Device for Course Indication to Aid in Navigation
First Claim
1. A navigation aid device for use when a predetermined route is followed, said route extending from a starting point along a series of break points up to a destination being the last break point, such that the route is formed by connecting said point with mainly straight sections, comprising:
- an elongated course indication unit extending on either side of a fixed center point and being adapted to indicate any necessary course adjustments by displacing an appearance pattern to the left or to the right relative the center point, said course indication unit being adapted to show whether it is necessary to correct the course, by the appearance pattern containing at least one central area located nearest to the center point having a first appearance (“
o”
) and two areas located on either side having a second appearance (“
x”
), and a distance indication unit being adapted to indicate how far it is up to the next break point, wherein the central area having the first appearance is shown relatively wide in the course indication unit when greater course deviations can be tolerated, and more narrow when the course must be kept more precisely.

Abstract
A navigation aid device for use when a predetermined route is followed, said route extending from a starting point along a series of break points up to a destination being the last break point. The device comprises an elongated course indication unit extending on either side of a fixed center point and indicating any necessary course adjustments by displacing an appearance pattern to the left or to the right relative the center point. A distance indication unit indicates how far it is up to the next break point. A central area in the appearance pattern is shown relatively wide in the course indication unit when greater course deviations can be tolerated, and is shown narrower when the course must be kept more precisely.
