A driving support system including: a vehicle location detector which detects current location and velocity vector of a vehicle; a traffic and road information database which stores point information of points on a route of the vehicle; a point information acquisition unit which acquires, from the database, the point information of the approaching points located in a given distance from the vehicle current location, based on the detected vehicle current location and velocity vector; a display device which provides displays of the acquired point information on a horizontally long screen thereof along a windshield of the vehicle; and a display control unit for controlling the display device. The display control unit determines display positions on the screen to display the point information, based on a positional relationship between the current location of the vehicle and the points where the point information related thereto are displayed.

A navigation system, portable information processing device and its control program, data server, information processing server, navigation method, traveling route establishing method, information providing method, and area information providing method are disclosed having a portable terminal () to read out code data, indicative of area information of a destination and routed spots, from a print product (). The code data are converted into area information and stored in a storage unit (), from which particular area information is retrieved and transmitted to an on-vehicle navigation device () by which a traveling route of the vehicle is established on the basis of area information to guide the vehicle to the destination.

Navigation system, data server, traveling route establishing method and information providing method

A content providing area presentation system is configured to present content providing area candidates to enable a user to readily select an appropriate content providing area when at least one of the content providing area candidates is presented to the user. The content providing area presentation system comprises a user inputting section and a displaying section. The user inputting section is configured and arranged to request content providing area candidates for presenting at least one of the content providing area candidates to a user based on a selection criterion. The displaying section is configured and arranged to display the at least one of the content providing area candidates in response to the selection criterion established by the user inputting section.

Content providing area presentation system

A contents reproduction system includes a reproducing section to reproduce a content received via telecommunication when the receiving condition is in an acceptable state, and to reproduce one of recorded contents stored in a storage section when the receiving condition is in an unacceptable state. A preference discriminating section determines a preference of a user by examining at least one content selected by a user for reproduction. A contents selecting section selects one, as a reserve content, from the contents stored in the storage section in accordance with the preference and supplies the reserve content to the reproducing section for reproduction instead of the received content when the receiving condition is in the unacceptable state.

Contents reproduction system and process

In communications control apparatus and method for an automotive vehicle, a buffer enabling quantity by which data of the requested content is enabled to be buffered into a receiving buffer during a vehicular run on the traveling scheduled route is calculated using a traveling time and a communication speed; and a capacity of the receiving buffer is set according to a calculated result of the buffer enabling quantity calculation described above and an upper limit value of the receiving buffer capacity, data on a requested content being downloaded onto the receiving buffer whose capacity is set.

Communications control apparatus and method for automotive vehicle

A navigation system includes a map-gain timing judging part to calculate a traveling speed the position of a vehicle detected by a GPS unit A moving distance of the vehicle during the renewal of map is calculated by the traveling speed and a renewal time necessary for gaining the map information from the server of a map information delivery apparatus The system further calculates a traveling direction of the vehicle by the position of the vehicle and also calculates a road distance from the present position of the vehicle to the margin of a map on display. When the road distance agrees with moving distance, it is started to gain a new map information from the server. Thus, when the vehicle reaches the margin of the map on display, the renewal of the map information is completed.

Navigation system for vehicle

A navigation system, portable information processing device and its control program, data server, information processing server, navigation method, traveling route establishing method, information providing method, and area information providing method are disclosed having a portable terminal ( ) to read out code data, indicative of area information of a destination and routed spots, from a print product ( ). The code data are converted into area information and stored in a storage unit ( ), from which particular area information is retrieved and transmitted to an on-vehicle navigation device ( ) by which a traveling route of the vehicle is established on the basis of area information to guide the vehicle to the destination.

A map information providing apparatus includes a detecting unit and a searching part In operation, the part searches a target object in accordance with a position of a user's vehicle detected by the detecting unit A positional relationship analyzing part analyzes a positional relationship between the target object and the user's vehicle. A reduced scale calculating part calculates a reduced scale of the map information on the basis of the positional relationship analyzed by the part and a display format of an onboard monitor Further, the apparatus picks up the map information with the calculated reduced scale allowing the vehicle and the target object to be displayed on the monitor simultaneously.

Map information providing apparatus and method

A sighting direction detecting device including a TV camera which is disposed to face a human being and picks up an image of light invisible to human beings, a first illuminator which is disposed in a coaxial system with the TV camera and illuminates a human's eye-ball portion with light which is invisible to human beings, a second illuminator which is disposed at a different place from the first illuminator and illuminates the human's eye-ball portion with light which is invisible to human beings, a first calculator for calculating an equation of a line passing the pupil center position of the eye-ball, an equation of a line passing the reflected-light position of the first illuminator and an equation of a line passing the reflected-light position of the second illuminator on the basis of the image which is picked up by the camera, a second calculator for calculating the center position of a cornea ball on the basis of the equation of the line passing the reflected-light position of the first illuminator and the equation of the line passing the reflected-light position of the second illuminator which are calculated by the first calculator, and a third calculator for calculating the sighting direction of the human being on the basis of the equation of the line passing the pupil center position detected by the first calculator and the center position of the cornea ball which is calculated by the second calculator, wherein the image obtained by the TV camera comprises a first image obtained under illumination of the first illuminator and the second illuminator and a second image obtained under illumination of illumination means which does not contain the first illuminator.
