Donuts – Pen-Based Chinese Input Interfacedonuts

Handwriting recognition is often considered an ideal solution for pen-based Chinese input. However, handwriting Chinese suffers from the performance bottleneck due to the complex structure of Chinese characters.

We designed Donuts, a technique that allows an user to enter Chinese characters by navigating through a hierarchical marking menu of phonetic symbols. In particular, to place 12 vowels into a marking menu while keeping the performance, we designed a pressure-sensitive marking menu to organize the 12 vowels into two pressure-sensitive layers.

Informal feedback and a theoretical prediction of performance indicated that Donuts is a promising technique for Chinese input.
