Abstract

In this paper we present a task model for the usability monitoring environment called ErgoMonitor. ErgoMonitor realize an usability evaluation in websites through selective collection and analyses of the data from log files referring to the real interactions that are established between final users and an web interface. Nevertheless, the ErgoMonitor depends on the users expected behaviors previous identification and this activity is conducted by a specialist in usability that must observe the website characteristics or be assisted by traditional usability evaluation previous diagnosis to define which tasks (behaviors) should be inserted in the evaluation script. In this way, we developed a mechanism to register the expected users behaviors conceiving the Monitoring Tasks and Behaviors Model. This mechanism enabled the ErgoMonitor to realize web sites usability evaluations based on their log files.
