Loneliness has a direct impact on mental and physical health. This is especially relevant to older adults. In prior studies, socially isolated older adults wanted technology that would help them feel more physically present even across distances, such as telepresence robots. However, how useful this technology can be directly depends on whether people accept it over the long term. In this paper, we describe a case study in which we introduced telepresence robots into homes of older adults for seven months. We investigate how older adults’ progression through acceptance phases ebbed and flowed. We describe primary factors that affected speed of progression through acceptance phases: solving problems with technology, life situations (business vs. routines), and personality. We introduce example personas based on this case study. We also propose changes to the longitudinal technology-acceptance framework to take this more nuanced view into account. These outcomes will help future researchers and practitioners to better understand and influence longitudinal technology acceptance.
