Abstract

A biological information processing system includes a pulse wave information acquisition unit that acquires pulse wave information of a user; and a processing unit that instructs an alarm control unit to perform alarm cancellation when it is determined that the user has transitioned from a sleep state to an awakened state, on the basis of the pulse wave information.

First claim

What is claimed is:

1. A biological information processing system comprising:
a pulse wave information acquisition unit that acquires pulse wave information of a user; and
a processing unit that instructs an alarm control unit to:
set an alarm to an on state when it is determined that the user has transitioned from an awakened state to a sleep state, on the basis of pulse wave information, and after the alarm is set to the on state, to perform alarm cancellation to place the set alarm to an off state when it is determined that the user has transitioned from a sleep state to an awakened state, on the basis of the pulse wave information, and the awakened state has been continued for a predetermined period of time, wherein the predetermined period of time is at least twenty minutes.

2. The biological information processing system according to claim 1 , wherein the processing unit instructs the alarm control unit to set the alarm to the on state when it is determined that the user has transitioned from the awakened state to the sleep state and that the sleep state has been continued for a predetermined period of time, on the basis of the pulse wave information.

3. The biological information processing system according to claim 1 , wherein after the alarm cancellation is performed the processing unit does not give an instruction for setting of an alarm to an on state if it is determined that the user has transitioned from the awakened state to the sleep state.

4. The biological information processing system according to claim 1 , wherein if it is determined that the user has transitioned from the awakened state to the sleep state after the alarm cancellation is performed, the processing unit gives an instruction for setting the alarm to the on state.

5. The biological information processing system according to claim 1 , wherein the processing unit determines an autonomic nerve activity state on the basis of the pulse wave information, and determines the sleep state and the awakened state on the basis of the autonomic nerve activity state.

6. The biological information processing system according to claim 1 , wherein the processing unit determines an autonomic nerve activity state and a biological activity state on the basis of the pulse wave information, and determines the sleep state and the awakened state on the basis of the autonomic nerve activity state and the biological activity state.

7. The biological information processing system according to claim 1 , further comprising a body motion information acquisition unit that acquires body motion information of the user,
wherein the processing unit determines the sleep state and the awakened state on the basis of the pulse wave information and the body motion information.

8. The biological information processing system according to claim 1 , further comprising the alarm control unit.

9. The biological information processing system according to claim 1 , wherein setting the predetermined period of time is based on history of sleep of the user.

10. A biological information processing system comprising:
a processing unit that acquires pulse wave information of a user and performs setting of an alarm to an on state when it is determined that the user has transitioned from an awakened state to a sleep state on the basis of the pulse wave information, and after the alarm is set to the on state, performs alarm cancellation to place the set alarm to an off state when it is determined that the user has transitioned from a sleep state to an awakened state on the basis of the pulse wave information, and that the awakened state has been continued for a predetermined period of time, on the basis of the pulse wave information, wherein the predetermined period of time is at least twenty minutes.

11. The biological information processing system according to claim 10 , wherein when it is determined that the user has transitioned from the awakened state to the sleep state and that the sleep state has been continued for a predetermined period of time, on the basis of the pulse wave information, the alarm is set to the on state.

12. The biological information processing system according to claim 10 , wherein an alarm is not set to an on state if it is determined that the user has transitioned from the awakened state to the sleep state after the alarm cancellation is performed.

13. The biological information processing system according to claim 10 , wherein if it is determined that the user has transitioned from the awakened state to the sleep state after the alarm cancellation is performed, the alarm is set to the on state.

14. The biological information processing system according to claim 10 , wherein an autonomic nerve activity state is determined on the basis of the pulse wave information, and the sleep state and the awakened state are determined on the basis of the autonomic nerve activity state.

15. The biological information processing system according to claim 10 , wherein an autonomic nerve activity state and a biological activity state are determined on the basis of the pulse wave information, and the sleep state and the awakened state are determined on the basis of the autonomic nerve activity state and the biological activity state.

16. The biological information processing system according to claim 10 , wherein body motion information of the user is acquired, and the sleep state and the awakened state are determined on the basis of the pulse wave information and the body motion information.

17. The biological information processing system according to claim 10 , wherein setting the predetermined period of time is based on history of sleep of the user.

18. A method of controlling a biological information processing system, the method comprising:
performing a process of acquiring pulse wave information of a user;
performing setting of an alarm to an on state when it is determined that the user has transitioned from an awakened state to a sleep state on the basis of the pulse wave information; and
performing alarm cancellation to place the set alarm to an off state when it is determined that the user has transitioned from a sleep state to an awakened state, on the basis of the pulse wave information, and the awakened state has been continued for a predetermined period of time, wherein the predetermined period of time is at least twenty minutes.

19. The method of controlling a biological information processing system according to claim 18 , wherein setting the predetermined period of time is based on history of sleep of the user.
