Human-computer interaction (HCI) is about how humans interact with technology. It deals with how humans work with computers and how computer systems can be designed to best help users achieve their goals. There is a gap to bridge, between computer technology on one side and the human operator on the other. The first of what can be called modern computers, such as users required to program the computer by connecting cables on a patch board. Later, a less cumbersome user interface became possible in the form of punched tapes or cards used as input and output. Say no to plagiarism.

It has been shown that HMI theories are not yet fully established and that the discipline is highly fragmented, making it difficult to characterize a single method of approach or even a set of accepted principles. The lack of agreement between authorities in this area suggests that the approach needs to be carefully tailored to the specific needs of the environment to which it is applied. This section briefly reviewed the history of HMI, which showed how usability became the central element of virtually all HMI activities beginning in the 1960s. The structure of HMI has been reviewed to show how it encompasses a a number of disciplines. The approach to HMI analysis has evolved into the methodology of Lindgaard et al which focuses on user needs [5]. This is a commonly adopted approach and will be discussed in more detail when the methodology for this project is reviewed. Due to the fragmentation of HMI principles, it was deemed necessary at this stage to perform a frequency analysis of HMI authors and chosen principles. This was done based on the key features that each author cited as being most important. The goal was to produce a set of principles that would be considered the most accepted. It was found that eight rules were established by this analysis.
