Graffiti (Palm OS)

from Wikipedia, the free encyclopedia
Graffiti input gestures for Palm OS

Graffiti is a software for recognizing handwritten character input, which is mainly used for data input on PDAs with the Palm OS operating system . There are implementations for other PDA operating systems that can be installed as an alternative input method. The Japanese company Access , which acquired the rights when purchasing PalmSource in 2005, released a variant for Android in 2010 . With this, entries in Japanese script are possible.

Input area in the lower part of the touchscreen

Graffiti recognizes a simplified font, derived from uppercase block letters, which is written with a stylus on a touchscreen . Letters, numbers and special characters that are difficult to recognize, such as B. "A", "F", "K", "T", "4" and "%" are written in a simplified manner. On devices with Palm OS, an area of ​​the touchscreen is permanently set up for entering characters, from which the right part is separated for entering digits. The input area is displayed for other operating systems.

In 1997, Xerox successfully sued the then owner of Palm , US Robotics, which was later bought by 3Com, for patent infringement. Palm was banned from further using graffiti, whereupon Palm marketed a new, licensed handwriting recognition software under the name "Graffiti 2". This was first used in the Tungsten series (Palm OS 5).
