PSCR 2021: Make Technology Usable – Operational Human Factors and Ergonomics Guidelines



Yee-Yin Choong, Gavriel Salvendy


We present Human Factors and Ergonomics (HFE), and usability-based methods for the development and implementation of communication technology for first responders. HFE enables the design of technologies for efficient, effective, safe, and comfortable human use. Usability evaluation provides explicit information on where technologies need improvement and how to improve. Based on interviews of 193 first responders, 107 categories of technology problems and needs were identified. Applying HFE principles and usability evaluation methods, specific operational recommendations are provided to reduce or eliminate the problems and to address the needs identified; result in greater efficiency, effectiveness and first responder satisfaction.
