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.

Abstract: The present invention discloses an integrated touch screen control system implemented in an automobile. The touch screen control system includes a touch screen device having a pressure sensitive screen for converting at least one pressured point thereon into at least one control signal representing a location thereof. A controlled device structurally separated from the touch screen device performs at least one predetermined function in response to the control signal. Interfacing means is eclectically or optically coupled between the touch screen device and the controlled device for sending the control signal from the touch screen device to the controlled device.
