The application allows a user to enter arbitrary text (Chinese, Latin letter sets are supported) by drawing a character shape on the iPhone screen. As the user draws a letter, the software is promised to recognize it after a brief pause and enters the recognized letter into whatever text field a cursor is currently positioned. For each recognized character, HWPen offers similar recognized, so you could quickly correct your input. We were not able to figure out whether the software is actually “learning” a user’s handwriting.
