The Speculative Future of Conversational AI for Neurocognitive Disorder Screening: a Multi-Stakeholder Perspective

Neurocognitive disorders (NCDs), such as Alzheimer's disease, are globally prevalent and require scalable screening methods for proactive management. Prior research has explored the potential of technologies like conversational AI (CAI) to administer NCD screening tests. However, challenges remain in designing CAI-based solutions that make routine NCD screening socially acceptable, engaging, and capable of encouraging early medical consultation. In this study, we conducted interviews with 36 participants, including clinicians, individuals at risk of NCDs, and their caregivers, to explore the speculative future of adopting CAI for NCD screening. Our findings reveal shared expectations, such as deploying CAI in home or community settings to reduce social stress. Nonetheless, conflicts emerged among stakeholders, for example, users' need for emotional support may conflict with clinicians' preference for CAI's professional and standardized administration. Then, we look into the user journey of NCD screening based on the current practice of manual screening and the expected CAI-supported screening. Finally, leveraging the human-centered approach, we provide actionable implications for future CAI design in NCD screening.

3D-Mirrorcle: Bridging the Virtual and Real through Depth Alignment in AR Mirror Systems

Smart mirrors have emerged as a new form of augmented reality (AR) interface for home environments. However, due to the parallax in human vision, one major challenge hindering their development is the depth misalignment between the 3D mirror reflection and the 2D screen display. This misalignment causes the display content to appear as if it is floating above the mirror, thereby disrupting the seamless integration of the two components and impacting the overall quality and functionality of the mirror. In this study, we introduce 3D-Mirrorcle, an innovative augmented reality (AR) mirror system that effectively addresses the issue of depth disparity through a hardware-software co-design on a lenticular grating setup. With our implemented real-time position adjustment and depth adaptation algorithms, the screen display can be dynamically aligned to the user's depth perception for a highly realistic and engaging experience. Our method has been validated through a prototype and hands-on user experiments that engaged 36 participants, and the results show significant improvements in terms of accuracy (24.72% $\uparrow$), immersion(31.4% $\uparrow$), and user satisfaction (44.4% $\uparrow$) compared to the existing works.
