Abstract

An electronic timepiece includes an indicating hand, a distance display hand, a GPS receiver that receives satellite signals transmitted from GPS satellites, a magnetic sensor, and a controller. The controller determines the direction to a destination on the basis of the satellite signals received by the GPS receiver, the output from the magnetic sensor, and destination information representing the position of the destination, determines the distance to the destination on the basis of the satellite signals and the destination information, causes the indicating hand to indicate the direction to the destination, and causes the distance display hand to display the distance to the destination.

First claim

What is claimed is:

1. An electronic timepiece comprising:
a first indicating hand;
a second indicating hand;
a receiver that receives position identification information for identifying a current position;
a magnetic sensor; and
a controller that determines a direction to a destination based on the position identification information received by the receiver, an output from the magnetic sensor, and destination information representing a position of the destination and determines a distance to the destination based on the position identification information and the destination information,
wherein the first indicating hand indicates the direction to the destination, and the second indicating hand displays the distance to the destination.

2. The electronic timepiece according to claim 1 , wherein the controller switches, in accordance with the distance to the destination, a display range of the distance to the destination displayed with the second indicating hand.

3. The electronic timepiece according to claim 2 ,
further comprising a third indicating hand,
wherein the third indicating hand displays the display range.

4. An electronic timepiece comprising:
a first indicating hand;
a second indicating hand;
a receiver that receives position identification information for identifying a current position;
a magnetic sensor; and
a controller that determines a direction to a destination based on the position identification information received by the receiver, an output from the magnetic sensor, and destination information representing a position of the destination and determines a direction to north based on the output from the magnetic sensor,
wherein the first indicating hand indicates the direction to the destination, and the second indicating hand indicates the direction to north.

5. An electronic timepiece comprising:
an indicating hand;
a receiver that receives position identification information for identifying a current position;
a magnetic sensor; and
a controller that determines a direction to a destination based on the position identification information received by the receiver, an output from the magnetic sensor, and destination information representing a position of the destination and determines a direction to north based on the output from the magnetic sensor,
wherein the direction indicated with the indicating hand is switched between the direction to the destination and the direction to north.

6. The electronic timepiece according to claim 5 ,
further comprising an operation section that accepts a user's operation,
wherein when the operation section accepts the user's operation, the direction indicated with the indicating hand is switched between the direction to the destination and the direction to north.

7. The electronic timepiece according to claim 5 , further comprising a direction display section that displays the direction indicated with the indicating hand, the direction to the destination or the direction to north.

8. The electronic timepiece according to claim 1 ,
wherein the destination information is any of a plurality of pieces of positional information to each of which a number is given in advance, and
the electronic timepiece further comprises a number display section that displays the number given to positional information used as the destination information among the plurality of pieces of positional information.

9. The electronic timepiece according to claim 4 ,
wherein the destination information is any of a plurality of pieces of positional information to each of which a number is given in advance, and
the electronic timepiece further comprises a number display section that displays the number given to positional information used as the destination information among the plurality of pieces of positional information.

10. The electronic timepiece according to claim 5 ,
wherein the destination information is any of a plurality of pieces of positional information to each of which a number is given in advance, and
the electronic timepiece further comprises a number display section that displays the number given to positional information used as the destination information among the plurality of pieces of positional information.

11. The electronic timepiece according to claim 8 ,
wherein each of the plurality of pieces of positional information is information representing a position on a single path, and
the numbers are numbers according to an order in accordance with which the positions indicated by the plurality of pieces of positional information are arranged along the path.

12. The electronic timepiece according to claim 9 ,
wherein each of the plurality of pieces of positional information is information representing a position on a single path, and
the numbers are numbers according to an order in accordance with which the positions indicated by the plurality of pieces of positional information are arranged along the path.

13. The electronic timepiece according to claim 10 ,
wherein each of the plurality of pieces of positional information is information representing a position on a single path, and
the numbers are numbers according to an order in accordance with which the positions indicated by the plurality of pieces of positional information are arranged along the path.
