Recognition 6

The Newton operating system is able to recognize handwriting, printing,

and drawing, transforming it into typeset, editable text or editable geometric

shapes. The Newton system can also recognize a common set of pen gestures

for correcting and editing input. The recognition system has a sophisticated

multiple-recognizer architecture. There are separate recognizers for words,

geometric shapes, and gestures, any of which an application can make simul-

taneously active. An arbitrator in the recognition system examines the results

from simultaneously active recognizers and returns the recognition match

that has the highest conﬁdence.

The text recognizers can handle printed, cursive, or mixed handwriting.

They can work together with built-in dictionaries to choose words that

accurately match what a user has written, and they can recognize a user’s

writing letter by letter. A user can also add new words to a personal dictionary.

The shape recognizer recognizes both simple and complex geometric objects,

cleaning up rough drawings into shapes with straight lines and smooth

curves. The shape recognizer also recognizes symmetry, using that property,

if present, to help it recognize and display objects.
