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.
