Abstract
A system, method and apparatus are described herein for input of characters into a mobile device. In one implementation, a user can input representations of character strokes of logographic characters, such as Chinese characters, using a trackpad module. The system can then associate the character strokes with a character the user desires to input based on the received inputs and a series of well-known rules for writing the logographic characters. One implementation of the trackpad includes an optical trackpad comprising a plurality of sub-sections that can be used to determine the direction of movement of an object over the optical trackpad, for example, a finger over the optical trackpad.
