Abstract: An evaluation system which can quantitatively evaluate a virtually produced workspace by adequately providing conditions of an operator and the workspace. The system calculates a motion of the operator on the basis of the input conditions of the operator and the workspace, and a task sequence in the workspace, and displays data for evaluation of the calculated motion of the operator.

Abstract: A presentation support environment system. Logical natures and constraints of arrangements, structures, or the like of elements (components and backgrounds) constituting a presentation reference, semantic natures and constraints obtained by causing men to sense these elements, and quantitative natures and constraints of the elements are prepared as knowledge in a system in advance. A drafter (presenter) of the presentation reference designates content items and attributes of the presentation reference. These points are emphasized in the content, a degree of emphasis (priority), by designating the items and attributes. Parameters for specifying various components and backgrounds constituting the presentation reference are determined such that various constraints of the system are satisfied. A practical presentation reference is generated in accordance with the parameters. The natures and constraints of the elements constituting the presentation reference are expressed to have a plurality of solutions.

Abstract: On the basis of, e.g., input items, attribute values, and titles, their categories are analyzed by using a proper noun dictionary, a concept dictionary, and a numeric attribute name dictionary. On the basis of the analyzed categories, changes in attribute values are analyzed in accordance with inference rules, and a keyword for describing a background state of presentation is extracted. A background material suitable for presentation is selected from background materials such as images and sounds in accordance with the extracted keyword. The selected background material is displayed in combination with a graph which is formed in accordance with content data about an object to be presented.
