## **评估**
|
||
|
||
- 可以确定我们正在改善用户的体验
|
||
- 需要定性、定量的数据
|
||
|
||
## **分类**
|
||
|
||
### 形成性评估
|
||
|
||
- 在设计**低保真**原型的过程中进行的
|
||
- 数据：( 例如：完成任务的时间或点击次数）（关注任务）
|
||
- 环境：一个受控环境, 例如, 实验室或办公室
|
||
|
||
### 总结性评估
|
||
|
||
- 是在**高保真**原型或最终界面即将完成的情况下进行的。
|
||
- 数据：设计者能够访问的和分析的数据， 它们可以告诉我们如何使用系统。 例如，用户开始和结束会话时可能会有时间戳， 并记录用户如何与系统交互的数据（真实场景）、
|
||
- 场景：高保真原型可在野外进行，如真实的使用场景
|
||
|
||
## **如何评估**
|
||
|
||
### 数据收集
|
||
|
||
- 以问卷形式进行的定量数据,
|
||
- 记录用户完成任务时所经过的路径的数据。
|
||
- 用户访谈的形式获得的定性数据
|
||
|
||
### 衡量
|
||
|
||
- 衡量任务的目标所达到的程度（完成程度）
|
||
- 包括完成任务的时间、单击次数或 执行任务时出现的错误数。
|
||
|
||
### 可学习性
|
||
|
||
- 定义：首次成功完成任务的简单程度。
|
||
- 衡量：完成任务的点击次数、完成任务所需的时间量来获得客观的测量结果， 然后将这些数据与专家的表现进行比较。
|
||
|
||
### 可记忆性
|
||
|
||
- 定义：要记住产品用方法的难易程度（如何在反复试验之后在界面上执行给定的任务）
|
||
- 衡量：时间量或点击次数（完成一项反复试验的任务, 以获得可记忆性的测量）
|
||
|
||
### 主观情感评估
|
||
|
||
|
||
|
||
- 认知测量：心理负担
|
||
- 情感测量：情感体验
