HCI, or in its full extent, human-computer interaction, refers to the research around design and the use of computers and how humans interact with the machines.

Those working in this field look at how people use computers and at the same time look for new designs and ways to improve user experience when interacting with the machines.

Some fields of study in human-computer interaction include computer science, behavioural sciences, design, and media studies.

There are 13 different principals around human-computer design. These include making displays legible (or audible), avoid absolute judgment limits, top-down processing, and redundancy gain.

Furthermore, those working in this field will be looking at similarity causes confusion, and principle of pictorial realism.

In addition, there is the principle of the moving part, minimising information access cost, proximity compatibility principle, principle of multiple resources, replace memory with visual information, principle of predictive aiding, principle of consistency.
