This thesis is focused on the evaluation of interactive systems. It aims to contribute to the extension and equipment of the Cognitive Walkthrough method. This method is the subject of many studies and experiments worldwide. It has also undergone several modifications and extensions. Despite the interest in the method, its use poses many methodological and applicative problems. Firstly, this thesis describes the key elements related to human factors consideration in interactive system design and evaluation. Then, it proposes a state of the art on the evaluation of interactive systems based on the Cognitive Walkthrough method. Then the specification of an environment to support the inspection of interactive systems based on Cognitive Walkthrough is described. A mockup of an environment called CWE ("Cognitive Walkthrough Environment") is proposed; a first evaluation is exposed. A conclusion and perspectives end the thesis.
