Recognition: Advanced Topics
10-8 Using Advanced Topics in Recognition
■ using protoRecToggle views to specify recognition behavior
■ defining single-letter input areas within a view
■ accessing text correction information
■ using custom dictionaries for recognition
■ manipulating the review dictionary (includes the user dictionary, expand
dictionary, and auto-add dictionary)
■ using protoCharEdit views for correcting text
■ using stroke bundles
Using recConfig Frames 10
This section describes how to use a recConfig frame to specify a view’s
recognition behavior. Note that the use of view flags is generally the best (and
simplest) way to configure views to recognize common input such as words and
shapes. You need not use a
recConfig frame unless you require some recognition
behavior that cannot be provided using the view’s viewFlags and
dictionaries slots. For example, the use of a recConfig frame is required for
views that restrict recognition of individual characters to a specified set, or
implement customized forms of deferred recognition.
This section describes the use of recConfig frames for
■ enabling recognizers
■ supporting ink text
■ fine-tuning recognition options
■ specifying the dictionaries used for recognition
A recConfig frame can be used to specify any set of recognizers and
dictionaries, including combinations not supported by the view flag model;
however, views controlled by
recConfig frames are subject to the same
limitations as all views that perform recognition:
■ The text recognizer (printed or cursive) made available to all views is determined
by the value of the
letterSetSelection slot in the system’s user
configuration data. Individual views cannot override this system-wide setting.
■ The system’s ability to save learning data is enabled by the value of the
learningEnabledOption slot in the system’s user configuration data.
Individual views cannot override this system-wide setting.
Do not include letterSetSelection or learningEnabledOption slots in
your recConfig frame.
