Description of the Technology:

With 63.4 million hand-held devices expected to be sold in 2004, the popularity of these devices is
expanding worldwide. Although the use of hand-held devices is increasing, the current input technology
burdens the user because they face a steep learning curve, are unable to input text in their natural style,
and must use character by character input. This is where E-Writer comes in.

  1. User Inputs - User writes in normal script and the writing appears on the screen.
  2. Word Display - E-Writer then processes the script and presents the most likely word by computing an
    internally generated candidate list of ranked confidence values.
  3. Correction - If E-Writer displays the incorrect word, the user accesses the candidate list and chooses the
    correct word.

Features and Benefits:

  • The only handwriting software solution with scalable technology enabling use in both low-end devices
    (PDA’s, Smartphones, etc.) and high-end devices (Pocket PCs, Tablet PCs).
  • It currently offers the only natural script handwriting recognition in the low-end device market, an area with
    explosive growth opportunities.
  • It quickly learns the user’s own handwriting and has the potential to learn any alphabet.
  • It has the ability to input data without a keyboard.


  • Manufacturers of PDA’s (Palm, Visor, Casio, RIM).
  • Manufacturers of Smart Phones (Motorola, Nokia, Ericsson).
  • Manufacturers of Tablet PCs (Microsoft, Sony, Hitachi, AT Cross).

Patent Status:

U.S. and international patent applications pending.
