Only a part to this US map is shown in FIG.8A and the panning mode enables the user to see additional parts of the US. For instance, by adding one e-paper801 to the right side of e-paper 800, this user may be able to visualize on the added display interface 806 an image 811 corresponding to the central part of the American continent as illustrated in Fig.8B. By adding one more e-paper 802 as seen in FIG. 8C to the bottom of Epapers 800 and 801, an image 812 c orresponding to parts of Central America canalso be seenon the added display interface 807.

  • a distinct (i.e. additional) portion from the electronic document is associated to the newly discovered e-paper.
  • a match may be done between the actual size of the image, and the e-paper matrix's new configuration with the added e-paper. Based on this added e-paper area, position and orientation (identified through the contact sensors), the first device willbe able to identify the additional portion of the image (portions 811 and 812 in FTG.8B and 8C respectively) yet to be displayed on the added e- paper.

  • a new e-paper is added and there is no portion of the electronic document to display at that location, that e-paper may be blanked out. For example, reusing the map example of FlG. 8 A-C, if an e-paper were added below the South Pole, that e-paper would not display anything since there is nothing to be displayed at that Io c ation.

  • the present method does not require all the e-papersto be of the same physical dimensions.
  • the first e-paper will compute the smallest bounding rectangle that can include all the displays. It will use that bounding rectangle to determine the totalsize, and use the size and position of individual e- papers to determine the portion of image that must be displayed on each of those e -papers.

Abstract

La présente invention concerne un procédé permettant de partager un document électronique stocké sur un premier dispositif portable avec d'autres dispositifs portables. Le procédé comprend les étapes suivantes : le premier dispositif portable détecte au moins un deuxième dispositif portable ; une partie du document électronique est associée à chaque dispositif portable détecté ; on transfère à chaque dispositif portable détecté des données d'affichage représentatives de la partie qui lui est associée en vue d'un affichage ultérieur de ladite partie associée ; et une autre partie du fichier électronique distincte de toutes les autres parties associées est affichée.
