Hi Jenny. I found the Look Tell Recognizer to be the easiest bar code app for me. It doesn't seem to be as much of a pain as the other one I had which you had to b" sighted or lucky to use.

After double tapping the "Text" button (Step 1) and before >> double tapping the "Camera" button (Step 2), place your iPhone on the page >> you want to OCR using the edges of the paper to align the sides of the >> device. Center the iPhone so that the camera lens (top right corner as you >> normally hold the device) is approximately in the center of the page. (If >> you use a case, make sure that the back of the case does not block the >> camera lens). Sandy has mentioned suggestions like lightly folding the page >> in half length-wise and width-wise to guide positioning and aligning the >> iPhone, in the case of practicing with a sheet of letter paper.

(Nine inches is roughly twice the length of >> the iPhone.) You'll feel the iPhone vibrate, and then VoiceOver will >> announce "auto-focused". At this point you can say "Take Picture" and hear >> the shutter close. (You'll probably start by lifting the iPhone too slowly >> to reach 7-9 inches before you feel the vibration and hear "auto focused". >> Say "Take Picture" anyway -- your image is more likely to be in focus. The >> actual distance you lift depends on the size of the page. Small billings >> only require about 6 or 7 inches. I practice lifting and then check the >> distance I've lifted an iPhone against the handspan of one hand, which for >> me is 7 inches, but I have small hands. >> 6) Double tap the "Use" button in the bottom right corner of the screen. >> This is the last element on the screen, so you can also just use a four >> finger tap on the bottom of the screen and then double tap. (I preferred >> the four finger swipe down, but this is the current gesture for moving tot >> he end of the screen.) >> 7) On the next screen flick right the "Next" button in the top right corner >> and double tap. You'll move to a screen labeled "Processing" >> 8) The results of the OCR will show up in an "Edit" screen which will let >> you review and edit your results. >> 9) Double tap the "Next" button in the top right corner when done. You can >> Save your results, or copy them, mail or upload them. Options such as copy >> or email are listed as buttons along the bottom of the screen.
