Problems solved by technology

Therefore, there is such a problem that the number of steps cannot be counted correctly for people with special walking methods, etc.
[0004] However, if the pedometer has the structure disclosed in Patent Document 1, the pedometer (at least the load sensor unit) must be mounted on the shoe, so it is inconvenient to attach and detach.
In addition, since the sensitivity of the load sensor unit must be manually adjusted, the burden on the user becomes greater
If the pedometer has the structure disclosed in Patent Document 2, if noise is mixed into the waveform within a predetermined time, the judgment standard will be misadjusted

Embodiment Construction

[0046] First, the user switches the mode of the pedometer 1 to the learning mode by using the operation unit 4 (step S41).

[0047] Next, the user instructs the start of recording of the reference waveform using the operation unit 4 (step S42)

[0048] Then, the user walks only for a reference number of steps (for example, 5 steps) (step S43).

[0049] Next, the user instructs the end of the reference waveform recording with the operation unit 4 (step S44)

[0050] Through the above steps, a determination criterion corresponding to the walking of the user is set.

[0051] (Setting Method 1 of Judgment Criteria)

[0052] Next, a method of setting the judgment criteria of the pedometer 1 according to the present embodiment will be described in detail with reference to the drawings. Figure 5 is a reference waveform showing general walking ( Figure 4 The waveform obtained in step S43). In addition, the description will be made with 5 steps as the reference number of steps. ...

Abstract

A pedometer, which has an acceleration sensor and can make switching between a measurement mode for counting the number of steps of a user based on a waveform obtained from the acceleration sensor, and a leaning mode for learning a judgment standard being used for judging one step in the measurement mode, is provided with a means for setting a judgment standard based on a reference number of steps representing the number of steps in walking for learning, and a reference waveform obtained from the acceleration sensor during walking for learning by making the user walk for learning in the learning mode.

Description

technical field [0001] The present invention relates to pedometers. Background technique [0002] Heretofore, as far as the pedometer is concerned, a pedometer having an acceleration sensor is known. In a pedometer having an acceleration sensor, acceleration fluctuations (waveform, time-series waveform) of walking are detected by the acceleration sensor. Then, the number of steps of the user is counted (statistical) based on the waveform obtained from the acceleration sensor. Specifically, a threshold value (fixed threshold value) for determining one step (one step taken during walking) is determined in advance based on the amplitude, cycle, and the like of sample waveforms obtained from multiple people. Therefore, there is a problem that the number of steps and the like cannot be counted correctly for a person with a special walking method and the like. The so-called special way of walking, for example, refers to walking and wiping the ground. In general, walking and ru...
