Making an OCR APP

I want to make an Optical Image Recognition app with the help of App Inventor.
The app would :
1) Take a picture from the camera
2) Recognise the text written on it.
3) Read it aloud.

The app is being developed especially for the visually challenged.Please guide me as soon as possible.



OCR the way you describe is not possible with App Inventor.   There is a commercial web page that will take images and 'read' words but AI2 can not do this.

Here may be a way to do this, but you probably will need to use an Eclipse or Android Studio compiler:  http://stackoverflow.com/questions/19533273/best-ocr-optical-character-recognition-example-in-android

you can do it with App Inventor and an OCR API

Attached you can find an example aia project, which uses ocr-it.com

I abandoned that project, because it takes around 2-3 minutes until you get the result back from the API...

see their subscription plans and pricing here http://www.ocr-it.com/ocr-cloud-2-0-api-subscription-plans-pricing

steps for the example:

1. upload your picture to your web server, I used this method https://puravidaapps.com/postfile.php

2. send the link of the uploaded image to the ocr-it API

3. check, if the result is already available (it will take a while, drink a coffee meanwhile...) 

4. if result is available, display it

if you want to use the example, get your own secret key here http://www.ocr-it.com/free-ocr-cloud-2-0-api-trial and follow my tutorial to upload a file to your web server https://puravidaapps.com/postfile.php

PS: you can try to find another OCR API (probably a faster one) here http://www.programmableweb.com/search/ocr
