Digi-Pen: Pen Computing Solution By Jae-won Kim Digi-Pen is a new-concept communication solution that Connectrix developed, based on Connectrix's Digi-Ink technology, for sharing visual information. Digi-Pen transfers or shares information, which is difficult to display with traditional communication methods, with minimal amount of data transmission required. In order to explain Digi-Pen, we first have to understand what Digi-Ink technology is. Digi-Ink Digi-Ink is a group of coordinated data drawn from the pen traces made on a touch-screen. It displays a character written or a picture drawn by a user like an image file, so it can enables diverse displays that can not be portrayed with simple text. There is a significant difference between regular image files and Connectrix's Digi-Ink in terms of data storage. Whereas any regular image file saves all pixel information and displays the image by rearranging it, Digi-Ink only stores the coordinates and the order of the pen trajectory. Therefore, the data size is substantially smaller than that of an image file. The principle of Digi-Ink was released in the early 90s, and it has been mainly used for memo-writing solutions. However, with the recent adventages of wireless PDAs, Digi-Ink is coming up as a new solution for mobile communication. Its small data requirement facilitates application in relatively slow wireless networks, and its pen writing mechanism is satisfactory for the wireless device environment. Moreover, it features easy editing in stroke units, active data displays and easy links to voice and video mail. Connectrix utilized this Digi-Ink technology in wireless PDAs and PCs, as well as existing services including chatting and e-mail. With these advantages, Digi-Ink is providing new business models for wireless service providers who are looking for new core services to wireless Internet users. And Digi-Pen now provides Connectrix Messenger, Chatting, and Mail features:
With Connectrix Digi-Pen's services distinguished from other companies traditional PDA solutions, it will enrich PDA data services among different types of devices (PDAs, cellular phones, PCs, eBooks, etc). E-mail us at connectrix_update@connectrix.com
