I'd like to be able to analyze an image captured with the iPhone camera and generate survey results (multiple choice). Apparently what I'm interested in is called OMR, Optical Mark Recognition (not OCR, Optical Character Recognition which is more sophisticated).
Does anyone know of any OMR libraries or source code that can be used to build such an iPhone app? And if not, any suggestions on rolling my own would be appreciated. Thanks for the help in advance.
Maybe this is of interest to you:

It's from the developer of Sudoku Grab, which recognizes sudoku grids from the camera. It should definitely be useful to you.

I want to build an app that recognizes sounds like whistle and other non speech sounds.
So when someone whistles, method is called or something happens.
Is there any API for that?
I searched a lot but I couldn't find anything.
Try the following guides:

Detecting a clap in IOS
Essentially you can use the AVAudioRecorder class that does the job for you.

I am trying to use Video.JS in an environment that requires ADA Compliance. Part of this is the capability to tab through and activate all video controls in both Flash and HTML5 versions of the player. The performance of the built-in tabbing of Video.JS is pretty buggy, especially in Flash. I am hoping to get my hands on the FLA and source code of the Video.JS flash player so I can tweak the tabbing behavior. Does anybody have any idea where I could find it?
Thanks!
The source for the swf component is on Github: https://github.com/zencoder/video-js-swf

Is there any open source code for creating a piano keyboard with sounds for ios? I have looked but have not found one, or offer a good recommendation were to start, AVAudioPlayer. or systemSoundID
Here is one you can try. It is something I started a while back and have not had time to finish because of my day job.
https://github.com/yepher/MusicNotes
I found this great tutorial, it is a little advanced but perfect for learning. I already have a simple version up and running using this tutorial
http://mobile.tutsplus.com/tutorials/iphone/ios-sdk_playing-systemsoundid/
I have tried a few solutions, and eventually used this piano keyboard for iOS, since I couldn't get rid of the lag which is crucial when using it as part of a multitracker for timing issues (an app I'm working on).
I learned a lot from going over the code and through the support I got from the author, so even though it wasn't free I was very pleased with it.

I am planning to give a demo of my app to my clients.For that purpose i want to share my screen with the other Ipads say there will be 5 Ipads among the clients and i want to share my screen with them.
Is there any way to do that?Can anyone post something which will help me?
Thanks in advance,
Christy
There is no app which allows for mirroring the whole iPad screen. All screen sharing apps, that currently exist mirror the content of the screensharing app, but nothing else.
No workaround, I am afraid.
