Robert Hubal has general interest in the intelligent use of technology to better train and assess knowledge and skills. He is active in projects involving areas such as adaptive learning, linguistic analysis, behavior modeling, and machine learning. He has past experience developing embodied conversational agents for interaction skills training and situated assessment; conducting cost-effectiveness studies of simulation training systems; conducting expertise, linguistic codability, and mental modeling studies; investigating adaptive intelligent tutoring; implementing patterns of life into the portrayal of activity within game-based environments; and investigating visual analytics and representation.
Hubal’s research has centered on four overlapping areas:
Technology Assisted Learning
Hubal has extensive experience in developing situated training and assessment systems, always working with subject-matter experts to design the most appropriate and focused systems. Examples include evaluating the cost-effectiveness of simulation training systems; developing adaptive intelligent tutoring; developing intelligent virtual advisors; developing an information-processing model of experts’ knowledge and skill; exploring augmented cognition and user-sensing technologies for simulation training systems.

Intelligent Virtual Humans
Hubal has developed behavioral software that enables virtual humans to act and behave realistically in controlled learning contexts. Applications developed include assessing medical practitioners in history taking for both asthmatic and pediatric patients; training civilian police officers in how to handle mentally disturbed individuals; training telephone and field interview staff in obtaining respondent participation. Developed virtual vignettes to assess social functioning deficits in at-risk youth. Investigated models of cultural daily activities and patterns of life integrated into simulations of intelligent virtual humans.

Hubal has developed a number of applications focuses specifically on medical and clinical settings. Approaches are to train clinicians on difficult content and skills, augment their practices by providing simulation environments to capture important diagnostic details, and improve patients’ understanding of processes and procedures.

Visual Analytics, Emotion, and Representation
Hubal has investigated visual analytics, which allow for looking at data prospectively and visually. He has studied approaches to deriving mental models to ultimately develop training to encourage adaptive thinking about test, measurement, and diagnostic equipment, with the intent to develop an approach to modeling the structure and process of knowledge and skills and to determine an approach to identifying differences between experts’ models and novices’ models. Interested in modeling emotion in and extracting emotion from dialog. Developed a process model for alternative representations and investigated the interaction between expertise and representation.
