    How WEIRD is CHI?
    (Association for Computing Machinery, 2021) Linxen, Sebastian; Sturm, Christian; Brühlmann, Florian; Cassau, Vincent; Opwis, Klaus; Reinecke, Katharina [in: CHI '21. Proceedings of the 2021 CHI Conference on Human Factors in Computing Systems]
    Computer technology is often designed in technology hubs in Western countries, invariably making it “WEIRD”, because it is based on the intuition, knowledge, and values of people who are Western, Educated, Industrialized, Rich, and Democratic. Developing technology that is universally useful and engaging requires knowledge about members of WEIRD and non-WEIRD societies alike. In other words, it requires us, the CHI community, to generate this knowledge by studying representative participant samples. To fnd out to what extent CHI participant samples are from Western societies, we analyzed papers published in the CHI proceedings between 2016-2020. Our fndings show that 73% of CHI study fndings are based on Western participant samples, representing less than 12% of the world’s population. Furthermore, we show that most participant samples at CHI tend to come from industrialized, rich, and democratic countries with generally highly educated populations. Encouragingly, recent years have seen a slight increase in non-Western samples and those that include several countries. We discuss suggestions for further broadening the international representation of CHI participant samples.

    Is It Still Where I Expect It?—Users’ Current Expectations of Interface Elements on the Most Frequent Types of Websites
    (Oxford University Press, 27.08.2016) Heinz, Silvia; Linxen, Sebastian; Tuch, Alexandre Nicolas; Frasseck, Lars; Opwis, Klaus [in: Interacting with Computers]
    Knowing users’ expectations about what they expect on a website and where they expect to find it is crucial for the success of a website. For the last decade, technological advances have entailed major changes in website design but the impact of these changes on users’ mental representations of websites remains unclear. In an online study (N = 841), we asked users to sketch their prototypical version of an online shop, a news website and a company page, thereby indicating the interface elements they expect on the website and their expected location. We compared our results to those of a previous study to investigate changes in users’ mental representations of websites over time. This comparison suggests that interface elements such as the logo, main content and navigation area are still expected in the same location although others have shifted to the rich footer area at the bottom of the website. In addition, new elements such as links to social networks have been incorporated into users’ mental representations whereas other interface elements have disappeared. By providing updated consolidated blueprint models for all three website types, we help designers to create expectation-based websites. Further implications for research and practitioners are discussed.

    Mental Models for Web Objects in Different Cultural Settings
    (ACM, 2014) Linxen, Sebastian; Heinz, Silvia; Müller, Livia; Tuch, Alexandre Nicolas; Opwis, Klaus [in: CHI '14 Extended Abstracts on Human Factors in Computing Systems]
    "Know your users!" A short request but a challenging one. Studies have shown that the positioning of web objects according to the users' mental models can prevent errors and increase the efficiency of interaction. Therefore an important aspect of the design of websites is to take the expectations of the users into account. However the results of these studies are based on research with limited target groups and neglected to consider cultural aspects. To approach this issue the currently being conducted study aims primarily to (1) identify and visualize mental models for different websites types for different countries, (2) highlight differences and similarities in the mental models of the subjects based on their nationality and (3) show the influence of experience with international websites on the mental models of the user. The results gained will be helpful during the design and localization process for international target groups.
