Prototype Multi-Sensory Braille Device
Budget: $15 – $25 USD
I already hold a fully documented concept for a multi-sensory interactive device that will pair with an upcoming mobile app for people with visual impairment. All design drawings, block diagrams, and a step-by-step development roadmap are ready; I now need a skilled engineer or small team to turn the hardware portion into a working prototype.
Where I’d like you to start
• Multi-sensory device development is the immediate priority.
• Core features to implement from day one:
‑ Enhanced audio feedback delivered through quality onboard speakers or bone-conduction drivers.
‑ Braille support tools featuring:
• Text-to-Braille conversion in real time
• Braille-based input keys/cells for navigation and data entry
• Precise haptic feedback for confirmations and alerts
Project scope
1. Review my schematics and component suggestions, then refine them for manufacturability and cost.
2. Produce detailed electronic schematics, PCB layout, and a complete bill of materials.
3. Develop firmware that drives the audio engine, Braille cells, and sensor suite while leaving clean hooks for the future mobile-app integration.
4. Assemble and test a functional prototype, validating tactile accuracy, latency, and audio clarity against the provided acceptance criteria.
5. Deliver build instructions, source code, and test reports so the design can move straight into small-batch production or further iteration.
I have included high-level system drawings and a full development guide; you’ll be free to suggest component substitutions or architecture tweaks that improve reliability or lower cost without compromising accessibility.
If you have proven experience with assistive technology, haptics, embedded C/C++, or audio DSP, I’d love to hear how you would tackle this challenge and what similar products you’ve shipped. Let’s build something that truly empowers the visually impaired community.
