Abstract

A variation measurement device for a physical activity includes a display element that displays a variation amount of a weight data from a benchmark of the weight data, which varies depending on the physical activity of the measurement subject.

First claim

What is claimed is:

1. A variation measurement device for a physical activity, comprising:
a weight measurement element that acquires weight data for each of a plurality of measurement times during a single weighing session;
a weight data memory element that stores in a weight data memory said weight data acquired by the weight measurement element over time;
a control element that calculates a variation amount, which is a difference between a benchmark weight data that is said weight data at one of the plurality of measurement times and other weight data;
a display element that displays said variation amount over time that varies depending on a predetermined physical activity;
wherein the display element is configured to display an approximate curve or an approximate straight line fitted the variation amount from the benchmark weight to the approximate straight line or the approximate curve by regression analysis;
wherein the display element is configured to display a plurality of curves comprising the approximate curve obtained on a plurality of days of the same subject, or a plurality of straight line comprising the approximate straight line obtained on a plurality of days of the same subject, or a plurality of curves comprising the approximate curve obtained on a plurality of different subjects, or a plurality of straight lines comprising the approximate straight line obtained on a plurality of different subjects, and
the plurality of straight lines and the plurality of curves have the same height of a starting point to indicate the benchmark weight data.

2. The variation measurement device for physical activity, according to claim 1 , wherein:
said display element displays said variation amount based on a decreasing amount of a measured weight between the beginning and the end of said predetermined physical activity.

3. The variation measurement device for physical activity, according to claim 1 , wherein:
said control element fits said variation amounts from said benchmark to at least one of an approximate straight line and an approximate curve by a regression analysis, and displays a graph denoting a time-course variation of a plurality of said weight data based on at least one of said approximate straight line and said approximate curve that are acquired by said display element.

4. The variation measurement device for physical activity, according to claim 3 , wherein:
said control element estimates a time period in which said variation amount of said weight data attains an expected variation amount based on at least one of said approximate straight line and said approximate curve acquired by said fitting, and displays said time period on said display element.

5. The variation measurement device for a physical activity, according to claim 3 , wherein:
said control element displays said variation amount of said weight data, that is converted to per a unit time, on said display element based on at least one of said approximate straight line and said approximate curve acquired by said fitting.

6. A display method of a variation for a physical activity, comprising:
a step of measuring a weight of a measurement subject multiple times during a single weighing session between a beginning of a predetermined physical activity of a measurement subject and an end of said predetermined physical activity;
a step of storing weight data of each of said weight that is measured multiple times in association with each measurement time;
a step of acquiring variation amount of said weight data, that is a difference between benchmark weight data that is specified among said weight data that are stored and said weight data other than said benchmark weight data;
a step of displaying said variation amounts that vary depending on said predetermined physical activity, wherein said variation amount is acquired based on said benchmark weight of said weight data of said measurement subject;
wherein the step of displaying said variation amounts that vary depending on said predetermined physical activity includes a step of displaying an approximate curve or an approximate straight line fitted the variation amount from the benchmark weight to the approximate straight line or the approximate curve by regression analysis;
wherein the step of displaying said variation amounts that vary depending on said predetermined physical activity includes a step of displaying a plurality of curves consisting of the approximate curve obtained on a plurality of days of the same subject, or a plurality of straight line consisting of the approximate straight line obtained on a plurality of days of the same subject, or a plurality of curves consisting of the approximate curve obtained on a plurality of different subjects, or a plurality of straight lines consisting of the approximate straight line obtained on a plurality of different subjects; and
the plurality of straight lines and the plurality of curves have a same height of starting point to indicate the benchmark weight data.

7. The display method of said variation for said physical activity, according to claim 6 , wherein:
the step of displaying said variation amount of the weight based on a decrease amount of a measured weight between the beginning and the end of the physical activity.

8. The variation measurement device for a physical activity, according to claim 1 , wherein:
the display element is configured to display a rate of change in weight fluctuation obtained from the approximate straight line or the approximate curve.

9. The variation measurement device for a physical activity, according to claim 1 , wherein:
wherein the display element that displays said variation amount per hour or per minute that varies depending on a predetermined physical activity.

10. The variation measurement device for a physical activity, according to claim 1 , wherein:
the control element that calculates a variation amount with a predetermined value of less than 100 g as the unit, which is a difference between a benchmark weight data that is said weight data at one of the plurality of measurement times and other weight data; and
the display element that displays said variation amount with a predetermined value of less than 100 g as the unit over time that varies depending on the predetermined physical activity; and
wherein the display element is configured to display an approximate curve or an approximate straight line fitted the variation amount with a predetermined value of less than 100 g as the unit from the benchmark weight to the approximate straight line or the approximate curve by regression analysis, and display a rate of change in weight fluctuation obtained from the approximate straight line or the approximate curve.
