Article
Full-text available
Accessibility and inclusivity in field geology have become increasingly important issues to address in geoscience education and have long been set aside due to the tradition of field geology and the laborious task of making it inclusive to all. Although a popular saying among geologists is “the best geologists see the most rocks”, field trips cost...

Virtual and immersive virtual reality, VR and iVR, provide flexible and engaging learning opportunities, such as virtual field trips (VFTs). Despite its growing popularity for education, understanding how iVR compared to non-immersive media influences learning is still challenged by mixed empirical results and a lack of longitudinal research. This...

To incorporate immersive technologies as part of the educational curriculum, this article is an endeavor to investigate the role of two affordances that are crucial in designing embodied interactive virtual learning environments (VLEs) to enhance students’ learning experience and performance: 1) the sense of presence as a subjective affordance of t...
Conference Paper
Full-text available
Although the COVID-19 pandemic has made the need for remote data collection more apparent than ever, progress has been slow in the virtual reality (VR) research community, and little is known about the quality of the data acquired from crowdsourced participants who own a head-mounted display (HMD), which we call crowdXR. To investigate this problem...

Reference frames provide structure for spatial cognition and support spatial knowledge development across different scales. This study sheds light on the relationship between geographic scale, defined as the spatial extent visually accessible from a single viewpoint, and the preferential use of different reference frames (egocentric vs. allocentric...

The synergies of advances in environmental sensing and modeling and the mainstreaming of immersive technologies lay the foundation for a theoretical grounding of embodied digital twins. Embodied digital twins draw on an established understanding of the importance of place for environmental sciences as well as a paradigmatic shift in the cognitive s...
Article
As projects become more globally dispersed, site visits and analysis become challenging, often leading to the use of secondary information (e.g., photos, plans, and videos). Immersive technology offers embodied , visual, and spatial perspectives, providing unique information about a site that could be beneficial. Our research examines how virtual e...
Article
Full-text available
With immersive experiences becoming a medium for mass communication, we need pedagogies as well as scientific, evidence-based design principles for immersive learning. To foster evidence-based designs of immersive learning, we detail an empirical evaluation of a geosciences field trip, common in undergraduate education across numerous disciplines....
Article
Full-text available
Background: Investigating the relationship between the human body and its spatial environment is a critical component in understanding the process of acquiring spatial knowledge. However, few empirical evaluations have looked at how the visual accessibility of an environment affects spatial learning. To address this gap, this paper focuses on geog...

In this paper, we explore how the embodiment and gender of a virtual instructor can affect social presence, spatial presence, perceived learning effectiveness, and performance of students in virtual field trips. A pilot study with 22 students was conducted in the spring of 2020 in a geoscience course at The Pennsylvania State University. Our result...
Conference Paper
Mechanisms for guiding a user's visual attention to a particular point of interest play a crucial role in areas such as collaborative VR and AR, cinematic VR, and automated or live guided tour experiences in xR-based education. The attention guiding mechanism serves as a communication tool that helps users find entities currently not visible in the...

We are creating an immersive analytics tool for exploring the output of a Dynamic Integrated Climate-Economy (DICE) model, and present early work on the prototype system. DICE models and other Integrated Assessment Models (IAMs) are critical for informing environmental decision making and policy analysis. They often produce complex and multi-layere...
Article
Full-text available
The authors present four human behavioral experiments to address the question of intuitive granularities in fundamental spatial relations as they can be found in formal spatial calculi. These calculi focus on invariant characteristics under certain (especially topological) transformations. Of particular interest to this article is the concept of tw...
Article
Full-text available
Experiments in this article test the hypothesis that formal direction models used in artificial intelligence correspond to intuitive direction concepts of humans. Cognitively adequate formal models of spatial relations are important for information retrieval tasks, cognitive robotics, and multiple spatial reasoning applications. We detail two exper...
Conference Paper
We argue that Geographic Information Retrieval has a lot to gain from the creation of contextualized models of spatial relations that capture how human usage of spatial relational expressions is affected by contextual factors. We propose a framework to develop such models and discuss challenges.
