When reading a book or magazine with OCR, what is the usual (or suggested) distance between book and iPhone? I'm merely looking for a ballpark figure; a distance most people feel comfortable with.
FWIW, I'd say that mostly depends on the size of the font in the book you're reading, and on how steadily you can hold your phone (steadier -> able to keep it pointed at text with a larger zoom factor -> farther away).

Good question, but I was thinking end of the file. Basically, I want to be able to check the recognizer's work, since some people claim still image rec is potentially unreliable. I guess this will need three panes, one for the HWR for correcting the text in question. (Of course, if there's a Mac version I could just use that for this kind of translation.) Using an iPhone as a HWR input device for the iPad would be helpful here.
Makes sense. Quite well aware of your interest in using an iPhone for iPad handwriting input
Entropy said:
Huh. So it does. But it also gets Western characters from adjacent lines. I guess you could filter them out when the text is actually captured, rather than in the recognizer.
I suppose, but the presence of Western characters might make it easier to quickly spot a mis-recognized line... I don't see much benefit to skipping them, anyway, it's rare that you'd have a mis-recognized document where the mis-recognized bits exclusively took the form of out-of-place A-Z letters and there weren't also few stray Chinese characters mixed in. (heck, even when recognizing English text the system sometimes has a tendency to misinterpret a few of them as Chinese characters)
Entropy said:
But the killer feature will be to figure out how to let me write on one input device while using my computer normally in every other way. If you can do that, you could also let me attach a second keyboard for pinyin input.
That would be the benefit to the iPhone-as-external-Mac-input-device, I suppose, though the other app that did that with the iPhone's built-in recognizer doesn't seem to have done very well.
Entropy said:
I turned this up to 5 in the live mode and it seems much nicer now. (Also turned it up in the other modes.) It's still plenty responsive. BTW, it might be nice to have a mode that shows pinyin in place of the definition.
OK, we might want to consider increasing the default... and only Pinyin, no definition? I guess it would be a bridge to reading Chinese for people who were better on spoken Chinese than on characters, though we'd have to accept a certain degree of inaccuracy in ambiguous cases (multiple pronunciations / meanings for the same character, with the definition the easiest way to disambiguate).
Entropy said:
That wasn't meant as a complaint. I think they'd be easy enough to hit even if there were 4 instead of 3--I want to capture the very text I'm currently reading (the whole text--capturing a flashcard while in pause mode would presumably only add the first word.) And, in pause mode I want to be able to tap a character or word and perform all the usual actions, as if i were in the reader.
Maybe we could have three little tabs on the side like we do in flashcards?
Entropy said:
5 buttons might be too much, I have go admit. But if I capture text, I can presumably make flashcards later, so that seems like the obvious choice. Anyway, why not just tap anywhere on the screen to pause/capture/&c? Or, tap (two-finger tap?) on the screen to move to the next word in a block of live text.
We actually did have people tap on the screen to pause capture in Beta 1, but we changed it because it was making it too difficult to resize the box - now we have extremely generous tap areas for the box corners, you can touch almost everywhere and have it anchor your touch to the nearest dot.
Entropy said:
BTW, I think that "Docs+OCR" would be better than "Read+OCR" since the documentation is there. And, the manual should be downloaded by the app so it's available offline, at least when you purchase and download another add-on.
That might make it harder to find the reader, though - we really need a way to label all three. Though if we replace the tab bar with a screen that contains more icons (an idea I'm liking more and more) we can fix the problem easily that way by not combining too many things into each tab.
The manual already can be downloaded for offline use, see the "Free" tab in Add-ons. (new feature in 2.2)

I think it was basically a bug. Even though I said above that it could be partially intensified by a network problem, well, usually, when a network is inaccessible, we see that "rotating asterisks" or whatever it is called, indicating that something is going on, and then after a while an error message is displayed. But in my case, everything just froze.
That's odd... basically all we do is tell iTunes the user has initiated a purchase and then put up that spinning icon until it responds, so it seems like it must have frozen in the middle of that initiate-purchase command. Could be an Apple bug, actually, the OCR bug on 3GSes running 4.2 took exactly that form (call into an Apple function that's supposed to run in the background and it hangs). I suspect they've been busily updating different parts of iOS to improve its multitasking support, in anticipation of the arrival of dual-core mobile processors in 2011 - problems like that are far and away the most common / infuriating type of bug in multithreaded programming.

As for the OCR itself, I agree with the user "nihao pengyou" here, that after our expectations were set so low before, the actual performance is really impressive. For me, it worked very nice with subtitles, you just have to get used to it a little bit. It has problems when subtitles are shown over a heterogeneous, speckled background or when the character looks "out of focus" by itself already, when you can hardly see the spaces between the strokes. But I would never expect any OCR program to be any good under such circumstances! But otherwise, the OCR proved to be very effective with subtitles. Sometimes, I was even quite surprised that the OCR recognized the characters correctly even though they looked pretty fuzzy to me. When I looked closer, I realized that the fuzziness was caused by a rather strong gradient in the color intensity along the width of the stroke. Apparently, it was not a problem for the OCR as long as the spaces between the strokes remained clear.
All in all, the overall impression is very positive, it seems to be a very useful new tool even on an "unsupported" iPod Touch. Thanks guys!
Great! It's sounding more and more like we want to change this from totally unofficial to semi-official - still require jumping through a few more hoops, but maybe not be quite as discouraging of it as we are now. (I'll have to do a database check in a few days to see what percentage of people activating their iPods to enable OCR actually ended up purchasing it)

Hello Mike,
I just purchased the complete bundle for iOS, but the OCR add-on does not appear as an add-on which I am able to download and purchase.
I have an Iphone 4 that is running on a China Unicom contract in mainland China. Could that have sth to do with it, or the fact that i am seeking to purchase it within the Mainland .... or that the phone itself somehow does not allow me to download the OCR, because it is linked to a specific carrier, or problems with Itunes for purchases from within China?...can't seem to figure it out
Just seems odd and I really would like the OCR feature...one of my key criteria for purchasing ....as i already have an old non-camera iphone with pleco installed (transferred from my windows mobile).
First off, are you running the latest version of Pleco (2.2.0)? You can check on that in the Settings tab / About - OCR won't work at all in earlier versions. If you're running an older version, you can update via the "Updates" tab in App Store.
If you are running the latest version, I'm not sure why OCR wouldn't be coming up in the file catalog - the catalog listing is actually generated entirely by our server, not by Apple's (they just fill in the prices), so there's not really any possibility that a particular iTunes store / phone localization / etc might be getting in the way. Do other catalog items (e.g. those in the "Free" section of Add-ons) still show up correctly?
