“Usability Evaluation”: Criteria for Quality Architecture In- Use

There are varieties of health-care evaluation either for the quality of design or service, as well as the impact of those
factors to the patients or management system. Usability is one of the evaluations, which evaluate the quality in-use.
Usability approach is focusing on the method of collecting data. It is based on the exploration of the user experience
by knowing their perspective. It is measured by three parameters; the effectiveness and efficiency of the design or
facilities offered and the user’s satisfaction. The purpose of this study is to explore an understanding of the
complexity of patients who use the facilities provided. In addition it also to observe the phenomenon of patient
feedback during journey experience in the hospital spatial design and it relationship. The methods of collecting data
in this study are through walkthrough observation and interviewing patients from two public hospitals. As a result,
we identified that a variety of usability criteria contributes to the quality of architecture in-use. Most of the
respondents expressed the usability factors are caused by accessibility, reach ability and way finding criteria. Later,
all those issues will be used as measurement criteria for a main case study.
