Body movement detecting apparatus and body movement detecting method

There is provided a body movement detecting apparatus including: a body movement data acquiring unit configured to detect a body movement of a user and acquire body movement data relating to the body movement; a memory unit configured to memorize the body movement data corresponding to the type of an activity of the user as registered body movement data; a body movement determining unit configured to compare the body movement data acquired by the body movement data acquiring unit with the registered body movement data and determine the type of the activity of the user; and a computing unit configured to be able to calculate consumed energy by the body movement corresponding to the type of the activity determined by the body movement determining unit.

A body motion measuring apparatus is described, embodiments of which include an apparatus for detecting the magnitudes of motions in different directions at a time using body motion sensors, calculating the size V of a composite vector based on the relationship between the magnitudes of the motions, comparing the size V of the composite vector with a reference value to determine whether the size V of the composite vector is adequate, calculating an angle &#x3b8; based on the relationship between the magnitudes of the motions when V is determined to be adequate, calculating a body motion output M taking the angle &#x3b8; into account, and counting a predetermined body motion based on the relationship between M and a predetermined elapsed time.

Body motion measuring apparatus

An activity-induced energy expenditure estimating instrument is provided which is capable of estimating an activity-induced energy expenditure with ease and high accuracy. The activity-induced energy expenditure estimating instrument comprises: body activity information measuring means, body specifying information acquiring means, body composition information acquiring means, and activity-induced energy expenditure computing means, wherein the body activity information measuring means measures body activity information, the body specifying information acquiring means acquires body specifying information, the body composition information acquiring means acquires body composition information, and the activity-induced energy expenditure computing means calculates an activity-induced energy expenditure corresponding to these body activity information, body specifying information and body composition information, by use of correlation data representing correlations between the body activity information, body specifying information and body composition information and an activity-induced energy expenditure.

Activity-induced energy expenditure estimating instrument

There is provided a system capable of estimating biological data such as a pulse at the time of walking (exercise) with good reproducibility. Biological data at the time of walking is estimated indirectly by acquiring a relationship between biological data and exercise stress levels in body burden capacity acquiring means prior to walking, acquiring an exercise stress level at the time of walking in means for acquiring an exercise stress level at the time of walking, and relating the exercise stress level at the time of walking to the relationship between biological data and exercise stress levels in means for estimating biological data at the time of walking. Further, a walking amount is also computed by use of the biological data at the time of walking in walking amount computing means
