Medical device manufacturers and other high-technology companies increasingly incorporate algorithmic data surveillance in next-generation medical wearables. These devices, including hearing aids, leverage patient data created through human-computer interaction to not only power devices but also increase corporate profits. Although data protection laws establish privacy requirements for personal information collection and use, these companies continue to use patients’ personal information with little notice or education, significantly curtailing the agency of wearers. We explore the complex ecology of the Starkey Halo smart hearing aid, focusing on the opacity of its algorithmic functionality and examining patient education materials for disclosures of data surveillance. We contextualize these findings within privacy law in the United States and European Union that are relevant to algorithmic surveillance and recommend specific steps to enhance wearer agency through informed decision-making.

Considering recent returns to pre-Aristotelian understandings of ethos as the creation of dwelling spaces, this article argues that dwelling in algorithmically mediated spaces such as Facebook is intrinsically connected to ethos. The 2016 Dueling Protests in Houston, Texas serve as a case study of how Facebook’s platform functioned as a crucial tool for the Russian Internet Agency’s (IRA) disinformation campaigns. Examining interactions in these ethe ecologies reveals how algorithms shape community perceptions and constructions of ethos.
