Note: What follows is, in some cases, examples of work that has been provided to customers, while other portions are representative examples of work that has been conducted during my career. While I would love the opportunity to share more work that I have completed in the real-world, many of the projects I work on contain proprietary or other restricted content and therefore cannot be displayed publicly.
User Interface Specification Document -- This document outlines the behavior as well as the look and feel of functionality found in a fictional commercial website that deals with the sale of automotive parts and accessories.
Cognitive Task Analysis -- The United States Air Force was interested in finding out more regarding how aircraft maintainers used technical manuals and other available documentation. The findings of this project resulted in the development of a desktop application to assist aircraft maintainers during troubleshooting.
Design Guideline 1 -- The Human Effectiveness Directorate of the Air Force Research Laboratory required the development of a document that could be used as a design reference during the transition of technical and flight manuals into a digital medium. This guideline is an example of a document that would provide guidance to designers.
Design Guideline 2 -- Many businesses are beginning to realize that there is a business case for making their web presence accessible beyond simple legal liability. In many cases, organizations are finding that having accessible content is a competitive advantage; being able to offer content to a wider audience gives organizations a leg-up on their competitors. However, many developers are unsure about the steps to take in order to provide their customers accessible content on the web. This guideline is an example of a document that would provide guidance to developers.
Concept/Usability Evaluation -- Reed Elsevier was interested in determining which conceptual design changes to one of its flagship products led to the least amount of confusion and the greatest level of user acceptance.
Conceptual Redesign -- A conceptual redesign of an air traffic control station, TRACON, was presented to representatives of the Federal Aviation Administration. The concepts presented gave the representatives a better idea of approaches that could be taken in the future design of air traffic control stations. (screenshot)
Real-time collaborative heuristic review: Meeting the production schedule without sacrificing quality. Paper and presentation for the Human Factors and Ergonomics Society 2006 conference. (2006)
The Task-Based User Interface Filter Accessibility Tool for Website Navigation. CSUN 20th Annual International Conference. (2005)
"Going in Blind Doesn't Help": Cues for Navigation. Paper and presentation for the Usability Professionals Association 2004 conference. (2004)
Internet Searching by Ear: Decision flow diagrams for sightless internet users.Paper and presentation for the Human Factors & Ergonomics Society 2004 conference. (2004)
Delivering the Message: Effectively Communicating Complex Information -- This presentation was prepared for individuals coming from a highly technical background who might need to present information in the most simple fashion to individuals who lack such a highly technical background.
UX Week: Accessibility -- This presentation was part of a series held annually at the LexisNexis UX Week.
HFES 2006 -- This was a presentation delivered by Drew Bowers and myself outlining the development of one of our web applications, Montage.
Understanding and Using JAWS -- This was part of a training presentation to introduce users to an assistive technology often used to conduct accessibility testing.
Vehicle Selection analog -- This set of concepts was an investigation of how decisions are made in the face of a possibly overwhelming number of variables. Humans make these sorts of decisions every day. One such example is that of selecting an appropriate car during the shopping process. Although automobiles are exceedingly complex systems containing numerous variables and capabilities, tradeoffs and decisions must be made by individuals who often have little or no technical background. The concepts presented here are an attempt to capture how we make some of these decisions in an objective process that can then be transferred to other domains.

Cluster concept -- This mockup was an exploration of displaying multivariate data on an interactive 2-dimensional plane. The intention was for the visualization to be both robust enough for an analyst or engineer to make informed observations during data exploration and to be presented to decision makers with less technical background in an easy to understand format.

Data Constraint concept -- Many times, engineers who use techniques such as Monte Carlo to generate data will end up creating more data than they can reasonably handle. One way in which engineers deal with this problem is to place constraint on the data in order to pare it down to something a bit more manageable. This mockup attempts to provide an interactive tool to the engineer that he or she can use to constrain the data set.

Montage -- Montage is a tool I developed in order to meet a customer need. Montage is a web-based application that enables an unlimited number of people to conduct an expert heuristic review and contribute their findings to a central repository. Secondly -- and most importantly -- Montage also allows the customer to check to see how the evaluation is going at anytime and see the team's findings in real-time. This allows the customer to begin taking action on the findings before the final report is even submitted.
Platypus -- As a team at the University of Dayton Institute we determined that it would be useful to develop a web-based questionnaire tool. The resulting application was Platypus, which allows users to design, deploy, and analyze questionnaires through a single, powerful, and easy-to-use interface.
HFES/SOH (in progress) -- Our team has been tasked with two objectives: first, redesign the Southern Ohio Chapter of the Human Factors and Ergonomics Society's website, giving it a more usable and appealing feel; second develop a content management system that can be used by the officers of the chapter to keep content of the site up to date without having to depend on the availability of the webmaster. The project is still a work in progress, but I will be adding mockups and screenshots periodically.
