Contextualized preview of image map links

Previewing links in hypertext navigation helps reduce the cognitive overhead associated with deciding whether or not to follow a link. In this paper we introduce a new concept called Dual-Use of Image Space (DUIS) and we show how it is used provide preview information of image map links. In DUIS the pixels in the image space are used both as shading information as well as characters which can be read. This concept provides a mechanism for placing the text information related to images in context, that is, the text is placed within the corresponding objects. Prior to DUIS contextualized preview of links was only possible with text links. The following are the advantages of contextualized preview image map links: (1) Readers can benefit from both the text and the image without making visual saccades between the two. (2) The text does not obstruct the image as is the case in the existing techniques. (3) It is easy for the readers to associate the image and its corresponding image since the two are presented close to each other. The text in the image space may also contain links, and for this reason, it is possible to introduce multiple links for image maps.
