shielding and transmitting information generation unit generates light-shielding and transmitting information for controlling the transmitting state or the light-shielding state of the position of each of the plurality of regions on a basis of the orientation of the user's face in sleep on a basis of the biological information so that the user's eyes located at the specific position of the interior are irradiated with light of which a light source is the sun, which is light from the light source that exists in the exterior, at the alarm time.

4. The light-shielding device according to claim 3, (2) (5)

wherein the biological information further includes information for obtaining a sleep state of the user,

the light-shielding device further comprises,

a solar light incident angle calculation unit that calculates an incident angle of light, which is incident to each of the regions of the light-shielding wall and of which a light source is the sun, as a solar light incident angle on a basis of information of latitude and longitude as a position of the solar light incident angle calculation unit, an orientation of the light-shielding wall, and time information, and

a degree-of-sleep-depth calculation unit that determines whether or not the user is sleeping at time near the alarm time on a basis of biological information that indicates whether or not the user is sleeping in the interior and is used to obtain a sleep state of the user, and further obtains an easily waking-up time at which a depth of sleep is shallow in a case where it is determined that the user is sleeping, and

the light-shielding and transmitting information generation unit generates light-shielding and transmitting information for controlling the transmitting state or the light-shielding state of a position of each of the plurality of regions on a basis of biological information that is information indicating the orientation of the user's face in sleep, and the solar light incident angle information so that the user's eyes are irradiated with light of which a light source is the sun at easily waking-up time which corresponds to the alarm time and at which the depth of sleep is shallow.

5. The light-shielding device according to claim 4, (1) (1)

wherein the biological information for obtaining the sleep state of the user includes information of a pulse rate, a body temperature, a blood pressure, a breathing frequency, and a body turning frequency of the user.

11. The light-shielding device according to claim 4, further comprising: (0) (1)

7. The light-shielding device according to claim 1, further comprising: (3) (3)

an external information acquisition unit that acquires external information; and

a waking-up detection unit that detects waking-up of the user after the alarm time on a basis of biological information for obtaining a sleep state of the user, and

in a case where waking-up is detected after the alarm time by the waking-up detection unit, the light-shielding and transmitting information generation unit generates light-shielding and transmitting information for controlling the transmitting state or the light-shielding state of a position of each of the plurality of regions so that the user is capable of visually recognizing display based on the external information.

8. The light-shielding device according to claim 7, (0) (2)

9. The light-shielding device according to claim 7, (0) (1)

10. The light-shielding device according to claim 7, further comprising: (0) (2)

12. The light-shielding device according to claim 1, further comprising: (2) (2)

a biological information acquisition unit that acquires biological information indicating initiation of a predetermined activity of the user,

wherein the light-shielding and transmitting information generation unit generates light-shielding and transmitting information for controlling the transmitting state or the light-shielding state of a position of each of the plurality of regions so that the user is capable of visually recognizing an elapsed time from timing at which the predetermined activity of the user, which is acquired by the biological information acquisition unit, is initiated.

13. The light-shielding device according to claim 12, (0) (2)

14. The light-shielding device according to claim 12, further comprising: (0) (3)

an image capturing unit that captures an image of a user; and

a charging stand of an electric toothbrush that is used in brushing of teeth of the user,

wherein the biological information acquisition unit determines whether or not the user grips the toothbrush in an image that is captured by the image capturing unit, determines whether or not the electric toothbrush is connected to the charging stand and is capable of being charged, and acquires biological information indicating initiation of the brushing of teeth in at least one of a case where the electric toothbrush is gripped by the user, and a case where the electric toothbrush is not connected to the charging stand and is not capable of being charged in the image on a basis of the determination result.
