  This paper presents a systematic literature review of 292 publications from
97 unique venues on touch-based graphics for people who are blind or have low
vision, from 2010 to mid-2020. It is the first review of its kind on
touch-based accessible graphics. It is timely because it allows us to assess
the impact of new technologies such as commodity 3D printing and low-cost
electronics on the production and presentation of accessible graphics. As
expected our review shows an increase in publications from 2014 that we can
attribute to these developments. It also reveals the need to: broaden
application areas, especially to the workplace; broaden end-user participation
throughout the full design process; and conduct more in situ evaluation. This
work is linked to an online living resource to be shared with the wider
community.
