7.1 Scope and Limitations
This research study focuses on finding out user’s feelings about web interface
design by applying aesthetic theories. It covers the design principles about screen
layout design, element distribution and colour harmony on the website.
Due to the reason of limited time for the research, the researcher could only
provide two websites for the research investigation, one aesthetic-based website
and another non-aesthetic website and both websites are designed by the
researcher. As the current development of websites, there is a large number of
websites available on the Internet, that are used for different purposes and with
various design styles. It is impossible for the researcher to show all kind of
websites with different themes in her research, since developing a fully aesthetic
based website and a non-aesthetic website for contrasting is time consuming.
In addition, another limitation in this study is the research people. All the
investigation concerning this research is done inside Lahti University of Applied
Sciences. Even though, the researcher tried to avoid collecting data from a similar
group, there is still a limitation that the research could not cover all different level
of education and age.
7.2 Reliability and Validity
For testing the quality of the research, reliability and validity are commonly used
as the path for measurement. The definition of realiability and validity in
qualitative research is: Firstly, the results of the research are replicable and
retested, that can fulfill the reliability in the research. For example, in this research
paper, if somebody adopted the aesthetic rules as mentioned in this paper, they
should get similar results to this author’s results. Secondly, for validity, it is
measured for testing whether the research is accurate and process as it is intended
to be (Golafshani, 2003).
Reliability in this research paper was measured by designing the aesthetic website
