前言
在上一章中，我们简单地介绍了沉浸式可视化的相关概念，及几个研究团队。本章将讨论一些具体的问题。
一个示例场景…
设想一个基础的场景：
一组分析人员正在就某个任务进行讨论。他们可以使用手持平板电脑、大型屏幕、或者头戴式设备，查看视图并找出隐含的信息。
自然地，可以提出以下问题：
- 这个分析场景适合什么样的数据场景/问题场景？
- 为什么这样的设计更好？如何评估不同设计的表现？
- 如何改善当前系统的表现？
我们把问题归纳一下，形成四个主要的类型：
- 视觉设计问题，解决“最适合当前场合的设计”，以及“不同设计的优劣”；
- 交互设计问题，解决“最适合的输入输出手段”；
- 评估问题，解决“如何评价或衡量视图/交互/可视分析系统的表现”；
- 场景问题，解决“不同设计的适应场景”。
详细而言…
根据上一节提出的问题，我们可以继续细化出这些问题的相关因素：
比如：
背景环境是否产生影响？

视图设计中应该考虑什么因素（尺寸、形态、颜色、布局等）？

使用什么交互？

如何改进协作分析流程？

使用新型设备（如AR眼镜）是否影响了用户表现？
新颖的设备一定好吗？新设备普遍地增强了大多数用户的表现，还是对特定人群更有效？

VR与AR，应该用哪个？
