Patent US10504616

a sensor configured to sense user information for calculating a sleep state of a user;

a projector; and

control circuitry configured to cause the projector to project and display an image related to the sleep state calculated on the basis of the user information, wherein

if the system judges, based on at least biological information calculated from the sensed user information, that the user is in a sleep state prior to awakening, the control circuitry causes the projector to automatically project and display an image for inducing awakening of the user when the system judges that the user is in the sleep state prior to awakening, and

if the system judges, based on at least the calculated biological information, that the user is in a state of awakening, the control circuitry switches the image displayed by the projector so as to automatically project and display an evaluation result of sleep for the user when the system judges that the user is in the state of awakening.

a sensor configured to sense user information for calculating a sleep state of a user;

a projector;

processing circuitry configured to specify a timing regarding awakening of the user on the basis of the user information; and

control circuitry configured to cause the projector to start projection and display of the image in accordance with the specified timing, wherein

if the system judges, based on at least biological information calculated from the sensed user information, that the user is in a sleep state prior to awakening, the control circuitry causes the projector to automatically project and display an image for inducing awakening of the user when the system judges that the user is in the sleep state prior to awakening, and

 

if the system judges, based on at least the calculated biological information, that the user is in a state of awakening, the control circuitry switches the image displayed by the projector so as to automatically project and display an evaluation result of sleep for the user when the system judges that the user is in the state of awakening.

a sensor configured to sense user information for calculating a sleep state of a user in bed;

a projector configured to project and display a predetermined image when the user is in bed;

control circuitry configured to control the projector; and

communication circuitry configured to perform communication with a server through a network, wherein

if the system judges, based on at least biological information calculated from the sensed user information, that the user is in a sleep state prior to awakening, the control circuitry causes the projector to automatically project and display an image for inducing awakening of the user when the system judges that the user is in the sleep state prior to awakening, and

if the system judges, based on at least the calculated biological information, that the user is in a state of awakening, the control circuitry switches the image displayed by the projector so as to automatically project and display an evaluation result of sleep for the user when the system judges that the user is in the state of awakening.

a sensor configured to sense user information for calculating a sleep state of a user;

a projector; and

control circuitry configured to cause the projector to project and display an image related to the sleep state calculated on the basis of the user information, wherein

if the system judges that the user experiences an awakening in mid-course of sleep at a first timing, the control circuitry causes the projector to automatically select a first image to project and display when the system judges that the user experiences the awakening in mid-course of sleep at the first timing, and

if the system judges that the user experiences an awakening that is not in mid-course of sleep at a second timing, the control circuitry causes the projector to automatically alternatively select a second image to project and display when the system judges that the user experiences the awakening that is not in mid-course of sleep at the second timing.
