3D printing for accessible graphics – project updates

Please check back regularly for monthly updates.

Progress made

October 2018

October 2018 marked the beginning of the three-year project investigating the use of 3D printing for access to graphics by people who are blind or have low vision.

Standards: A shared document was created on Google Drive with tips and tricks for printing for accessibility. This is a working document that will be continually added to throughout the project. It is not yet ready for release but please contact leona.holloway@monash.edu if you would like access to evaluate or add to the document.

November 2018

Mapping: Work commenced on creating TinkerCAD components for modelling street crossings.

Standards: Began modelling of 3D-printable textures.

3D printed textures - short raised lines, domes and flat dots

Administration: The first meeting held with the project’s expert advisory group. The project team is joined by representatives from partner organisations (the Department of Education and Training, Round Table on Information Access for People with Print Disabilities, Guide Dogs Victoria, the Royal Society for the Blind) and peak organisations from the print accessibility sector (Vision Australia, Blind Citizens Australia, Queensland Tactual Mapping Committee). Meetings will be held quarterly in March, June, September and December.

December 2018

3D printed braille swing cell with removable rods for the braille dotsTactile Literacy: Face-to-face brainstorming meetings were held with production and teaching staff at RIDBC and SVRC. Some of the main areas they suggested where 3D printing could assist in tactile literacy:

  • Braille swing cell
  • Braille games
  • 3D shapes – solid, cross-sections and nets
  • Games matching 3D objects with tactile graphics

January 2019

Collaboration: Research Assistant for the project, Leona Holloway, joined the DIAGRAM working group on 3D tactile standard. The group meets fortnightly and has a focus on 3D printing for education for students with vision impairments.

How many cylinders are there in the cat?

Tactile Literacy: We conducted our first school visit, discussing the materials required for touch readers in their first years of primary schooling. Suggested materials included:

  • tens frame for placing counters
  • MAB blocks with outward-facing lines
  • braille number line
  • fun “find the shape” activities

March 2019

Administration: The project’s expert advisory group met for the second time. Bruce Maguire joined the group on behalf of Vision Australia.

Map of Carlton Gardens with felt grass, a 3D printed building and fountain, and 3D printed icons for food, drinks, etc. Mapping: “Immerse Your Senses” was the theme of the 2019 Melbourne International Flower and Garden Show,  held at the Carlton Gardens from Wednesday 27 to Sunday 31 March. We created an accessible map of the Show with 3D-printed icons, along with handheld models of the Rob Waddell Show Garden and Guide Dog Victoria’s sensory garden. Over the course of the event, we collected feedback on the maps from 10 visitors who are blind or have low vision.

April 2019

Mapping: Throughout April we focused on analysing the results from the mapping study run at the Melbourne International Flower and Garden Show in March and writing a paper for an international conference submission. We were also busy preparing materials for the mapping workshop in May.

May 2019

Collaboration: The Round Table on Information Access for People with Print Disabilities Inc. is a major project partner. Their annual Round Table Conference for 2019 was held in Brisbane with the theme “The Changing Landscape for Accessible Information”. On Sunday 5 May, project Chief Investigator Matt Butler of Monash University delivered a feature presentation about the project entitled “Partnering for Progress”.

Mapping: On Monday 7 May, Leona Holloway and Matt Butler (Monash University),  Tony Starkey (Royal Society for the Blind) and John-Ross Barresi (Guide Dogs Victoria) presented a hands-on workshop demonstrating a collection of 3D-printed maps of the Round Table Conference location and surrounds. Approximately 70 people were in attendance, providing feedback from their perspective as touch readers, accessible formats producers, teachers, O&M instructors and technology providers.

Guidelines: Work continues on creating a variety of textures that can be incorporated into 3D prints. At a SensiLab Open House evening, we trialled a “mystery box” activity asking people to find matching textures by touch. It was a surprisingly difficult task! This activity will be extended for more formal trials and the upcoming Extrasensory evening as part of National Science Week.

Tactile Literacy: We have started collecting and designing 3D materials to support vision impaired students in their first year of schooling. These materials include: braille swing cell; braille fidget cube; braille word cubeMAB blocks; tens frame; number lines; fraction pies; tactile coin for flipping; braille dice; tactile dominoestangram puzzle; 3D shapes with equal volume; tactile ruler; 3D maps of familiar places; data grid. Please let us know of any further materials you think would be useful at this level.

June and July 2019

Administration: The project’s expert advisory group met for the third time in June.

Collaboration and Promotion: On Thursday June 20, Matt Butler spoke about the ARC Linkage Project and 3D printing for tactile literacy at VISCON in Sydney. VISCON is a two day biennial conference for educators and related specialists in education for children who are blind or have low vision.

Tactile Literacy: A survey on tactile materials for the classroom is ready for distribution.

Mapping: We toured two schools for which 3D maps will created for use by students beginning there in 2020.

Guidelines: A selection of 50 textures were designed and printed for testing in a series of tactual discrimination tasks.

Planned events

National Science Week – 10 August 2019

Extrasensory. National Science Week 2019. See, hear, smell, taste, feel, more!Standards and Promotion: We have been invited to participate at ExtraSensory, Melbourne’s premier National Science Week event to be held at Parliament House from 6-10pm on the 10th of August. We plan to host a series of tactile games allowing us to collect data about tactile discrimination of 3D printed textures and symbols.Tickets for this special event can be purchased from https://extrasensory.eventbrite.com.au/.

ACM SIGACCESS Conference on Computers and Accessibility – October 2019

Promotion: ASSETS is the premier forum for presenting research on the design, evaluation, use, and education related to computing for people with disabilities and older adults. We will be attending this international Conference to present our work on 3D printing for mapping from the Melbourne International Flower and Garden Show.

SPEVI Conference – January 2020

Collaboration and Promotion: The next biennial conference of the South Pacific Educators in Vision Impairment (SPEVI) will be held in Adelaide in January 2020. We have submitted proposals for a talk, workshop and poster to share our work to date on the use of 3D printing for education.
