Studies that provide evidence for the third hypothesis.

Study	Methodology	Evidence
Jaschinski et al [44]	Web-based survey (qualitative approach)	“Older adults’ privacy concerns were secondary to the perceived benefits of AAL [Ambient Assisted Living] in terms of health, safety and independence.”
Gettel et al [28]	Scoping review	“One study highlighted that older adults were concerned about privacy, but other studies found that privacy was not a barrier to AAL [Ambient Assisted Living] technology adoption.”
Chung et al [45]	Survey (qualitative approach)	“The proportion for the privacy concern increased slightly, though not statistically significant, indicating that participants were not bothered by the existence of the device at home.”
Fruchter and Liccardi [46]	Web-based review	“While we found that privacy and security related issues are present within our corpus, our results suggest these topics related to home assistants are rarely voiced, or openly reported by consumers in their online reviews. We can conclude that, for the most part, consumers who review home assistants tend to not discuss privacy or security concerns.”
Piau et al [47]	Web-based survey (qualitative approach)	“Less than a third were concerned about privacy breaches when using these technologies.”
Tan et al [48]	Semistructured interviews (qualitative approach)	“When asked about potential privacy or security concerns, our analysis of participant responses surfaced 6 types of reactions that may explain why they expressed little concern with privacy and security.”
Schomakers and Ziefle [49]	Questionnaire (quantitative approach)	“Our data suggests that privacy concerns are outweighed by security-related benefits in the acceptance decisions, as long as certain lines are not crossed—the unacceptable and must-have characteristics.”
