Multi-Function Apparatus and Related Method Integrated with Positioning/Orientation Mechanism
First Claim
1. A multi-function electronic apparatus with positioning/orientation mechanism capable of operating in a forward mode and a backward mode, wherein the forward mode indicates from a departure point to an end point, and the backward mode indicates from the end point to the departure point, the electronic apparatus comprising:
- a position module for detecting a current coordinate and a plurality of coordinates along a track which the electronic apparatus traveled;
a memory for recording the plurality of coordinates detected by the position module into a plurality of reference coordinates when the electronic apparatus is operating in a forward mode;
an orientation module for comparing the current coordinate and the reference coordinate of the memory when the electronic apparatus is operating in a backward mode; and
an orientation interface for providing a directional signal being utilized to indicate direction according the difference of the current coordinate and the reference coordinate.

Abstract
Multi-function apparatus and related method integrated with positioning/orientation mechanism. The apparatus of the invention works under a forward mode for recording reference coordinates/altitudes of a departure point and passing points along a track which a user moves. When the user wants to trace back, the apparatus works under a backward mode for comparing each of the recorded reference coordinates/altitudes with a current coordinate/altitude of the user, and providing direction/altitude orientation for the user so that the user can trace back to the original departure and/or passing points.
