The user interface in human-computer interaction refers to the virtual space where interactions where communication occurs. The main aim is to allow effective operation and control of the machine, while the machine feeds back information at the same time. This aids in the process of decision making (Galitz, 2013). Examples of initial user interface include operating systems, heavy machinery operator controls, and process controls. In this paper, I will clearly discuss how to test the user interface and add validation code for any data entry by the user. Moreover, it has led to construction of codes in reviewing and designing codes.
Generally, the objective of user interface is to produce an effective design which makes it easy, efficient and user-friendly to operate a machine which produces the desired results. This means an operator has to key in a set of instructions in order to achieve optimum desired results in programming (Galitz, 2013). The machine responds by minimizing undesired output to the humans. Construction of the code involves a network of equipment interlinked to display information. Additionally, interaction is local to one piece of equipment. Multiple equipment are linked by a host control system. The system may produce a platform to serve several users simultaneously.
In conclusion, building, debugging and running the program involves human-computer interaction. It has been put to real life use in Medical laboratories to replace missing organs. Clearly, user interface is very resourceful in the face of technology (Galitz, 2013). Due to this invention, it is possible to input data into a computer, process it, produce desired results or output and store information which is represented in various forms.
