Underneath Your Clothes: A Social and Technological Perspective on Nudity in The Context of AAL Technology.

One promising way to tackle healthcare challenges due to demographic change lies in the development of user-tailored AAL technologies. Video-based AAL technologies have the potential to provide rich information - in particular about accidents such as falls. However, as visual AAL is designed to record some parts of daily life at home, privacy concerns may comprise recordings in unwanted appearances and especially while being nude. Here, collaborative research is necessary to enable the development of user-tailored (visual) AAL technologies taking into account future users' needs and concerns. This article presents an interdisciplinary collaboration investigating perceptions of nudity from a social perspective, and developing solutions on nudity detection from a technical perspective. Focusing on first empirical insights and a proposed methodology for level-based nudity detection, this article concludes with interdisciplinary learnings, derived guidelines, and implications for future collaborative research.
