Read the bible from a chip on with my app (ReactNative)

OCR to find specific symbols and move you to the right chapter of the bible. The bible is written on a small chip. We have a microscope which is being attached to the rear camera. When u open the camera you see small fonts of the bible. In case you recognize a specific symbol (triangle) than u know what chapter to open in the application. The whole bible is being written in the application (text format). Bible can be found here: [login to view URL]://www.gasl.org/refbib/Bible_King_James_Version.pdf&ved=2ahUKEwiir-vH7L7sAhWlx4UKHV7eBMEQFjABegQIChAB&usg The chip contains 1000 rectangles and each rectangle includes few chapters. On each rectangle we will have 5 symbols like "A" letter. The symbols are like bits. 4 bits for each symbols (up, right, down, left). Up, up, up, up, left means 00003 (index 3). We will have a mapping table that index 3 equals to chapter 41. Than u move the application to show chapter 41.
