Sony Ericsson Chinese smartphone users can now benefit from the speed and natural ease of Decuma handwriting

Zi Corporation (TSX:ZIC)(NASDAQ:ZICA), a leading provider of intelligent interface solutions, today announced its natural handwriting recognition technology Decuma® is now available in Simplified Chinese for purchase by Chinese consumers as a download product for the first time. This is a significant first as Decuma Simplified Chinese (SC) has previously only been available for Original Equipment Manufacturers (OEMs) to embed in devices. The decision by Zi to make Decuma SC directly available to phone users has been driven by huge popular demand from the download community.

Now available for consumer download through Handango and its more than 100 download portals, Decuma enables users to increase the speed and accuracy of a smartphone's handwriting input mode. Zi Corporation will be demonstrating the Decuma languages at CommunicAsia, Stand 3K1-08 in the Canadian Pavilion.

"The capability of directly downloading Decuma SC to their handsets will deliver an intuitive and rapid input, similar to writing characters with pen on paper to Chinese phone users," commented Milos Djokovic, chief operating officer of Zi Corporation, "Zi already offers direct downloading of other products in its portfolio but, given the enormous potential of the Chinese mobile market which is already the largest in the world, this is a very significant step forward."

Decuma SC allows the Chinese phone user to easily and quickly enter words and phrases into his mobile phone using a unique, patented graphical user interface. Decuma SC provides a focused writing process by recognizing the characters where they are written and offering a candidate list at the same point of attention enabling a user to focus on one place. Because Decuma SC writing, character recognition and editing are all contained in a compact box-based display area on the phone's screen, the user can concentrate solely on writing. There is no need for the user to write a single character in and look up to where that character is displayed in another area of the phone display.

Decuma SC is compatible for downloading and use on Sony Ericsson P802, P908 and P910c mobile phones (the Chinese versions of the P800, P900 and P910 handsets). It is based on the Symbian OS and utilizes UIQ Technology.

To trial or purchase the Decuma SC technology, users may visit Handango.com. For additional product information, visit www.zicorp.com.

Editor's Notes

The Decuma SC handwriting recognition technology implements the following Chinese localization features:

- The Decuma SC user interface (or display area on the phone) is a box-based display. After entering in a character in a box, Decuma SC will recognize and present the most likely candidate in the boxed area. Alternative candidates are easily accessible by tapping on the box corner for quick selection.

- Decuma SC allows editing features such as 'back stroke' to delete recognized characters or strokes.

- Decuma SC has a speed write feature, which enables the user to continuously write strings of characters one after the other in the boxes from left to right. After filling in the last box, simply go back to the left side and continue writing over again.

- The Decuma SC user interface is expandable to two large boxes instead of three smaller ones for easy writing of very complicated characters with a many strokes.

- The Word Association feature of Decuma SC allows the user to more quickly complete the next character.

- User personalization features of Decuma SC include the ability for the user to add his own symbols/ to the database through the Shortcut/My Symbol feature.

- Decuma SC includes recognition of latin letters, symbols and numerics

Decuma Simplified Chinese handles natural variations in Chinese writing styles including; printed, semi-cursive and common cursive. Printed style is when a character is written stroke by stroke in sequence. Semi-cursive style is when several or all strokes of an element are drawn as a single continuous stroke. Common cursive is when a whole character is drawn with one or two strokes. Decuma Chinese can recognize a broad range of entered characters, all within a single input screen.
