Provided is a technique in which walking-related information provided by a pedometer, such as walking speed, walking distance, exercise intensity, and consumed calories have accuracy or practical accuracy and are provided through a simple configuration and at a low cost. A change in the ratio between the stride for walking pitch and height is captured by a piecewise linear function. The relationship between the walking speed and the exercise intensity is expressed as a piecewise linear function based on a known value. The arithmetical expression of the walking speed and the exercise intensity derived therefrom is subject to regression analysis, and the obtained regression line is simplified. The technique is thereby basically constituted. An error caused by the simplification is changed by the number of divided sections or the like. In the present invention, a plurality of directly usable techniques are provided so that a calculation method corresponding to a requested tolerance can be selected. Also, in order to raise the accuracy, a technique reflecting the walking characteristics of a pedometer user is provided. By combining these techniques, an ideal pedometer that is inexpensive and accurate can be created. |
