  Refreshable tactile displays (RTDs) are predicted to soon become a viable
option for the provision of accessible graphics for people who are blind or
have low vision (BLV). This new technology for the tactile display of braille
and graphics, usually using raised pins, makes it easier to generate and access
a large number of graphics. However, it differs from existing tactile graphics
in terms of scale, height and fidelity. Here, we share the perspectives of four
key stakeholders -- blind touch readers, vision specialist teachers, accessible
format producers and assistive technology providers -- to explore the potential
uses, advantages and needs relating to the introduction of RTDs. We also
provide advice on what role the data visualisation community can take to help
ensure that people who are BLV are best able to benefit from the introduction
of affordable RTDs.
