Visual Ambient Assisted Living (AAL) technologies represent a promising approach to tackle these challenges by detecting emergency situations, such as falls, abnormal behavior, and helplessness. Beyond this potential and possible advantages, the use of visual AAL technology is closely connected with concerns regarding privacy and data security. So far, privacy perceptions and requirements have neither been specifically nor quantitatively investigated regarding the usage of visual AAL technology. Therefore, this study (<jats:italic>N<\/jats:italic>\u2009=\u2009139) applied an online survey and aimed at an investigation of (1) potential differences between human and technological invasions of privacy based on affective evaluations and perceived concerns, (2) activities being (not) allowed to be visually recorded in different contexts, and (3) selections of specific visual AAL technologies in different contexts. The results identified significant differences in the affective evaluation of human and technological privacy invasions as well as specifically perceived privacy concerns. Beyond that, the acceptance of visual recordings of activities depends on the context as well as on the sensitivity of the daily activities. The context also impacted the selection of specific visual AAL technology distinctly. The study enabled a first quantification of specific privacy perceptions, concerns, and requirements when visual AAL technology is used. The results are used to derive specific design and communication recommendations to address future users\u2019 privacy needs in the conceptualization, development, and design of visual AAL technology.<\/jats:p>","DOI":"10.1007\/s10209-023-01070-2","type":"journal-article","created":{"date-parts":[[2023,12,8]],"date-time":"2023-12-08T11:02:45Z","timestamp":1702033365000},"page":"503-515","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Somebody is watching me?
