Abstract

Total consumed calories are indicated in an upper portion of a display. A life activity intensity of each of the past seven days and an average life activity intensity over the same period are indicated by a bar graph in a lower portion of the display. The life activity intensity is classified into rank I (light), rank II (medium), and rank III (a little heavy). A total exercise amount (i.e., total consumed calories) and a life activity intensity are calculated and automatically displayed at the end of a day.

Claims

1. An exercise amount measuring device comprising an acceleration sensor for detecting a body movement of a living body, means for calculating an exercise amount based on a detection signal of the acceleration sensor, a display section for displaying the calculated exercise amount,

means for calculating a life activity index based on a measured exercise amount;

and

means for causing the display means to display the calculated life activity index, wherein the life activity index is calculated according to the following formula;

0.9×

(total energy metabolism per day÷

basal metabolism).

2. The exercise amount measuring device according to claim 1, wherein the life activity index is displayed in the form of one of ranks that have been preset by classifying the life activity index so that the ranks correspond to respective life activity intensities.

3. The exercise amount measuring device according to claim 2, wherein the difference is displayed in the form of an exercise time corresponding to the difference.

4. An exercise amount measuring device comprising an acceleration sensor for detecting a body movement of a living body, means for calculating an exercise amount based on a detection signal of the acceleration sensor, a display section for displaying the calculated exercise amount,

means for classifying an action of the living body as one of a plurality of action types based on the detection signal of the acceleration sensor, calculating consumed energies of the respective action types, and calculating a total consumed energy from the calculated consumed energies;

and

means for causing the display section to display the calculated total consumed energy.

5. The exercise amount measuring device according to claim 4, wherein the action of the living body is classified by discriminating a pattern of an output waveform of the acceleration sensor.

6. The exercise amount measuring device according to claim 4, wherein the action types includes sleeping, sitting, standing, walking and running.

7. The exercise amount measuring device according to claim 4, further comprising means for causing the display section to display a ratio among time lengths of the respective action types.

8. The exercise amount measuring device according to claim 4, further comprising means for causing the display section to display a pattern of occurrence of the action types in a time order at predetermined time intervals.

9. The exercise amount measuring device according to claim 5, wherein an average of amplitudes of acceleration of one-step sections of the acceleration waveform is calculated, and the action is judged to be walking if the average is smaller than or equal to a prescribed amplitude, and to be running if the average is larger than the prescribed amplitude, wherein the action is judged to be standing if downward acceleration appears first and upward acceleration appears next in the acceleration waveform, and to be sitting if upward acceleration appears first and downward acceleration appears next in the acceleration waveform, and wherein the action is judged to be sleeping if there occurs no variation in the acceleration waveform in a prescribed period.

10. An exercise amount measuring device comprising an acceleration sensor for detecting a body movement of a living body, means for calculating an exercise amount based on a detection signal of the acceleration sensor, a display section for displaying the calculated exercise amount,

means for classifying an action of the living body as one of a plurality of action types, calculating consumed energies of the respective action types, and calculating a total consumed energy from the calculated consumed energies;

and

means for causing the display section to display the calculated total consumed energy, wherein the consumed energy of each action is calculated according to the following formula;

{(relative metabolic rate of the action)+1.2}×

(time length of the action)×

(basal metabolism).
