    Designing VUIs for Social Assistance Robots for People with Dementia
    (Mensch und Computer 2021 - Tagungsband, 2021) Striegl, Julian; Gollasch, David; Loitsch, Claudia; Weber, Gerhard
    Elderly people and especially people with dementia often experience social isolation and need assistance while performing activities of daily living. We investigate a novel approach to cope with this problem by integrating voice assistants and social assistance robots. Due to the special communication needs of people with mild cognitive impairment, the design of interfaces of such systems is to be based on the particular requirements of the target user group. This paper investigates, how a voice user interface should be designed for elderly users with mild cognitive impairment – such as an early stage of dementia – to provide personalised support throughout activities of daily living. A context and user analysis delivered a set of 11 guidelines for voice user interfaces for people with dementia. For a pilot study we selected those strategies often applied by caregivers in their communication with people with dementia and evaluated the voice user interface among elderly participants and healthcare workers who reported a high feasibility, usefulness and acceptance of the designed system.

    Teilautomatisiertes Fahren via Sprachsteuerung: Erwartungen und Anforderungen
    (Mensch und Computer 2018 - Workshopband, 2018) Detjen, Henrik; Geisler, Stefan; Salini, Maurizio; Wozniak, Martin; Borgmann, Colja
    Durch den technischen Fortschritt in der Spracherkennung und -verarbeitung wird Sprache als Interaktionsform auch in Fahrzeugen, z.B. zur Bedienung von Infotainmentsystem, immer populärer. Die Steuerung von teilautomatisierten Fahrzeugen über Sprache ist bisher wenig erforscht. Ziel dieser Arbeit ist es unter der grundsätzlichen Annahme der Eignung von Sprachsteuerung für teilautonome Fahrzeuge, Nut-zererwartungen und spezielle Anforderungen an eine Sprachsteuerung für die grundlegenden Fahrmanöver zu identifizieren. Aus den Ergebnissen eines Expertenworkshops und einer explorativen Videostudie werden Anforderungen und Sprachkommandos abgeleitet.

    What the user’s voice tells us about UX - Analysing parameters of the voice as indicators of the User Experience of the usage of intelligent voice assistants
    (Mensch und Computer 2020 - Workshopband, 2020) Obremski, David; Wienrich, Carolin; Carolus, Astrid
    This paper investigates voice parameters as indicators of the user experience during their interaction with voice-based technology. Following the requirements of a non-intrusive measurement and an automatic analysis, a tool is developed, which automatically measures and analyses speech recordings of users during interactions with voice assistants. The tool distinguishes between user- and voice assistant speech and analyses mean amplitude and pitch of user's speech as parameters reflecting the user experience of users. A user study presents first steps of a validation of the first version and reveals limitations and requirements for further developments.
