    Autonomous Driving and the Elderly: Perceived Risks and Benefits
    (Mensch und Computer 2018 - Workshopband, 2018) Schmargendorf, Maike; Schuller, Hans-Martin; Böhm, Patricia; Isemann, Daniel; Wolff, Christian
    Autonomous driving offers possibilities to simplify and enhance the lives of many people. One group that could benefit a lot from autonomous driving is elderly people. In this contribution, we examine the opportunities and risks that elderly people see in autonomous driving. This was done by conducting semi-structured interviews with 10 participants which offered some insight into the acceptance of autonomous driving among elderly people. The identified perceived benefits and risks are validated by an online survey in which 113 people from 59 to 90 years of age have taken part. In general, elderly people are not rejecting the idea of using autonomous driving altogether. They see benefits in increased mobility and therefore greater independence at a higher age as it allows disabled people to regain lost mobility. However, our study also revealed privacy and security concerns, factors known to have a negative impact on technology adoption.

    Comparing Smartwatch Input Modalities for Older Users in a TVControl Scenario
    (Mensch und Computer 2017 - Workshopband, 2017) Roberts, Jonas; Wölfl, Johannes; Märkl, Christoph; Böhm, Patricia; Isemann, Daniel
    Older people have been hesitant to accept smartwatches as supporting devices in their daily routine. We present a study which used an environment familiar to many older users to examine differences between touch and voice input for smartwatches. As people get older they tend to spend considerable amounts of time watching television. In this familiar setup we examined to what extent touch and voice input differ, using a smartwatch as a television remote control. We developed two smartwatch applications, one for each input modality, with which users could operate a TV simulator. In pre-tests, we determined possible speech input commands and preferred smartwatch gestures. Testing with eight older adults we found potential for both input modalities with speech input taking significantly longer. Although a majority of participants reported speech to be "easier" (with the rest undecided), participants were ultimately divided in their preference of one system over the other.

    Golden Oldies and Silver Surfers 2.0: 2. Workshop zum alters-differenzierten User Experience Design
    (Mensch und Computer 2018 - Workshopband, 2018) Böhm, Victoria; Böhm, Patricia; Schlögl, Stephan; Isemann, Daniel
    Die Berücksichtigung von Nutzer-Diversität bei der Technologieverwendung ist in den letzten Jahren stark in den Fokus der Forschung im Bereich Human-Computer Interaction gerückt. Unter Verwendung verschiedener Schlagwörter wie beispielsweise Digitale Partizipation, Inklusion, Design for Diversity, und Accessibility werden Ansätze entwickelt, welche digitale Systeme und deren Entwicklung so gestalten, dass sie der Heterogenität des Menschen gerecht werden. Der vorgeschlagene Workshop greift hier das Alter der Nutzer als einen der relevanten Aspekte für die Untersuchung und Gestaltung einer differenzierten Mensch-Computer-Interaktion heraus.

    Golden Oldies and Silver Surfers: User Experience Design für eine ältere Zielgruppe
    (Mensch und Computer 2017 - Workshopband, 2017) Böhm, Victoria; Böhm, Patricia; Isemann, Daniel
    Die „Generation 50+“ stellt aufgrund körperlicher Veränderungen, verändertem Nutzungskontext sowie ihrer heterogenen Vorerfahrung mit digitalen Anwendungen besondere Ansprüche an User Interfaces und User-Centered Design Methoden. Daher sollen im geplanten Workshop Herausforderungen und Lösungsansätze zur Adaption von Usability-Engineering Methoden und User Interfaces sowie Erfahrungen aus Praxisprojekten diskutiert werden.

    Modelling creative influence between artists and their works with OWL and CIDOC CRM
    (INFORMATIK 2017, 2017) Tran, Tuan Anh; Isemann, Daniel
    In this paper we present an ontology for modelling creative influence between artists as documented as part of an international art exhibition on Dutch Golden Age genre painters titled Vermeer and the Masters of Genre Painting: Inspiration and Rivalry. The model, which describes influences on an artwork-to-artwork level, was developed in close cooperation with the curatorial advisory board of the exhibition and has guided the data gathering efforts in preparation for the exhibition. Our ontology extends the CIDOC Conceptual Reference Model (CRM) and has been influenced in its design by the CRM. It was implemented using the Erlangen CRM implementation and populated with an RDF graph containing over 900 instances of individual connections between works of art, referencing external Linked Open Data from Getty ULAN. The focus of this paper is on technical questions of knowledge modelling and implementation. The wider project context, the genesis of the domain expert conceptualizations and use cases for the ontology and RDF data are presented elsewhere in greater detail.

    A Qualitative Interview Study on Older Adults’ Attitudes Towards Social Networking Sites
    (Mensch und Computer 2017 - Tagungsband, 2017) Sippl, Colin; Imminger, Benedikt; Geissel, Ricardo; Böhm, Patricia; Isemann, Daniel
    We present a qualitative interview study on older adults attitudes towards social networking sites (SNSs), in particular on reasons that keep them from using SNSs or entice them to do so. In cooperation with a multigenerational house in Bavaria (Ger.: Mehrgenerationenhaus, abbr. MGH), we conducted eight semi-structured interviews with older adults (50+) who were involved in computer tuition at the MGH. We recruited two different participant groups: 1. tutors, older adults with advanced computer skills who give free computer lessons and 2. tutees, participants of said lessons with relatively fewer computer skills. Although our sample included dedicated Facebook users, we found prejudices towards SNSs to be prevalent among our interviewees. Our findings indicate that security concerns and a lack of knowledge play a big part in keeping participants from using SNSs. Among the reasons fielded for SNS use were particular forms of participation and social interaction, but also pastimes and hobbies. Though more of the tutors are using SNSs, we could not find stark differences in attitudes towards SNS usage between tutors and tutees.
