ALERT INFORMATION PRESENTING APPARATUS, ALERT INFORMATION PRESENTING METHOD, AND BLOOD PRESSURE INFORMATION OUTPUTTING METHOD

摘要

An alert information presenting apparatus includes an undressing condition determiner that determines, by using a movement speed of the user, a second time period indicating a time period before undressing, and a third time period indicating a time period after undressing, a heartbeat acquirer that acquires a heartbeat timing in the second time period and a heartbeat timing in the third time period, a pulse wave acquirer that acquires a pulse wave timing in the second time period and a pulse wave timing in the third time period, a blood pressure calculator that calculates a pre-undressing blood pressure by using a pre-undressing heartbeat timing and a pre-undressing pulse wave timing, and calculates a post-undressing blood pressure by using a post-undressing heartbeat timing and a post-undressing pulse wave timing, and an information presenter that presents the user with alert information based on a difference between the pre-undressing and post-undressing blood pressures.

主权项

1. An alert information presenting apparatus comprising:
a signal acquirer that acquires a receive signal including a radio wave reflected by a user; an undressing condition determiner that determines, by using a movement speed of the user determined by using the receive signal and indicating a speed of a movement performed by the user,
a first time period indicating a period of time during which the user is undressing,a second time period immediately preceding the first time period and indicating a period of time before the user undresses, anda third time period immediately following the first time period and indicating a period of time after the user undresses; a heartbeat acquirer that acquires, by using the receive signal, a pre-undressing heartbeat timing and a post-undressing heartbeat timing, the pre-undressing heartbeat timing indicating a heartbeat timing in the second time period, the post-undressing heartbeat timing indicating a heartbeat timing in the third time period; a pulse wave acquirer that acquires a pre-undressing pulse wave timing and a post-undressing pulse wave timing, the pre-undressing pulse wave timing indicating a pulse wave timing in the second time period, the post-undressing pulse wave timing indicating a pulse wave timing in the third time period; a blood pressure calculator that calculates a pre-undressing blood pressure of the user and a post-undressing blood pressure of the user, the pre-undressing blood pressure being calculated by using a time difference between the pre-undressing heartbeat timing and the pre-undressing pulse wave timing, the post-undressing blood pressure being calculated by using a time difference between the post-undressing heartbeat timing and the post-undressing pulse wave timing; and an information presenter that presents the user with alert information based on a difference between the pre-undressing blood pressure and the post-undressing blood pressure.
