A) select one example to outline the key concepts of human-computer interaction. Reflect upon the role of the âhumanâ, the âcomputerâ and the âinteractionâ.
The main concept for Human Computer Interaction is design. The interface of the machine must be simple and easy to use in order for it to be efficient and thus successful. You can “design better interfaces from the start by knowing human limitations and easing the load on the user” (Anon, 2017). A complex and hard to use interface merely leaves the user unable to grasp and understand how the machine can be of use, and how it functions. Design is within the physical layout of the computer as well as its programming and its layout. For instance when it comes to a laptop, its design must be appealing to the user. If the keyboard keys for example were shuffled and changed around then it would be less efficient for its users, interaction is about efficiency, the more complex it is to interact with the less efficient it is.
The human has the job to learn the functions, the tools, and the layout of the computer in order for it to have a maximized efficiency, if a designer relocated the keys on a keyboard it would be more complex and different to what the human may previously had remembered on other designs. Therefore it is crucial for designers to consider past adaptations, and use such examples to make a product as easy to use as possible. Though regardless the human has the role of being able to learn and remember how their inputs achieve desired outputs. For example one could easily learn that by interacting with the interface and pressing ‘Ctrl’ + ‘C’ on the keyboard that a highlighted image or text on screen has been copied.

The role of the Computer is very simple, it must remember what inputs create which outputs and must be quick and efficient at producing the desired demands of the human. However, although the computer has an important role, if it is poorly designed , then it may not be a successful product. “Interaction is about Efficiency” (Peter Kottas, 2017)
