Create an app that detects text in an image and converts it to vibration pattern of braille.

这个 Issue 没有描述。

The issue is a broad feature request with no implementation details. A newcomer would need to research Android camera APIs, OCR libraries like Tesseract or ML Kit, and how to map text to Braille vibration patterns. Start by exploring the existing app structure to see how voice and vibration feedback are implemented. 'Done' means a working prototype that captures an image, extracts text, and outputs a corresponding vibration sequence.
