NAVIGATION SYSTEM WITH ASSISTANCE FOR MAKING MULTIPLE TURNS IN A SHORT DISTANCE
First Claim
1. A method of providing routing instructions in a navigation system, comprising:
- reviewing route information to a desired destination to determine at least two turns in sequence that are less than a predetermined distance apart; and
for the identified turns and, at an appropriate time in the route, announcing an oral combination instruction that includes the at least two turns and lane guidance.

Abstract
Techniques and tools are described for providing navigation assistance when there are multiple turns in succession in a short period of time or distance. In one embodiment, the route information can be reviewed to determine multiple turns in sequence that are less than a predetermined distance apart. These so-called “tight turns” can be handled differently than other turns by announcing the tight turns in a single combination instruction. Additional lane guidance can also be provided. In another embodiment, an audio feedback can be used to indicate that a user completed a successful turn. Such audio feedback can be in combination with the identified tight turns or independently for other turns or events. The audio feedback can also be an indication for the user to tap the display, wherein the tapping results in an immediate indication of the next turn.

11. A method of providing route instructions in a navigation system on a mobile phone, comprising:
-
receiving route and distance-between-turns data from a server computer; calculating a summation of distances between turns; identifying tight turns having the calculated summation less than a predetermined distance; grouping the tight turns into a single voice command so that multiple turns are announced prior to reaching the group tight turns; and listing each of the tight turns as a separate way point in written instructions on the user interface of the mobile phone. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system for providing route instructions in a navigation system on a mobile phone, comprising:
-
a map application; a positioning locator to locate a current position of the mobile phone, the positioning locator using one or more of the following for determining the current position;
satellite information, cell tower information, or wireless transmitter information;an operating system between the map application and the positioning locator for passing positioning information there between; wherein the map application receives route information including distances between turns and calculates tight turns that include two or more turns so that the tight turns can be announced as a single instruction together with lane guidance information. - View Dependent Claims (18, 19, 20)
