Abstract

A biological information measuring apparatus with a pillow shape having a convex portion to be contacted with a cervical region of a user, the apparatus includes a first measuring unit arranged on the convex portion measuring biological information about the user in a sleeping condition; a second measuring unit arranged in a position other than the convex portion measuring biological information about the user in the sleeping condition; a selecting unit selecting any one of the first and the second measuring unit based on the measured results of the first and second measuring unit; and a heart beat detecting unit detecting heart beats of the user based on the measured result of the first or the second measuring unit selected by the selecting unit.

Claims

1. A biological information measuring apparatus with a pillow shape having a convex portion to be contacted with a cervical region of a user, comprising:

a first measuring unit arranged on the convex portion measuring biological information about the user in a sleeping condition;

a second measuring unit arranged in a position other than the convex portion measuring biological information about the user in the sleeping condition;

a selecting unit selecting any one of the first measuring unit and the second measuring unit based on the measured result of the first measuring unit and the measured result of the second measuring unit; and

a heart beat detecting unit detecting heart beats of the user based on the measured result of the first measuring unit or the second measuring unit selected by the selecting unit.

2. The apparatus according to claim 1, wherein the second measuring unit is arranged in a position to be contacted with the occipital region of a user'"'"'s head.

3. The apparatus according to claim 1, wherein the second measuring unit is arranged in a position to be contacted with user'"'"'s shoulders.

4. The apparatus according to claim 1, wherein the second measuring unit is provided on a same surface where the convex portion is formed.

5. The apparatus according to claim 1, wherein the second measuring unit is provided on a surface opposite to the surface where the convex portion is formed.

6. The apparatus according to claim 1 further comprising:

a pad portion to be contacted with a user'"'"'s blade bone formed integrally with a pillow main body having the convex portion,

wherein the second measuring unit is provided to the pad portion.

7. The apparatus according to claim 1 further comprising:

a posture determining unit determining a posture of the user based on the measured result of the first measuring unit and the measured result of the second measuring unit; and

a sleeping condition determining unit determining a sleeping condition of the user based on the detected result of the heart beat detecting unit and the posture determination result of the posture determining unit.

8. The apparatus according to claim 1 further comprising:

a measuring accuracy detecting unit detecting measuring accuracy in any one of the first measuring unit and the second measuring unit selected by the selecting unit,

wherein the selecting unit selects any one of the first measuring unit and the second measuring unit when the measuring accuracy detected by the measuring accuracy detecting unit becomes smaller than a predetermined threshold.

9. The apparatus according to claim 1 further comprising:

a measuring accuracy detecting unit detecting measuring accuracy in the first measuring unit and measuring accuracy in the second measuring unit,

wherein the selecting unit selects the measuring unit with higher measuring accuracy detected by the measuring accuracy detecting unit from the first measuring unit and the second measuring unit.

10. A method of measuring biological information by using a biological information measuring apparatus with a pillow shape having a convex portion to be contacted with a cervical region of a user, comprising:

measuring biological information about the user in a sleeping condition by a first measuring unit arranged on the convex portion;

measuring biological information about the user in the sleeping condition by a second measuring unit arranged in a position other than the convex portion;

selecting any one of the first measuring unit and the second measuring unit based on the measured result of the first measuring unit and the measured result of the second measuring unit; and

detecting heart beats of the user based on the measured result of the selected any one of the first measuring unit and the second measuring unit.
