Yikai Guo, Jiahuan He, Rongtian Bai, Zhengyang Wu, Yuhang Huang · 2024
This paper presents a novel T9 keyboard layout designed specifically for Chinese users, considering the influence of the Pinyin system. The traditional T9 layout, originally developed for English typing, is inefficient for Chinese input, leading to a higher cognitive load and reduced typing speed. Our proposed layout optimizes key placement based on the frequency and distribution of Pinyin syllables, incorporating intuitive methods for inputting tone markers. By minimizing keystrokes and enhancing ergonomic design, the new layout aims to improve typing efficiency and comfort. We conducted comprehensive evaluations comparing the new layout with traditional methods, showing significant improvements in input speed and user satisfaction. This research highlights the importance of tailoring keyboard designs to specific language requirements, contributing to the broader field of human-computer interaction and providing a better typing experience for Chinese users.
