Abstract
Official abstract text for this publication.
A step count measuring apparatus that measures the step count based on a degree of acceleration is provided. The step count measuring apparatus includes a local maximum/minimum value detection unit configured to detect at least one of a local maximum value and a local minimum value of the acceleration during a predetermined time, a threshold value determination unit configured to determine a threshold value based on at least one of the local maximum value and the local minimum value detected by the local maximum/minimum value detection unit, and a step count measuring unit configured to measure the step count based on the acceleration and the threshold value that has been determined by the threshold value determination unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A step count measuring apparatus that measures a step count based on a degree of acceleration data, the step count measuring apparatus comprising: an acceleration sensor that measures the acceleration data; and a processor, wherein the processor detects at least one of a local maximum value and a local minimum value of the acceleration data in a predetermined time, determines a threshold value based on the at least one of the local maximum value and the local minimum value that has been detected by the processor, measures the step count based on the acceleration data and the threshold value that has been determined by the processor, and wherein the processor determines a first threshold value as the threshold value in the case where the at least one of the local maximum value and the local minimum value exceeds a predetermined value, and determines, as the threshold value, a second threshold value that is less than the first threshold value in the case where the at least one of the local maximum value and the local minimum value is equal to or less than the predetermined value. 2. The step count measuring apparatus according to claim 1 , wherein the processor determines the threshold value after the local maximum value and the local minimum value have been both detected by the processor. 3. The step count measuring apparatus according to claim 1 , wherein the processor determines the threshold value after one of the local maximum value and the local minimum value has been detected by the processor. 4. The step count measuring apparatus according to claim 1 , wherein the processor measures the step count based on a difference between the local maximum value and the local minimum value that has been detected by processor. 5. The step count measuring apparatus according to claim 1 , wherein the acceleration data that is input to the processor is a sum of the squares of acceleration values in three axes including a X axis, a Y axis, and a Z axis that are orthogonal to each other. 6. A non-transitory computer readable recording medium that includes a step count measuring program used for measuring a step count based on a degree of acceleration data, the step count measuring program causes a computer to: measure the acceleration data: detect at least one of a local maximum value and a local minimum value of the acceleration data in a predetermined time; determine a threshold value based on the at least one of the local maximum value and the local minimum value that has been detected by the detecting; measure the step count based on the acceleration data and the threshold value that has been determined by the determining; determine a first threshold value as the threshold value in the case where the at least one of the local maximum value and the local minimum value exceeds a predetermined value; and determine, as the threshold value, a second threshold value that is less than the first threshold value in the case where the at least one of the local maximum value and the local minimum value is equal to or less than the predetermined value.
