Virtual reality can be used to enhance education, especially in the remote context. Cross-reality interfaces can be useful for users who wish to access shared virtual spaces from different devices. Emotion recognition can then be used to supplement the lost non-verbal cues and allow teachers to address students in need. We introduce several types…

Interacting with objects in virtual reality can be an exciting experience. Haptic feedback allows virtual environments to appear more immersive. Does this increased immersion bear the potential to enhance learning if used properly in educational VR environments? This dissertation pursued two goals. First, to investigate the relationship between…

In the age of big data, interactive data visualizations are becoming increasingly prevalent. The ability to focus on subsets of data is essential for exploring large temporal, geospatial, topical, and network datasets. In order to categorize all parts of data visualizations, various attempts have been made to build frameworks for how to interpret,…

This dissertation explores the use of geometric and graphical models for a variety of information search and filtering applications. These models serve to provide an intuitive understanding of the problem domains and as well as computational efficiencies to our solution approaches. We begin by considering a search and rescue scenario where both…

This study examined the effects of manipulating the modality (text-only, voice-only, voice+text) of a tutorial and restriction (restricted vs. unrestricted) of a simulation's interface on retention and transfer of tutorial content. The tutorial prepared novice students to use Packet Tracer, a simulation developed by Cisco that teaches network…
