  • Publication number: 20050015197
    Abstract: A communication type navigation system which presents information supporting judgement of a route selection when a user selects a guidance route from a plurality of searched and recommended routes. In response to a route search request from a navigation terminal (60), a navigation information providing server (10) performs a route search and selects a plurality of recommended routes. By using the information (traffic information, weather information, facility information and user profile information) managed and held by the navigation information providing server (10), evaluation information is generated for the plurality of selected and recommended routes. A user at the navigation terminal (6) is made to refer to this evaluation information and to select a desired recommended route from the plurality of recommended routes.

  • Patent number: 4561723
    Abstract: An electronic stereoscopic viewing device has an electronic signal generator which is coupled electronically to a liquid crystal display screen. The display screen upon receipt of a signal from the signal generator displays first and second views of an image with the first and second images being parallactically displaced with respect to one another. A first optical pathway conducts the first parallactically displaced view to a left eye viewing port and a second optical pathway conducts the second parallactically displaced view to a right eye viewing port. The optical pathways between the display screen and the left and right eye viewing ports are such that the first and second images are conducted to the respective left and right eye viewing ports in a manner maintaining the integrity of each such that the individually parallactically displaced first and second views of the images are received at the respective left and right eye viewing ports without contamination of one by the other.
