    • The acceleration information detecting unit (11) of an acceleration detecting apparatus (10) have an acceleration sensor with at least one-axis measures the acceleration in the back and forth direction (or the right and left direction) of a walking person and sends the acceleration data indicating this acceleration to the wireless communication control unit (12). The wireless communication control unit (12) sends the acceleration data that is measured in the acceleration information detecting unit (11) to the physical movement analyzer (20) using a short-distance wireless communication method. On the other hand, the wireless communication control unit (21) of the physical movement analyzer (20) receives the acceleration data that is sent from the acceleration detecting apparatus (10) using a short-distance wireless communication method and sends it to the walking speed detecting unit (22). The walking speed detecting unit (22) estimates the strides and a walking period based on the received acceleration data and calculates the walking speed based on the strides and the walking period.
    • 加速度检测设备(10)的加速度信息检测单元(11)具有至少一个轴的加速度传感器测量步行者的前后方向(或左右方向)上的加速度, 指示该加速度的加速度数据给无线通信控制单元(12)。 无线通信控制单元(12)使用短距离无线通信方法将在加速度信息检测单元(11)中测量的加速度数据发送到物理运动分析器(20)。 另一方面,物理运动分析器(20)的无线通信控制单元(21)接收使用短距离无线通信方法从加速度检测设备(10)发送的加速度数据,并将其发送到步行 速度检测单元(22)。 步行速度检测部(22)基于接收到的加速度数据来估计步幅和步行周期,并基于步幅和步行周期来计算步行速度。
