Schumacher, Robert, North, Robert, Quinn, Matthew, Patterson, S., Militello, Laura G., Fairbanks, Rollin J. (Terry) and Gibbons, M. Chris (2012): What Can Human Factors Contribute to Improve Electronic Health Record Usability and Patient Safety?. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 763-766.
The panel brings together diverse perspectives to bear on one critical question: (1) How can human factors methods improve usability in order to protect patient safety with the use of electronic health records? Panelists represent the viewpoint of the government's role in encouraging collaboration and use of best practices, best practices in electronic health record evaluations for hospitals and special considerations for pediatric populations, the role of workflow in protecting patient safety, applying cognitive task analysis and abstraction hierarchies to inform imaging system design, and the influence of health disparities on the use of consumer health products by patients.

Fusco, Marc, Gattuso, Jr. Nicholas and Schumacher, Robert (1991): VVM: An Exploration in Screen-Based Telephony. In ACM SIGCHI Bulletin, 23 (4) p. 66.
Communications technology has evolved so rapidly that many features provided to the average user are underutilized. One of our goals for the future is to provide the user with an easy-to-use interface to all network services and capabilities. Screen-based telephony may provide a practical and functional interface by which a user can access and control their voice communication services. VVM is a screen-based interface to a voice processing system currently implemented on a personal computer. Laboratory usability testing has enabled use to refine the present design and impending field trials will provide us with qualitative and quantitative data in order to assess if users utilize more system-provided capabilities for voice processing that is currently used. This endeavor will enable greater understanding of what underlies the success or failure of screen-based telephony and allow us to validate assumptions that screen-based telephony has the potential to improve a wide range of voice services.

Mrazek, Deborah, Cocklin, Tom, Schumacher, Robert, Virzi, Robert A. and Chalupnik, Kay (1991): Now that You Have a Usability Lab, How Do You Make It Effective?. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 666-667.
Our presentation two years ago discussed how to design a Usability Lab. Now that you've done that, it's time to talk about how to use a Lab Effectively. Our hope is that this session will let you walk away with new ideas, practical tips, things to avoid and a better understanding of how to get the most out of the investment you have made in building a Usability Lab. Our panel is made up of five people who currently mange Usability Labs. Discussion topics range from objective setting and data collection methods to how well the usability lab is received by development teams. Each panel member will focus on one of these aspects. Our intent is to combine formal presentations with audience discussion. In order to do this, we ask that you be prepared to help list specific areas of interest at the beginning of the session so that presenters can address these issues. Any topics not covered during the formal presentations will be used as the discussion topics for the end of the session.

Hanisch, Kathy A., Kramer, Arthur F., Hulin, Charles L. and Schumacher, Robert (1988): Novice-Expert Differences in the Cognitive Representation of System Features: Mental Models and Verbalizable Knowledge. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 219-223.
The relationship between users' mental models and their verbalizable knowledge of a system were investigated in a field study. Trained and untrained users of a new phone system rated the similarity of use of nine phone features. Their ratings of the features were used in a multidimensional scaling technique and hierarchical cluster analysis to obtain their mental models of the system. Individuals' ratings of features on unidimensional scales about the use of the features and scores obtained on a knowledge test were reflected in their mental models. Mental models of the two novice groups' were very similar except for the perception of one feature; it was more accurately depicted in the mental model of users who attended than those who did not attend a training program. Trainers' and system designers' mental models of the phone system were evaluated to determine an "appropriate" expert mental model. A comparison of the "expert" mental model to the novices' mental models suggested that several features were inaccurately perceived by the novices. Using the discrepancies between the expert and novices' mental models to design training programs for systems is discussed. A novel way to design or redesign systems based on novices' mental models of systems is proposed.
