“…Beberapa teknologi yang dapat membantu tunanetra seperti Perangkat yang menerjemahkan teks ke audio, keyboard yang diadaptasi ke braille, pencetakan 3d yang berasal dari buku, kacamata pintar , aplikasi seluler, buku audio, pembaca layar, keyboard dan lainnya. Teknologi-teknologi tersebut memiliki beberapa kekurangan, yaitu biaya yang cukup besar, kurangnya pelatihan terhadap teknologi tersebut, dan masih dalam masa percobaan (Apurva et al, 2017;Encinas et al, 2019).…”

Keterbatasan penglihatan pada tunanetra berdampak pada kehilangan informasi tentang apapun yang bersifat visual seperti ketidakmampuan dalam membaca buku-buku biasa atau buku-buku dengan tulisan awas. Printer Penerjemah Teks ke Audio-Braille atau PRIPEN TAB dirancang untuk dapat membantu tunanetra dalam memperoleh informasi melalui buku-buku dengan tulisan awas. Metode yang digunakan dalam penelitian ini ialah penelitian pengembangan atau Research and Development. Model pengembangan yang digunakan ialah Model ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Dengan adanya PRIPEN TAB akan sangat membantu tunanetra dalam memperoleh informasi melalui buku-buku dengan tulisan awas tanpa bantuan orang lain, membantu guru dalam membuat bahan ajar braille demi menunjang pembelajaran tunanetra di sekolah.

“…Unlike tactile electronic interfaces, this method consists on embossing dots permanently on paper. Duran and colleagues implemented a single hammer mounted in a two-axis platform [26]. When actuated, the hammer stamps a mark on the paper.…”

Design and Implementation of a Low-Cost Printer Head for Embossing Braille Dots on Paper

This paper presents the design, implementation, and prototype of a low-cost Braille embossing mechanism. The proposal is a printer head integrating three hammers that, upon actuation, stamp readable dots on the paper. Inspired in the rotary cam-follower mechanism, the hammers are actuated by a single servomotor which rotation determines which hammer strikes the paper. Braille characters can be quickly embossed using the proposed printer head. Affordable and efficient Braille embossers for home use can be envisaged using this new action approach.

This paper reports on the progress of a wearable assistive technology (AT) device designed to enhance the independent, safe, and efficient mobility of blind and visually impaired pedestrians in outdoor environments. Such device exploits the smartphone’s positioning and computing capabilities to locate and guide users along urban settings. The necessary navigation instructions to reach a destination are encoded as vibrating patterns which are conveyed to the user via a foot-placed tactile interface. To determine the performance of the proposed AT device, two user experiments were conducted. The first one requested a group of 20 voluntary normally sighted subjects to recognize the feedback provided by the tactile-foot interface. The results showed recognition rates over 93%. The second experiment involved two blind voluntary subjects which were assisted to find target destinations along public urban pathways. Results show that the subjects successfully accomplished the task and suggest that blind and visually impaired pedestrians might find the AT device and its concept approach useful, friendly, fast to master, and easy to use.
