Principles of usability in human-computer interaction driven by an evaluation framework of user actions

Abstract

This paper tries to address problems that come out when designing a web page and how these problems affect people who use it. We will try to find the way to make our web pages easy to use and to give our user as little obstacles in his efforts as possible. He has to feel that every time he comes back to our web site, everything is on places where it should be and that everything acts as it should. One could say he has to see that everything looks normal. In this paper our aim will be to address web users, their needs and ways to improve their overall efficiency with achieving their tasks. We go through all main parts of usability issues according HCI as well as the current state of the art based on the most cited or specialised literature. In second part we introduce a development of a software platform that will sends user clicks to the server and allows us to go through these data in the web application for administrators. Design and development of this framework along with concrete computation of websites evolution index is also presented.
