About OCR Test - Works offline
Experimental app for optical character recognition (OCR)
Runs the Tesseract OCR engine to find text in images captured by the device camera.
This app runs OCR on your device--without uploading your images to a server--and is suitable for recognizing individual words or short phrases of text.
The default single-shot capture runs OCR on a snapshot image that's captured when you click the shutter button, like a regular photo.
When the "continuous preview" checkbox is checked, the app shows a dynamic, real-time display of what the device is recognizing right beside the camera viewfinder. The continuous preview mode works best on a fast device.
USING THIS APP
• Point the device at a small region of text and touch the on-screen shutter button to start OCR.
• For recognizing individual Chinese/Japanese/Korean characters, set the page segmentation mode to "single character."
RECOGNITION ACCURACY
• Various factors can cause the OCR to fail: uneven illumination, stylized text, or text without enough contrast from the background. Try to have good lighting.
• Hold the device steady, and be sure the picture is in focus.
• If you need to scan a large block of text or an entire document, try a document scanning app such as Text Fairy instead.

This is a great start, and the offline approach is definitely the way to go. What would really push it upu a notch woulod be the ability to link to an offline dictionary for the translation, instead of using the online google or bing translation options.

Once improved, it will be great tool for language learners. No need to go back and forth while reading. It would be great if it had history. Also need to link thesaurus dictionary.
