Abstract

A mobile device comprises a communicator configured to communicate with another communication device; an acceleration sensor configured to detect an acceleration value; a direction sensor configured to detect a change of a direction of the mobile device; and at least one controller configured to determine number of steps of a user of the mobile device based on the acceleration value, and a direction of walking of the user based on the change of the direction of the mobile device to perform notification to the other communication device through the communicator when cumulative number of steps of the walking of the user in one of directions exceeds a first value.

First claim

What is claimed is:

1. A mobile device comprising:
a communicator configured to communicate with another communication device;
an acceleration sensor configured to detect an acceleration value;
a direction sensor configured to detect a change of a direction of the mobile device; and
at least one controller configured to
determine number of steps of a user of the mobile device based on the acceleration value, and a direction of walking of the user based on the change of the direction of the mobile device,
determine a first cumulative number of steps of the walking of the user in a first direction,
subtract a second cumulative number of steps in a second direction opposite to the first direction from the first cumulative number of steps to obtain a third cumulative number of steps,
perform notification to the other communication device through the communicator when the third cumulative number of steps exceeds a first value, and
stop notification to the other communication device through the communicator when the first cumulative number of steps exceeds the first value and the third cumulative number of steps fails to exceed the first value.

2. The mobile device according to claim 1 , wherein
the direction sensor is a geomagnetic sensor which is configured to detect a geomagnetism value.

3. The mobile device according to claim 1 , wherein
the direction sensor is an angular velocity sensor which is configured to detect an angular velocity value.

4. The mobile device according to claim 1 , further comprising:
a receiver configured to receive position information for specifying a position of the mobile device, wherein
the at least one controller is further configured to cause the receiver to receive the position information each time the number of steps exceeds a second value, and change the first value according to the position of the mobile device determined based on the position information.

5. The mobile device according to claim 4 , wherein, when the first value is changed according to the position of the mobile device,
the at least one controller is further configured to reset the cumulative number of steps for each of the directions to 0.

6. The mobile device according to claim 1 , wherein the first value is a value different for each direction.

7. The mobile device according to claim 1 , wherein the at least one controller is further configured to compare each of the cumulative numbers of steps in 4, 8, or 16 directions with the first value.

8. A control method of a mobile device including a communicator configured to communicate with another communication device, an acceleration sensor configured to detect an acceleration value, and a direction sensor configured to detect a change of a direction of the mobile device, the control method comprising:
determining number of steps of a user of the mobile device based on the acceleration value, and a direction of walking of the user based on the change of the direction of the mobile device;
determining a first cumulative number of steps of the walking of the user in a first direction;
subtracting a second cumulative number of steps in a second direction opposite to the first direction from the first cumulative number of steps to obtain a third cumulative number of steps;
performing notification to the other communication device through the communicator when the third cumulative number of exceeds a first value; and
stopping notification to the other communication device through the communicator when the first cumulative number of steps exceeds the first value and the third cumulative number of steps fails to exceed the first value.

9. The control method of a mobile device according to claim 8 , wherein the direction sensor is a geomagnetic sensor which is configured to detect a geomagnetism value.

10. The control method of a mobile device according to claim 8 , wherein
the direction sensor is an angular velocity sensor which is configured to detect an angular velocity value.

11. A non-transitory storage medium that stores a control program for causing, when executed by a mobile device including a communicator configured to communicate with another communication device, an acceleration sensor configured to detect an acceleration value, and a direction sensor configured to detect a change of a direction of the mobile device, the mobile device to execute:
determining number of steps of a user of the mobile device based on the acceleration value, and a direction of walking of the user based on the change of the direction of the mobile device;
determining a first cumulative number of steps of the walking of the user in a first direction;
subtracting a second cumulative number of steps in a second direction opposite to the first direction from the first cumulative number of steps to obtain a third cumulative number of steps;
performing notification to the other communication device through the communicator when the third cumulative number of steps exceeds a first value; and
stopping notification to the other communication device through the communicator when the first cumulative number of steps exceeds the first value and the third cumulative number of steps fails to exceed the first value.

12. The non-transitory storage medium according to claim 11 , wherein
the direction sensor is a geomagnetic sensor which is configured to detect a geomagnetism value.

13. The non-transitory storage medium according to claim 11 , wherein
the direction sensor is an angular velocity sensor which is configured to detect an angular velocity value.
