Research

My research interest is in user interfaces for ubiquitous computing applications. The ubiquitous computing vision is a world in which computers are embedded in everyday objects and become part of everyday activities. Within ubicomp, my primary focus is on mobile interfaces for users who are also involved in an eyes-busy, hands-busy task, such as operating a vehicle. I explore approaches towards creating interfaces that do not unduly increase the user’s cognitive load.

Cognitive load of HCI. Cognitive load is commonly defined as the relationship between the cognitive demands placed on a user by a task, and the cognitive resources of the user [1]. My colleagues and I have explored the performance, physiological and subjective measures of cognitive load of a number of in-vehicle tasks, such as operating a police radio [2] and interacting with personal navigation devices [3, 4]. Currently I’m particularly interested in using pupil diameter as a physiological measure of cognitive load [5]. My work focuses on estimating cognitive load in driving simulator-based experiments [6, 7], as well as under varying levels of illumination [8, 9].

HCI inspired by human-human interaction. I am fascinated by the fact that drivers with passengers have a lower probability of getting into an accident than those who drive alone [10, 11]. This fact is the basis of hypothesizing that human-human interaction can indeed provide inspiration for safe and effective HCI, even in complex environments such as a vehicle. My work is currently focused on identifying behaviors in human spoken interactions that might serve as inspiration for HCI [12-17].

Project54. I was the principal investigator of the Project54 effort at UNH, which addressed ubicomp in the law enforcement setting. This multi-million dollar effort started in 1999, and it resulted in the design and deployment of the Project54 system. The Project54 system integrates in-car devices, provides a single user interface for interaction with these devices and allows the integration of mobile police units into an agency-wide data network. Over the last decade the Project54 system was deployed in over 1,000 law enforcement vehicles, primarily in New Hampshire.
