Abstract
This chapter presents a case study of the redesign of the mobile phone keypad graphics that support the Motorola iTap™ stroke-based Chinese input solution. Six studies were conducted to address problem identification, proof of concept evaluation, usability testing in both US and China, and design simplification to support business objectives. Study results confirmed that a new abstract-with-examples design helped users to develop more accurate knowledge regarding stroke-to-key mappings and lead to significant improvements in both text-entry speed and accuracy. The data also showed that, when using the new keypad graphics, the stroke-based input method could outperform the popular Pinyin technique after about 1 hour of casual usage, making the stroke method a competitive alternative for Chinese entry on mobile phones.
