`US 2003/0195695 Al Oct. 16, 2003
`
`
`
`
`
`
`
`A portable terminal has a function of walking navigation.
`
`
`
`
`
`
`The direction of a destination is displayed by an indicating
`
`
`
`arrow that always points in the direction of the destination.

`
`
`Internet map information services only as a single unit. The

`

`that the maps can be displayed at a resolution equivalent to

`
`
`above described services will not yet be easier for the users

`
`
`
`confronted with a problem that the maps, when displayed on

`Under such circumstances, it is an object of the present
`
`
`

`
`
`
`walking navigation, which can supply location information
`
`
`
`In addition, the map retrieving method employed for the
`
`
`
`
`easier for the user to understand during walking with use of
`
`
`
`
`above described services requires an enormous amount of
`
`
`
`

`
`

`
`
`
`suitable for walking navigation systems. For example, in the

`of retrieving conditions intuitively.
`If text is entered and/or menus are selected to narrow those
