Abstract
In case that users exercise for healthcare, the users require the effect of exercise. Gait speed measurement is focused as the useful index of the effect by exercise. Gait speed is correlated with Energy consumption, and one of the most basic index. The object of this study is to construct the "Wearable Information Healthcare System". As the first step of this study, the algorithm of accurate and convenient analysis method of gait speed is developed. The new algorithm is evaluated in the field test, and the calculated value is agreed to the true value.
