A document is divided into a plurality of regions so that each page has a meaning and, for each of the regions, there is generated a similarity table indicating a similarity degree and a data amount corresponding to the multiplexed resolution level data. By referencing this similarity table, each page of the electronic document in the region specified by the user is represented by a predetermined similarity (resolution) and at the reading speed specified by the user. Moreover, by referencing the similarity table, each page of the electronic document is represented at the maximum speed while guaranteeing the predetermined similarity.

Electronic document reading system and method

In an in-space viewpoint control device, a viewpoint control means comprises a recommend vector setting means, a viewpoint information determination means, a viewing point order calculation means, a viewpoint pass generating means, and a relevant information visualization control means. The recommend vector setting means sets recommend vectors for the object which reflects the intentions of the content designer. The viewpoint information determination means is determines a viewing direction and a viewpoint position in the space for viewing the object on the basis of the recommend vector information. The viewing point order calculation means is responsive when a plurality of recommend vectors are being set, as it determines a rotation order for each viewing point being determined in accordance with the recommend vector. The viewpoint pass generating means calculates an appropriate shifting pass for the viewing point following the calculated rotation order, such that the viewing point is shifted smoothly. The relevant information visualization control means is responsive to the user's decision of having relevant information displayed along with the object, as it controls their disposition, the place and direction of the viewing point such that they do not interfere with each other.
