    What can GIS + 3D mean for landscape archaeology?

    Until recently Geographic Information Systems (GIS) have held center stage in the archaeologist\u27s geospatial toolkit, and there is no doubt that archaeologists have moved beyond the mapdbut into what? In the early years, criticisms voicing GIS as environmentally-deterministic were abundant. What methods and tool have archaeologists used to overcome these criticisms? New geospatial technologies such as airborne lidar and aerial photogrammetry are allowing us to acquire inordinate amounts of georeferenced 3D datad but do these 3D technologies help overcome criticisms of environmental determinism? TogetherdGIS þ 3Dd can link georeferenced 3D models to underlying data adding a ground-based humanistic perspective lacking in the bird\u27s eye view of traditional GIS. This paper situates GIS and 3D within a semiotic framework to offer some ideas on using 3DGIS to intertwine environmental and cultural factors to work toward new approaches for landscape archaeology

    Collaboration Surrounding Beacon Use During Companion Avalanche Rescues

    When facing an avalanche, backcountry skiers need to work effectively both individually and as a group to rescue buried victims. If they don’t, death is likely. One of the tools used by each person is a digital beacon that transmits an electromagnetic signal. If buried, others use their beacons to locate victims by searching for their signals, and then dig them out. This study focuses on the collaborative practices of avalanche rescue and the interactions with beacons while backcountry skiing. We conducted interviews with backcountry recreationists and experts, and we observed avalanche rescue practice scenarios. Our results highlight aspects and challenges of mental representation, trust, distributed cognition, and practice. Implications include three considerations for the redesign of beacons: simplicity, visibility and practice

    Integrating passive ubiquitous surfaces into human-computer interaction

    Mobile technologies enable people to interact with computers ubiquitously. This dissertation investigates how ordinary, ubiquitous surfaces can be integrated into human-computer interaction to extend the interaction space beyond the edge of the display. It turns out that acoustic and tactile features generated during an interaction can be combined to identify input events, the user, and the surface. In addition, it is shown that a heterogeneous distribution of different surfaces is particularly suitable for realizing versatile interaction modalities. However, privacy concerns must be considered when selecting sensors, and context can be crucial in determining whether and what interaction to perform.Mobile Technologien ermöglichen den Menschen eine allgegenwärtige Interaktion mit Computern. Diese Dissertation untersucht, wie gewöhnliche, allgegenwärtige Oberflächen in die Mensch-Computer-Interaktion integriert werden können, um den Interaktionsraum über den Rand des Displays hinaus zu erweitern. Es stellt sich heraus, dass akustische und taktile Merkmale, die während einer Interaktion erzeugt werden, kombiniert werden können, um Eingabeereignisse, den Benutzer und die Oberfläche zu identifizieren. Darüber hinaus wird gezeigt, dass eine heterogene Verteilung verschiedener Oberflächen besonders geeignet ist, um vielfältige Interaktionsmodalitäten zu realisieren. Bei der Auswahl der Sensoren müssen jedoch Datenschutzaspekte berücksichtigt werden, und der Kontext kann entscheidend dafür sein, ob und welche Interaktion durchgeführt werden soll
