Shopping Website Accessibility Study Based on Users Mental Models. The arrival of the Internet information age promotes the development of electronic and information platform  website. A website is a provider of information and a platform for users to communicate and interact. Website interface design must consider human cognitive factors, emotional factors, so the website interface design and interaction design is particularly important. Through experimental demonstration and research, this paper takes shopping website as the research object to analyze the mental model of users in website interface design and the influence of different usersxe2x80x99 occupations on the mental model. According to the conclusion of the analysis, firstly, the change process of user mental model in interface interaction is proposed. Secondly, based on the user mental model, this paper summarizes the design principles of the website. Finally, this paper provides a new way of thinking for the study of website accessibility.

Analyzing Studentsxe2x80x99 Mental Models of Technical Systems Successful innovation processes require communication between different disciplines, such as mechanical and electrical engineering or software development. However, such communication is hampered by differences in individual mental models. This paper presents two studies that investigate mental models of engineering students. The studies apply SART and card sorting to analyze mental models and were conducted at the beginning of their academic education to understand influences on disciplinespecific mental models that are observed in practice. The studies indicate that mental models of engineering students are typically based on structural properties of the machines. A second study identified nine dimensions that classify mental models of students. Future work that facilitates the analysis of mental models on a larger scale is proposed. The aim of this work is to understand these differences and inform educational mechanisms that teach mental model flexibility and perspective change.
