System for creating structured fields on electronic forms

InactiveUS6137488AGreat efficiency and flexibility and powerFacilitates completely custom construction and completionData processing applicationsNatural language data processingGraphical user interfaceLogical relationship
A computer system enables a user to conveniently fill-out, configure, and submit a structure of interrelated data fields, where the order and type of linking between the fields is user selected. A graphical user interface presents a field template having one or more data fields. The user may extend the electronic form by selecting an expand form field; in response to selection of the expand field, the user interface adds a second field template and a connective field to the display. This second template, like the first, includes one or more data fields. Using a connective field, the user identifies a logical relationship between the first field template and the second field template. For instance, the user may select from Boolean or other connective terms to construct a form having a complex format of interrelated fields. As each new field template is added with its corresponding connective field, the user interface also presents a nesting icon, allowing the user to establish a logical hierarchy between the various field templates.

Method and apparatus for generating a bird's-eye view image

An obstacle detecting unit detects whether an obstacle exists in an area surrounding a vehicle in the direction a camera installed on the vehicle is pointed. If the obstacle is determined to have a portion at a predetermined height above a road surface with which the vehicle may make initial contact when the vehicle moves toward the obstacle, a virtual projection surface is set to the height of the predicted contact portion and viewpoint conversion processing is performed so as to project pixels of an image captured by the camera onto the virtual projection plane. In this way, the height of the projection plane and the height of the predicted contact portion match each other and the distance between the predicted contact portion and the vehicle is accurately expressed on a bird's-eye view image resulting from the viewpoint conversion.
