Hi Jenny,

In practice the Prizmo program is not complicated to use. The actual sequence 
of gestures are:
1) Open the app and flick right to "Text", which is the first listed source 
type, and double tap
2) On the next page, flick right to the "Camera" button and double tap
3) If you want to use the new iOS 5 feature of taking a picture by pressing the 
volume up button, you don't need to do any set up, and when you're on the 
"Camera" screen you only need to center the iPhone's camera on the page -- 
which means putting the top right corner in the center -- and lift the iPhone 
about seven inches from the page, listening for when you hear "autofocused".  
If you don't turn on the speech control, you'll hear everything at normal 
volume.
4) When you've lifted the iPhone to a height around 7 inches above a standard 
letter sheet, press the volume up button on the side, taking care to hold the 
iPhone as steady as possible while you hear the shutter click. This is the 
stage at which using the speech control can improve results, because in most 
instances tapping buttons on the screen introduces a slight motion and blurring 
when the picture is taken. It's a bit easier to do this without motion shake 
using the volume control to take a picture under iOS 5.  The other way to do 
this and minimize motion shake without using speech control  by saying "Take 
Picture" is to put one finger on the "Take Picture" button just above the 
"Home" button on the "Camera" screen just before you lift the iPhone. Try to 
hold things steady when you've lifted the phone to seven inches, and gently tap 
another finger on the screen to activate this button with a split tap gesture.
5) Flick to the "Use" button or just touch it in the bottom right corner of the 
screen and double tap.  This is also the last element on the screen, so you can 
alternatively use a four finger tap on the bottom of the screen to navigate to 
this button.
6) Flick to the "Next" button (top right corner) and double tap
7) Wait for the "Processing" message to finish, and for "Edit" screen to be 
announced.  You can read the OCR results from this screen.  If you want to edit 
to make corrections, double tap in the text area and make changes. Double tap 
the "Done" button at the top right corner, which will turn in to a "Next" 
button. Then double tap the "Next" button (top right corner).
8) At the bottom of the "Text" screen are option buttons  to "Copy" or "Mail" 
among other things. Flick to the one you want and double tap.  I usually don't 
bother to save the results within the Prizmo app, but you can do so by double 
tapping the "Save" button at the top right corner.

Notice that most of the length in these instructions involve explanations of 
different options (in step 4) and what other buttons do.  Prizmo actually gives 
full instructions at their web site, but they're visually oriented.  My 
original description that Anne quoted is long, because it also explains control 
options like how to set up OCR for different languages.  For English, all you 
have to do after taking the picture and double tapping "Use" is to keep double 
tapping the "Next" button in the top right corner until you want to mail or 
copy the results.

Also, you don't have to use the Light Detector app.  I just take it out and pan 
across the page to check the volume level before I use Prizmo.  That's it.

HTH.  Cheers,

Esther

>> left corner), you can start the process again, with your headphones 
>> connected.  After double tapping the "Text" button (Step 1) and before

>> that you flatten the paper because failing to keep either the page or the 
>> iPhone flat when you take the picture will cause some of the letters to show 
>> up as tildes; this is typical if you scan a book page and haven't flattened 
>> the section near the spine enough.
>> 5) Double tap or split tap the "Camera" button, then, using two hands to 
>> make sure you keep the iPhone level, raise it steadily up from the page to a 
>> height of about 7 to 9 inches. (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

>> 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.  Do a three 
>> finger flick left to hear the second page of options, which include 
>> MobileMe, DropBox, etc.
