Human – computer interaction – the intersection of computer science and behavioral sciences , this field involves the study , planning , and design of the interaction between people ( users ) and computers . Attention to human-machine interaction is important , because poorly designed human-machine interfaces can lead to many unexpected problems . A classic example of this is the Three Mile Island accident where investigations concluded that the design of the human – machine interface was at least partially responsible for the disaster
