One sentence summary
 Understand how math augmentation (maugs) enhance readability of formulas, and how future authoring tools could help authors create augmented notation.

Motivation
 The challenge of making mathematical notation more understandable

Gap
 this paper is to review the practice of math augmentation in order to inform the design of tools of each of these types for math notation

Research Questions
 1. How do authors augment notation to improve its readability?
 2. How can authoring tools help authors augment notation in the ways that they wish to more easily?

Method
 1. Content analysis
 2. Interview Study
 two qualitative studies

All the takeaways

1. Augmentation practice
 1.1 Benefit in improving engagement
 1.2 16 kinds of maugs were observed, belonging to the categories of visual notation, style, annotation, and interactivity.

2. Authorsâ€™ Tool
 2.1 Challenge of current tool (timeconsuming, limitation of the static media, hard to introduce complex formulas, LaTaX was hard to use)

2.2 The design of future tools for presenting math notation
  Nextgeneration markup languages
  Graphical editors
  Intelligent design assistants
 3. Insights into authoring practice, knowing their preference and the challenges they face.
