Abstract

An electronic device configured to detect arrival at a specified location, includes: a location information acquisition unit configured to acquire current location of the electronic device; a detection range setting unit configured to set detection ranges for detecting arrival of the electronic device at specified locations given the order; and a detection range control unit configured to change the detection ranges according to location status of the electronic device based on relationship between the current location and the specified locations.

Claims

1. An electronic device comprising:

a location information acquisition unit configured to acquire a current location of the electronic device;

a route setting unit configured to set a plurality of specified locations having an order of arrival;

a detection range setting unit configured to set detection ranges for detecting arrival of the electronic device at the plurality of specified locations; and

a detection range control unit configured to change the detection ranges according to a movement status of the electronic device that is determined by differences between estimated times of arrival of the electronic device at the plurality of specified locations and a current time.

3. The electronic device according to claim 1, wherein the detection range control unit is further configured to change sizes of the detection ranges.

4. The electronic device according to claim 1, wherein the detection range control unit is further configured to reduce the detection ranges when the current location has departed from the detection ranges.

5. The electronic device according to claim 1, wherein the detection range control unit is further configured to enlarge the detection ranges when the current location has entered the detection ranges.

6. The electronic device according to claim 1, wherein the detection range control unit is further configured to change shapes of the detection ranges.

9. The electronic device according to claim 1, further comprising:

an arrival determination unit configured to determine whether or not the electronic device has arrived within the detection ranges set by the detection range setting unit.

10. The electronic device according to claim 1, wherein the detection range setting unit is configured to set a different detection range for detecting the arrival of the electronic device at each of the plurality of specified locations.

2. An electronic device comprising:

a location information acquisition unit configured to acquire a current location of the electronic device;

a route setting unit configured to set a plurality of specified locations having an order of arrival;

a detection range setting unit configured to set detection ranges for detecting arrival of the electronic device at the plurality of specified locations; and

a detection range control unit configured to change the detection ranges according to a location status of the electronic device that is determined by distances between the specified locations and the current location.

7. An arrival determination method executed by an electronic device, the method comprising:

acquiring a current location of the electronic device;

setting a plurality of specified locations having an order of arrival;

setting detection ranges for detecting arrival of the electronic device at the plurality of specified locations; and

changing the detection ranges according to a movement status of the electronic device that is determined by differences between estimated times of arrival of the electronic device at the plurality of specified locations and a current time.

8. A non-transitory computer-readable recording medium having a program recorded thereon for controlling an electric device to execute:

a location information acquisition function to acquire a current location of the electronic device;

a route setting function to set a plurality of specified locations having an order of arrival;

a detection range setting function to set detection ranges for detecting arrival of the electronic device at the plurality of specified locations; and

a detection range control function to change the detection ranges according to a movement status of the electronic device that is determined by differences between estimated times of arrival of the electronic device at the plurality of specified locations and a current time.
