Abstract:
1. A portable electronic device, the device comprising: a controller; and a display, the controller being configured to receive vector data representing a position of a user of the portable device from a satellite positioning sensor associated with the user, receive scalar data representing movement of the user from at least one motion sensor associated with the user, store data based on the vector data, and feed a scalar parameter proportional to the scalar data to the display, the display being configured to display the scalar parameter, the vector data comprising satellite positioning data, the scalar data being a numerical value, the scalar parameter proportional to the scalar data comprising at least one of an average speed, an instantaneous speed, and a distance traveled along a path of the user, the controller being configured to detect a failure to receive the scalar data from the at least one motion sensor, form the scalar parameter on the basis of the vector data on position, and feed the scalar parameter to the display in response to the failure.
