Abstract
Abstract A navigation device includes a platform having hardware including at least a user operation unit and a map database, and basic functions to control the hardware. The navigation device also includes an application processing unit for providing navigation services using the basic functions of the platform, and a platform-dependent unit for, when transferring information from the platform to the application processing unit, transferring the information in a constant format, and for, when transferring information from the application processing unit to the platform, transferring it in a certain format which depends on the platform. The map database holds map data in a predetermined recording format. The navigation device can further include a map-database-dependent unit for receiving map data, which is read from the map database by the platform-dependent unit, and for supplying the received map data to the application processing unit in the constant format. The navigation device can also include a user-interface-dependent unit for receiving data corresponding to a user's operation, which is read from the user operation unit by the platform-dependent unit, and for supplying the received data to the application processing unit in the constant format.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A navigation device comprising: a platform having hardware including at least user operation means and a map database, and an operating system to control the hardware; application processing means for providing navigation services using the operating system; platform-dependent means for, when transferring information from the platform to the application processing means, transferring the information in a platform-independent format, and for, when transferring information from the application processing means to the platform, transferring the information in a platform-dependent format which depends on the platform; and user-interface-dependent means for receiving platform-dependent data corresponding to a user's operation read from the user operation means by said platform-dependent means, and for supplying the data received to the application processing means in the platform-independent format, wherein the platform-dependent means isolates the application processing means from the platform so the application processing means runs independently of the platform.
Claim 2
Dependent Claim
142 words
A navigation device comprising: a platform having hardware including at least user operation means and a map database, and an operating system to control the hardware; application processing means for providing navigation services using the operating system; platform-dependent means for, when transferring information from the platform to the application processing means, transferring the information in a platform-independent format, and for, when transferring information from the application processing means to the platform, transferring the information in a platform-dependent format which depends on the platform; and user-interface-dependent means for receiving platform-dependent data corresponding to a user's operation read from the user operation means by said platform-dependent means, and for supplying the data received to the application processing means in the platform-independent format, wherein the platform-dependent means isolates the application processing means from the platform so the application processing means runs independently of the platform.
Claim 3
Dependent Claim
57 words
The navigation device according to claim 1 , wherein said map database holds map data in a fixed recording format, and said device further comprises map-database-dependent means for receiving platform-dependent map data read from said map database by the platform-dependent means, and for supplying the map data received to the application processing means in the platform-independent format.
Claim 4
Dependent Claim
70 words
A navigation device comprising: a platform having hardware including at least user operation means and a map database, and an operating system to control the hardware; application processing means for providing navigation services using the operating system; and user-interface-dependent means for receiving platform-dependent data corresponding to a user's operation read from the user operation means, and for supplying the data received to the application processing means in a platform-independent format.
Claim 5
Dependent Claim
70 words
A navigation device comprising: a platform having hardware including at least user operation means and a map database, and an operating system to control the hardware; application processing means for providing navigation services using the operating system; and user-interface-dependent means for receiving platform-dependent data corresponding to a user's operation read from the user operation means, and for supplying the data received to the application processing means in a platform-independent format.
Claim 6
Dependent Claim
130 words
A navigation device comprising: a platform having hardware comprising at least a microprocessor, user operation means, and a storage device; and a navigation operating system including instructions for controlling the hardware; a navigation application module isolated from the platform, and including a plurality of navigation applications; and a platform-dependent module including a graphics display module for supplying platform-dependent image display instructions to the navigation operating system, a map file access module for supplying platform-dependent storage device access instructions to the navigation operating system, and a sensor data receiving module for supplying platform-dependent sensor data request instructions to the navigation operating system, wherein the navigation applications, using the platform-dependent module, control the hardware by translating platform-independent instructions received from the navigation applications to platform-dependent instructions supplied to the navigation operating system.
Claim 7
Dependent Claim
130 words
A navigation device comprising: a platform having hardware comprising at least a microprocessor, user operation means, and a storage device; and a navigation operating system including instructions for controlling the hardware; a navigation application module isolated from the platform, and including a plurality of navigation applications; and a platform-dependent module including a graphics display module for supplying platform-dependent image display instructions to the navigation operating system, a map file access module for supplying platform-dependent storage device access instructions to the navigation operating system, and a sensor data receiving module for supplying platform-dependent sensor data request instructions to the navigation operating system, wherein the navigation applications, using the platform-dependent module, control the hardware by translating platform-independent instructions received from the navigation applications to platform-dependent instructions supplied to the navigation operating system.
