Topic of this was research design. I have read the following articles: "Turn Your Mobile
Into the Ball: Rendering Live Football Game Using Vibration" by Réhman,
S., Sun, J., Liu, L., & Li, H. and "Some Principles of Research Design
in Public Health" by Rosenstock, Irwin M, Hochbaum, Godfrey M.
The first article considers the use
of vibratone for visualization of the information about football games. Mobile phones operate more and more functions. They serve
not only for communication but also for fun and games. We can watch
football on the phone and choose moments of interest. The phone can send information about
the ball during the game.
Different vibratory
signals can transmit information about physical position of the ball. You can design a
football experience with vibration. Video from the football match is analysed, encoded
into vibro-information and transmitted to the display in the form of vibration
signals.
If we consider all the elements that
influence the perception and transmission of vibration signals, it is optimal
to transmit the main events of the game. The study has monitored the following
uses of vibration sensation: transmission, methods of coding and vibrotactile definition. The following goals of technology
use have been considered in this study: effectiveness, efficiency and optimal
signal transfer. Users have been trained to acquirement
of the GUI system programming. Education based on the principle of
contact and visual stimulations. Students and administrative staff of Umea
University were involved in the studies. The participants used the vibration
function of mobile phones, 70% of them did it every day. All participants were involved in two stages of this
experiment. At the end of the two stages
participants answered a set of questions. The error rate was determined by comparing
the original data and the data received by the participants in the experiments. After processing of the data the grade
point average quality of performance was calculated. According to the results
of the data ANOVA analysis was performed. The degree of correlation between
different data provides an explanation of their complementarities.
The second article describes the
principles of roentgen studies of tuberculosis in the public health service. Several principles related to researches adopted in the
public health were considered here. It includes design issues, review of
literature, distinction between hypotheses and assumptions, data and choice of
methods.
The questions of this study were ‘Why do not people go to the
research?’ and ‘Why do people go to the research?’ This approach allowed us to
find the positive and negative aspects and explore them. The studies were
conducted in three major cities, and 1200 persons took part in them. Participants answered 90 questions in standard forms.
Research
findings and scale of their application depend on quality structure of the
research participants. The data were collected after the research.
90% of the time was spent on the research and the
remaining time was spent on processing of data.
The data of content analysis were
analysed and generalized. Interpretation and reporting of research were made
explicit.
Conclusions
In the design research first the preliminary
tests before the development of the project are conducted. The choice of
methods and technology provides the necessary data for identify goals and
challenges of the research. Review of relevant literature and assumptions, definitions
and hypotheses can clearly define measurable quantities. The research methods are defined and the samples types are selected
for use in regular research in the future.
