Patent US10504616


Issued 2019-12-10

Display System And Display Device

An example of a display system includes a sensor, a projector, and control means. The sensor senses user information for calculating a state regarding sleep of a user. The user information is, for example, biological information such as pulse. The projector projects and displays a predetermined image. The projector, for example, projects the image upward to project and display the image on the ceiling. The control means controls the projector in accordance with a state regarding sleep, which is calculated on the basis of the user information.

6 Independent Claims

  • 1. A display system, comprising: 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.

  • 2. A display system, comprising: 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.

  • 3. A display system, comprising: 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.

  • 22. A display system, comprising: 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.

  • 23. A display system, comprising: 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 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.

  • 24. A display system, comprising: 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 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.
