We introduce a new Passive Refreshable Tactile (PRET) Printer concept. Using off-the-shelf components of a laser engraver and the nascent Tacilia technology, the prototype enables the creation of refreshable tactile graphics. By leveraging Pixel Art as a rendering process, we enhance the diversity of image production on this medium. We contribute technical specifications, open-source files to make the PRET printer and a qualitative evaluation of the concept by tactile learners. The prototype facilitates rapid and cost-effective development of refreshable tactile media, crucial for improving comprehension. The work builds upon existing research, furthering the groundwork to address the needs of tactile learners worldwide and establishing a foundation for further innovation and development in this domain. date: 2024 date_type: published publisher: ACM (Association for Computing Machinery) official_url: http://dx.doi.org/10.1145/3674829.3675070 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2311935 doi: 10.1145/3674829.3675070 isbn_13: 979-8-4007-1048-3 lyricists_name: Holloway, Catherine lyricists_name: Bhatnagar, Tigmanshu lyricists_id: CSHOL54 lyricists_id: TBHAT16 actors_name: Bhatnagar, Tigmanshu actors_id: TBHAT16 actors_role: owner full_text_status: public pres_type: paper publication: Proceedings of the 7th ACM SIGCAS/SIGCHI Conference on Computing and Sustainable Societies pagerange: 156-166 event_title: COMPASS '24: ACM SIGCAS/SIGCHI Conference on Computing and Sustainable Societies book_title: Proceedings of the 7th ACM SIGCAS/SIGCHI Conference on Computing and Sustainable Societies citation: Bhatnagar, Tigmanshu; Holloway, Catherine; (2024) PRET Printer: Development and Evaluation of a Passive Refreshable Tactile Printer.
