ABSTRACT
Socially Assistive Robots (SARs) are expected to support autonomy, aging in place, and wellbeing in later life.
Acceptance and successful assimilation of SARs among older adults depend ontheir Quality Evaluations (QEs),
namely, the pragmatic and hedonic evaluations and overall attractiveness. Previous studies showed that trust in
robots signifcantly enhances QE, while technophobia considerably decreases it. However, so far, these key
factors have always been explored separately. Applying a case study approach, the current research aimed to
examine the relative impact of these two factors on older persons’ QE of SARs. The study was based on an online
survey of 384 individuals aged 65 and above. Respondents were presented with a video of Gymmy, a robotic
system for physical and cognitive training, and flled out a questionnaire relating to that system. The results
indicated a positive association between trust and QE and a negative association between technophobia and QE.
A simultaneous exploration demonstrated that the relative impact of technophobia was signifcantly more
substantial than that of trust. In addition, the pragmatic qualities of the robot were found to be more crucial to its
QE than the social aspects of use. The fndings suggest that implementing robotics technology in later life
strongly depends on reducing older adults’ technophobia regarding the convenience of using SARs. The study
also highlights the importance of simultaneous explorations of facilitators and inhibitors to SARs use.
1. Introduction
1.1. Problem description
Population aging is expected to be the most prominent global de-
mographic trend of the twenty-frst century, with repercussions for
nearly all sectors of society (Zafrani & Nimrod, 2019). Globally, the
population aged 65 or over is growing faster than all younger age groups
(Raja et al., 2021; Taieb-Maimon & Vaisman-Fairstein, 2022). To
address the social and economic challenges associated with aging (Yuan
et al., 2021) and the increased need for caregivers (Stuck & Rogers,
2018), smart technological solutions are necessary (Ghorayeb et al.,
2021), wherein social robots are expected to play a central role (Beer
et al., 2012).
In the past two decades, various robotic technologies have been
created particularly for older people or adapted to their needs (Krajnik
et al., 2015). A systematic review of the literature on Human-Robot
Interaction (HRI) in later life (Zafrani & Nimrod, 2019) indicated that
interacting with robots is experienced by older people as cognitively
stimulating (Louie & Nejat, 2020) and as an enjoyable activity (De Graaf
et al., 2015). It also decreases frustration and stress and has benefcial
effects on users’ psychological wellbeing (Henschel et al., 2021).
Overall, it was found to have numerous opportunities and great poten-
tial to improve older adults’ independence and autonomy leading to
improved quality of life (Robinson & Kavanagh, 2021; Wang et al.,
2021; Wu et al., 2021). Moreover, future robots are expected to play a
variety of roles such as caregivers (Amin et al., 2021), physical trainers
(Krakovsky et al., 2021), personal assistants (Jishnu et al., 2020),
teachers (Adamson et al., 2021), weight-loss coaches (Kidd & Breazeal,
2007) and even sexual objects (Jecker, 2021).
Socially Assistive Robots (SARs) combine features of assistive robots
and social robots. Assisting users through social rather than physical
interaction, SARs are designed to provide the appropriate emotional,
cognitive, and social cues to encourage individuals’ development,
learning, or therapy (Feil-Seifer & Mataric, 2005). Such robots are
offered in various formats: humanoids, non-humanoids, and androids
(Yogeeswaran et al., 2016). A humanoid robot is a robot with its body
shape is designed and built to resemble the human body (Cuevas et al.,
2021; Iivari, 2012), while non-humanoid robots, on the other hand, are
often more machine-like in appearance (Cha et al., 2018). An android
