    A conversational virtual human as autonomous assistant for elderly and cognitively impaired users? Social acceptability and design considerations
    (INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Kramer, Marcel; Yaghoubzadeh, Ramin; Kopp, Stefan; Pitsch, Karola
    In this paper we explore how a conversational virtual human could be designed to be deployed as a socially acceptable autonomous assistive system for elderly and cognitively impaired users. In particular, we focus on a system's functionality in helping to maintain a well-structured daily life. We present initial findings from two types of studies: (1) Conducting interviews and focus groups considering users' attitudes and design considerations for assistance in maintaining well-structured daily routines and (2) analyzing interaction between the system and its users' while entering data into a calendar application. Analysis has revealed a set of design considerations for developing a socially acceptable system. Microanalytic investigation of one user's concrete interaction with a Wizard-of-Oz version of the system has shown that a cognitively impaired person is able - by himself and only through interacting with the system - to gain insights into the system's possibilities and limits and to mistrust the system's competencies once the system initiates a repair sequence.

    Fallstudien zur Alltagsrelevanz von Zeit- und Kalenderkonzepten
    (Mensch und Computer 2016 - Tagungsband, 2016) Cyra, Katharina; Amrhein, Antje; Pitsch, Karola
    Basierend auf zwei Fallstudien werden erste Ergebnisse zu alltäglichen Zeit- und Kalenderkonzepten beim Terminmanagement von Menschen mit Unterstützungsbedarf beschrieben. Ausgehend von einer Interaktionsstudie mit einem Embodied Conversational Agent (ECA), in dem die Diskrepanz zwischen den Zeitkategorien des technischen Systems und denen der Nutzer hervortritt, werden auf Basis ethno-graphischer Feldforschung anhand zweier Fallstudien von Menschen mit kognitiven Einschränkungen die im Alltag relevanten Zeitkategorien dargestellt. Die Daten bieten erste Ansätze zur Formulierung von Implikationen für das Design des technischen Assistenzsystems hinsichtlich Kalender-Design, Übersetzerfunktion und Integration in das menschliche Unterstützungsnetzwerk.

    Interacting with Robots and Virtual Agents? Robotic Systems in Situated Action and Social Encounters
    (Mensch und Computer 2019 - Workshopband, 2019) Pitsch, Karola
    Research in informatics and the engineering sciences strives to endow technical systems – like (humanoid) robots, embodied conversational agents, voice interfaces etc. – with abilities that should allow the systems to “interact with people in a natural, interpersonal manner” (Breazeal et al. 2016: 1935). While the evaluation of such technologies has a strong tradition in the fields of psychology and cognitive sciences investigating the robot’s/agent’s usability and the users’ perception and attitudes using questionnaires and quantitative measures, it remains unclear as how these results are related to the concrete interactional conduct of the robot/agent, how users spontaneously attempt to deal with such technologies, which resources they mobilize to coordinate their actions with those of the robot/agent, and how the artefact and its agency are constructed. This workshop aims at addressing these open questions in that it suggests an interactional and praxeological approach based on the micro-analysis of video-taped recordings of encounters between humans and robots and a research methodology based on Ethnography and Conversation Analysis. It brings together researchers from the humanities and social sciences who investigate the ways in which robotic systems feature in situated action and social encounters ‘in the wild’.

    Referential Practices for a Museum Guide Robot. Human-Robot-Interaction as a Methodological Tool to Investigate Multimodal Interaction
    (Mensch und Computer 2019 - Workshopband, 2019) Pitsch, Karola
    An autonomous robot system was equipped with basic means to monitor the users’ success/failure in following a robot’s verbal-gestural deictic reference to an object and – in case of problems – to provide additional help, i.e. to suggest a ‘repair’ action. A real-world field trial with the robot acting as museum guide constitutes the basis for analysis of the users’ reactions. This example is used to explore HRI as a tool to investigate multimodal interaction.
