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…

This study, involving 20 normally developing 4-year olds, found no visual sequential recall differences between direct selection and scanning in task performance. However, subjects correctly recalled fewer sequential symbols represented by Blissymbols than by Picsyms, and recalled significantly fewer three-symbol sequences than two-symbol…
