Handwriting recognition

Handwriting recognition is the ability of a computer to receive and interpret intelligible handwritten input. The image of the written text may be sensed for example by a pen-based interactive whiteboard surface. On-line handwriting recognition involves the automatic conversion of text as it is written on the interactive whiteboard, where a sensor picks up the pen-tip movements as well as pen-up/pen-down switching. That kind of data is known as digital ink and can be regarded as a dynamic representation of handwriting. The obtained signal is converted into letter codes which are usable within computer and text-processing applications.

The elements of an on-line handwriting recognition interface typically include:

  • A pen or stylus for the user to write with
  • A touch sensitive surface, which may be integrated with, or adjacent to, an output display.
  • A software application which interprets the movements of the stylus across the writing surface, translating the resulting curves into digital text

The handwriting recognition feature provides an opportunity to create various types of activities for example see Morning News below.
