Hospital physicians must navigate through vast quantities of patient information represented in text-based reports. Although intended to improve patient care, their effectiveness hinges on each physician's ability to successfully handle and interpret fragmented information from diverse sources. The increasing automation of text interactions are a potential support but are still at the early phase of implementation in real-world scenarios. We observed 144 hours of clinical shifts in a German internal medicine hospital and collected structured field notes on physicians' current practices with text-based reports to enrich existing understanding of the requirements for including automation to clinical text. We identified medical discharge letters as most frequently consulted text document and a qualitative analysis of the field notes revealed that this document acts as a key artifact that serves different roles and purposes in the hospitalization of a patient. Based on our findings we discuss possible loss of these nuanced uses through automation and propose design implications for medical text reports.

Patient portals empower patients to schedule appointments, ask questions, and provide information for upcoming procedures. While patient portals provide advantages for cooperation between medical institutions and patients, provided information can be unengaging. Interactive alternatives include question prompting, which can elicit helpful questions patients would otherwise not ask; and simulations, which have been used to engage patients when informing them about medical procedures. To investigate barriers of simulations and question prompting to engage patients when informing them about a medical procedure, we developed an MRI (Magnetic Resonance Imaging) virtual walkthrough and compared task load of this procedural simulation with a standard information leaflet. After receiving information either through the virtual walkthrough or leaflet, we asked 105 participants recruited through Amazon Mechanical Turk to ask questions about the procedure either to an expert or to a peer. Comparing virtual walkthrough and leaflet, we find positive effects of the walkthrough on mental load. Investigating the linguistic properties of questions, we find experts received more technical questions; peer questions focused on the procedure’s emotional content. Our results give insight into linguistic differences in questions, contribute practical knowledge to prompt questions, and discuss the potential of virtual walkthroughs and peer questions for preparing medical procedures.

In the digital age, technology permeates every aspect of our lives, offering connectivity but also posing risks to our well-being due to overuse. The concept of "digital detox" has emerged as a response, with smartphone apps supporting this process, yet the potential of wearable tech like smartwatches is less explored. Our study develops and tests a smartwatch-integrated digital detox aid, aiming to seamlessly blend with tech ecosystems offering a holistic solution. A preliminary mixed method user study (n=6) over two weeks assessed its efficacy in cutting down phone usage and app screen time, alongside monitoring phone interactions and physiological data. Initial results showed a decrease in screen time, which diminished in the second week, suggesting participant resistance and the intervention's perceived intrusiveness. Despite proving the concept's feasibility, the need for more user-aligned intervention methods and technical enhancements is clear, pointing to areas for future improvement.

As our society ages and technology becomes increasingly omnipresent, the use of Mixed Reality (MR) in private and health related domains inevitably encounters the older population. This intersection presents unique challenges and opportunities for the integration of MR technology into the lives of elderlies. We conducted a qualitative study (N=7) using think-aloud interviews to gain in-depth insights into the usage of MR devices by elderly people. Using thematic analysis we identifed barriers and facilitators for elderly engagement with MR: emotional response, ergonomics and handling, utility, learning competence, and acceptance. Our fndings highlight the roles of timing, responsiveness, and skepticism towards the technology, which can act as a deterrent to the participation of elderlies. We contribute with a refned understanding of the elderly’s interaction with MR and recommendations for elderly-centric MR technology adoption.

Sedentary behavior has been linked to numerous detrimental health outcomes. This is particularly pronounced among office workers. Sitting breaks can attenuate some of these detrimental health effects. Thus, our goal was to design a persuasive system to prompt frequent sitting breaks in the office. With our system we want to address two key issues of existing approaches: low compliance due to lack of motivation, and user annoyance with frequent prompts. Based on a literature review, we developed four design concepts each using a different prompt modality (appearance, audio, light, movement) and evaluated them qualitatively by conducting a focus group interview with a panel of workplace health management experts (N=5) and quantitatively in an explorative online study with our target demographic (N=39) rating the concepts’ perceived persuasiveness and obtrusiveness. Based on our findings, we derive design implications for researchers and practitioners, and demonstrate their technical feasibility by providing a proof-of-concept implementation.

The rising popularity of camera glasses challenges societal norms of recording bystanders and thus requires efforts to mediate privacy preferences. We present the first study on the wearers’ perspectives and explore privacy challenges associated with wearing camera glasses when bystanders are present. We conducted a micro-longitudinal diary study (N = 15) followed by exit interviews with existing users and people without prior experience. Our results show that wearers consider the currently available privacy indicators ineffective. They believe the looks and interaction design of the glasses conceal the technology from unaware people. Due to the lack of effective privacy-mediating measures, wearers feel emotionally burdened with preserving bystanders’ privacy. We furthermore elicit how this sentiment impacts their usage of camera glasses and highlight the need for technical and non-technical solutions. Finally, we compare the wearers’ and bystanders’ perspectives and discuss the design space of a future privacy-preserving ecosystem for wearable cameras.
