In his work, Oinas-Kukkonen modified the general flow concept into a Web-specific construct:
“Webflow is an optimal perceived user experience which improves a web user’s orientation and navigational use, as well as vice versa, and which is predicted by balanced user skills and the feeling of the web to be enjoyably challenging, the feeling of being in control of web use, and the perceived ease of use and usefulness of the web”.
In this sense, Webflow determines user engagement and is affected by the ease of use and degree of navigation of the Web applications user interface[
