    Accessible Automated Automotive Workshop Series (A3WS): Focus External Human-Machine Interfaces (eHMIs)
    (Mensch und Computer 2022 - Workshopband, 2022) Haimerl, Mathias; Colley, Mark; Löcken, Andreas; Riener, Andreas
    With modernizing traffic, a rise of automated vehicles (AVs) is expected. As AVs potentially need to communicate their intentions, external human-machine interfaces (eHMIs) seem to be an appropriate solution. While automotive research progresses quickly, people with special needs (PSN) are vastly underrepresented. With an aging population due to demographic changes and advances in medical treatments and with the stride towards equality and accessibility, the needs of these groups also have to be considered in the automotive domain. We provide an inclusive platform for interdisciplinary exchange on current and future topics, especially for academia, industry, and politics. This enables different perspectives with particular (but not exclusive) regard to user experience (UX) and psychology, product design, legislative concerns and, thus, support the communication and potentially founding of new topic streams. The aim is to create new interdisciplinary networks and collaborations to make future developments on vehicle-to-human (V2H) communication more inclusive.

    An Accessible User Interface Concept for Non-Verbal and Spatial Aspects of Business Meetings for Blind and Visually Impaired People
    (Mensch und Computer 2021 - Tagungsband, 2021) Koutny, Reinhard
    Business meetings are an integral part ofwork life. While the modus operandi has changed over the course of the past years and decades, shifting from meetings with analog tools like flipcharts to digital aids like projectors or large touch displays mounted to walls, some aspects have stayed the same: Information does not only get exchanged verbally. Visual information like flipcharts but also non-verbal communication and spatial information are deemed essential information. This information is basically inaccessibly to blind and visually impaired people, which renders business meetings inaccessible to them as well. Consequentially, BVIPs have a tremendous disadvantage in their professional life. While research has been concerned with the mitigation of single aspects of the whole problem, especially with tracking all types of information, no comprehensive and user-friendly user interface approach has been developed. This paper proposes an accessible user interface approach facilitating affordable off-the-shelf hardware, which allows access to visual, non-verbal and spatial aspects of business meetings in a user-friendly manner and presents a fully functional prototype called MAPVI brainstorming tool.

    AmI-VR: An Accessible Building Information System as Case Study Towards the Applicability of Ambient Intelligence in Virtual Reality
    (Mensch und Computer 2021 - Tagungsband, 2021) Götzelmann, Timo; Kreimeier, Julian; Schwabl, Johannes; Karg, Pascal; Oumard, Christina; Büttner, Florian
    Ambient intelligence represents a paradigm in which the user does not react to the environment, but vice versa. Accordingly, smart environments can react to the presence and activities of users and support them unobtrusively from the background. Especially in the context of accessibility, this offers great potential that has so far only been demonstrated for individual user groups. To overcome this limitation, we propose the automated, user- and context-related adaptation of the modality as well as locality of the representation of building information in the form of both an adjustable table as well as two displays on the basis of a prototype for a library information center. For being independent from material and regulatory restrictions and for better planability (especially with the ongoing COVID-19 pandemic) we used in addition to the hardware components also a Virtual Reality simulation, which proved to be very useful. Further optimization and evaluation will be needed for a more in depth understanding and dissemination in the long run, yet our prototype aims to help fostering further activities in the field of ambient intelligence, accessibility and virtual reality as a planning tool.

    Creating Accessibility 2.0 with Artificial Intelligence
    (Mensch und Computer 2023 - Tagungsband, 2023) Kubullek, Ann-Kathrin; Dogangün, Aysegül
    Despite the fact that artificial intelligence (AI) has existed for many years, for the first time it managed to attract the attention of the mainstream media. Since the release of the chatbot system "ChatGPT" by OpenAI in November 2022 the hype and interest in AI has increased significantly, not only in research but also among the general public. As a result, the question arises which specific application areas and target groups can benefit from artificial intelligence in the future. This article provides an overview of the use of artificial intelligence in creating accessibility. For this purpose, various aspects are considered on how AI technologies can contribute to removing barriers for people with disabilities and enable them to participate equally in social life. The aim of this paper is to highlight the potentials and challenges of uniting AI and accessibility. It discusses the contribution that artificial intelligence can make to closing the gap between technology and accessibility. Finally, a concept idea for the creation of a new kind of accessibility, the so-called Accessibility 2.0, is proposed.

    Dynamic indoor navigation and orientation system for people with impairments
    (Mensch und Computer 2020 - Tagungsband, 2020) Richter, Julia; Lorenz, Jeanine; Costantino, Maria; Traubinger, Verena; Tauchmann, Nico; Graichen, Thomas; Heinkel, Ulrich
    Assistive technologies play an important role on the way to an inclusive society. At this point, mobile indoor navigation for persons with impairments is a task far from being solved. Existing studies mainly focus on outdoor navigation, are closed source and closed data or are aimed at one single target group only, and consequently represent isolated solutions. Therefore, this study reports a design for an indoor navigation system for persons with different impairments, following the idea of open source and open data to facilitate a long-term and sustainable solution everyone can contribute to. The proposed system components are discussed, which include novel indoor mapping methodologies, user profile-specific indoor extensions for routing, navigation instructions and rendering, as well as an accurate technology for indoor positioning. Both modularity of the proposed system as well as the design-for-all approach allow, for the first time, the general application of mobile navigation addressing a variety of impairments.

    Reflecting on a Smart City Project for Older Adults
    (Mensch und Computer 2024 - Workshopband, 2024) Fietkau, Julian; Stojko, Laura
    Between 2015 and 2020 we participated in a joint research project to explore technological interventions fostering participation of older adults in urban spaces. UrbanLife+ involved multi-year qualitative and quantitative empirical work on obstacles faced by people aged 65 and up living in cities. This brief retrospective does not recap the previously published results of the project, but summarizes methodological and organizational insights as well as pragmatic experiences gathered during its runtime that have not yet been discussed publicly. We focus on aspects relevant for future urban technology projects aiming for accessibility and inclusivity. These include issues navigating interdisciplinary design teams, conducting questionnaire studies with older adults, maintaining participatory design principles with geographically distributed teams, and conducting empirical evaluations during the COVID-19 pandemic.

    Richtlinien zur barrierefreien Gestaltung virtueller Klassenzimmer für Blinde / Guidelines for the Accessible Design of Virtual Classrooms for the Blind
    (i-com: Vol. 13, No. 3, 2014) Köhlmann, Wiebke
    E-Learning kann den Zugang zu Lernmaterialien für Lernende mit Behinderung erleichtern. Jedoch treten insbesondere für blinde Nutzer Barrieren bei der Verwendung visuell dominierter synchroner Lernarrangements auf. Die vorhandenen barrierefreiheitsfördernden Funktionen erleichtern die Teilnahme blinder Nutzer, können jedoch eine gleichberechtigte Verwendung nicht garantieren. Dieser Artikel fasst eine Produktanalyse virtueller Klassenzimmer zusammen und stellt einen funktionalen Katalog mit Richtlinien an für blinde Nutzer zugängliche virtuelle Klassenzimmer vor.

    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.

    Usability und Barrierefreiheit – Gemeinsam sind wir stark?
    (Tagungsband UP05, 2005) Zimmermann, Gottfried
    Usability und Barrierefreiheit werden häufig als unabhängige, wenn auch verwandte Disziplinen betrachtet. Diese Sichtweise spiegelt sich in der Praxis wider, in der Maßnahmen zur Verbesserung der Usability und Maßnahmen zur Herstellung von Barrierefreiheit meist voneinander getrennt durchgeführt werden. Dieser Beitrag betrachtet Usability und Barrierefreiheit aus einer grundsätzlichen Sichtweise. Anhand von Prinzipien der Usability und Prinzipien der Barrierefreiheit werden Gemeinsamkeiten und Besonderheiten deutlich gemacht. Der Beitrag schließt mit einigen Anregungen zur Diskussion, die zu einer integrierten Betrachtungsweise der beiden Disziplinen führen sollen.

    Using wrist vibrations to guide hand movement and whole body navigation
    (i-com: Vol. 13, No. 3, 2014) Brock, Anke; Kammoun, Slim; Macé, Marc; Jouffrais, Christophe
    In the absence of vision, mobility and orientation are challenging. Audio and tactile feedback can be used to guide visually impaired people. In this paper, we present two complementary studies on the use of vibrational cues for hand guidance during the exploration of itineraries on a map, and whole body-guidance in a virtual environment. Concretely, we designed wearable Arduino bracelets integrating a vibratory motor producing multiple patterns of pulses. In a first study, this bracelet was used for guiding the hand along unknown routes on an interactive tactile map. A wizard-of-Oz study with six blindfolded participants showed that tactons, vibrational patterns, may be more efficient than audio cues for indicating directions. In a second study, this bracelet was used by blindfolded participants to navigate in a virtual environment. The results presented here show that it is possible to significantly decrease travel distance with vibrational cues. To sum up, these preliminary but complementary studies suggest the interest of vibrational feedback in assistive technology for mobility and orientation for blind people.
