Small form factor devices, such as cell phones, pose a variety of text entry problems. This talk introduces a new, easy-to-use Chinese text input solution for mobile devices. This unique text entry method uses handwritten phonetic input rather than handwritten ideograms. With the phonetic method, the user is able to write any Chinese character, Traditional or Simplified, using finger movement on a capacitive touch-sensitive surface that is mounted under a standard cell phone keymat. This talk also describes the Machine Learning techniques used to build the character recognition engines for the Chinese and English alphabets.
