Computer software engineering is the process of
producing interface products between humans and computers that are able to
provide the expected change in mindset. The aspects of cognitive ergonomics in
software engineering need to be examined and traced through various studies and
findings from experts because these references can be utilized in computer
programming. Ergonomics design is the use of information about humans, physical
and mental characteristics, capabilities and limitations, in designing tools,
equipment, machinery, work, tasks, system completion, for humans and the
environment with a holistic approach, to achieve the most optimal and maximum
human body functions both physically and mentally.
From the results of the study of several references
that discuss the findings of experts around cognitive ergonomics related to the
software engineering, found several obstacles that need to solve holistically
such as software engineering have not realized how important it is to include
aspects of ergonomics in the design created; cost factors, user willingness,
the willingness of funders and artistic dominance often confuse the design of
the software to be created; Determination of software design is sometimes only
studied based on one aspect and is not studied holistically and
interdisciplinary and does not involve the user.
Speaking of ergonomics problems in software, it is
inseparable from other disciplines namely Computer Science, Cognitive
Psychology, Social Sciences, Business, Graphic Design, and Ergonomics. In its
application, all of these disciplines produce a new concept called
Human-Computer Interaction which studies how humans interact with computers
including tasks that bind between the two.
In human-computer interaction, a piece of software
can be judged from several factors, namely: User Friendly: the system must be
designed for convenience; Error Free: even though it may not be 100%
error-free, the error rate is still within the reasonable limits to be used;
Consider the user's ability to information technology; User error tolerance and
availability of various other options for user needs.
To achieve results with these criteria, the
software must be designed according to need. Users are placed at the interface
level and not at the process level. Therefore the interface must be designed
informatively and include various elements so that users are able to make the
most of computer resources.
The interaction system translates between what the user wants and the
existing system. As an illustration that if a user wants to make a computer
sentence, then the user must first know what program can be used to write the
word. If the user does not know what program to use, there will be a
misunderstanding between the user and the system. The relationship between the
user and the computer is bridged by the interface.
Attention in knowledge and mental models in the
perspective of Human-Computer Interaction is based on the idea that by
understanding what users know about the system and their consideration of how
the system functions, it is possible to estimate the time needed to learn, the
likelihood of errors and the ease that users get in finish the job. Analysis of
the process that the user goes through, so as to gain confidence, run the
system correctly, and it is hoped that an interface can be designed to support
user acquisition correctly.
To find out the usefulness of an application, a
test is usually known as a usability test. Usability tests are implemented in
order to create software that places the user at the center or core of the
process of designing a system. Usability tests combine the desires and needs of
users in using the system to be designed. Software by implementing the
usability principle gives the possibility that the devices made are easy to use
by users.
There is a slogan about the importance of
usability, namely: "don't work, make the software usable", in the
sense of making software as easy and as useful as possible for users by
applying the usability principles and paying attention to the main tasks of
users in a piece of software so that when the user uses the software as if the
software is working for the user, not the user who is working for the software.
By paying attention to the things that users are doing, the usability principle
can be implemented in various software and system development.
