OCR detection

[Petr Kirpeit]

Hello,

Im new here and I have a question about OCR detection.

I would like to create a easy App.

I want Open the camera and scan a word/ Value, open the Webviewer and search it on Google or a other search engine,

I want to make my work easier, because I need mostly datasheets to some electronic elements and dont want type all.

Hope someone can help me :)

thanks

but I want that this what the App scanned and OCR detected get as a search answer

App Inventor does not have a scan OCR capability.    To do something like that you may need to program in Java with Android Studio and use an OCR library ...see this stuff:  https://www.google.com/search?q=android+studio+ocr&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=fflb 

App Inventor can take a picture but it can not determine the words that would be captured and in turn search.   To search using App Inventor, you can use the Activity.Starter

.

Launch a Web search

To launch a Web search for a particular query, such as "Homer Simpson", use an activity starter with these properties:

Action: android.intent.action.WEB_SEARCH
ExtraKey: query
ExtraValue: Homer Simpson
ActivityPackage: com.google.android.providers.enhancedgooglesearch
ActivityClass: com.google.android.providers.enhancedgooglesearch.Launcher

My experience is that you should not use the ActivityPacage or ActivityClass .. leave them blank.    It seems the device can find these values on its own   and following the total directions here might not work on some devices.

Regards,
Steve

Oh I see, well it were great if they would insert a open source library into the MIT AppInventor.

Do you know a App or a plugin to share something to Google search?

Because the App https://play.google.com/store/apps/details?id=co.kr.generic.ocr

I can scan it and share it to some Apps, so it were great if I can share it to the google search

do you have a idea?

[SteveJG]

App Inventor OpenSource is here:   http://appinventor.mit.edu/appinventor-sources/  

To do a Google search from AI2, you use the Activity.Starter as I mentioned in my previous post

You might also be able to bring up the OCR apps you found using Activity.Starter ...

How you use the second app to grab text and use with an AI2 app might be possible but I have no clue.    Look for ideas here:

http://ai2.appinventor.mit.edu/reference/other/activitystarter.html     which explains how to use it.    

Can it be done?     I have no idea although if you know the right keywords to plug into activity.starter, you might be the first.

If you figure it out, please post here and explain how you did it.   Thanks.

Regards,

Steve

If you want easy, try the Google Goggles app.
It will scan and search.

@Abraham Getzler,

that dont do what I want, it can scan only QR- or Barcodes, but not OCR detection, I want open the camera and OCR a title/value which stand on the paper and so that I can get the value in a google search.

what about using an API?

for example this one http://www.ocr-it.com/ocr-cloud-2-0-api

Yeah I see,

But Im not so in this, and I dont have alot time to learn how to use this all in a App.

[Taifun]

I could set up a new tutorial for this
