Handwriting recognition SDK for Microsoft Windows

With CalliGrapher SDK, ISVs, VARs, SIs can fine tune natural handwriting input to their custom application needs. For example, a developer of form application for pen-based devices can define different handwriting recognition modes (such as separate letters/cursive/numbers) and custom vocabularies (medical, personal names, cities, etc.) for different fields of a form. In most cases, customization substantially increases input convenience, recognition accuracy, and speed.
