The Effect of Psychological Human Factors on System Usability

Abstract

Humans are a key element of the overall system, in addition to the hardware and software

components, and therefore, human factors (anthropometric, sensory, psychological and

physiological) need to be considered in design early and often (Blanchard & Fabrycky, 2011).

With emphasis on the psychological human factors, this paper will discuss the impacts and risk

that these human factors impose on designing for usability, testing for usability, and the user

acceptance and use of the overall system during utilization. After exploring the complications

and impacts of the psychological human factors, it is necessary to address how to account for

them. This paper will, therefore, address recommendations for considering usability and human

factors in design, testing, and user acceptance of the finished system.
