Create an OCR app that can read braille symbols and convert it to vibration patterns.

I got this inspiration after reading this article.

It would be great if we could leverage machine learning/deep learning or other AI algorithms to detect the symbols and then convert it to vibration patterns.

The issue describes a high-level concept for an OCR app that reads braille and converts to vibration patterns. No specific files, tests, or implementation details are provided. Research would start by exploring the existing Android app codebase to understand its structure, then investigate machine learning libraries for braille symbol detection and Android's vibration API. The scope is large and undefined, requiring significant design work.
