| 2026 | Embodied AI in the Wild: Comparing Older Adults' Interactions with an Avatar and a Humanoid Robot in a Public SpaceabstractAlthough embodied AI systems are increasingly developed and tested in public environments, their influence on the design of products for older adults remains underexplored. We examine how different types of embodiment, or form factor, shape initial encounters between humans and AI when conversational abilities are comparable. Building on prior work, we conducted a two-day field study at a senior citizens’ fair in Germany (n = 25, age 24–90), where participants interacted with the screen-based avatar Ann-Sophie and the humanoid robot Ameca. Both used LLM-based dialogue systems, enabling a focus on embodied interaction rather than linguistic performance. Qualitative results show contrasting affective and social responses: Ameca’s physical presence and gaze dynamics were described as both fascinating and unsettling, while Ann-Sophie was perceived as warm but socially limited. These findings highlight the role of embodiment in shaping comfort, expectations, and ethical awareness in public human–AI interaction. Eva Theresa Jahn, Ashita Ashok, Mea-Sophie Edelmann, Nora A. L.

| 2022 | Care Workers Making Use of Robots: Results of a Three-Month Study on Human-Robot Interaction within a Care HomeabstractResearch on social robots in care has often focused on either the care recipients or the technology itself, neglecting the care workers who, in and through their collaborative and coordinative practices, will need to work with the robots. To better understand these interactions with a social robot (Pepper), we undertook a 3 month long-term study within a care home to gain empirical insights into the way the robot was used. We observed how care workers learned to use the device, applied it to their daily work life, and encountered obstacles. Our findings show that the care workers used the robot regularly (1:07 hours/day) mostly in one-to-one interactions with residents. While the robot had a limited effect on reducing the workload of care workers, it had other positive effects, demonstrating the potential to enhance the quality of care.

| 2022 | Empowering Well-Being Through Conversational Coaching for Active and Healthy AgeingabstractAbstract With life expectancy growing rapidly over the past century, societies are being increasingly faced with a need to find smart living solutions for elderly care and active ageing. The e-VITA project, which is a joint European (H2020) and Japanese (MIC) funded project, is based on an innovative approach to virtual coaching that addresses the crucial domains of active and healthy ageing. In this paper we describe the role of spoken dialogue technology in the project. Requirements for the virtual coach were elicited through a process of participatory design in workshops, focus groups, and living labs, and a number of use cases were identified for development using the open-source RASA framework. Knowledge Graphs are used as a shared representation within the system, enabling an integration of multimodal data, context, and domain knowledge. Michael F.

| 2021 | Notes of memories: Fostering social interaction, activity and reminiscence through an interactive music exergame developed for people with dementia and their caregiversabstractThis paper presents the outcomes of an exploratory study focused on the evaluation of an interactive music exergame for People with Dementia (PwD) and their caregivers. PwD tend to isolate themselves from the outside world, therefore carers need to develop strategies to maintain communication with them. Studies indicate that music–based activities provide an effective way to achieve social interaction with PwD. At the same time, physical activity plays a major role in dementia-related interventions because it can slow down progression and provide meaningful stimulation. Our developed interactive music game bounds these two concerns together; we evaluated the system afterwards regarding its individual and social impact and its integration into the daily routines of both PwD and their caregivers, focusing on its capacity to provide both enjoyment and relief from some of the effects of dementia. Qualitative data collected over 4 months confirmed the valuable impact of music-based interventions of PwD. Of particular note was how PwD used the game to improve or maintain their physical condition while recovering past memories and an interest in social interaction.

| 2020 | Exploring Human-Robot Interaction with the Elderly: Results from a Ten-Week Case Study in a Care HomeabstractAgeing societies and the associated pressure on the care systems are major drivers for new developments in socially assistive robotics. To understand better the real-world potential of robot-based assistance, we undertook a 10-week case study in a care home involving groups of residents, caregivers and managers as stakeholders. We identified both, enablers and barriers to the potential implementation of robot systems. The study employed the robot platform Pepper, which was deployed with a view to understanding better multi-domain interventions with a robot supporting physical activation, cognitive training and social facilitation. We employed the robot in a group setting in a care facility over the course of 10 weeks and 20 sessions, observing how stakeholders, including residents and caregivers, appropriated, adapted to, and perceived the robot. We also conducted interviews with 11 residents and caregivers. Our results indicate that the residents were positively engaged in the training sessions that were moderated by the robot. The study revealed that such humanoid robots can work in a care home but that there is a moderating person needed, that is in control of the robot.

| 2020 | Social Technology Appropriation in Dementia: Investigating the Role of Caregivers in Engaging People with Dementia with a Videogame-based Training SystemabstractThere has been increasing interest in designing for dementia in recent years. Empirical investigation is now needed of the long-term role of caregivers in appropriating ICTs into the complex daily life of people with dementia (PwD). We present here the outcomes of a 4-month evaluation of the individual, social and institutional impact of a videogame-based training system. The everyday behavior and interactions of 52 PwD and 25 caregivers was studied qualitatively, focusing on the role played by caregivers in integrating the system into daily routines. Our results indicate that the successful appropriation of ICT for PwD depends partly on the physical, cognitive and social benefits for PwD, but especially on the added value perceived by their social care-network. We discuss the need for design in dementia to develop more socially embedded innovations that can address the social actors involved and thus contribute to practical solutions for professional and private care.

| 2020 | Exploring influencing factors of technology use for active and healthy ageing support in older adultsabstractAim of this study is to investigate the influence of technological and social cognitive factors for the use of sensor-based technologies for active and healthy ageing (AHA) support by older adults. In a mixed methods approach, data was initially obtained from an online questionnaire completed by older health technology users and used in a regression analysis, where factors from the Technology Acceptance Model (TAM) and the Social Cognitive Theory (SCT) served as predictors for health technology use (HTU). Further, in-depth interviews were conducted with older adults to gain insights into technology use and physical activity behaviour of older adults. The regression analysis showed that the TAM and SCT factors accounted for a significant proportion of variance (39.5%) in HTU. Significant predictors of HTU were physical activity (.399**), social support (.287*), and expectations regarding individual health (.440*) and physical appearance (−.470**), indicating physical activity as mediator for HTU. The qualitative analysis indicated the conflation of technology support with social environments as key for physical activity behaviour in older adults. The findings indicate physical activity as a mediator in HTU by older adults and suggest that the consideration of social factors in health technology design may facilitate the uptake of AHA technologies.

| 2018 | Exploring the Potential of Exergames to affect the Social and Daily Life of People with Dementia and their CaregiversabstractThis paper presents the outcomes of an exploratory field study that examined the social impact of an ICT-based suite of exergames for people with dementia and their caregivers. Qualitative data was collected over a period of 8 months, during which time we studied the daily life of 14 people with dementia and their informal and professional caregivers. We focus on the experiential aspects of the system and examine its social impact when integrated into the daily routines of both people with dementia themselves and their professional and family caregivers. Our findings indicate that relatives were able to regain leisure time, whilst people with dementia were able to recapture certain aspects of their social and daily activities that might otherwise have been lost to them. Results suggest that the system enhanced social-interaction, invigorated relationships, and improved the empowerment of people with dementia and their caregivers to face daily challenges.

| 2018 | Video-game based Exergames for People with Dementia and Their CaregiversabstractDementia not only affects the cognitive capabilities, especially memory and orientation, but also physical capabilities, which are associated with a decrease of physical activities. Here, ICT can play a major role to improve health, quality of life and wellbeing in older adults suffering from dementia and related stakeholders, such as relatives, professional and informal caregivers. The aim of the presented system is to increase physical and cognitive capabilities of people with dementia and their caregivers to support them in daily life activities, reduce the strain of the caregivers and improve both their wellbeing.

| 2018 | Facilitating Collaboration and Social Experiences with Videogames in Dementia: Results and Implications from a Participatory Design StudyabstractNeed for care and accordingly the prevalence of dementia is increasing rapidly. Information and communication technologies (ICT) may have the potential to support collaboration and cooperation between people with dementia and their caregivers and thus promote independency, wellbeing and quality of life of involved parties. In this context, the authors investigated the potential of an ICT-based videogame system to generate and facilitate social experiences of people with dementia and their caregivers. 26 people with dementia and their caregivers participated in a 16 month participatory design study. Results suggest that collaboration and cooperation among involved parties increased by using the system. Further, the study revealed positive and negative social experiences triggered by the videogame based system. This article will report on these results and provide implications that may support researchers to design similar systems with the potential to increase collaboration and cooperation among people with dementia and their caregivers.
