    Care: A chatbot for dementia care
    (Mensch und Computer 2022 - Workshopband, 2022) Müller, Claudia; Paluch, Richard; Hasanat, ABM Ali
    In recent decades various digital artifacts have been integrated into our daily life. One such integration is chatbots or conversational agents like Siri and Alexa. Even though those devices are helping primarily in daily activities, they can potentially be used for medical and health care purposes. In our research, we tried to focus on the current trend of using conversational agents in daily life and potential ways of using those in the medical field. Primarily we focused on chatbot uses in dementia care. Within our work, we analyzed interviews from care facilities and referred to some other research articles to find potential ways of using chatbots in care facilities. As a prototype, we developed a chatbot that will act as a communication medium between caregivers and dementia patients. We also conducted an interview to explore further improvement areas of the chatbot.

    Collaborative Information Seeking in Professional Work-Settings: A Study of Equipment Utilization
    (Datenbank-Spektrum: Vol. 14, No. 1, 2014) Böhm, Thilo; Klas, Claus-Peter; Hemmje, Matthias
    In various work domains, the collaborative performance of a work-task by a team can lead to a shared information need required to fulfill this task. Many empirical studies identified collaborative information seeking and searching (IS&S) as everyday work patterns in order to solve a shared information need and to benefit from the diverse expertise and experience of the team members. This paper presents first empirical results in an ongoing research project: We report on a pilot user study that investigates the collaborative IS&S practices of three work groups in academic and industrial research facilities. The aim of the conducted pilot study was to capture the use of software technologies for realizing collaboration, information seeking and sharing in real-world work settings. We discuss resulting design implications as guideline for extending the ezDL (ezDL: Easy Access to Digital Libraries, www.ezdl.de) system towards supporting collaborative IS&S activities.

    Functional Workspace for One-Handed Tap and Swipe Microgestures
    (Mensch und Computer 2019 - Workshopband, 2019) Dewitz, Bastian; Steinicke, Frank; Geiger, Christian
    Single-hand microgestures are a promising interaction concept for ubiquitous and mobile interaction. Due to the technical difficulty of accurately tracking small movements of fingers that are exploited in this type of interface, most research in this field is currently aimed at providing a good foundation for the future application in the real word. One interaction concept of microgestures is one-handed tap and swipe interaction that resembles one-handed interaction with handheld devices like smartphones. In this paper, we present a small study that explores the possible functional workspace of one-handed interaction which describes the area on the palmar surface where tap- and swipe-interaction is possible. Additionally to thumb-to-finger interaction which has been investigated more often, we also considered other fingers. The results show, that thumb interaction with index, ring and middle finger is the most appropriate form of input but other input combinations are under circumstances worth consideration. However, there is a high deviation on which locations can be reached depending on the individual hand anatomy.

    Improving Search Time Performance for Locating Out-of-View Objects
    (Mensch und Computer 2019 - Tagungsband, 2019) Gruenefeld, Uwe; Prädel, Lars; Heuten, Wilko
    Locating virtual objects (e.g., holograms) in head-mounted Augmented Reality (AR) can be an exhausting and frustrating task. This is mostly due to the limited field of view of current AR devices, which amplify the problem of objects receding from view. In previous work, EyeSee360 was developed to address this problem by visualizing the locations of multiple out-of-view objects. However, on small field of view devices such as the Hololens, EyeSee360 adds a lot of visual clutter that may negatively affect user performance. In this work, we compare three variants of EyeSee360 with different levels of information (assistance) to evaluate in how far they add visual clutter and thereby negatively affect search time performance. Our results show that variants of EyeSee360 with less assistance result into faster search times.

    Potenziale von Chatbots für den innerbetrieblichen IT-Support
    (HMD Praxis der Wirtschaftsinformatik: Vol. 57, No. 1, 2020) Fiore, Dario; Thiel, Christian; Baldauf, Matthias
    Chatbots sind Software-Assistenten, mit denen in geschriebener Sprache interagiert werden kann. Die Fortschritte in der künstlichen Intelligenz und insbesondere in der Verarbeitung natürlicher Sprache haben der Technologie in den letzten Jahren einen Schub verliehen. Während diese im Kontakt mit Kunden bereits häufig anzutreffen sind, existieren wenige wissenschaftliche Studien zur innerbetrieblichen Anwendung von Chatbots. Diese Arbeit untersucht anhand eines funktionalen Prototyps mit Mitarbeitenden einer Bank und eines Krankenhauses in der Schweiz die Frage, inwiefern ein innerbetrieblicher Chatbot den IT Service Desk in relevanten Use Cases entlasten kann. Basierend auf den Erkenntnissen zur Benutzerfreundlichkeit und zur Eignung einzelner Anwendungsfälle kann auf die Nutzungsabsicht und somit eine tatsächliche Nutzung durch Mitarbeitende geschlossen werden. Für die Beurteilung des Entlastungspotenzials für den IT Services Desk durch innerbetriebliche Chatbots müssen allerdings Nutzen und Aufwände (z. B. für Entwicklung und Betrieb des Chatbots) abgewogen und unternehmensspezifisch beurteilt werden. Chatbots are software-based assistants which enable interaction using written language. Advances in artificial intelligence and especially in natural language processing have given a boost to the technology in recent years. While such bots are already commonly used for customer interactions, in-company applications and related scientific studies are rare. This work uses a functional prototype with employees of a bank and a hospital to investigate the question of how an in-company chatbot can relieve the IT service desk in relevant use cases. Based on the findings on user-friendliness and the suitability of individual use cases, the intention of use and thus the actual use by employees can be inferred. For the assessment of the potential of burden reduction of the IT services desk through internal chatbots, however, benefits and expenses (e.g., for the development and operation of the chatbots) must be weighed up and assessed on a company-specific basis.
