    Digital Maternity Records: Motivation, Acceptance, Requirements, Usability and Prototype Evaluation of an Interface for Physicians and Midwives
    (Mensch und Computer 2021 - Tagungsband, 2021) Matthias W. Beckmann, Gradl
    Maternity records ("Mutterpass") are a central tool in Germany’s antenatal care. Its digitalisation offers advantages such as improved readability, data standardisation, analysability, digital assistance and the avoidance of media breaks. Despite the examined necessity and technical possibility, no system has been implemented yet. In this work, we address this gap by assessing physicians’ and midwives’ perception, motivation, acceptance and requirements of a digital maternity record and its user interface in particular. Nine medical professionals participated in semi-structured interviews. Based on the results, an interface prototype was subsequently developed. The prototype laid a particular focus on two different gravidogram implementations. Thirteen medical professionals participated in the interactive user interface study, which aimed to assess general acceptance, completion time, error rate and implemented assistance functions compared to the analogue counterpart. Results show that the implementation of the digital maternity logbook is of value and that its advantages are both accepted and demanded by medical professionals. Eight key requirements were identified. A tabular gravidogram prototype, inspired by the analogue maternity record, was favoured over a more novel list prototype. Users presented a clear learning curve of the digital system. Nevertheless, the digital average completion time is 30% higher than its analogue counterpart. The digital prototype lead to a lower average number of errors per entry (0.45±0.3 vs. 0.58±0.4). With respect to digital maternity records, this work underlines user acceptance, summarizes key user requirements and presents a first step on the path to a digital maternity record interface for medical professionals. On a broader scale, it delivers insights based on several metrics with respect to digitalisation in an area that is still highly dominated by long established paper-based tools.

    Emotions in the Age of Automated Driving - Developing Use Cases for Empathic Cars
    (Mensch und Computer 2019 - Workshopband, 2019) Oehl, Michael; Ihme, Klas; Bosch, Esther; Pape, Anna-Antonia; Vukelić, Mathias; Braun, Michael
    Improving user experience of highly automated vehicles is key to increase their acceptance. One possibility to realize this is the design of empathic cars that are capable of assessing the emotional state of vehicle occupants and react to it accordingly by providing tailored support. At the moment, the central challenge is to derive relevant use cases as basis for the design of future empathic cars. Therefore, we propose a workshop that aims to bring together researchers and practitioners interested in affective computing, affective interfaces and automated driving as forum for the development of a roadmap towards empathic vehicles using design thinking methods. During the workshop, we will gain a common understanding of the central concepts and listen to impulse talks about current and recent projects on emotions during automated driving. Based on this, relevant use cases are generated in group work and discussed with the goal to identify potential research and knowledge gaps. Finally, a road map for research towards the realization of automated empathic cars is formulated from the results.

    Let’s Chat Internal: User Acceptance of an In-Company Service Desk Chatbot
    (Mensch und Computer 2021 - Tagungsband, 2021) Stütz, Lena; Riener, Andreas
    Due to remote working models, which were strengthened by the COVID-19 pandemic, it became highly relevant to digitalize onsite service desk consultations. Virtual enterprise assistants which simplify the interaction with in-company services provide similar advantages to their popular peers in customer service: high availability and customer satisfaction, and low response time and costs. To find out how their usage affects user acceptance we developed an early high-fidelity prototype for an in-company UX service desk chatbot and evaluated it in an online survey (N=53) and user study (N=14) with employees from the industry using the Technology Acceptance Model. The results show that the prototype’s acceptance does not differ from the classical service and prior experiences with textual chatbots in a private usage context but was rated higher than a private sample bot.

    Trust in activity tracker measurement and its link to user acceptance
    (Mensch und Computer 2018 - Tagungsband, 2018) Trommler, Daniel; Attig, Christiane; Franke, Thomas
    Inaccuracies in data measurement can impair trustworthiness of activity trackers (i.e., wearable fitness devices) and, thus, constitute a usability challenge possibly impairing user acceptance. With the present research, we aim at advancing understanding of perceived trustworthiness of activity tracker measurement and its relevance for user acceptance. N = 79 users of activity trackers were surveyed regarding their daily interaction with the tracker, user experience, and user acceptance. Results indicated a substantial variance in perceived trustworthiness. Many users perceived suboptimal trustworthiness of the tracking of their activity data, indicating potential for optimization. Further, analyses showed that higher perceived trustworthiness of activity tracker measurement was indeed linked to higher user acceptance. The results highlight the potential of enhancing user acceptance of activity trackers by improving perceived trustworthiness of activity measurement.

    User acceptance of augmented reality glasses in comparison to other interaction methods for controlling a hand exoskeleton
    (Mensch und Computer 2019 - Workshopband, 2019) Ableitner, Tobias; Soekadar, Surjo; Schilling, Andreas; Strobbe, Christophe; Zimmermann, Gottfried
    Every year, several hundred thousand people suffer a stroke often leading to long-term motor disabilities that impair their quality of life. In this context, hemiplegia including paralysis of hand and fingers plays a key role, leaving stroke survivors unable to perform tasks requiring both hands. In case of lesions at the level of the brain stem or the spinal cord, paralysis can also affect both sides resulting in very severe constraints for performing most activities of daily living. A neural-guided hand exoskeleton can restore motor hand function after a stroke or spinal cord injury. However, controlling such hand exoskeleton raises several challenges related to human-machine interaction. While it should be operated without the user's hands and require as little physical and cognitive strain on them as possible, it should be also as inconspicuous as possible to avoid stigmatization of the users. To tackle these challenges, we conducted a survey among 62 healthy test persons to shed more light on the aspects of user acceptance regarding 12 input and 14 output methods, as well as 3 different application contexts. We found that there are differences in user acceptance for the various input and output methods between public contexts on the one hand and home and rehabilitation contexts on the other. In general, inconspicuous, handy and widely used devices are preferred in public. Also, we found that spectacle wearers are slightly more open to using AR glasses than non-spectacle wearers.
