Abstract: In a measurement computation device arranged in a measurement device, an elapse of a predetermined time is detected after acceleration of perspiration, and a concentration of a first component in the perspiration obtained thereafter is converted to concentration of the first component in blood.

Abstract: A measurement computation device arranged in a measurement device detects a first component and a second component from perspiration in a first component detection unit and a second component detection unit, and the respective concentration in the perspiration is calculated in a concentration calculation unit. In a conversion computation unit, the concentration of the first component in the perspiration is corrected using the concentration of the second component, and then converted to the concentration of the first component in the blood.

Abstract: A breathing exerciser includes: a display unit for displaying information for guiding an exercise pattern of breathing to a user; and a state switch which is capable of detecting an operation by the user and which is for accepting an operation according to a breathing state. By this, the breathing exerciser distinguishes during an exercise period during which the exercise pattern is guided, whether it is an exhalation state or an inhalation state, based on a signal from the state switch.

Abstract: A breathing exerciser includes: a guide unit for guiding an exercise pattern of breathing to a user; a biological information detecting unit for detecting biological information on the user; a biological information detection control unit for controlling detection of the biological information at timing associated with an exercise period during which the exercise pattern is guided; a characteristic value calculating unit for calculating a characteristic value that reflects an exercise index, based on the biological information detected according to the control of the biological information detection control unit, the exercise index being a target of breathing exercise; an effect index calculating unit for calculating an effect index based on at least two characteristic values, the effect index representing an effect of the breathing exercise; and an informing unit for informing the effect index to the user.

Abstract: A breathing exerciser includes: a guide unit for guiding an exercise pattern of breathing to a user; a breathing sensor for detecting breathing of the user; a breathing index calculating unit for calculating, based on a signal from the breathing sensor, a breathing index at least one of before and after an exercise period during which the exercise pattern is guided, the breathing index representing a characteristic of a breathing state of the user; and an outcome index calculating unit for calculating an outcome index based on at least two breathing indices, the outcome index representing an outcome of breathing exercise; and an informing unit for informing the outcome index to the user.
