Paragraph Number

84

The degree to which the navigation system factor 406 defines or influences the context 400 can be predefined based on a set of default navigation system types. Alternatively, or in addition, the degree to which the navigation system factor 406 defines or influences the context 400 can be set, determined, or adjusted by a user. In one embodiment, if the navigation system is a system integrated into a public train, the navigation system factor 406 may have a lower influence than if the navigation system is a system implemented using a portable device owned by the user. In one embodiment, an orientation mode for a navigation system on a portable electronic device of the user for a particular user may be heading up orientation mode because the user has more control of the navigation and can alter the route more readily.
