Visual categorization is ubiquitous in many professions, yet training programs are typically time- and effort-intensive. This work focuses on developing methods to improve human learning and performance on challenging visual categorization tasks, e.g., bird species identification, diagnostic dermatology. As part of the general approach, we infer…

Augmented reality (AR) is an interactive system that allows users to interact with virtual objects and the real world at the same time. The purpose of this dissertation was to explore how AR, as a new visualization tool, that can demonstrate spatial relationships by representing three dimensional objects and animations, facilitates students to…

Understanding the user and customizing the interface to augment cognition and usability are goals of human computer interaction research and design. Yet, little is known about the influence of individual visual-verbal information presentation preferences on visual navigation and screen element usage. If consistent differences in visual navigation…
