Apparatus and method for presenting navigation information based on instructions described in a script

Abstract

A navigation script includes time and point information for navigation and information for guidance, and describes an instruction sequence which can represent these information in time series in a mark-up language. According to the structured data generated from the navigation script, an instruction corresponding to a current time or point is executed, so that information for guidance to be presented is output.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a navigation information presenting apparatus for providing navigation information of a route, etc. by using a markup language description and a method thereof, and more particularly to a technique which is applied to car navigation systems, personal computers, PDA (Personal Digital Assistant), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), etc., and is available for providing route information or additional information such as route navigation, sightseeing information, a delivery plan, a travel plan, traffic control, scheduling, an amusement, a municipal service, etc. via a network or an electronic medium.[0003] 2. Description of the Related Art[0004] With conventional navigation information services, for example, if a point desired to be navigated is specified, the data about that point are listed and presented in many cases. Additionally, their contents include only the geographic informat...

Problems solved by technology

Furthermore, with a conventional car navigation system, when a departure point, a destination, enroute spots, etc. are set, an appropriate route is selected based on map information, and only geographic information is output while a car is running, thus it is impossible to output additional information for navigation and guidance at a particular time and / or point.

Besides, in a conventional navigation information service, a data list relating to a place to be presented appears to be uneasy to understand.

Additionally, since the contents of described data include only the information about a specified point, it is impossible to flexibly guide the route reaching that point or en-route spots.

Furthermore, because data of the conventional navigation information service are provided in a format which is different depending on each system, navigation information are difficult to be reciprocally used.

For instance, although point information services can be provided in a car navigation system or a PHS (Personal Handyphone System), their data cannot be shared by the systems.
