CharacTell has developed breakthrough handwriting recognition technologies
based on a totally new recognition methodology. We call it
ACR - Advanced Character Recognition.
Only ACR can learns new fonts, character sets, many languages, or even
users' unique handwriting styles, quickly while achieving a high recognition rate
after training on only a few samples. The reason for this success is rooted in the
underlying algorithms, which implement an innovative approach to the recognition problem.
Up to today, the recognition of lower case letters was considered unsolvable.
Human handwriting includes many letters that may have ambiguous meanings.
For example, some people write the letter "e" or "r" in exactly the same way that
others write the letter "c" or "v", respectively. Only CharacTell's approach can recognize
such problematic characters.
Ordinary handwriting recognition products achieve about 85% recognition rates for
mixed upper- and lowercase letters (non-connected) and about 90% for upper cases
only. This means that almost every second word requires human correction. Meanwhile,
research has shown that people find handwriting recognition software to be useful only
when it succeeds in recognizing over 97% to 98% of the characters.
The results achieved by CharacTell's technology are outstanding: in most instances,
the success rate for mixed upper and lower (non-cursive) characters is around 98%, and
for upper cases only, it is near 99%! Such a success rate in character recognition means
that only one word in about every 2 lines will require human correction.
In contrast to the simple operation procedure, the algorithmic tasks running the
program are very complex. The software recognizes the handwriting of the user from a
scanned document by using several recognition engines with a voting mechanism. It then
compares the recognized text with dictionaries, and the ambiguous words are transferred
to the user for correction. Furthermore, a learning procedure is applied at the end of the
scanning in order to refine the engine's learning of the user's handwriting style, which serves
to improve the subsequent results.
