Navigation and digital maps interface for fleet management anddriver information systems

摘要

Companies developing navigation and map technologies are facednwith the problem of providing products that can be utilized in the widenrange of emerging market applications. The author explores one company'snapproach in developing products with layered interfaces to meet thisnchallenge. Examples are given of fleet management and driver guidancensystems utilizing command layer interfaces. The simplicity of theninterface allows the applications developer to integrate navigation intona larger system with little up-front cost. Because the application doesnnot reside in the navigation device, the applications developer hasncomplete control over this project. This minimizes the complexity ofninterface and the interactions necessary to get his applicationnpublished on the navigation device's storage media
