io - General Discussion

[MarcC]

I just installed my io2 on my new laptop (installation went cleanly, happily for me). I completed the handwriting training successfully on the first pass, with 96% word recognition and 83% sentence recognition.

I just tried writing 10 pages of longhand. The recognition was terrible. I would have spent less time if I had written the pages longhand and then manually typed them in, instead of using Anoto and painfully working my way through the correction interface.

What should I be doing to greatly improve the handwriting recognition? I am willing to modify my handwriting, if someone will only (please!) tell me how and what to do. Am I writing too fast? Am I writing too small? Should I be repeating the training exercise after I modify my handwriting to (somehow) make Anoto happier? Is there some feedback buried somewhere in the Anoto system that I can use to help give it hints or that I can use to have it give me hints on how it wants me to write?

Are the posted samples of what Anoto considers "good" cursive handwriting?

Do I need to leave more spaces between my words?

HELP!

Hi Marc,

proper space between words and proper space between lines should help. Speed is, as far as I know, not an issue, if the text looks ok on the screen, there should be no problem.

Unfortunately, I have not yet see examples of "good" handwriting. Try smaller amounts of text to see what help for better recognition.

I assume, you have version 4.1 of io2 software and version 1.8 of myscript notes?

Regards, Hendrik

[MarcC]

Yes, I have all the most current software versions.

Yes, leaving more space between letters in the same word and leaving much more space between words than I had been doing helps considerably.  Thank you.

I just had a thought.  I may have misunderstood the instructions for writing out the samples for the user profile.  The first part of the profile consists of writing individual letters, not joined together.  Are these individual letters supposed to be printed letters or cursive letters (with spaces between them, not joined together)?

after writing the test-patterns you will see the results of the verification as a table showing the letters of the test-pattern together with your written letter. if they match, all is done well so far

if you prefer to write cursive when useing the io-pen, then you should write the test-patterns also cursive

[Hendrik]

The individual letters are supposed to be printed or cursive, as you usually write, but they need to have spaces between them, not joined.

When you do write the sentences, you should write like you normally write, joined or "unjoined".

Thank you.  I had been printing all my individual letters, and then writing the test sentences for the profile using only cursive.  I only write in cursive in real life.  I will go back and make another profile using a mixture of printed and cursive single characters.

In the past, every time I have created a profile I have gotten 100% recognition of characters but only perhaps 88% or 90% sentence recognition.  All my problems with recognition in the profile creation process seem to have been associated with my cursive sentences.

I am still looking for tips and methods that will work.  At this point, despite my having spent dozens of hours trying to reverse engineer the undocumented requirements of the handwriting recognition algorithms, it is still faster for me to write my notes with a regular pen on regular paper, and then manually retype them into the computer.  It is significantly faster for me to write my notes with a regular pen on regular paper and then dictate them into my laptop using Dragon NaturallySpeaking version 9.  So far, despite my having built many profiles and filled several expensive Anoto paper notebooks trying to deduce what the handwriting algorithm wants and what I need to change in m handwriting to make the undocumented algorithms happy, my Logitech io2 is less than useless to me (it was supposed to be faster than manually retyping all my notes, and it has yet to achieve that modest goal). 

Is there some method to turn off profiles and then look at which characters the algorithm has not recognized?  I suspect that my problems are occurring before the profile is built, as I believe the profile tries to adopt between the ideal handwriting and my own handwriting.  If I could somehow figure out the undocumented ideal handwriting, I could take steps to adapt my own handwriting to more closely match the algorithm's ideal.

Today, despite 100% recognition on individual characters and high 90% recognition on my sentences in my profiles, I get 2 or 3 recognition errors per written line of my every-day real text.  The tear-jerkingly slow-to-use io2 text optimization window lacks a spelling checker and lacks a grammar checker, so I have to carefully read every word to look for single-character misrecognition.  The text window does not give me any hint as to what the algorithm thought the word I wrote was (unlike Dragon NaturallySpeaking, which gives me an ordered list of what the speech-recognition algorithm algorithm thought I said). 

If I copy the text over into Microsoft Word to use the spelling and grammar checker, and then copy and past the corrected text back into the io2 window, the binding between the text and my handwriting is apparently lost.  But I explicitly bought the io2 system to get the search capabilities to search my notes for keywords and then be able to find my many hand-drawn sketches and diagrams.  Maybe I am missing something here.

Come on, people, there must be some documentation or some examples of 100% recognized handwriting or something out there some where.  Can some one please help me?
