Abstract
Purpose: Evidence-based design is the process of making design decisions based on reliable research to achieve the best results, so it is important to accumulate reliable evidence through research. Therefore, the purpose of this study is to present new evidence by applying the evidence-based design process to improve the digital signage for each room spaces in hospitals and verifying its effectiveness. Method: Through the 8-step process of evidence-based design, improved digital signage for each room spaces are installed. It conducted surveys and statistical analysis to prove hypotheses by linking design and research. Results: The hypotheses established in the study are: 1) improvement in the readability of digital signage is correlated with patient satisfaction; 2) Improving the intuitiveness of digital signage correlates with patient satisfaction; 3) Improving the sufficiency of digital signage correlates with patient satisfaction. As a result of satisfaction analysis and correlation analysis, all of the above hypotheses were proven. Implications: Although the hospital sign system is the element that patients rely on most intuitively in the long journey of reception, waiting, examination, and treatment, there is insufficient evidence to refer to or apply it when designing. It is necessary to expand future research to expand the evidence that can be applied to hospital sign design.
