Have you ever felt lost in a foreign city? Software engineers know that feeling when they navigate through unfamiliar code. It might sound like a trivial problem, but studies have shown that they spend about 25% of their time just on code navigation. We – a group of researchers from the University of Stuttgart Visualization Research Center (VISUS) – have developed signposts for software engineers. Just like real signpost, ours intend to guide software developers through the code, providing data to make informed decisions where to turn next.
