adapt to the change leaving a deficiency somewhere else. Human Computer Interaction has a huge part in cognitive ergonomics because we are in a time period where most of life is digitalized. This created new problems and solutions. Studies show that most of the problems that happen are due to the digitalization of dynamic systems. With this it created a rise in the diversity in methods on how to process many streams of information. The changes in our socio-technical contexts adds to the stress of methods of visualization and analysis, along with the capabilities regarding cognitive perceptions by the user. Methods Successful ergonomic intervention in the area of cognitive tasks requires a thorough understanding not only of the demands of the work situation, but also of user strategies in performing cognitive tasks and of limitations in human cognition. In some cases, the artifacts or tools used to carry out a task may impose their own constraints and limitations (e.g., navigating through a large number of GUI screens). Tools may also co-determine the very nature of the task. In this sense, the analysis of cognitive tasks should examine both the interaction of users with their work setting and the user interaction with artifacts or tools; the latter is very important as modern artifacts (e.g., control panels, software, expert systems) become increasingly sophisticated. Emphasis lies on how to design human-machine interfaces and cognitive artifacts so that human performance is sustained in work environments where information may be unreliable, events may be difficult to predict, multiple simultaneous goals may be in conflict, and performance may be time-constrained. A proposed way of expanding a user's effectiveness with cognitive ergonomics is to expand the interdisciplinary connections related to normal dynamics. The method behind this is to transfer the pre-existing knowledge of the various mechanics in computers into structural patterns of cognitive space. This would work with human factors in developing an intellectual learning support system and applying an interdisciplinary methodology of training, helping the effective interaction between the person and the computer with the strengthening of critical thinking and intuition. Disability Accessibility is important in cognitive ergonomics because it is one pathway to build better user experience. The term accessibility refers to how people with disabilities access or benefits from a site, system, or application. Section 508 is the founding principle for accessibility . In the U.S., Section 508 of the Rehabilitation Act is one
