| Summary: | 碩士 === 國立高雄第一科技大學 === 資訊管理研究所 === 102 === There are many innovative products which have gradually changed the way and the habit of living of human beings. For example, the invention of smart phone, payment mechanism of all kinds of electronic wallets, which are all design and application of human machine interface (HMI) and the point of thinking is man-centered to design the products meeting the expectation of the users.
The main purpose of this study is to build up the Post Acute Care (PAC) information system that will apply the design and principle of human machine interface (HMI), which is a user-centered PAC information system to meet the demand and expectation of the users.
The research applied the usability engineering method to build up PAC information system step by step and simulated the prototype construction with simulation software. Further, the study carried out the usability test and thinking aloud method to correct and upgrade the usability of the system over and over again.
In summary, this study applied the usability engineering method to build up the PAC information system by means of usability test and the data recorded from in the process, and then proceed with T-test analysis with SPSS, one-way analysis of variation, and multiple regression analysis to come up with the following conclusion:
1. The improved system has more significant improvement than previous one regarding the degree of satisfaction, effects, and efficiency by usability test.
2. From part of the analysis results it is deducted that the users considered it more important on the comfort level of overall operation.
3. The frequency of error operation will be critical to the efficiency operation of the system.
