Training
Training is optional for a recognizer and the method of its implementation is
up to the developer. Through training, a recognizer can consider the individual
style and writing characteristics of different users when interpreting
handwriting.
Training can be classified as either passive or active. However, the
distinction usually pertains more to the application than to the recognizer. In passive
training, the application quietly calls the recognizer's training functions
whenever the user corrects a wrong guess. Correctly implemented, passive training
helps ensure that the recognizer learns from its mistakes.
Active training takes place only when specifically requested by the user. A
training window prompts the user for written samples, then the verified input is
given to the recognizer to store in its database for that user. The recognizer
can provide the active training support, though usually this task is left to an
application. Microsoft usability studies have shown that users do not object
to the time invested in active training.
The following table lists the functions that a recognizer with training
capabilities can export. Only TrainHREC is used by version 2.0 Pen API. The other functions are obsolete in version
2.0 and should be included in a recognizer only if it is expected to work with
older applications that work with a version 1.0 recognizer (see the Microsoft
Pen Windows version 1.0 documentation for descriptions of these functions).
Function
| Description
| TrainContextInternal
| Passes a previous recognition result that may contain errors along with the
required interpretation. The system calls this function in response to a call to TrainContext. This function applies only to training recognizers compatible with version
1.0 of the Pen API. It is superseded by the TrainHREC function.
| TrainHREC
| Passes ink data and its required interpretation to the recognizer. The
recognizer then stores the data and interpretation for future reference.
| TrainInkInternal
| Passes a previous erroneous recognition result along with the correct
interpretation. The system calls this function when the application calls TrainInk. TrainInkInternal is rendered obsolete by TrainHREC and is only for training recognizers compatible with version 1.0 of the Pen
API.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
