Human Factors Psychology
Human Factors Psychology is the division of psychology that studies how the human mind and body interacts with its tools and environment. Unlike traditional psychology that seeks to understand human behavior and motivations, human factors psychology seeks to create ways in which humans can interact with the modern world in ways that are more psychologically and ergonomically friendly, rather than having to accommodate to the needs of machinery and technology.
For instance, early computers were not very user-friendly; they were large (building-sized) and used magnetic tape and punch cards to create monitor displays that were monochromatic and written in code. Now, through the combination of research and technological improvements PCs, tablets, laptops, etc. are a user-friendly, everyday feature of life.
