GPTs are customized LLM apps built on OpenAI's large language model.Any individual or organization can use and create GPTs without needing programming skills.However, the rapid proliferation of over three million GPTs has raised signifcant privacy concerns.To explore the privacy perspectives of users and creators, we interviewed 23 GPT users with varying levels of creation experience.Our fndings reveal blurred lines between user and creator roles and their understanding of GPT data fows.Participants raised concerns about data handling during collection, processing, and dissemination, alongside the lack of privacy regulations.Creators also worried about loss of their proprietary knowledge.In response, participants adopted practices like self-censoring input, evaluating GPT actions, and minimizing usage traces.Focusing on the dual role of user-creators, we fnd that expertise and responsibility shape privacy perceptions.Based on these insights, we propose practical recommendations to improve data transparency and platform regulations.

The consequences of an aging society pose one of the major challenges of our time. Technology solutions that alleviate the strain on the overburdened healthcare system can effectively support individuals needing assistance. Still, technology acceptance is a crucial variable in understanding what drives users to utilize such applications. This study examined the role of trust and privacy in the accepted use of ambient technologies for health-related purposes. Using an online survey we collected data from N = 102 respondents. Findings revealed that participants are willing to use ambient technology for health. Benefits and barriers are traded off, whereby the advantages outweigh the perceived barriers. Trust conditions to be fulfilled include data security, technical soundness, and health-related aspects. Having control over personal information results as the most important privacy aspect, followed by the supervision of social contacts. Regression analyses revealed perceived motives and barriers, technical soundness, and health-related trust to be significant predictors of acceptance.

Research on video-based Ambient Assisted Living (AAL) technologies is increasing due to their potential of providing abundant sensory information about a person in need of support. Acceptance of these visual sensors is limited among potential users as perceptions of barriers persist, most importantly privacy concerns. The current study aimed to investigate potential users’ behavioural intention to use video-based AAL and their evaluations of relevant benefits and barriers during activities of daily living in their own homes. Special focus was on exploring the influences of individual differences (demographics and psychometrics) on evaluation patterns. In total, evaluations of 122 participants (age range: 17-81 years) were assessed through an online survey. The results are in line with previous findings on perceived benefits and barriers and their relevance to the acceptance of AAL technology. Beyond that, the results revealed significant relationships and impacts of individual differ ences, i.e., privacy perception, self-consciousness, and body consciousness, on the perceived barriers and indirectly also on the acceptance of video-based AAL technology. Further, three clusters of potential users were identified, differing significantly in their evaluation of video-based AAL technology as well as in their individual characteristics, i.e., privacy perception and self-consciousness. The findings of this study are useful to derive recommendations for user-tailored development and communication of video-based AAL technology.

Access to art and cultural heritage is an important aspect of the well-being of humans. Within the BeauCoup project, we aim to create solutions to improve access to cultural heritage for older adults with and without impairments. In this paper, we present tangible, interactive postcards, which were developed in a user-centered design process within the project. These digital tangible postcards are a cheap, ubiquitous and easily transportable solution to make artworks - especially paintings - interactively accessible to people with visual impairments. We describe the developed solutions and will strive to discuss with the community the general concept, improvements and further application areas.

Ambient Assisted Living (AAL) technologies have a high potential to combat healthcare challenges while supporting older adults to live independently at their own home. Despite the general positive uptake of such technology, perceptions of barriers of acceptance persist, a major one regards privacy. With an explorative qualitative approach, the current study aimed at investigating participantsc̀ognitive representations of a scenario in which AAL is installed in the own home as a support at an older age. Special focus was on eliciting participantsìmplications for privacy in this scenario and to understand the individual requirements of using AAL technology at home. Opinions of 12 participants (age range: 23-81 years) from Germany and Switzerland were assessed through semi-structured interviews. The paper presents descriptive results and emerging themes of the mapping approach. The results show the usefulness of the method to understand thought processes of potential users regarding pri vacy preferences and technology usage. Findings might be useful to inform technical designers as well as lawmakers to consider these usage requirements during technology or law development.
