Abstract

According to one aspect of the invention, there is provided a mobile apparatus including: a vibration sensor; an acquisition module configured to periodically acquire the number of vibration in a time period as a detected step count value; a first determination module configured to determine whether there is a possibility that the detected step count value is due to walking or running based on the detected step count value; and a calculation module configured to count the detected step count value as an interim step count. The first determination module determines the detected step count value is due to continuous walking or running of a user when the detected step count value satisfies a certain condition. The calculation module calculates total of the interim step count when the first determination module determines the detected step count value is due to the continuous walking or running.

Claims

1. A mobile apparatus comprising:

a vibration sensor;

an acquisition module configured to periodically acquire the number of vibration in the vibration sensor in a time period as a detected step count value;

a first determination module configured to determine whether there is a possibility that the detected step count value is due to walking or running based on the detected step count value; and

a calculation module configured to count the detected step count value as an interim step count;

wherein the first determination module determines that the detected step count value is due to continuous walking or running of a user when the detected step count value satisfies a certain condition; and

wherein the calculation module calculates total of the interim step count when the first determination module determines that the detected step count value is due to the continuous walking or running.

2. The mobile apparatus of claim 1, wherein the first determination module is configured to determine the detected step count value and a subsequent detected step count value to be due to the continuous walking or running, when a difference therebetween is within a threshold range for threshold times in series.

3. The mobile apparatus of claim 1, wherein the first determination module is configured to determine that there is the possibility when a difference between the detected step count value and a subsequent detected step count value is within a threshold range.

4. The mobile apparatus of claim 2, further comprising a second determination module configured to determine whether the mobile apparatus is in a sleep state or not, wherein the first determination module is configured to determine the threshold times based on a determination by the second determination module.

5. The mobile apparatus of claim 3, further comprising a second determination module configured to determine whether the mobile apparatus is in a sleep state or not, wherein the first determination module is configured to determine the threshold times based on a determination by the second determination module.

6. The mobile apparatus of claim 2, further comprising a second determination module configured to determine whether the mobile apparatus is in a sleep state or not, wherein the first determination module is configured to determine the threshold range based on a determination by the second determination module.

7. The mobile apparatus of claim 3, further comprising a second determination module configured to determine whether the mobile apparatus is in a sleep state or not, wherein the first determination module is configured to determine the threshold range based on a determination by the second determination module.
