Emerging Human Factors and Ergonomics Issues for Health Care Professionals
Published in Jack M. Winters, Molly Follette Story, Medical Instrumentation, 2006
In its publication, Do It by Design, the U.S. Food and Drug Administration (FDA) suggested the following: Good user interface design is critical to safe and effective equipment operation, installation, and maintenance. Human factors should be considered early in the design process, and systematic analysis and hands-on testing should be conducted throughout development stages and involve participants from the end-user population. It is not simply a matter of “fine tuning.” Thorough attention to design will result in safer, more usable devices and, correspondingly, fewer accidents, reduced training costs, fewer liability problems, and less trial-and-error during device development [1].
Visual Design Principles for Usable Interfaces

The previous description is unfortunately an accurate analogy of many users’ experiences as they attempt to learn, work, play, and relax. New products, new services, and new technology with which you are unfamiliar can create confusion. Users of these new products, services, and technology are customers, electricians, grandparents, clerks, pilots, and students—you and me. And for most of us, it’s a jungle out there! Las Vegas at night with fireworks, or monitors that are winking, blinking, distracting, disturbing, overwhelming—and, after a short time, visually deafening. Now add voices coming from boxes ...! Although this may seem like an exaggeration, for many this situation is exactly their experience. User interface design focuses on designing flexible environments that have a positive impact on a user’s ability to experience and interact with a product, whether that product is a mobile communication device, website, information kiosk, or appliance. It involves creating environments that include strong navigational devices that can be understood intuitively and used effortlessly. Designers have a responsibility to create user experiences that are simple and transparent. To do their job well, they must advocate on behalf of the user, ensuring that the interfaces they design are not just merely exercises in technology but that they truly assist and guide the user from task to task, enabling work to be done, and ultimately improving quality of life. When designers succeed, their products can be used effortlessly and are even pleasurable to use. Good design does not needlessly draw attention to itself. It just works. This is the role of good design.
Development of an Ergonomic Tool to Predict Carpal Tunnel Syndrome Risk Based on Estimated Carpal Tunnel Pressure
Published in IISE Transactions on Occupational Ergonomics and Human Factors, 2018

A graphical user interface (GUI, Figure 3) was developed to provide a user-friendly ergonomic tool (MATLAB, “graphical user-interface design environment” GUIDE, Mathworks, 2009). Input variables manipulated by the user are wrist FE, RUD, pronation/supination, finger posture, as well as fingertip load and type (fingertip pinch or press).
