IBM has developed a text and command input method for handheld mobile devices.
The company maintains that mobile devices currently lack efficient methods of text input and command/function selection. Called Shark, the shorthand method allows a user to trace the letters with a pen on the keyboard to enter a word or command.
Shark shorthand takes advantage of a novel pattern recognition technology, allowing it to use modern digital processing capabilities to compute the statistical constraints represented by the legitimate 'sokgraphs' on the stylus keyboard.
A sokgraph is the trajectory of a word defined on a stylus keyboard layout.
