Abstract: A navigation apparatus includes a receiving section for receiving program via a communication unit, a driving determining section for determining whether a vehicle equipped with the navigation apparatus is running or not if receiving a start request for the program, and an execution control section for activating the program if it is determined that the vehicle is running by the driving determining section and also if the program received by the receiving section is authorized. The executing control section cancels executing the program if it is determined that the vehicle is running by the driving determining section and also if the program received by the receiving section is not authorized.

Abstract: The object of the invention is to execute a program installed additionally on an in-vehicle unit, realizing improved visual recognition while the vehicle is driving. A program 7 to be installed additionally is downloaded along with its attribute data 8 from the service center system 10 into the program administrating section 202 of the in-vehicle unit, and they are managed in relation to each other. When the program is executed, the vehicle condition 1 is compared with the attribute data 8 related to the program and the program operation is controlled accordingly. When executing a program installed additionally on an in-vehicle unit, visual recognition of the display screen can be maintained even while the vehicle is driving.

Abstract: An adaptive information display apparatus is provided for simultaneously displaying a plurality of kinds of display information on a display screen in an optimal display form. The information display apparatus includes a work processing unit for executing a plurality of kinds of work processing based on each of data inputted from a sensor input unit and a character/coordinate input unit and outputting the results of the work processing, and a display unit for displaying the results of the plurality of kinds of work processing outputted from the work processing unit. The information display apparatus further includes a display form detector unit detecting display form data for the display unit, an arrangement rule storage unit storing an arrangement rule defining display forms corresponding to each of the plurality of kinds of work processing, and a display arrangement control unit comparing the display form data and the arrangement rule for each work to output a predetermined display arrangement instruction.

Abstract: A method for indicating positions of moving bodies located in a specific area, includes detecting a current position or positions of one or more moving bodies located in the specific area; and displaying a layout diagram of specific objects located in the specific area and information symbolical of each of the moving bodies at positions in the layout diagram which is displayed. The positions of the moving bodies in the displayed layout diagram is determined on the basis of the detected current positions of the moving bodies.

Abstract: A mobile control system capable of identifying a layout condition at a glance and quickly finding and displaying an associated moving body from among many moving bodies, wherein the system is capable of retrieving an object of communication by only designating a site and quickly making communication with the object thus picked out. For controlling moving bodies located in a specific area, the mobile control systems are each provided with a position sensor for detecting a current position or positions of one or more moving bodies located in the specific area and a monitor system for displaying a layout diagram of specific objects located in the specific area and information symbolical of the moving bodies respectively at positions determined on the basis of the current positions of the moving bodies detected by the position sensor in the layout diagram being displayed.
