    Age-Related Differences in Preferences for Using Voice Assistants
    (Mensch und Computer 2021 - Tagungsband, 2021) Gollasch, David; Weber, Gerhard
    In the past fewyears, voice assistants have become broadly available in different forms of presentation and devices – not only as a personal assistant within smartphones but as smart speakers, within TV sets or as part of an in-car infotainment system. Furthermore, we live in an ageing society and considering elderly people as users of voice assistants gains more relevance driven by both trends. The goal of this study is to identify the specific age-related preferences of older people when using a conversational user interface in form of a voice assistant. We conducted a survey based on 26 elderlyrelated communication strategies among participants of different age. The participants had to evaluate the strategies according to their own preferences for using voice assistants. As a result, we identified 11 preferences specific to older users. Surprisingly, most of the communication strategies, when applied to voice assistants, seem to be relevant for users of all ages, and a few of the communication strategies do not apply when used in voice assistants. The preferences specific to older people help to develop new guidelines for voice user interfaces or conversational user interfaces in general. They do not automatically lead to those guidelines but provide a foundation to derive requirements, develop guidelines and evaluate those guidelines by means of user-based usability tests.

    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.
