- a technique for adding a sticky note by designating an arbitrary part in a page is known (see, for example, Patent Document 1).
- a comment can be added to a sticky note added to a designated portion in a page according to Patent Document 1 and displayed. Therefore, there is a demand that the comment added in this way is shared among friends. In order to satisfy such a demand, a mechanism for sharing a comment added to a tag between a plurality of users has been proposed (see, for example, Patent Documents 2 and 3).
- an arbitrary portion in a page is specified using, for example, two-dimensional coordinates based on, for example, the upper left corner portion in the page (see page 12 of Patent Document 2). (See lines 34 to 41 and paragraphs 0021 to 0022 of Patent Document 3, respectively). For this reason, when a page with a tag attached to a designated part using two-dimensional coordinates is displayed on two terminals with different browsing environments, the page with the tag attached correctly to the designated part is displayed on one terminal. Is displayed on the other terminal, there is a possibility that a page with a sticky note is displayed in a different position from the designated part.

- the present invention has been made to solve the above-described problem, and even when the same element coexists in a page, the portion in the page can be specified uniquely and the display environment can be changed. Even in such a case, an object is to eliminate a situation in which the display position of the sticky note or the like is shifted with respect to the designated portion.
- the partial designation device instead of partial designation using relative coordinates that may cause a positional deviation of the display of a sticky note or the like when the display environment changes, a plurality of elements are included. Partial specification using index information indicating the order of the specified elements corresponding to the partial specification locations in is performed. That is, in the partial designation device according to the present invention, the relative coordinates relating to the partial designation location are converted into index information indicating the order of the designated elements corresponding to the partial designation location among a plurality of elements, and obtained by this conversion. The part of the page is specified using the index information.
- the partial designation device for example, when the same element coexists in the page, different index information is assigned to each element. Further, even if the relative coordinates related to the designated portion in the page change due to the change in the display environment, the order of the specific elements among the plurality of elements is not changed. For this reason, the index information indicating the order of the designated elements among the plurality of elements does not change.
- the designation within the page can be performed uniquely, and the designation can be performed even when the display environment changes. It is possible to eliminate a situation in which the display position of a sticky note or the like with respect to the portion is shifted.
