Navigation is the least understood aspect of web accessibility for many web developers, but is the most important for providing users with disabilities equal access to the web. It seems that the ability of users with disabilities to navigate over the web is not dependent on the graphical complexity, but on the markup used to create the structure of the website. Therefore, it's necessary to design some software helpers to help all users to mark themselves in space during a session of navigation. It provides a map of visited sites, thus giving an explicit representation of virtual space. Various levels of visualization are set up to make the map more visible and less overloaded.
