The field of Sports Human-Computer Interaction (SportsHCI) investigates interaction design to support a physically active human being. Despite growing interest and dissemination SportsHCI literature over the past years, many publications still focus on solving specific problems in given sport. We believe benefit generating fundamental knowledge for more broadly advance as whole. To achieve this, we aim identify grand challenges SportsHCI, which can help researchers practitioners developing...
Interactive technology has a complicated relationship with recreation in nature. Many people have praised, and many lamented the impact of interactive on Because nature important wellness benefits is likely to remain part recreation, there need design for recreation. Unfortunately, little generalized knowledge exists how such technology. We create new intermediate by drawing from others' work, our prior specifically Borgmann Verbeek's philosophies Our contribution framework based...
Understanding temporal effects of fire frequency on plant species diversity and vegetation structure is critical for managing tallgrass prairie (TGP), which occupies a mid‐continental longitudinal precipitation productivity gradient. Eastern TGP has contributed little information toward understanding whether vegetation–fire interactions are uniform or change across this biome. We resampled 34 fire‐managed mid‐ late‐successional ungrazed remnants occurring dry to wet‐mesic moisture gradient...
Western Maryland's population of Ursus americanus (American Black Bear; hereafter Bear) was nearly extirpated by the 1950s but recovered to 326 individuals 2005. A knowledge gap currently exists regarding home-range dynamics this recovering population. One most basic questions that managers wish understand is how much space these Bears are using. To provide information, we examined 18 adult female in western Maryland from 2006 2007 using GPS collars. We predicted estimates our study would be...
HCI in outdoor recreation is a growing research area. While papers investigating systems specific domains, such as biking, climbing, or skiing, are beginning to appear, the broader community just form. The still seems lack cohesive agenda for advancing our understanding of this application domain. goal workshop bring together individuals interested outdoors review past work, build unifying agenda, share ongoing encourage collaboration, and make plans future meetings. will result report...
Headmounted displays (HMDs) are evaluated as a tool to facilitate studentteacher interaction in sign language. Deaf or hardofhearing children who communicate language receive all instruction visually. In normal deaf educational settings the child must split visual attention between signed narration and aids. Settings which aids distributed over large area particularly difficult. Sign displayed HMDs may allow keep sight, even when not looking directly at person signing. Children from...
We present a method for fabricating prototypes of interactive computing devices from clay sculptures without requiring the designer to be skilled in CAD software. The creates "what you sculpt is what get" process that mimics see processes used interface design 2D screens. Our approach uses modeling basic shape device around 3D printed representations, which we call "blanks", physical interaction widgets such as buttons, sliders, knobs and other electronics. Each blank includes 4 fiducial...
Few data are available that compare long-term changes in burned and unburned prairie remnants the eastern part of tallgrass region. To assess effects on species richness composition, 1996 we resampled three dry four dry-mesic sand were originally sampled 1976. Three these sites managed with burning over 20 y period not, allowing a comparison temporal change among sites. Mean native per plot increased only declined In contrast, alien prairies, an increase grasses Bromus inermis Poa pratensis...
Despite extensive use, few studies have thoroughly tested competency of the Florist Quality Index (FQI) to assess vegetation quality by comparing it with alternative statistics and independent measures in large data sets. We compared efficacy species richness floristic indices detecting temporal change fire effects on within among tallgrass prairie remnants. calculated at small (1/4-m2 plot) (total sample) scales, as well from a Species Richness (SRI) that integrates these measures. These...
Abstract Animating trees in wind has long been a problem computer graphics. Progress on this is important for both visual effects films and forestry biomechanics. More generally, progress tree motion may inform future work two‐way coupling between turbulent flows deformable objects. Synthetic turbulence added to coarse fluid simulation produces convincing animations of but the enriched flow objects embedded not investigated. Prior models lacks subgrid resolution model. We produce realistic...

Automated trust negotiation is the process of establishing between entities with no prior relationship through iterative disclosure digital credentials. One approach to negotiating for participants exchange access control policies inform each other requirements trust. When a policy received at run-time, compliance checker determines which credentials satisfy so they can be disclosed. In situations where severed sets and some are sensitive, that generates all necessary insure succeeds...
Recent studies show that a key contributor to congestion and increased CO2 emissions within cities are drivers searching (or cruising) find vacant on-street parking space. It has been shown approximately (depending on the city) 20-30% of vehicles in congested urban areas were cruising space with search time varying order several minutes. In city Bristol alone, we have shown, using our collected trip publicly available census data over 790 metric tons is generated every year due cruising. At...
Many people enjoy hiking as an outdoor escape from everyday life. However, in our survey of 1002 respondants the United States, 95% respondents indicate that they prefer to bring their cell phone when hiking. This potentially creates distractions by reminding hikers daily pressures sought escape. We believe technology has ability enable or enhance activities, such hiking, without taking away experience. But begin realize this vision we must first understand current attitudes towards...
Over the last half century, proportion of humans living in cities has dramatically risen from around a third to just over half. As continue rise popularity, demand for basic services such as transportation increases. The automobile been dominant method inner city many across globe, resulting increased congestion and air pollution. rises, so does number vehicles, which leads greater competition publicly available parking spaces. Use land can be an inefficient use space, it is expensive, both...
Mobile and wearable computing has great potential to support alpine outdoor sport activities. This includes, but is not limited to, rock climbing, hiking, mountain biking, paragliding, skiing. Interestingly, technology for tracking, monitoring supporting activities broadly used in sports like running or cycling, reached the top of mountains yet. Nevertheless, such technologies could people many scenarios as activity navigation, emergency support. Technologies applications mountaineers can...
We have built a functional prototype of mobile phone app that allows children who are deaf to look up American Sign Language (ASL) definitions printed English words using the camera on phone. In United States, 90% born parents not and do know sign language [3]. many cases, this means child will be exposed fluent in home can delay child's acquisition both their first signed secondary written [1]. Another consequence is outside school may easy access people or services translate into ASL...
Over the last 15 years, we have witnessed a digitalization of sports experience, i.e., many been enhanced by digital and wearable devices. The centrality human body different contexts where can be practiced led HCI research to explore how mobile devices could support physical, social, environmental aspects disciplines. Yet, field & continues evolve under push new technological developments events affecting people worldwide, such as Covid-19 pandemic climate change. Technological advancements...
