Correlation coefficient correction method, exercise analysis method, correlation coefficient correction apparatus, and program

A correlation coefficient correction apparatus comprising:

• a reference velocity calculation section that calculates a reference velocity by using a detection result in a first sensor, wherein the first sensor includes a positioning sensor mounted on a first portion of a moving object;
• a walking characteristic information calculation section that calculates characteristic information regarding walking of a moving object by using a detection result in a second sensor, wherein the second sensor includes an inertial sensor mounted on a second portion of the moving object;
• and
• a correlation coefficient correction section that corrects a correlation coefficient in a correlation expression indicating a correlation between the characteristic information and a walking velocity or a stride of the moving object by using the reference velocity, wherein the walking velocity or the stride of the moving object is determined using the corrected correlation coefficient.

A non-transitory computer readable storage medium storing a program, which when executed by a computer, causes the computer to perform:

• calculating a reference velocity by using a detection result in a first sensor, wherein the first sensor includes a positioning sensor mounted on a first portion of a moving object;
• calculating characteristic information regarding walking of the moving object by using a detection result in a second sensor, wherein the second sensor includes an inertial sensor mounted on a second portion of the moving object;
• and
• correcting a correlation coefficient in a correlation expression indicating a correlation between the characteristic information and a walking velocity or a stride of the moving object by using the reference velocity, wherein the walking velocity or the stride of the moving object is determined using the corrected correlation coefficient.
