As thus far described therefore, the vehicle operator need only note the
distance and direction between the two light dots 14 and 15 on the screen as
the vehicle proceeds from location to location, and control the vehicle
heading so as to continually or incrementally head toward the selected end
destination. Returning to FIG. 1, the vehicles compass heading can be
shown by a heading display vector 18 on the screen 11 (provided by an
electronic compass 17 energizing the receiver 10.)
In operation, as the vehicle proceeds from each location to the next, the
light dot 14 shows such movement on the screen 11 to continually show the
vehicle location on map displayed on the screen, or merely its X-Y
coordinate location on the screen 11 without a map display. Whenever, the
vehicle deviates from a correct heading direction, due to traffic congestion,
road repairs, accidents, or any other reason, the dots 14 and 15 on the screen
11 diverge away from each other, and a new directional heading is required
to be followed by the vehicle to reach its selected destination.
Thus, the claim does require displaying only two markings corresponding to the
changeable location of the vehicle and the selected destination without showing any
routing path interconnecting the two markings.
Now the question before us is what Asano and Ohmura would have taught to one of
ordinary skill in the art? To answer this question, we find the following facts:
1. Asano states at column 6, lines 34-66 that:
In FIG. 4, the route from the present position to the destination has ten
roads and nine branching points. These roads and branching points are
related to road numbers, road names and branching point names, as shown
in FIG. 5.
As shown in FIG. 6, the route information screen indicates not only the
distances between the branching points (indicated by circles) on the routes
from the present position to the destination, but also the names of the roads
and branching points in the route. This example is derived from the data
shown in FIG. 5.
FIGS. 7(a) to 7(c) show the searched route on a entire route map screen
(FIG. 7(a)) and shows the screen transitions for acquiring the route
information. The entire route map screen, as designated at 6 in FIG. 7(a),
is formed with a map display panel 60 on which is displayed a determined
route 63, extending from the present position of the vehicle, as indicated by
