    Accessible Screenshots for Blind and Visually Impaired People
    (Mensch und Computer 2018 - Tagungsband, 2018) Engel, Christin; Bornschein, Denise; Weber, Gerhard
    Training material to learn new applications mostly include screenshots to describe the structure of the application or to represent required interaction steps. Blind people have no access to such graphics which are needed to learn handling the application. However, screen reader users need adapted information to learn effective interaction strategies in GUI environments. We propose a concept to make screenshots accessible for blind screen reader users by mapping ui elements and states to HTML elements. Based on a pilot study with two blind people we find requirements that ended up in a tool that automates the generation of interactive, accessible screenshots.

    Customized Wake-Word Integration in ANC-Enabled Headphones: Enhancing Assistive Technology for Noise-Sensitive Employees in Office
    (Proceedings of Mensch und Computer 2024, 2024) Schmalfuß-Schwarz, Jan; Gollasch, David; Engel, Christin; Branig, Meinhardt; Weber, Gerhard
    This paper explores the personalization of wake words in Active Noise Cancelling (ANC) enabled headphones designed as assistive technology for noise-sensitive individuals. We focus on the incorporation and assessment of intended wake words, categorizing them based on fillers and first names. Given the language-dependent nature of this approach, our research primarily addresses the English language. We propose an evaluation mechanism to determine the efficacy of potential wake words, predicting their recognition accuracy and length. The study involves a comparative analysis between combinations of fillers and first names, aiming to identify the optimal pairing. We offer recommendations on the best-performing combinations, enhancing the reliability and user experience of ANC headphones as a supportive tool for noise-sensitive individuals. Our findings aim to provide a robust framework for developing highly responsive and personalized wake word systems, tailored to the unique needs of noise-sensitive individuals in office environments.

    Diversity Monitoring - Bedeutung und Chancen für die Informatik
    (Mensch und Computer 2018 - Tagungsband, 2018) Kopitz, Juliane; Leonhardt, Lieselotte; Branig, Meinhardt; Engel, Christin
    Gesellschaftliche Vielfalt ist ein zentrales Thema der Mensch-Computer-Interaktion und wird in Methoden wie dem User-Centered-Design adressiert. Die vorliegende Arbeit beschäftigt sich mit den Chancen, die sich aus einem informierten Diversity Management für die Fach-richtung Informatik ergeben. Darüber hinaus wird ein mögliches Vorgehen für ein Diversity Monitoring an Hochschulen vorgestellt, welches neben der Sensibilisierung der Beteiligten auch die Verbesserung der Studiensituation zum Ziel hat.

    Towards Accessible Charts for Blind and Partially Sighted People
    (Mensch und Computer 2017 - Tagungsband, 2017) Engel, Christin; Gollasch, David; Branig, Meinhardt; Weber, Gerhard
    Perception of charts is a challenging task for blind and visually impaired people. Nevertheless, charts are an important tool to analyse data. Appropriate output media are needed making data analysis more accessible. We propose a workflow and tooling requirements to integrate the generation of accessible charts. Towards getting there, we present our current prototypical state and specify further steps.

    Workshop on Designing Accessible Extended Reality: An Opportunity for People with Disabilities and Disorders
    (Mensch und Computer 2023 - Workshopband, 2023) Engel, Christin; Schmalfuß-Schwarz, Jan; Gollasch, David; Branig, Meinhardt; Dirks, Susanne; Weber, Gerhard
    Extended Reality (XR) technologies offer a wide range of innovative use cases and interaction concepts. On the one hand, they provide several possibilities to reduce barriers for people with specific physical or mental needs, e.g., through simulations, gamification, or training scenarios. Individuals with anxiety disorders, dementia, or autism spectrum disorder, for example, may also benefit. On the other hand, it is challenging to design accessible XR technologies for heterogeneous user groups. Therefore, the area of accessible XR as well as adaptation based on users' needs and contexts, is of high interest and has barely been researched yet. Participants of the workshop are encouraged to discuss both – the major challenges and opportunities in designing XR-based assistive technology for different target groups and scenarios, as well as the accessibility of XR technologies.
