GPS ODOMETER
First Claim
1. A system configured to be transported, carried or worn by a user, comprising:
- a location determining device for determining the location of the user at a plurality of times during a journey from a first location to a second location;
at least one motion sensor for determining a motion state of the user at a plurality of times during the journey; and
a processor coupled to the location determining device and the at least one motion sensor, said processor being arranged to determine the distance travelled by the user during at least a portion of the journey using the plurality of determined locations and the plurality of determined motion states.

Abstract
A system is provided that is configured to be transported, carried or worn by a user, such as a portable personal training device or sports watch. The system comprises means for determining the location of the user at a plurality of times during a journey from a first location to a second location, such as a GPS receiver. The system further comprises means for determining a motion state of the user at a plurality of times during the journey. The means can include an accelerometer, and can also utilise data obtained from a GPS receiver. The system further comprises means for determining the distance travelled by the user during at least a portion of the journey using the plurality of determined locations and the plurality of determined motion states, such that the system functions as an odometer.

14. A system configured to be transported, carried or worn by a user, comprising:
-
a location determining device for determining the location of the user at a plurality of times during a journey from a first location to a second location; a speed determining device for determining the speed of the user at a plurality of times during the journey; at least one motion sensor for determining a motion state of the user at a plurality of times during the journey; and a processor coupled to the location determining device, the speed determining device and the at least one motion sensor, said processor being arranged to determine the distance travelled by the user during at least a portion of the journey by selectively using the plurality of determined locations or the plurality of determined speeds based on the determined motion state of the user. - View Dependent Claims (15)

17. A method of determining the distance travelled by a user during at least a portion of a journey from a first location to a second location using a system configured to be transported, carried or worn by a user, the method comprising:
-
determining the location of the user at a plurality of times during the journey; determining a motion state of the user at a plurality of times during the journey; and using the plurality of determined locations and the plurality of determined motions states to determine the distance travelled by the user.

18. A method of determining the distance travelled by a user during at least a portion of a journey from a first location to a second location using a system configured to be transported, carried or worn by a user, the method comprising:
-
determining a motion state of the user at a plurality of times during the journey; and selectively using one of;
(i) a plurality of locations of the user during the journey; and
(ii) a plurality of speeds of the device during the journey, to determine the distance travelled by the user based on the determined motion states of the user.
