Abstract

In an information processing device, when a positional information acquiring unit acquires positional information calculated from GPS signals and the like, a movement area setting unit sets a movement area with a size corresponding to a distance between a current location and a destination. When the positional information acquiring unit acquires positional information indicating a current location after setting this movement area, a judgment unit judges whether the positional information is within the movement area. Then, as a result of this judgment, in a case of being within the movement area, a display control unit executes display control of a display unit so as to display on a map the positional information, and in a case of being outside of the movement area, so as not to display on the map the positional information.

Claims

1. An information processing device, comprising:

a destination setting unit that sets a destination;

a positional information acquiring unit that acquires positional information indicating a current location of the information processing device measured based on a plurality of signals received at a predetermined time interval;

a movement area setting unit that acquires a movement area that is set based on the positional information acquired by the positional information acquiring unit and positional information of the destination;

a judgment unit that judges whether positional information of a current location acquired by the positional information acquiring unit after setting of the movement area acquired by the movement area setting unit is within a movement area acquired by the movement area setting unit; and

a display control unit that displays the current location on a predetermined display unit when the judgment unit judges that the positional information of the current location is within the movement area, and does not display the current location on the display unit when the judgment unit judges that the positional information of the current location is outside the movement area.

2. The information processing device according to claim 1, further comprising:

a moving operation unit that moves a map displayed on the display unit; and

a display scale size operation unit that enlarges/reduces a size of a map displayed on the display unit,

wherein, in a case in which a scale size of map information, displayed to be enlarged in accordance with an enlarging operation after an operation through the moving operation unit, is at least a predetermined size relative to a state previously displaying map information on the display unit, the destination setting unit sets a center location of the map information being displayed thereon as a destination.

3. The information processing device according to claim 1,

wherein the movement area setting unit sets a size of the movement area based on a distance between the positional information acquired by the positional information acquiring unit and positional information of the destination.

4. The information processing device according to claim 1,

wherein the movement area setting unit sets a size of the movement area based on positioning accuracy of the positional information acquired by the positional information acquiring unit.

5. The information processing device according to claim 1,

wherein the movement area setting unit sets a size of the movement area based on a travelling speed that indicates a change in the positional information acquired at the predetermined time interval.

6. The information processing device according to claim 1,

wherein the movement area setting unit sets the movement area at a specific time interval.

7. The information processing device according to claim 1,

wherein the movement area setting unit sets the movement area at a time interval corresponding to a travelling speed that indicates a change in the positional information acquired at the predetermined time interval.

8. The information processing device according to claim 1,

wherein the movement area setting unit sets the movement area according to a distance between positional information of a current location and positional information of the destination.

9. The information processing device according to claim 1,

wherein the movement area setting unit sets the movement area at a time interval corresponding to a relationship between a distance between positional information of a current location and positional information of the destination and a travelling speed indicating a change in the positional information acquired at the predetermined time interval.

10. The information processing device according to claim 1,

wherein the movement area setting unit sets a size of the movement area when the positional information acquiring unit acquires the positional information with at least a predetermined level of accuracy.

11. A storage medium encoded with a computer-readable program that enables a computer to execute functions as:

a destination setting unit that sets a destination;

a positional information acquiring unit that acquires positional information indicating a current location of the computer measured based on a plurality of signals received at a predetermined time interval;

a movement area setting unit that acquires a movement area that is set based on the positional information acquired by the positional information acquiring unit and positional information of the destination;

a judgment unit that judges whether positional information of a current location acquired by the positional information acquiring unit after setting of the movement area acquired by the movement area setting unit is within a movement area acquired by the movement area setting unit; and

a display control unit that displays the current location on a predetermined display unit when the judgment unit judges that the positional information of the current location is within the movement area, and does not display the current location on the display unit when the judgment unit judges that the positional information of the current location is outside the movement area.
