This paper describes the creation of a low-cost Braille printer using readily available components and open-source software. Existing Braille printers are expensive for many visually impaired individuals, particularly those with limited economic resources. This project aims to address this issue by providing both a fun...
The study did not include learners with visual impairment, Braille teachers, rehabilitation specialists, or other end users, and it did not collect quantitative measures of accuracy across the full character set, writing speed, embossing quality, latency, durability, safety, and user satisfaction.
University technology campuses contain specialized laboratories, academic programs, and services that can be difficult for first-time visitors to identify. This paper presents INDI, a custom mobile campus guide robot that combines spoken interaction, synthesized speech, touchscreen feedback, animated facial states, hea...
We present the NeuralNexus Arm, an open, low-cost 6-DOF robotic manipulator built by an undergraduate engineering team, together with the design decisions and debugging experience needed to reproduce it. The arm is driven by a single STM32H743 microcontroller on a custom printed circuit board (PCB) and combines two ste...
Electronic Braille notetakers can support independent reading and writing, but their interaction logic must coordinate chorded input, refreshable output, file operations, cursor feedback, and audio prompts within a compact device. This paper presents the design and functional validation of a Raspberry Pi 4-based Grade...
Tact, a browser-based pipeline that converts a spoken or typed story idea into printable braille with a matching raised tactile illustration, without an account or mandatory cost and with an offline-capable path is presented.
