Device and medium for determining a movement state
A mobile device according to one aspect includes an acceleration sensor configured to detect an acceleration value, and a controller configured to determine between a moving state and a non-moving state, based on the acceleration value. The controller changes sensitivity of the acceleration sensor between the moving state and the non-moving state.
1. A mobile device comprising:
an acceleration sensor configured to detect an acceleration value; and
a controller configured to determine between a moving state and a non-moving state, based on the acceleration value,
wherein
the controller is configured to change a measurement range of the acceleration sensor between the moving state and the non-moving state, and
the controller is configured to:
change the measurement range of the acceleration sensor to maximum based on a determination that the moving means corresponds to walking, and
change the measurement range of the acceleration sensor to maximum based on a determination that the moving means corresponds to bicycling.
2. The mobile device according to claim 1 , wherein
the controller includes
a first controller configured to determine between a moving state and a non-moving state based on the acceleration value, and
a second controller configured to change the measurement range of the acceleration sensor between the moving state and the non-moving state.
3. The mobile device according to claim 1 , wherein
the controller determines by which means of a plurality of moving means the mobile device is moving, as the moving state, and
changes the measurement range of the acceleration sensor to a different measurement range in at least two of the plurality of moving means.
4. The mobile device according to claim 1 , wherein the controller sets the measurement range of the acceleration sensor to maximum range to perform tumbling detection of a user of the mobile device when the moving means corresponds to walking or bicycling.
5. The mobile device according to claim 1 , wherein the controller notifies the detection of tumbling to a preset contact address in response to the detection of tumbling.
6. The mobile device according to claim 1 , wherein the controller is configured to change the measurement range of the acceleration sensor to less than maximum based on a determination that the moving means is other than walking and bicycling.
7. A non-transitory computer readable recording medium storing thereon a control code that causes a mobile device including an acceleration sensor that detects an acceleration value to perform the steps of:
determining between a moving state and a non-moving state based on the acceleration value;
changing a measurement range of the acceleration sensor between the moving state and the non-moving state,
changing the measurement range of the acceleration sensor to maximum based on a determination that the moving means corresponds to walking, and
changing the measurement range of the acceleration sensor to maximum based on a determination that the moving means corresponds to bicycling.
8. The non-transitory computer readable recording medium according to claim 7 , wherein the control code causes the mobile device to perform the step of:
changing the measurement range of the acceleration sensor to less than maximum based on a determination that the moving means is other than walking and bicycling.
9. A mobile device comprising:
an acceleration sensor configured to detect an acceleration value; and
a controller configured to determine between a moving state and a non-moving state, based on the acceleration value,
wherein
the controller sets a first measurement range of the acceleration sensor when the controller determines the moving state,
the controller sets a second measurement range that is different from the first measurement range when the controller determines the non-moving state,
the controller is configured to change the measurement range of the acceleration sensor to maximum based on a determination that the moving means corresponds to walking, and
the controller is configured to change the measurement range of the acceleration sensor to maximum based on a determination that the moving means corresponds to bicycling.
10. The mobile device according to claim 9 , wherein the controller is configured to change the measurement range of the acceleration sensor to less than maximum based on a determination that the moving means is other than walking and bicycling.
