The MSU Libraries now provides online access to over 2,000 globally accepted SAE Ground Vehicle Standards through the SAE Digital Library. Users can view or download the SAE standards.
While there is no one definition of the term human computer interaction, Wikipedia provides this general definition “Human–computer interaction (HCI) involves the study, planning, design and uses of the interfaces between people (users) and computers.” In days of old, the 1950s, 1960s, even into the 1970s there a limited number of computers and few people actually interacted with them. These technical people often made use devices of like the teletype terminals which usually consisted of a keyboard, paper tape punch device and printer which were connected to the computer. Not much time or money was being spent on improving the user experience.
Today we have many ways of interacting with computer systems such touch screens, voice activation, gesture activation and old standbys like the keyboard and mouse. Today, because computers are embedded in so many systems that people interact with on a daily basis, they may not even realize when they are interacting with a computer. Therefore, it is more important than ever that our human-computer interactions go smoothly so the goal of today’s rapidly evolving science of human-computer interaction is to provide users with a painless and productive experience with their technology. Of course not every wonderful new innovation will live up to those expectations when it meets the real world of users.
Mechanisms can be thought of as a system of elements that transmit motion in a particular pattern while a machine can be thought of as system elements that transmit motion and energy in a predictable way. Machines are often made up of a series of mechanisms that perform work. In reality there is not a clear cut line between mechanisms and machines. Kinematics is the study of motion without considering the forces involved and kinetics is the study of forces on systems in motion. In the real world these concepts are linked. By combining simple mechanisms complex machines can be designed. Moving elements can include linkages, cams, gears, belts and chains. Bicycles contain a relatively small number of moving elements while an automotive transmission contains a large number of moving elements.
