    Exit Violence: Comparing Usability of Physical and Visual Alarm Buttons in SOS App in the Context of Domestic Violence
    (Mensch und Computer 2023 - Workshopband, 2023) Sarkar, Nabanita; Marra, Konstantina; Osipova, Margarita
    This study investigated the effectiveness of SOS apps in supporting domestic violence victims, specifically examining the activation process through visual user interface (UI) and physical UI. Using a roleplay method and interviews, participant preferences and behaviours were assessed. Participants used an Android phone with an SOS app, activating it through either visual UI or physical UI. While participants displayed similar behaviours and visually focused on the screen for both methods, a strong preference for the physical UI was observed. Despite no significant behavioural differences, participants expressed higher satisfaction and perceived efficacy with the physical UI.

    Standardization of Forms in Governments
    (Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Scholta, Hendrik; Balta, Dian; Räckers, Michael; Becker, Jörg; Krcmar, Helmut
    Forms are central interfaces for information exchange between a government and its citizens. As a way to translate laws into practice, forms are an essential part facilitating this exchange. Unfortunately, forms often require substantial development effort to ensure they comply with legal requirements, with the result that citizens often describe them as highly complex. Standardization of forms through reference modeling would help to minimize governments’ effort by reusing elements and would reduce complexity for citizens by providing a unified representation of information. The article contributes a meta-model for a modeling language that can be used in representing reference models for forms. It follows a design science research approach to elicit form structure and editorial process requirements and to iteratively design the meta-model. The paper demonstrates and evaluates the meta-model using focus groups and application in three case studies. It extends research on standardization to reference modeling and government forms.
