Envisioning, designing, and implementing the user interface require a comprehensive understanding of interaction technologies. In this forum we scout trends and discuss new technologies with the potential to influence interaction design. --- Albrecht Schmidt, Editor

Traditional meetings involve extensive sitting, which negatively impacts the health of attendees. Understanding how technology can facilitate integrating physical activity into the workplace, such as in walking meetings, is vital to improving workplace wellbeing. To that end, we applied a mixed-method approach to explore requirements and opportunities for walking meetings. We conducted an online questionnaire and a series of interviews with early adopters of walking meetings and created design fictions based on their feedback. We evaluated the design fictions with a second questionnaire and garnered additional feedback from the original early adopters. Based on our findings, we derived four dimensions associated with walking meetings: practical, environmental, social, and cognitive facets. We define attributes, challenges, and opportunities within these dimensions which are important for designing systems that support walking meetings. Our work identifies key considerations for developing systems that integrate physical activity into communication activities.

Figure 1: MindPhone is an intervention for absentminded smartphone use that asks users upfront about either their planned smartphone use intention or planned activity after the smartphone use. The latter method signifcantly reduces quantitative smartphone use and both empowered users to refect and feel more in control of their usage.

The emergence of affordable consumer drones promises new perspectives for interacting with the physical world around us. Affordable, accessible, and easy to operate drones have the potential to overcome geographic boundaries between users living in different locations and subsequently foster connectedness. Yet, the design space of using drones to facilitate social interactions beyond geographic boundaries is still underexplored. In this position paper, we envision principles derived from the concept of lucid engagement and the psychological need for connectedness to explore how drones can mediate social interactions. We introduce our design concept and discuss it based on a specific application scenario. We discuss the opportunities and challenges related to our interaction concept. Finally, we outline next steps for future research.
