• 애플처럼 만들어 주세요.
• 페이스북은 xxx기능이 있던데 이건 왜 없어요?
• 엑셀보다 편하게 만들어 주세요.
• 우리 사장님은 궁서체를 좋아해요.
• 여기는 빨간색, 여기는 파란색, 여기는 노란색으로 해 주세요.
• 여기도 중요하고, 저기도 중요하고, 다 중요한데.. 여기가 제일 중요해요.

Design principles
Usefulness principle
- 사용자는 시스템을 어떻게 판단하는가?
- 시스템의 어떤 용도로 사용되는가?
- 시스템은 어떤 구조를 가지고 있는가?
- 시스템은 어떻게 작동하는가?

Design principles
Usability principle
- 얼마나 효율적인가?
- 학습이 용이한가?
- 가능한 적은 노력을 요구하는가?
- 사용자가 만족하는가?

What we have to do.“Requirements analysis” from target interface.“Benchmarking test” with comparable interfaces.“Usability testing” by empirical users.“Model-based evaluation” by CogTool.
Human factors engineering
This term project is
To evaluate “User interface” through various methods.- Experimental research method: Think aloud test
- Descriptive method: Benchmarking test, questionnaire
- Model-based method: CogTool modeling
