現今有許多創新的產品，逐漸在改變人們的生活習慣方式，例如智慧型手機的出現，各種電子錢包的付費機制等，這些都是屬於人機介面的設計與應用，並且主要都是以人為中心的思考角度，設計符合需求期待的產品為主。
本次研究中已建立PAC(Post-acute Care)資訊系統為主要目地，應用人機介面的設計與原則，希望以使用者為中心的方式建立PAC資訊系統，符合使用者需求與期待的資訊系統。
研究模式利用使用性工程方法，逐步建立PAC資訊系統，運用使用性工程方法，以模擬軟體來模擬原型建構，並且實施使用性測試及放聲思考的方式，反覆修正提升系統的使用性。
最後結論以使用性工程方法建立了PAC資訊系統，並藉由使用性測試及過程中所記錄的數據，以SPSS進行T檢定分析，單因子變異數分析以及多元迴歸分析所得到的結論如下：
一、 改良型使用性測試比使用性測試在滿意度、效能、效率上有顯著改善。
二、 由部分分析結果推論使用者較重視整體的操作舒適度。
三、 操作的錯誤次數，足以影響系統的效率運作。

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.
