HCI in outdoor recreation is a growing research area. While papers investigating systems in specific domains, such as biking, climbing, or skiing, are beginning to appear, the broader community is just beginning to form. The community still seems to lack a cohesive agenda for advancing our understanding of this application domain. The goal of this workshop is to bring together individuals interested in HCI outdoors to review past work, build a unifying research agenda, share ongoing work, encourage collaboration, and make plans for future meetings. The workshop will result in a report containing a research agenda, extensive annotated bibliography, an article about this topic and plans for unifying the community at future meetings.
