Hypertext links make it possible to navigate from page to page, to load several pages, to also build in the user's head a sort of temporary tree structure and, as far as possible, to offer a concrete navigation experience. This techno-semiotic change placed in favor of the single-page site therefore changes this experience into something linear, in which reading is done by scrolling. All these questions are addressed by Vivien Lloveria, teacher-researcher at Ce ReS – Center for Semiotic Research in Limoges, and are answered through her latest publication that I share with you below. The x-height of a font used for important cockpit documentation should not be less than 10 inches The aspect ratio of a font should be 5:3 The vertical spacing between lines should be no less than 25-33% of the overall font size.
Why did we move from hyperlink to single-page site? [ download PDF ] From a personal image manipulation service point of view, the single-page sites correspond for me to the evolution of uses and in particular touch screens as well as the consultation of the web on small supports such as smartphones. Thus, just as the pleasure of touch screens encourages us to scroll rather than click, we must also imagine that the original size of smartphones as well as their weak Internet connection (even if today this is very debatable) guide this choice of single-page website.
Vivien Lloveria's conclusions are very interesting since they describe the evolution of the technical and semiotic properties of Internet sites as well as a way of rethinking appearance metaphors knotted rope and star icons action metaphors walking, the breadcrumb, surfing but also to note a shift from the external vision that one would have of a website by abstraction and its complexity to the internal vision which generates a simplification of the information, sometimes to the extreme up to a certain impoverishment of the content. The horizontal spacing between characters should be 25% of the overall size. Avoid using long sentences in italics. Use mostly one or two typefaces. Use black type on a white background for most cockpit documents.
