The Center for Human-Computer Interaction is an interdisciplinary research center jointly sponsored by the Institute for Creativity, Arts, and Technology; and the Institute for Critical Technology and Applied Science at Virginia Tech.


Human-Computer Interaction (HCI) is a multi-disciplinary enterprise, drawing from the human sciences, computational sciences and engineering, and information technologies. The Center for HCI (CHCI) at Virginia Tech is a university-wide research center that addresses both the facilitation and the foundational understanding of human interaction with and through technology. The CHCI excels in cross-disciplinary research on interactive computing that extends into the everyday life of individuals, groups, and societies. The CHCI fosters research excellence through funding programs, shared resources, and forums for idea exchange.

TaskAmbient: an ambient information display system


TaskAmbient, designed by CHCI/Computer Science graduate student Sheriff Jolaoso, is an ambient information display system that provides a visualization overview of a user's to-dos. TaskAmbient has the ability to source to-dos from to-do applications and calendar applications. This tool has been designed to aid users in retaining information about their day-to-day to-dos from their calendar and to-do applications. It also provides a glanceable overview of tasks in a user's various areas of responsibility.

Visuoperceptual Design Considerations for Mobile AR Displays

2015-02-20 at 08:30:00 in MAC/ICAT Sandbox

Presenter: Dr. Joe Gabbard

Abstract: As public interest and curiosity in mobile, wearable computing is on the rise, technology companies are rushing to develop wearable augmented reality (AR) display systems with embedded lightweight computing capabilities that strive to make mobile living effective, convenient, pleasant and aesthetic. While we are already seeing some successful first-generation, commercially available lightweight wearable AR systems, the full potential of opportunities for mobile users (pedestrians, bicyclists, motorists) and associated displays has not been fully tapped, nor the visual perceptual challenges widely understood. As we race to field outdoor AR applications for mobile computing, we need to first understand, and then design for, the visuoperceptual issues that have been documented in the traditional AR community.

This talk presents key visuoperceptual issues inherent in commercial optical see-though displays and applications. Using examples from our experiences researching and evaluating AR interfaces, we illustrate the potential impact on user perception and task performance.

Bio: Dr. Gabbard's work centers on human-computer interaction; specifically usability engineering for novel user interfaces including (but not limited to), 3D visualization and interaction in augmented and virtual environments, multimodal interactive systems, and visualizations for life sciences using big data. Gabbard has been a pioneer in usability engineering with respect to applying to, and creating methods for, new interactive systems for more than 18 years. Dr. Gabbard has conducted numerous user-studies in augmented reality examining human performance in applied (usability engineering) and basic science domains (color perception, occlusion, depth perception). Gabbard was the lead usability engineer on the design and development of one of the first mobile head-worn AR systems (the Battlefield Augmented Reality System). Currently, Dr. Gabbard is researching visual perception in outdoor augmented reality systems to inform design of effective head-worn and automobile-based AR user interfaces.
