Embodiment approach 1

[0053] Below, according to Figure 1 to Figure 5 One embodiment of the present invention will be described. figure 1 It is a block diagram of the mobile terminal (body movement measurement device, mobile phone) 1 of this embodiment. Such as figure 1As shown, the portable terminal 1 includes an X-axis direction body motion sensor (acceleration detection unit) 11, a Y-axis direction body motion sensor (acceleration detection unit) 12, a Z-axis direction body motion sensor (acceleration detection unit) 13, and a control unit 10. , a communication unit 14 , a display unit 15 , an input unit 16 , and a storage unit 17 . The control unit 10 includes a quantization unit (quantization unit) 101, an offset correction unit 102, a scalarization unit (scalarization unit) 103, a moving average calculation unit (average calculation unit) 104, a peak detection unit (peak detection unit) ) 105, step counting unit (step detection unit) 106.

[0054] According to the above configuration, in...

Embodiment approach 2

[0103] Below, based on Figure 6 to Figure 9 Other embodiments of the present invention will be described. In addition, for convenience of description, components having the same functions as those described in Embodiment 1 above are given the same reference numerals, and description thereof will be omitted.

[0104] In Embodiment 1 above, the cycle interval from the point when the sign of (A-MA) changes from "negative" to "positive" to the point when it changes from "negative" to "positive" again , the step counting section 106 counts the number of steps in this interval, where (A-MA) is the difference between the acceleration A output from the scalarization section 103 and the moving average MA output from the moving average calculation section 104 .

[0105] However, in the above-mentioned 1-cycle interval, the acceleration A may change due to external factors unrelated to walking, and a local maximum / minimum value of the acceleration A may occur. Thus, the sign between ...

Embodiment approach 3

[0133] Below, based on Figure 10 to Figure 13 Another embodiment of the present invention will be described. For convenience of description, components having the same functions as those shown in Embodiments 1 and 2 above are given the same reference numerals, and description thereof will be omitted.

[0134] In the present embodiment, the number of steps can be accurately counted in consideration of the "jump" that accompanies walking. Here, "jumping" refers to a case where, although not walking, the relationship between the maximum value and the minimum value in the waveform of the acceleration A is similar to the maximum value when the number of steps should be counted. relationship with the minimum value.

[0135] In Embodiments 1 and 2 above, the step counting unit 106 regards the following conditions as the necessary conditions for adding 1 to the step count: the maximum value UP and the MA when the maximum value UP occurs UP The difference between the minimum value ...

Abstract

A mobile terminal (1) comprises an X-axis direction body motion sensor (11), a Y-axis direction body motion sensor (12) and a Z-axis direction body motion sensor (13) for detecting accelerations of a plurality of directions, a scalar-making unit (103) for synthesizing the accelerations which were detected by the X-axis direction body motion sensor (11), the Y-axis direction body motion sensor (12) and the Z-axis direction body motion sensor (13), to make the synthesized accelerations into scalars, a peak detecting unit (105) for acquiring the synthesized values, which were synthesized and made into the scalars by the scalar-making unit (103), thereby to detect the maximum value and the minimum value of the acquired synthesized values, and a step number counting unit (106) for incrementing the step number by one count when the difference between the maximum value and the minimum value detected by the peak detecting unit (105) exceeds a predetermined value. As a result, the body motion can be precisely measured without being influenced by the errors of the sensors and the errors due to the change in an offset voltage value.

Description

technical field [0001] The present invention relates to a body motion measurement device, and more particularly, to a body motion measurement device capable of accurate measurement even if an error occurs in a body motion sensor or a bias voltage, a mobile phone, a control method for a body motion measurement device, a control program for a body motion measurement device, and a body motion measurement device. A computer-readable recording medium on which the program is recorded. Background technique [0002] With the health epidemic in recent years, people have begun to have a new understanding of walking. There are many literatures suggesting that walking about 10,000 steps a day is good for your health. Therefore, in order to measure the number of steps of oneself, many people use a pedometer. The pedometer counts the number of steps of the wearer by wearing it on the human body or the like. [0003] The pedometer is used to be installed on the human body to detect the ...
