Design & Laws for Usable Systems

• Dix, Finlay, Aboud & Beale (2003): Introduction to “Human-Computer Interaction.”

Consider Good Human Factors

“If consideration for good human factors is given early in the design process, considerable savings in both money and possibly human suffering can be achieved.” -- Wickens, Lee, Liu & Gordon-Becker: Chapter 1 of “Introduction to Human Factors Engineering.”

“The system must support the user’s task: if the system forces the user to adopt an unacceptable mode of work then it is not usable.” -- Dix, Finlay, Aboud & Beale (2003): Introduction to “Human-Computer Interaction.”

"In other words, companies would be wise to invest early and often in a well-thought user experience for their products and services. Too many companies believe that their brand recognition will suffice when launching and maintain products. This is just not the case anymore in our day and age. A successful company will invest time into testing the usability of their products to ensure they aren’t wasting time and money focusing in the wrong areas." -- Ryan Stone
