Hybrid meetings have become common practice in collaborative work environments. However, they are constrained by the fixed spatial configurations of videoconferencing technology. This limits opportunities for mobile and spontaneous interactions; qualities that are critical to successful collaboration. In this paper, we explore the concept of radically mobile hybrid meetings. Our work investigates the design space of multimodal devices as mobile alternatives to traditional videoconferencing. We conducted three group co-design sessions, where participants prototyped mobile hybrid meeting technologies to explore how such meetings could be supported. From these workshops, we derive design fictions envisioning future uses of these technologies, which we evaluate with a questionnaire to spark reflections on future mobile hybrid collaboration tools and practices. We contribute an initial exploration of the design space for radically mobile hybrid meetings, laying the groundwork for developing tools that enable spontaneous, effective, and inclusive collaboration in hybrid mobile settings.

This paper introduces MouthIO, the first customizable intraoral user interface that can be equipped with various sensors and output components. MouthIO consists of an SLA-printed brace that houses a flexible PCB within a bite-proof enclosure positioned between the molar teeth and inner cheeks. Our MouthIO design and fabrication technique enables makers to customize the oral user interfaces in both form and function at low cost. All parts in contact with the oral cavity are made of bio-compatible materials to ensure safety, while the design takes into account both comfort and portability. We demonstrate MouthIO through three application examples ranging from beverage consumption monitoring, health monitoring, to assistive technology. Results from our full-day user study indicate high wearability and social acceptance levels, while our technical evaluation demonstrates the device’s ability to withstand adult bite forces.
