Tactile Literacy: In collaboration with accessible formats producers at the Statewide Vision Resource Centre and RIDBC, we continue to build the ANZAGG collection on Thingiverse with free 3D models for educational use.
Mapping: While the first map is in testing with Guide Dogs Victoria, we produced a second 3D printed map of a school building. This is our first exploration of how to represent multi-level buildings.
Tactile Literacy: We attended the Statewide Vision Resource Centre Tech Expo, where we presented a workshop on 3D printed materials for early learners and invited vision specialist teachers to take part in our survey at accessiblegraphics.org/2019/12/18/survey/. This survey is open to all people working with vision impaired children in prep to year 2. Your input is vital to help shape our research, guidelines and design of materials.
Guidelines: We have commenced extending our work on designing and evaluating 3D printed textures for tactual discrimination.
Promotion: Many of the models that we have identified or designed for touch readers are available for free download from the ANZAGG Thingiverse collection under the auspices of Round Table’s Australia & New Zealand Accessible Graphics Group. These materials have now been included in the meta-library of tactile graphics and 3D models by BTactile.com.
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 attended this international conference to present a paper on 3D printing for mapping from the Melbourne International Flower and Garden Show, along with a poster on accessible formats (including 3D printing) for access to art, as explored with Bendigo Art Gallery.
Promotion: As part of Diversity and Inclusion Week, SensiLab hosted a showcase of projects by Monash University’s Inclusive Technologies research group, including our work investigating 3D printing for accessibility.

Mapping: We produced 3D printed maps of a school ground and classrooms. These maps will be used by a student starting at the school in 2020 with assistance from their O&M instructor. Feedback will help inform design of further maps.
Promotion: As part of National Science Week, we were invited to take part in an event at Parliament of Victoria with the theme “ExtraSensory”. We hosted a room in which we had activities relating to 3D printed icons for tactile maps and tactile discrimination of 3D printed textures. The event attracted over 1,000 visitors with whom we were able to speak about our research and the importance of accessibility.
Guidelines: The “ExtraSensory” event provided a perfect opportunity to collect a large amount of data to assist in the identification of a range of 3D printed textures that are tactually distinct from one another and suitable for use on accessible maps and learning objects.
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.

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 cube; MAB blocks; tens frame; number lines; fraction pies; tactile coin for flipping; braille dice; tactile dominoes; tangram 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.

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

Tactile 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
Mapping: Work commenced on creating TinkerCAD components for modelling street crossings.
Standards: Began modelling of 3D-printable textures.
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.
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 firstname.lastname@example.org if you would like access to evaluate or add to the document.
