    HCI is increasingly paying attention to sports, and more and more CHI attendees are aiming to maintain being physically active while attending CHI. In response, we offer a SIG on the topic of sports-HCI and conduct it in a sportive way: we will go out of the conference venue and jog around San Jose while discussing the role of HCI in relation to sports. The goal is to actively shape the future of the field of sports-HCI

    Grand Challenges in SportsHCI

    Get PDF
    The field of Sports Human-Computer Interaction (SportsHCI) investigates interaction design to support a physically active human being. Despite growing interest and dissemination of SportsHCI literature over the past years, many publications still focus on solving specific problems in a given sport. We believe in the benefit of generating fundamental knowledge for SportsHCI more broadly to advance the field as a whole. To achieve this, we aim to identify the grand challenges in SportsHCI, which can help researchers and practitioners in developing a future research agenda. Hence, this paper presents a set of grand challenges identified in a five-day workshop with 22 experts who have previously researched, designed, and deployed SportsHCI systems. Addressing these challenges will drive transformative advancements in SportsHCI, fostering better athlete performance, athlete-coach relationships, spectator engagement, but also immersive experiences for recreational sports or exercisemotivation, and ultimately, improve human well-being

    Biophysical Modeling of Mangrove Seedling Establishment and Survival Across an Elevation Gradient With Forest Zones

    Mangrove forest development critically depends on the establishment and survival of seedlings. Mechanistic insights into how water levels, waves and bed level dynamics influence the establishment process of individual mangrove seedlings are increasing. However, little is known about how spatial and temporal changes in water levels, waves and bed level dynamics across elevation gradients in mangrove forests facilitate/limit seedling dynamics. For this study, a new seedling establishment and growth model was integrated into a process-based hydrodynamic and morphodynamic numerical model. This biophysical model was applied to a fringing mangrove forest located in the southern Firth of Thames, Aotearoa, New Zealand. This study quantifies the increasing establishment density and survival probability of mangrove seedlings from the lower-elevated unvegetated intertidal flat toward the higher-elevated mature mangrove forest. Three cross-shore zones with distinctive seedling dynamics were identified: (a) a zone with daily tidal inundation where seedling dynamics are episodic and limited by the dispersal of individual propagules that rapidly anchor to the substrate by root growth, (b) a zone with daily to bi-weekly tidal inundation where seedling dynamics respond to variations in spring-neap tidal cycles and, (c) a zone with less than bi-weekly inundation where seedling dynamics are governed by high propagule supply and seedling survival probability. The seedling establishment density and survival probability are dominated by annual extremes in tidal hydroperiod and bed shear stresses, respectively. The obtained parameterizations can be used to incorporate seedling dynamics in decadal-timescale mangrove forest development models that are instrumental for mangrove management and restoration

    Understanding sports-HCI by going jogging at CHI

    More and more technologies are emerging that aim to support sports activities, for example there are jogging apps, cycling computers and quadcopters for sportspeople to videorecord their actions. These new technologies appear to become more and more popular, yet interaction design knowledge how to support the associated exertion experiences is still limited. In order to bring practitioners and academics interested in sports-HCI together and examine the topic "in the wild", we propose to go outside and jog around the CHI venue while using and discussing some of these new technologies. The goal is to investigate and shape the future of the field of sports-HCI
